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. |

Suppress internal declarations for most of the testsuite.
This patch adds a new build module called 'testsuite'.
IS_IN (testsuite) implies _ISOMAC, as do IS_IN_build and __cplusplus
(which means several ad-hoc tests for __cplusplus can go away).
libc-symbols.h now suppresses almost all of *itself* when _ISOMAC is
defined; in particular, _ISOMAC mode does not get config.h
automatically anymore.
There are still quite a few tests that need to see internal gunk of
one variety or another. For them, we now have 'tests-internal' and
'test-internal-extras'; files in this category will still be compiled
with MODULE_NAME=nonlib, and everything proceeds as it always has.
The bulk of this patch is moving tests from 'tests' to
'tests-internal'. There is also 'tests-static-internal', which has
the same effect on files in 'tests-static', and 'modules-names-tests',
which has the *inverse* effect on files in 'modules-names' (it's
inverted because most of the things in modules-names are *not* tests).
For both of these, the file must appear in *both* the new variable and
the old one.
There is also now a special case for when libc-symbols.h is included
without MODULE_NAME being defined at all. (This happens during the
creation of libc-modules.h, and also when preprocessing Versions
files.) When this happens, IS_IN is set to be always false and
_ISOMAC is *not* defined, which was the status quo, but now it's
explicit.
The remaining changes to C source files in this patch seemed likely to
cause problems in the absence of the main change. They should be
relatively self-explanatory. In a few cases I duplicated a definition
from an internal header rather than move the test to tests-internal;
this was a judgement call each time and I'm happy to change those
however reviewers feel is more appropriate.
* Makerules: New subdir configuration variables 'tests-internal'
and 'test-internal-extras'. Test files in these categories will
still be compiled with MODULE_NAME=nonlib. Test files in the
existing categories (tests, xtests, test-srcs, test-extras) are
now compiled with MODULE_NAME=testsuite.
New subdir configuration variable 'modules-names-tests'. Files
which are in both 'modules-names' and 'modules-names-tests' will
be compiled with MODULE_NAME=testsuite instead of
MODULE_NAME=extramodules.
(gen-as-const-headers): Move to tests-internal.
(do-tests-clean, common-mostlyclean): Support tests-internal.
* Makeconfig (built-modules): Add testsuite.
* Makefile: Change libof-check-installed-headers-c and
libof-check-installed-headers-cxx to 'testsuite'.
* Rules: Likewise. Support tests-internal.
* benchtests/strcoll-inputs/filelist#en_US.UTF-8:
Remove extra-modules.mk.
* config.h.in: Don't check for __OPTIMIZE__ or __FAST_MATH__ here.
* include/libc-symbols.h: Move definitions of _GNU_SOURCE,
PASTE_NAME, PASTE_NAME1, IN_MODULE, IS_IN, and IS_IN_LIB to the
very top of the file and rationalize their order.
If MODULE_NAME is not defined at all, define IS_IN to always be
false, and don't define _ISOMAC.
If any of IS_IN (testsuite), IS_IN_build, or __cplusplus are
true, define _ISOMAC and suppress everything else in this file,
starting with the inclusion of config.h.
Do check for inappropriate definitions of __OPTIMIZE__ and
__FAST_MATH__ here, but only if _ISOMAC is not defined.
Correct some out-of-date commentary.
* include/math.h: If _ISOMAC is defined, undefine NO_LONG_DOUBLE
and _Mlong_double_ before including math.h.
* include/string.h: If _ISOMAC is defined, don't expose
_STRING_ARCH_unaligned. Move a comment to a more appropriate
location.
* include/errno.h, include/stdio.h, include/stdlib.h, include/string.h
* include/time.h, include/unistd.h, include/wchar.h: No need to
check __cplusplus nor use __BEGIN_DECLS/__END_DECLS.
* misc/sys/cdefs.h (__NTHNL): New macro.
* sysdeps/m68k/m680x0/fpu/bits/mathinline.h
(__m81_defun): Use __NTHNL to avoid errors with GCC 6.
* elf/tst-env-setuid-tunables.c: Include config.h with _LIBC
defined, for HAVE_TUNABLES.
* inet/tst-checks-posix.c: No need to define _ISOMAC.
* intl/tst-gettext2.c: Provide own definition of N_.
* math/test-signgam-finite-c99.c: No need to define _ISOMAC.

