Remove slow paths from pow
Remove the slow paths from pow. Like several other double precision math functions, pow is exactly rounded. This is not required from math functions and causes major overheads as it requires multiple fallbacks using higher precision arithmetic if a result is close to 0.5ULP. Ridiculous slowdowns of up to 100000x have been reported when the highest precision path triggers. All GLIBC math tests pass on AArch64 and x64 (with ULP of pow set to 1). The worst case error is ~0.506ULP. A simple test over a few hundred million values shows pow is 10% faster on average. This fixes BZ #13932.

Add narrowing add functions.
This patch adds the narrowing add functions from TS 18661-1 to glibc's libm: fadd, faddl, daddl, f32addf64, f32addf32x, f32xaddf64 for all configurations; f32addf64x, f32addf128, f64addf64x, f64addf128, f32xaddf64x, f32xaddf128, f64xaddf128 for configurations with _Float64x and _Float128; __nldbl_daddl for ldbl-opt. As discussed for the build infrastructure patch, tgmath.h support is deliberately deferred, and FP_FAST_* macros are not applicable without optimized function implementations. Function implementations are added for all relevant pairs of formats (including certain cases of a format and itself where more than one type has that format). The main implementations use round-to-odd, or a trivial computation in the case where both formats are the same or where the wider format is IBM long double (in which case we don't attempt to be correctly rounding). The sysdeps/ieee754/soft-fp implementations use soft-fp, and are used automatically for configurations without exceptions and rounding modes by virtue of existing Implies files. As previously discussed, optimized versions for particular architectures are possible, but not included. i386 gets a special version of f32xaddf64 to avoid problems with double rounding (similar to the existing fdim version), since this function must round just once without an intermediate rounding to long double. (No such special version is needed for any other function, because the nontrivial functions use round-to-odd, which does the intermediate computation with the rounding mode set to round-to-zero, and double rounding is OK except in round-to-nearest mode, so is OK for that intermediate round-to-zero computation.) mul and div will need slightly different special versions for i386 (using round-to-odd on long double instead of precision control) because of the possibility of inexact intermediate results in the subnormal range for double. To reduce duplication among the different function implementations, math-narrow.h gets macros CHECK_NARROW_ADD, NARROW_ADD_ROUND_TO_ODD and NARROW_ADD_TRIVIAL. In the trivial cases and for any architecture-specific optimized implementations, the overhead of the errno setting might be significant, but I think that's best handled through compiler built-in functions rather than providing separate no-errno versions in glibc (and likewise there are no __*_finite entry points for these function provided, __*_finite effectively being no-errno versions at present in most cases). Tested for x86_64 and x86, with both GCC 6 and GCC 7. Tested for mips64 (all three ABIs, both hard and soft float) and powerpc with GCC 7. Tested with build-many-glibcs.py with both GCC 6 and GCC 7. * math/Makefile (libm-narrow-fns): Add add.

Add test infrastructure for narrowing libm functions.
This patch continues preparations for adding TS 18661-1 narrowing libm functions by adding the required testsuite infrastructure to test such functions through the libm-test infrastructure. That infrastructure is based around testing for a single type, FLOAT. For the narrowing functions, FLOAT, the "main" type for testing, is the function return type; the argument type is ARG_FLOAT. This is consistent with how the code built once for each type, libm-test-support.c, depends on FLOAT for such things as calculating ulps errors in results but can already handle different argument types (pointers, integers, long double for nexttoward). Makefile machinery is added to handle building tests for all pairs of types for which there are narrowing functions (as with non-narrowing functions, aliases are tested just the same as the functions they alias). gen-auto-libm-tests gains a --narrow option for building outputs for narrowing functions (so narrowing sqrt and fma will share the same inputs as non-narrowing, but gen-auto-libm-tests will be run with and without that option to generate different output files). In the narrowing case, the auto-libm-test-out-narrow-* files include annotations for each test about what properties ARG_FLOAT must have to be able to represent all the inputs for that test; those annotations result in calls to the TEST_COND_arg_fmt macro. gen-libm-test.pl has some minor updates to handle narrowing tests (for example, arguments in such tests must be surrounded by ARG_LIT calls instead of LIT calls). Various new macros are added to the C test support code (for example, sNaN initializers need to be properly typed, so arg_snan_value is added; other such arg_* macros are added as it seems cleanest to do so, though some are not strictly required). Special-casing of the ibm128 format to allow for its limitations is adjusted to handle it as the argument format as well as as the result format; thus, the tests of the new functions allow nonzero ulps only in the case where ibm128 is the argument format, as otherwise the functions correspond to fully-defined IEEE operations. The ulps in question appear as e.g. 'Function: "add_ldouble"' in libm-test-ulps (with 1ulp errors then listed for double and float for that function in powerpc); no support is added to generate corresponding faddl / daddl ulps listings in the ulps table in the manual. For the previous patch, I noted the need to avoid spurious macro expansions of identifiers such as "add". A test test-narrow-macros.c is added to verify such macro expansions are successfully avoided, and there is also a -mlong-double-64 version of that test for ldbl-opt. This test is set up to cover the full set of relevant identifiers from the start rather than adding functions one at a time as each function group is added. Tested for x86_64 (this patch in isolation, as well as testing for various configurations in conjunction with the actual addition of "add" functions). * math/Makefile (test-type-pairs): New variable.