* stdlib/tst-strtod5.c: Convert to test-driver and add copyright notice.
Split tests of __strtod_internal to...
* stdlib/tst-strtod5i.c: ...this new file.
* string/test-string.h: Include stdint.h. Duplicate definition of
inhibit_loop_to_libcall here (from libc-symbols.h).
* string/test-strstr.c: Provide dummy definition of
libc_hidden_builtin_def when including strstr.c.
* sysdeps/ia64/fpu/libm-symbols.h: Suppress entire file in _ISOMAC
mode; no need to test __STRICT_ANSI__ nor __cplusplus as well.
* sysdeps/x86_64/fpu/math-tests-arch.h: Include cpu-features.h.
Don't include init-arch.h.
* sysdeps/x86_64/multiarch/test-multiarch.h: Include cpu-features.h.
Don't include init-arch.h.

Macroize inclusion of math-finite.h
This patch macroizes the declarations in math/bits/math-finite.h similarly to what math/bits/mathcalls.h does. For each floating-point type, the file is included once in math/math.h.

Remove C++ namespace handling from glibc headers.
glibc headers include some code (not particularly consistent or systematic) to put various declarations in C++ namespaces std and __c99, if _GLIBCPP_USE_NAMESPACES is defined. As noted in <https://gcc.gnu.org/ml/libstdc++/2017-03/msg00025.html>, this macro was removed from libstdc++ in 2000. I don't expect compilation with such old versions of libstdc++ to work with current glibc headers anyway (whereas old *binaries* are expected to stay working with current glibc); this patch (which should be a no-op with any libstdc++ version postdating that removal) removes all this code from the glibc headers. The begin-end-check.pl test, whose comments say it is about checking these namespace macro calls, is also removed. The code in that test would have covered __BEGIN_DECLS / __END_DECLS as well, but if those weren't properly matched it would show up with the check-installed-headers-cxx tests, so I don't think there is an actual use for keeping begin-end-check.pl with the namespace code removed. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). * misc/sys/cdefs.h (__BEGIN_NAMESPACE_STD): Remove macro.

Improve float range reduction accuracy near pi/2 (bug 21094).
Bug 21094 reports 3ulp errors of cosf and tanf for certain arguments near pi/2 arising from the use of an insufficiently accurate range reduction. (To be clear, this is a quality-of-implementation issue relating to the apparent intent of those particular cosf and tanf implementations; 3ulp is within the general glibc accuracy goals, so not inherently a bug.) This patch fixes that error by making a wider range of cases use the existing more accurate range reduction for arguments close to pi/2. The wider range of values is still narrow enough for the "z -= pio2_2;" in the more accurate case to be exact, as the code expects. Tested for x86_64, x86 and mips64; no ulps updates needed (but at least on mips64, the larger ulps were seen if the tests were added without the substantive fix). [BZ #21094] * sysdeps/ieee754/flt-32/e_rem_pio2f.c (__ieee754_rem_pio2f): Use 24+24+24-bit pi for wider range of values around pi/2. * math/auto-libm-test-in: Add more tests of cos and tan. * math/auto-libm-test-out-cos: Regenerated. * math/auto-libm-test-out-tan: Likewise. |

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. |

Update auto-libm-test-out for catan / catanh.
I've used gmp 6.1.2, mpfr 3.1.5 and upstream mpc with fix in mpc_atan (https://scm.gforge.inria.fr/anonscm/gitweb?p=mpc/mpc.git;a=commit;h=958aac9b15a659d6fb5edcb11778123f8a35b14f) to build gen-auto-libm-tests and regenerated catan / catanh out files. Regenerated ULPs for s390 from scratch. Now the catan / catanh tests are passing. ChangeLog: * math/auto-libm-test-out-catan: Regenerated. * math/auto-libm-test-out-catanh: Likewise. * sysdeps/s390/fpu/libm-test-ulps: Likewise. |

Miscellaneous low-risk changes preparing for _ISOMAC testsuite.
These are a grab bag of changes where the testsuite was using internal symbols of some variety, but this was straightforward to fix, and the fixed code should work with or without the change to compile the testsuite under _ISOMAC. Four of these are just more #include adjustments, but I want to highlight sysdeps/powerpc/fpu/tst-setcontext-fpscr.c, which appears to have been written before the advent of sys/auxv.h. I think a big chunk of this file could be replaced by a simple call to getauxval, but I'll let someone who actually has a powerpc machine to test on do that. dlfcn/tst-dladdr.c was including ldsodefs.h just so it could use DL_LOOKUP_ADDRESS to print an additional diagnostic; as requested by Carlos, I have removed this. math/test-misc.c was using #ifndef NO_LONG_DOUBLE, which is an internal configuration macro, to decide whether to do certain tests involving 'long double'. I changed the test to #if LDBL_MANT_DIG > DBL_MANT_DIG instead, which uses only public float.h macros and is equivalent on all supported platforms. (Note that NO_LONG_DOUBLE doesn't mean 'the compiler doesn't support long double', it means 'long double is the same as double'.) tst-writev.c has a configuration macro 'ARTIFICIAL_LIMIT' that the Makefiles are expected to define, and sysdeps/unix/sysv/linux/Makefile was using the internal __getpagesize in the definition; changed to sysconf(_SC_PAGESIZE) which is the POSIX equivalent. ia64-linux doesn't supply 'clone', only '__clone2', which is not defined in the public headers(!) All the other clone tests have local extern declarations of __clone2, but tst-clone.c doesn't; it was getting away with this because include/sched.h does declare __clone2. * nss/tst-cancel-getpwuid_r.c: Include nss.h. * string/strcasestr.c: No need to include config.h. * sysdeps/powerpc/fpu/tst-setcontext-fpscr.c: Include sys/auxv.h. Don't include sysdep.h. * sysdeps/powerpc/tst-set_ppr.c: Don't include dl-procinfo.h. * dlfcn/tst-dladdr.c: Don't include ldsodefs.h. Don't use DL_LOOKUP_ADDRESS. * math/test-misc.c: Instead of testing NO_LONG_DOUBLE, test whether LDBL_MANT_DIG is greater than DBL_MANT_DIG. * sysdeps/unix/sysv/linux/Makefile (CFLAGS-tst-writev.c): Use sysconf (_SC_PAGESIZE) instead of __getpagesize in definition of ARTIFICIAL_LIMIT. * sysdeps/unix/sysv/linux/tst-clone.c [__ia64__]: Add extern declaration of __clone2. |

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.

Add new templates for IEEE wrappers
Several wrappers for IEEE functions use _LIB_VERSION / matherr / __kernel_standard functionality, which we want to obsolete. New wrappers, such as for float128, must not use this functionality.

Move INIT_ARCH_EXT call from libm-test-support to libm-test-driver.
libmvec tests involve calling INIT_ARCH_EXT during initialization then CHECK_ARCH_EXT before testing each function to see if the processor being used for testing supports the required instruction set extensions. After my refactoring of libm-test infrastructure, the INIT_ARCH_EXT call is in libm-test-support.c, built only once per floating-point type. Now, in fact all definitions of this macro are empty, but given that the definitions in sysdeps/x86_64/fpu/math-tests-arch.h are conditional on REQUIRE_* macros defined in particular vector tests, it seems more correct for the INIT_ARCH_EXT call to go instead in libm-test-driver.c which gets built separately with those REQUIRE_* macros properly defined. This patch moves the call there. Tested for x86_64 and x86. * math/libm-test-support.h: Do not include <math-tests-arch.h> here. * math/libm-test-support.c (libm_test_init): Do not call INIT_ARCH_EXT here. * math/libm-test-driver.c: Include <math-tests-arch.h>.