Add build infrastructure for narrowing libm functions.
TS 18661-1 defines libm functions that carry out an operation (+ - * / sqrt fma) on their arguments and return a result rounded to a (usually) narrower type, as if the original result were computed to infinite precision and then rounded directly to the result type without any intermediate rounding to the argument type. For example, fadd, faddl and daddl for addition. These are the last remaining TS 18661-1 functions left to be added to glibc. TS 18661-3 extends this to corresponding functions for _FloatN and _FloatNx types. As functions parametrized by two rather than one varying floating-point types, these functions require infrastructure in glibc that was not required for previous libm functions. This patch provides such infrastructure - excluding test support, and actual function implementations, which will be in subsequent patches. Declaring the functions uses a header bits/mathcalls-narrow.h, which is included many times, for each relevant pair of types. This will end up containing macro calls of the form __MATHCALL_NARROW (__MATHCALL_NAME (add), __MATHCALL_REDIR_NAME (add), 2); for each family of narrowing functions. (The structure of this macro call, with the calls to __MATHCALL_NAME and __MATHCALL_REDIR_NAME there rather than in the definition of __MATHCALL_NARROW, arises from the names such as "add" *not* themselves being reserved identifiers - meaning it's necessary to avoid any indirection that would result in a user-defined "add" macro being expanded.) Whereas for existing functions declaring long double functions is disabled if _LIBC in the case where they alias double functions, to facilitate defining the long double functions as aliases of the double ones, there is no such logic for the narrowing functions in this patch. Rather, the files defining such functions are expected to use #define to hide the original declarations of the alias names, to avoid errors about defining aliases with incompatible types. math/Makefile support is added for building the functions (listed in libm-narrow-fns, currently empty) for all relevant pairs of types. An internal header math-narrow.h is added for macros shared between multiple function implementations - currently a ROUND_TO_ODD macro to facilitate writing functions using the round-to-odd implementation approach, and alias macros to create all the required function aliases. libc_feholdexcept_setroundf128 and libc_feupdateenv_testf128 are added for use when required (only for x86_64). float128_private.h support is added for ldbl-128 narrowing functions to be used for _Float128. Certain things are specifically omitted from this patch and the immediate followups. tgmath.h support is deferred; there remain unresolved questions about how the type-generic macros for these functions are supposed to work, especially in the case of arguments of integer type. The math.h / bits/mathcalls-narrow.h logic, and the logic for determining what functions / aliases to define, will need some adjustments to support the sqrt and fma functions, where e.g. f32xsqrtf64 can just be an alias for sqrt rather than a separate function. TS 18661-1 defines FP_FAST_* macros but no support is included for defining them (they won't in general be true without architecture-specific optimized function versions). For each of the function groups (add sub mul div sqrt fma) there are always six functions present (e.g. fadd, faddl, daddl, f32addf64, f32addf32x, f32xaddf64). When _Float64x and _Float128 are supported, there are seven more (e.g. f32addf64x, f32addf128, f64addf64x, f64addf128, f32xaddf64x, f32xaddf128, f64xaddf128). In addition, in the ldbl-opt case there are function names such as __nldbl_daddl (an alias for f32xaddf64, which is not a reserved name in TS 18661-1, only in TS 18661-3), for calls to daddl to be mapped to in the -mlong-double-64 case. (Calls to faddl just get mapped to fadd, and for sqrt and fma there won't be __nldbl_* functions because dsqrtl and dfmal can just be mapped to sqrt and fma with -mlong-double-64.) While there are six or thirteen functions present in each group (plus __nldbl_* names only as an ABI, not an API), not all are distinct; they fall in various groups of aliases. There are two distinct versions built if long double has the same format as double; four if they have distinct formats but there is no _Float64x or _Float128 support; five if long double has binary128 format; seven when _Float128 is distinct from long double. Architecture-specific optimized versions are possible, but not included in my patches. For example, IA64 generally supports narrowing the result of most floating-point instructions; Power ISA 2.07 (POWER8) supports double values as arguments to float instructions, with the results narrowed as expected; Power ISA 3 (POWER9) supports round-to-odd for float128 instructions, so meaning that approach can be used without needing to set and restore the rounding mode and test "inexact". I intend to leave any such optimized versions to the architecture maintainers. Generally in such cases it would also make sense for calls to these functions to be expanded inline (given -fno-math-errno); I put a suggestion for TS 18661-1 built-in functions at <https://gcc.gnu.org/wiki/SummerOfCode>.

Reduce command length in regen-ulps.
I found that "make regen-ulps" failed when building with unmodified GNU make 4.1, and an objdir /some/where/math/ longer than about 37 characters, because the list of tests in the "for run in $^" loop exceeded the Linux kernel's MAX_ARG_STRLEN limit (131072 bytes) on the length of a single argument passed to a command. Some GNU/Linux distributions have a patch to make to work around this limit (see e.g. Debian bug 688601), but clearly this ought to work without needing such a patch. This patch arranges for the shell loop to be over the test names without a $(objdir) prefix, which reduces the space used to less than half MAX_ARG_STRLEN. (I think we ought to aim to get rid of bits/mathinline.h completely - filing GCC bugs for any optimizations GCC can't currently do with -ffast-math - which would mean we could halve the number of libm tests run because separate inline function tests would no longer be needed. However, with a long directory name even half the number of tests could make this command exceed MAX_ARG_STRLEN without my patch.) Tested regen-ulps on a system where it failed before this patch. * math/Makefile (run-regen-ulps): Add $(objpfx) to test name here. (regen-ulps): Use $(libm-tests) not $^ in shell loop. |

Provide a C++ version of iseqsig (bug 22377)
In C++ mode, __MATH_TG cannot be used for defining iseqsig, because __MATH_TG relies on __builtin_types_compatible_p, which is a C-only builtin. This is true when float128 is provided as an ABI-distinct type from long double. Moreover, the comparison macros from ISO C take two floating-point arguments, which need not have the same type. Choosing what underlying function to call requires evaluating the formats of the arguments, then selecting which is wider. The macro __MATH_EVAL_FMT2 provides this information, however, only the type of the macro expansion is relevant (actually evaluating the expression would be incorrect). This patch provides a C++ version of iseqsig, in which only the type of __MATH_EVAL_FMT2 (__typeof or decltype) is used as a template parameter for __iseqsig_type. This function calls the appropriate underlying function. Tested for powerpc64le and x86_64. [BZ #22377] * math/Makefile [C++] (tests): Add test for iseqsig. * math/math.h [C++] (iseqsig): New implementation, which does not rely on __MATH_TG/__builtin_types_compatible_p. * math/test-math-iseqsig.cc: New file. * sysdeps/powerpc/powerpc64le/Makefile (CFLAGS-test-math-iseqsig.cc): New variable. |

Improve __ieee754_exp() performance by greater than 5x on sparc/x86.
These changes will be active for all platforms that don't provide
their own exp() routines. They will also be active for ieee754
versions of ccos, ccosh, cosh, csin, csinh, sinh, exp10, gamma, and
erf.
Typical performance gains is typically around 5x when measured on
Sparc s7 for common values between exp(1) and exp(40).
Using the glibc perf tests on sparc,
sparc (nsec) x86 (nsec)
old new old new
max 17629 395 5173 144
min 399 54 15 13
mean 5317 200 1349 23
The extreme max times for the old (ieee754) exp are due to the
multiprecision computation in the old algorithm when the true value is
very near 0.5 ulp away from an value representable in double
precision. The new algorithm does not take special measures for those
cases. The current glibc exp perf tests overrepresent those values.
Informal testing suggests approximately one in 200 cases might
invoke the high cost computation. The performance advantage of the new
algorithm for other values is still large but not as large as indicated
by the chart above.
Glibc correctness tests for exp() and expf() were run. Within the
test suite 3 input values were found to cause 1 bit differences (ulp)
when "FE_TONEAREST" rounding mode is set. No differences in exp() were
seen for the tested values for the other rounding modes.
Typical example:
exp(-0x1.760cd2p+0) (-1.46113312244415283203125)
new code: 2.31973271630014299393707e-01 0x1.db14cd799387ap-3
old code: 2.31973271630014271638132e-01 0x1.db14cd7993879p-3
exp = 2.31973271630014285508337 (high precision)
Old delta: off by 0.49 ulp
New delta: off by 0.51 ulp
In addition, because ieee754_exp() is used by other routines, cexp()
showed test results with very small imaginary input values where the
imaginary portion of the result was off by 3 ulp when in upward
rounding mode, but not in the other rounding modes. For x86, tgamma
showed a few values where the ulp increased to 6 (max ulp for tgamma
is 5). Sparc tgamma did not show these failures. I presume the tgamma
differences are due to compiler optimization differences within the
gamma function.The gamma function is known to be difficult to compute
accurately.

Add _Float32 function aliases.
This patch concludes filling out TS 18661-3 support for different types by adding *f32 function aliases of float functions to support _Float32. As with _Float64 and _Float32x, this is supported for all glibc configurations. As with the previous such patches there are some x86 ulps updates because of inline functions present for float but not for _Float32. The patch also has the usual bits/floatn-common.h update, symbol versions, ABI baselines updates, test enablement and documentation.

Add _Float64, _Float32x function aliases.
This patch continues filling out TS 18661-3 support by adding *f64 and *f32x function aliases, supporting _Float64 and _Float32x, as aliases for double functions. These types are supported for all glibc configurations. The API corresponds exactly to that for _Float128 and _Float64x. _Float32 aliases to float functions remain to be added in subsequent patches to complete this process (then there are a few miscellaneous functions in TS 18661-3 to implement that aren't simply versions of existing functions for new types). The patch enables the feature in bits/floatn-common.h, adds symbol versions and documentation with updates to ABI baselines, and arranges for the libm functions for the new types to be tested. As with the _Float64x changes there are some x86 ulps updates because of header inlines not used for the new types (and one other change to the non-multiarch libm-test-ulps, which I suppose comes from using a different compiler version / configuration from when it was last regenerated). Tested for x86_64 and x86, and with build-many-glibcs.py, with both GCC 6 and GCC 7. * bits/floatn-common.h (__HAVE_FLOAT64): Define to 1.