Move more csin, csinh tests to auto-libm-test-in.
When I moved tests of csin and csinh to auto-libm-test-in, I didn't move a few tests for which gen-auto-libm-tests was very slow because of MPC slowness on certain inputs. Now that auto-libm-test-out has been split up, such slowness only affects regenerating the test expectations for the individual functions in question, rather than any addition of tests for any function to auto-libm-test-in. Thus, I no longer consider it a problem to have these inputs in auto-libm-test-in, and this patch moves them there. This results in test generation for csin and csinh taking 5m43s (for each of csin and csinh) on my system, while other functions are unaffected. I expect the test generation to be much faster in MPC 1.1 (the relevant performance improvements went in MPC mainline in Dec 2013, but there hasn't been a release from mainline since then). Tested for x86_64 and x86. * math/auto-libm-test-in: Add more tests of csin and csinh. * math/auto-libm-test-out-csin: Regenerated. * math/auto-libm-test-out-csinh: Likewise. * math/libm-test-csin.inc (csin_test_data): Remove tests moved to auto-libm-test-in. * math/libm-test-csinh.inc (csinh_test_data): Likewise. |

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.

Clean up libm vector tests exception test disabling.
The libm vector tests disable tests of exception raising via defining macros EXCEPTION_TESTS_float and EXCEPTION_TESTS_double to 0 in the headers for individual vector lengths. As EXCEPTION_TESTS is used in code in libm-test-driver.c that is otherwise ready to be built only once per type, this is not a good idea; it's better to define TEST_EXCEPTIONS appropriately so that flag_test_exceptions then gets initialized appropriately. Furthermore, it's better to do this just once, in test-math-vector.h, since there is no actual dependence on the vector length or type. This patch duly makes that change.

Fix powf inaccuracy (bug 21112).
Bug 21112 reports a case where powf is substantially inaccurate. This results from a multiplication where cp_h*p_h is required to be exact, and p_h is masked to have only 12 leading nonzero bits in its mantissa, but the value of cp_h has the 13th bit nonzero, leading to inexact multiplication results in some cases that can result in large errors in the final result of powf. This patch fixes this by using a value of cp_h correctly rounded to nearest to 12 bits, with a corresponding updated value of cp_l. Tested for x86_64 and x86. [BZ #21112] * sysdeps/ieee754/flt-32/e_powf.c (cp_h): Use value with trailing 12 bits zero.

Refactor some code in libm-test-driver.c.
Splitting libm tests by function will mean about a thousand such tests built separately instead of the present nine (plus vector variants). When this is done, it's desirable to avoid needing to build all the test infrastructure so many times. Also, simply including libm-test-driver.c as-is into per-function tests doesn't actually work, because the various check_* functions are not used by all tests and so generate errors for unused static functions. Although some pieces of infrastructure depend on the type being tested while others don't, building once per type seems the simplest approach. This patch makes changes to libm-test-driver.c in preparation for that. Various cases where functions directly use macros such as TEST_ERRNO (that may vary depending on things other than the type under test) are changed to use variables initialized using those macros, while most of the code in main is moved out to functions libm_test_init and libm_test_fini. The idea is that all the functions in libm-test-driver.c will be moved out in a subsequent patch to be built once per type (and be no longer static when they are used from per-function tests), while libm-test-driver.c remains containing definitions of various variables (no longer static, of course, because they'll be used in the per-type code) and the main function. Declarations / macros relevant to both the once-per-type code and the per-function tests will go in a shared header. Tested for x86_64. * math/libm-test-driver.c (flag_test_errno): New variable. (flag_test_exceptions): Likewise. (flag_test_finite): Likewise. (flag_test_inline): Likewise. (flag_test_mathvec): Likewise. (test_msg): Likewise. (ulp_idx): Likewise. (qtype_str): Likewise. (ULP_IDX): Remove macro. (QTYPE_STR): Likewise. (find_ulps): Use ulp_idx not ULP_IDX.