Remove _Mlong_double_ etc. macros.
math.h has a macro _Mlong_double_ for the type to use when declaring
long double functions, and similar macros for other types.
math/Makefile uses -D_Mlong_double_=double in the case of long double
having the same ABI as double.
This originates with:
Mon Jul 8 13:37:40 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu>
* math/math.h (_Mfloat_, _Mlong_double_): New macros, defined iff not
already defined to float, long double. Use those macros for _Mdouble_
defns when including mathcalls.h.
* math/Makefile [$(long-double-fcts) != yes] (CPPFLAGS): Append
-D_Mlong_double_=double.
However, math.h stopped declaring long double functions in the case of
long double having the same ABI as double (and thus probably stopped
actually needing the Makefile definition of _Mlong_double_) with:
1998-11-05 Ulrich Drepper <drepper@cygnus.com>
* math/math.h: Unconditionally include bits/mathdef.h. Declare
long double functions only if __NO_LONG_DOUBLE_MATH is not
defined.
* sysdeps/generic/bits/mathdef.h: Define only if __USE_ISOC9X.
Define __NO_LONG_DOUBLE_MATH.
* sysdeps/m68k/fpu/bits/mathdef.h: Define only if __USE_ISOC9X.
* sysdeps/i386/fpu/bits/mathdef.h: Likewise.
The declarations were since restored for compiling user code, but
remain absent when _LIBC is defined, which is sufficient to avoid
problems declaring function aliases of incompatible types. Thus the
indirection through the _Mlong_double_ macro is not needed (probably
since that 1998 patch), and this patch removes _Mlong_double_ and
associated macros for other types, leaving only the macro _Mdouble_
which is actually used as the type for which a given inclusion of
<bits/mathcalls.h> should declared functions.
Tested for x86_64, and tested with build-many-glibcs.py that installed
stripped shared libraries are unchanged by this patch.

Add bits/floatn.h defines for more _FloatN / _FloatNx types.
The bits/floatn.h header currently only has defines relating to _Float128. This patch adds defines relating to other _FloatN / _FloatNx types. The approach taken is to add defines for all _FloatN / _FloatNx types known to GCC, and to put them in a common bits/floatn-common.h header included at the end of all the individual bits/floatn.h headers. If in future some defines become different for different glibc configurations, they will move out into the separate bits/floatn.h headers. Some defines are expected always to be the same across glibc ports. Corresponding defines are nevertheless put in this header. The intent is that where there are conditionals (in headers or in non-installed files) that can just repeat the same or nearly the same logic for each floating-point type, they should do so, even if in fact the cases for some types could be unconditionally present or absent because the same conditionals are true or false for all glibc configurations. This should make the glibc code with such conditionals easier to read, because the reader can just see that the same conditionals are repeated for each type, rather than seeing different conditionals for different types and needing to reason, at each location with such differences, why those differences are indeed correct there. (Cases involving per-format rather than per-type logic are more likely still to need differences in how they handle different types.) Having such defines and conditionals also helps in incremental preparation for adding _Float32 / _Float64 / _Float32x / _Float64x function aliases. I intend subsequent patches to add such conditionals corresponding to those already present for _Float128, as well as making more architecture-specific function implementations use common macros to define aliases in preparation for adding such _FloatN / _FloatNx aliases. Tested for x86_64. * bits/floatn-common.h: New file. * math/Makefile (headers): Add bits/floatn-common.h. * bits/floatn.h: Include <bits/floatn-common.h>. * sysdeps/ia64/bits/floatn.h: Likewise. * sysdeps/ieee754/ldbl-128/bits/floatn.h: Likewise. * sysdeps/mips/ieee754/bits/floatn.h: Likewise. * sysdeps/powerpc/bits/floatn.h: Likewise. * sysdeps/x86/bits/floatn.h: Likewise. |

Support running libm tests for float128 as alias for long double.
This patch adds support for running libm tests for float128 in the case where the float128 functions are aliases of long double functions. In this case, the sysdeps Makeconfig file (i.e. sysdeps/ieee754/ldbl-128/Makeconfig) will need to define "float128-alias-fcts = yes" to enable the tests. Tested for x86_64. Also tested with build-many-glibcs.py; installed stripped shared libraries are unchanged by the patch.

Run libm long double tests for long double = double.
All interfaces in the glibc API ought to be covered by the testsuite, even where they alias other interfaces. This patch arranges for libm tests to be run for long double when it aliases double; previously those tests were run only for the floating-point types with distinct formats. The long double tests are made to use the double ulps values in this case, as having a separate duplicate set of ulps for them seems unnecessary; to accommodate that, the test-<type>.h headers now specify the macro indexing into the ulps array explicitly instead of having it computed from PREFIX. Nothing special is done about vector function tests. None are supported for any long double = double platforms, and supporting vector functions for a type alias such as _Float32 would not simply fall out of adding the scalar aliases for that type - it would require vector function wrappers like those for *_finite (or, better, a new GCC feature to allow specifying the asm name for vector functions independently of that for scalar ones, as previously discussed), so it seems reasonable to require the sysdeps makefile setting of libmvec-tests to be updated if any such tests are to be run for type aliases. Tested for x86_64 and arm. * math/Makefile (test-types-basic): New variable. (test-types): Likewise. (libm-test-support): Use $(test-types) instead of $(types). (libm-tests-base-normal): Likewise.

Add C++ versions of iscanonical for ldbl-96 and ldbl-128ibm (bug 22235)
All representations of floating-point numbers in types with IEC 60559 binary exchange format are canonical. On the other hand, types with IEC 60559 extended formats, such as those implemented under ldbl-96 and ldbl-128ibm, contain representations that are not canonical. TS 18661-1 introduced the type-generic macro iscanonical, which returns whether a floating-point value is canonical or not. In Glibc, this type-generic macro is implemented using the macro __MATH_TG, which, when support for float128 is enabled, relies on __builtin_types_compatible_p to select between floating-point types. However, this use of iscanonical breaks C++ applications, because the builtin is only available in C mode. This patch provides a C++ implementation of iscanonical that relies on function overloading, rather than builtins, to select between floating-point types. Unlike the C++ implementations for iszero and issignaling, this implementation ignores __NO_LONG_DOUBLE_MATH. The double type always matches IEC 60559 double format, which is always canonical. Thus, when double and long double are the same (__NO_LONG_DOUBLE_MATH), iscanonical always returns 1 and is not implemented with __MATH_TG. Tested for powerpc64, powerpc64le and x86_64.

Optimized generic expf and exp2f with wrappers
Based on new expf and exp2f code from https://github.com/ARM-software/optimized-routines/ with wrapper on aarch64: expf reciprocal-throughput: 2.3x faster expf latency: 1.7x faster without wrapper on aarch64: expf reciprocal-throughput: 3.3x faster expf latency: 1.7x faster without wrapper on aarch64: exp2f reciprocal-throughput: 2.8x faster exp2f latency: 1.3x faster libm.so size on aarch64: .text size: -152 bytes .rodata size: -1740 bytes expf/exp2f worst case nearest rounding error: 0.502 ulp worst case non-nearest rounding error: 1 ulp Error checks are inline and errno setting is in separate tail called functions, but the wrappers are kept in this patch to handle the _LIB_VERSION==_SVID_ case. (So e.g. errno is set twice for expf calls and once for __expf_finite calls on targets where the new code is used.) Double precision arithmetics is used which is expected to be faster on most targets (including soft-float) than using single precision and it is easier to get good precision result with it. Const data is kept in a separate translation unit which complicates maintenance a bit, but is expected to give good code for literal loads on most targets and allows sharing data across expf, exp2f and powf. (This data is disabled on i386, m68k and ia64 which have their own expf, exp2f and powf code.) Some details may need target specific tweaks: - best convert and round to int operation in the arg reduction may be different across targets. - code was optimized on fma target, optimal polynomial eval may be different without fma. - gcc does not always generate good code for fp bit representation access via unions or it may be inherently slow on some targets. The libm-test-ulps will need adjustment because.. - The argument reduction ideally uses nearest rounded rint, but that is not efficient on most targets, so the polynomial can get evaluated on a wider interval in non-nearest rounding mode making 1 ulp errors common in that case. - The polynomial is evaluated such that it may have 1 ulp error on negative tiny inputs with upward rounding. * math/Makefile (type-float-routines): Add math_errf and e_exp2f_data. * sysdeps/aarch64/fpu/math_private.h (TOINT_INTRINSICS): Define.

Simplify NAN definitions.
Similar to my patches for HUGE_VAL and INFINITY. this patch eliminates
the bits/nan.h headers. __builtin_nanf ("") is used to define NAN for
GCC 3.3 and later; the fallback is (0.0f / 0.0f), which is a constant
expression for a quiet NaN of type float, but raises a spurious
"invalid" exception outside static initializers, which seems the best
that can be done purely in standard C. Again, if anyone actually uses
a compiler with its own incompatible extension for producing a
constant quiet NaN, we can add compiler conditionals.
Tested for x86_64.

Simplify HUGE_VAL definitions.
There are various bits/huge_val*.h headers to define HUGE_VAL and related macros. All of them use __builtin_huge_val etc. for GCC 3.3 and later. Then there are various fallbacks, such as using a large hex float constant for GCC 2.96 and later, or using unions (with or without compound literals) to construct the bytes of an infinity, with this last being the reason for having architecture-specific files. Supporting TS 18661-3 _FloatN / _FloatNx types that have the same format as other supported types will mean adding more such macros; needing to add more headers for them doesn't seem very desirable. The fallbacks based on bytes of the representation of an infinity do not meet the standard requirements for a constant expression. At least one of them is also wrong: sysdeps/sh/bits/huge_val.h is producing a mixed-endian representation which does not match what GCC does. This patch eliminates all those headers, defining the macros directly in math.h. For GCC 3.3 and later, the built-in functions are used as now. For other compilers, a large constant 1e10000 (with appropriate suffix) is used. This is like the fallback for GCC 2.96 and later, but without using hex floats (which have no apparent advantage here). It is unambiguously valid standard C for all floating-point formats with infinities, which covers all formats supported by glibc or likely to be supported by glibc in future (C90 DR#025 said that if a floating-point format represents infinities, all real values lie within the range of representable values, so the constraints for constant expressions are not violated), but may generate compiler warnings and wouldn't handle the TS 18661-1 FENV_ROUND pragma correctly. If someone is actually using a compiler with glibc that does not claim to be GCC 3.3 or later, but which has a better way to define the HUGE_VAL macros, we can always add compiler conditionals in with alternative definitions. I intend to make similar changes for INF and NAN. The SNAN macros already just use __builtin_nans etc. with no fallback for compilers not claiming to be GCC 3.3 or later.

Fix bits/math-finite.h _MSUF_ expansion namespace (bug 22028).
The current bits/math-finite.h approach to defining functions for different types, involving math.h defining _MSUF_ and _MSUFTO_ for the function suffixes involved, is not namespace-clean if one of those suffixes (f, l, f128) is defined as a macro by the user before math.h is included; too many levels of macro expansion occur. Instead, those suffixes should appear directly in the expansion of the macro using ## so they don't get expanded even if defined as macros by the user (that is, math.h should be defining __REDIRFROM_X and __REDIRTO_X directly to use those suffixes rather than suffixes being passed as an argument by macro callers). This patch makes that change. Tested for x86_64. [BZ #22028] * math/math.h [__FINITE_MATH_ONLY__ && __FINITE_MATH_ONLY__ > 0] (_MSUF_): Remove macro.

Provide a C++ version of issignaling that does not use __MATH_TG
The macro __MATH_TG contains the logic to select between long double and _Float128, when these types are ABI-distinct. This logic relies on __builtin_types_compatible_p, which is not available in C++ mode. On the other hand, C++ function overloading provides the means to distinguish between the floating-point types. The overloading resolution will match the correct parameter regardless of type qualifiers, i.e.: const and volatile. Tested for powerpc64le, s390x, and x86_64. * math/math.h [defined __cplusplus] (issignaling): Provide a C++ definition for issignaling that does not rely on __MATH_TG, since __MATH_TG uses __builtin_types_compatible_p, which is only available in C mode.

Obsolete matherr, _LIB_VERSION, libieee.a.
This patch obsoletes support for SVID libm error handling (the system where a user-defined function matherr is called on a libm function error; only enabled if you also set _LIB_VERSION = _SVID_ or _LIB_VERSION = _XOPEN_) and the use of the _LIB_VERSION global variable to control libm error handling. matherr and _LIB_VERSION are made into compat symbols, not supported for new ports or for static linking. The libieee.a object file (which sets _LIB_VERSION = _IEEE_, so disabling errno setting for some functions) is also removed, and all the related definitions are removed from math.h. The manual already recommends against using matherr, and it's already not supported for _Float128 functions (those use new wrappers that don't support matherr, only errno) - this patch means that it becomes possible to e.g. add sinf32 as an alias to sinf without that resulting in undesired matherr support in sinf32 for existing glibc ports. matherr support is not part of any standard supported by glibc (it was removed in XPG4). Because matherr is a function to be defined by the user, of course user programs defining such a function will still continue to link; it just quietly won't be used. If they try to write to the library's copy of _LIB_VERSION to enable SVID error handling, however, they will get a link error (but if they define their own _LIB_VERSION variable, they won't). I expect the most likely case of build failures from this patch to be programs with unconditional cargo-culted uses of -lieee (based on a notion of "I want IEEE floating point", not any actual requirement for that library). Ideally, the new-port-or-static-linking case would use the new wrappers used for _Float128. This is not implemented in this patch, because of the complication of architecture-specific (powerpc32 and sparc) sqrt wrappers that use _LIB_VERSION and __kernel_standard directly. Thus, the old wrappers and __kernel_standard are still built unconditionally, and _LIB_VERSION still exists in static libm. But when the old wrappers and __kernel_standard are built in the non-compat case, _LIB_VERSION and matherr are defined as macros so code to support those features isn't actually built into static libm or new ports' shared libm after this patch. I intend to move to the new wrappers for static libm and new ports in followup patches. I believe the sqrt wrappers for powerpc32 and sparc can reasonably be removed. GCC already optimizes the normal case of sqrt by generating code that uses a hardware instruction and only calls the sqrt function if the argument was negative (if -fno-math-errno, of course, it just uses the hardware instruction without any check for negative argument being needed). Thus those wrappers will only actually get called in the case of negative arguments, which is not a case it makes sense to optimize for. But even without removing the powerpc32 and sparc wrappers it should still be possible to move to the new wrappers for static libm and new ports, just without having those dubious architecture-specific optimizations in static libm. Everything said about matherr equally applies to matherrf and matherrl (IA64-specific, undocumented), except that the structure of IA64 libm means it won't be converted to using the new wrappers (it doesn't use the old ones either, but its own error-handling code instead). As with other tests of compat symbols, I expect test-matherr and test-matherr-2 to need to become appropriately conditional once we have a system for disabling such tests for ports too new to have the relevant symbols.

Add more thorough generated tgmath.h test.
This patch adds a more thorough test of tgmath.h macros, verifying both the return type and the function called for all the cases of valid argument types. (Cases with current problems - I've just filed four bugs - are disabled or omitted pending fixing those problems.) The test uses a Python generator (works with both Python 2 and 3) to generate a C file which is then built and run as a test in the usual way (and that C file includes its own dummy definitions of libm functions similar to existing tgmath.h tests). The motivation is to make it easier to add tests of tgmath.h for _Float128 when adding tgmath.h support for that type; the _FloatN / _FloatNx support is present in the script, but disabled until the tgmath.h support is written. Tested for x86_64, and for arm to check things in the long double = double case. (In that case, it's OK to call either double or long double functions when the selected type is double or long double, as long as the return type of the macro is exactly correct.) * math/gen-tgmath-tests.py: New file. * math/Makefile [PYTHON] (tests): Add test-tgmath3. [PYTHON] (generated): Add test-tgmath3.c. [PYTHON] (CFLAGS-test-tgmath3.c): New variable. [PYTHON] ($(objpfx)test-tgmath3.c): New rule. |

Convert e_exp2l.c into a template
This patch converts the implementation of exp2l in math/e_exp2l.c into a template in math/e_exp2_template.c, then adjusts Makefile to use this template for long double (the implementations for float and double in sysdeps have higher precedence and are not used). This template can also be used for float128, thus reducing the amount of duplicated code that gets added when adding support the new type. Tested for powerpc64le and s390x. * math/Makefile (libm-calls): Move e_exp2F to gen-libm-calls. (gen-libm-calls): Add e_exp2F to use the template. * math/e_exp2l.c: Rename to math/e_exp2_template.c. * math/e_exp2_template.c: New file, renamed from math/e_exp2l.c, and made into a template. * sysdeps/generic/math-type-macros.h (M_MIN_EXP): New macro. |

Split helper classification macros from mathcalls.h
The classification macros: finite, fpclassify, iseqsig, isinf, isnan, issignaling, and signbit are defined by ISO C11 and declared in mathcalls.h for each of the floating-point types: float, double, and long double. TS 18661-3 does not mention these macros for float128, however support for them must be present when _Float128 is present. This is true, even when the feature test macro __STDC_WANT_IEC_60559_TYPES_EXT__ is false. Other function declarations in mathcalls.h, on the other hand, depend on __STDC_WANT_IEC_60559_TYPES_EXT__. This patch splits the helper functions (__finite, __fpclassify, __iseqsig, __isinf, __isnan, __issignaling, and __signbit) from mathcalls.h, so that these helper functions can be declared for _Float128, even when __STDC_WANT_IEC_60559_TYPES_EXT__ is false. Tested for powerpc64le, s390x, and x86_64. * include/bits/mathcalls-helper-functions.h: New file. * math/Makefile (headers): Add bits/mathcalls-helper-functions.h. * math/bits/mathcalls.h (__finite, __fpclassify, __iseqsig) (__isinf, __isnan, __issignaling, __signbit): Move declarations to math/bits/mathcalls-helper-functions.h. * math/bits/mathcalls-helper-functions.h: New file. * math/math.h: Include bits/mathcalls-helper-functions.h for float, double, and long double. |

Run libm tests separately for each function.
At present, libm tests for each function get built into a single executable (for each floating point type, for each of normal / inline / finite-math-only functions, plus vector variants) and run together, resulting in a single PASS or FAIL (for each of those nine variants plus vector variants). Building this executable involves reading over 50 MB of libm-test-*.c sources. This patch arranges for tests of each function to be run separately from the makefiles instead. There are 121 functions being tested for each (type, variant pair) (actually 126, but run as 121 from the Makefile because each of the pairs (exp10, pow10), (isfinite, finite), (lgamma, gamma), (remainder, drem), (scalbn, ldexp), shares a table of test results and so is run together), so 1089 separate tests run from the Makefile, plus 48 vector tests on x86_64 (six functions for eight vector variants). Each test only involves a libm-test-<func>.c file of no more than about 4 MB, rather than all such files taking about 50 MB. With tests run separately, test summaries will indicate which functions actually have problems (of course, those problems may just be out-of-date libm-test-ulps files if the file hasn't been updated for the architecture in question recently). All the .c files for the 1089+48 tests are generated automatically from the Makefiles. Various checked-in boilerplate .c files are removed as no longer needed. CFLAGS definitions for the different kinds of tests are generated using makefile iterators to apply target-specific variable settings. libm-have-vector-test.h is no longer needed; the list of functions to test for each vector type is now in the sysdeps Makefile. This should reduce the amount of boilerplate needed for float128 testing support; test-float128.h will still be needed, but not various .c files or Makefile CFLAGS definitions. The logic for creating dependencies on libm-test-support-*.o files should also render <https://sourceware.org/ml/libc-alpha/2017-02/msg00279.html> unnecessary.

Merge libm-compat-calls-auto and libm-compat-calls
Both libm-compat-calls and libm-compat-calls-auto list the functions that must be built for the types float, double, and long double, but not for other floating-point types that get added to libm. Besides that, the use of libm-compat-calls-ldouble-yes to select if w_lgamma_compatl and k_standardl should be built for long-double (in libm-compat-calls) has the same effect of the use of type-foreach (in libm-compat-calls-auto). This patch merges the contents of libm-compat-calls into libm-compat-calls-auto, then renames the latter to libm-compat-calls. Tested for powerpc64le, s390, and x86_64. * math/Makefile (libm-compat-calls-ldouble-yes): Merge into libm-compat-calls-auto. (libm-compat-calls): Likewise.

Move -U__LIBC_INTERNAL_MATH_INLINES to test-math-inline.h.
The libm tests of inline functions undefine __NO_MATH_INLINES (from math-CPPFLAGS) in test-math-inline.h, but __LIBC_INTERNAL_MATH_INLINES via -U options in the makefile. This is an odd inconsistency between the handling of the two macros. It also depends on the ordering (in compilation commands) of the various variables providing compiler options (which I think is why it's using CPPFLAGS-*.c instead of CFLAGS-*.c). This patch moves the undefine to test-math-inline.h, so improving consistency and eliminating the dependency on the order in which variables go in the compilation commands. The CPPFLAGS-*.c variables are renamed to CFLAGS-*.c, matching those for the non-inline libm function tests. By moving the -U option to the header file, this should ensure that ordering issues don't arise with a subsequent move of the options to these tests to target-specific CFLAGS += ... variable settings (for when tests for each function are build separately and so compilation options need setting for many more makefile targets, for which target-specific variable settings seem to be the most convenient form to generate with iterators). Tested for x86_64. * math/test-math-inline.h (__LIBC_INTERNAL_MATH_INLINES): Undefine macro. * math/Makefile (CPPFLAGS-test-ifloat.c): Rename to ... (CFLAGS-test-ifloat.c): ... this.

Build most libm-test support code once per type.
libm-test-driver.c contains various functions used in the course of libm testing, which are built as part of each test using this machinery. Currently, these functions get built for three tests for each type (e.g. test-float, test-ifloat, test-float-finite), plus the vector function tests. All these tests are huge and thus slow to build; the output of gen-libm-test.pl totals around 40 MB across all functions. To make the individual tests built from the Makefile smaller, it makes sense to split these tests up so the tests for each function are built separately (thus, three tests for each (function, type) pair, plus vector tests built only for functions that actually have vector versions). This improves parallelism and means that if tests fail, the summary of failed tests makes it more obvious where the problem might be without needing to look in the .out files to see which functions' tests failed (though architecture maintainers still need to keep libm-test-ulps up to date to avoid spurious failures of little interest). Simply including libm-test-driver.c as-is in such individual-function tests does not work because of unused static check_* functions (those functions only being used for the types of the outputs of the function under test). It also means the common code gets built over 1000 times instead of nine (plus vector tests). To avoid that issue, this patch splits out the bulk of the libm-test-driver.c code into a separate file libm-test-support.c (with a few functions made non-static). That separate file is built only once for each floating-point type (so at present three times, or twice on architectures with long double = double). Definitions needed in both libm-test-support.c and libm-test-driver.c go in libm-test-support.h (it's possible some of those are in fact only needed in one of the two files). libm-test-driver.c keeps definitions of a limited number of variables used to configure how libm-test-support.c behaves, various macros and structures needed by individual-function tests, and the main function. This move is also consistent in spirit with the move away from test-skeleton.c having all the test support code, to a small support/test-driver.c included in individual tests with most of the code built separately.

Split libm-test.inc by function.
Continuing the process of splitting up libm tests into more reasonably sized units, this patch splits libm-test.inc into 121 separate libm-test-<function>.inc files, one per array of test data. (There are 126 libm *_test functions, but five of those are for functions that are aliases for test purposes and so share arrays of test data.) In the present patch, the 121 files get processed separately by gen-libm-test.pl, each using only the auto-libm-test-out-<function> file that is relevant (/dev/null for functions not using auto-libm-test-* at all). This effectively eliminates the serialization on running gen-libm-test.pl. However, the resulting .c files still all get #included together, so compiling the limited number of libm tests using libm-test.inc may still act as a serialization point (the compilations still all have 40 MB of code to process). libm-test.inc doesn't actually have anything in it any more that needs gen-libm-test.pl processing, but is left as a .inc file that gets processed to produce a .c file, rather than being renamed, since the intent of this patch is as an intermediate step before libm-test.inc gets removed and tests get compiled separately for each function being tested. Tested for x86_64. * math/libm-test.inc: Move all tests of individual functions to libm-test-*.inc and #include libm-test-*.c files. (acos_test_data): Remove. (acos_test): Likewise.