(enable_test): Use flag_test_inline, flag_test_finite and flag_test_mathvec instead of TEST_INLINE, TEST_FINITE and TEST_MATHVEC. (libm_test_init): New function. Factored out of main.

Move libm-test TEST_MSG definitions to libm-test-driver.c.
Various files using the libm-test infrastructure define a TEST_MSG macro with an informal description of the tests being run. This patch moves this macro to libm-test-driver.c (the definition depending on other macros already defined), so files specific to (type, choice of whether to test inline functions or finite-math-only functions, vector length) no longer need to define it. This is in preparation for replacing files such as test-float.c with per-function test-float-<func>.c etc. automatically generated in the build directory when tests are run. Tested for x86_64. * math/libm-test-driver.c (STRX): New macro. (STR): Likewise. (STR_FLOAT): Likewise. (STR_VEC_LEN): Likewise. (TEST_MSG): Likewise. Define here instead of expecting to be defined by including file. * math/test-double-finite.c (TEST_MSG): Remove macro. * math/test-double-vlen2.h (TEST_MSG): Likewise. * math/test-double-vlen4.h (TEST_MSG): Likewise. * math/test-double-vlen8.h (TEST_MSG): Likewise. * math/test-double.c (TEST_MSG): Likewise. * math/test-float-finite.c (TEST_MSG): Likewise. * math/test-float-vlen16.h (TEST_MSG): Likewise. * math/test-float-vlen4.h (TEST_MSG): Likewise. * math/test-float-vlen8.h (TEST_MSG): Likewise. * math/test-float.c (TEST_MSG): Likewise. * math/test-idouble.c (TEST_MSG): Likewise. * math/test-ifloat.c (TEST_MSG): Likewise. * math/test-ildouble.c (TEST_MSG): Likewise. * math/test-ldouble-finite.c (TEST_MSG): Likewise. * math/test-ldouble.c (TEST_MSG): Likewise. |

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.

Split auto-libm-test-out by function.
math/auto-libm-test-out is, at over 30 MB, by far the largest file in the glibc source tree. This patch splits it by function, so reducing it to auto-libm-test-out-<func> files that are all under 5 MB in size. This is preliminary to splitting up libm-test.inc as well so that each function's tests can also be processed separately by gen-libm-test.pl. As a preliminary patch it doesn't actually implement that step; rather, all the separate files get concatenated by the Makefile to produce the monolithic auto-libm-test-out file again as an input to gen-libm-test.pl. (The concatentation is identical to the file in the source tree before this patch.) Even this preliminary step, however, is of use independent of splitting up libm-test.inc: some tests for csin and csinh have not been moved to auto-libm-test-in because they result in auto-libm-test-out generation taking several minutes rather than a few seconds (all released MPC versions are very slow for certain sin / sinh inputs; there are some old improvements in MPC mainline which should eventually become MPC 1.1, but the complex inverse trig and hyperbolic functions are slow even in MPC mainline and have yet to be moved to auto-libm-test-in at all), and it seems much more reasonable to add such inputs to auto-libm-test-in when it will only slow down regeneration for particular functions than when it will slow down regeneration globally. gen-auto-libm-tests still parses the whole input file, but only generates output for the requested function. This ensures bad syntax in the file is always detected, and parsing the whole file is quick; it's output generation that is comparatively slow for some functions.

Eliminate libm-test.stmp.
math/Makefile uses libm-test.stmp to handle dependencies involving multiple generated files all generated by a single sequence of commands in a single Makefile rule. Having separated the libm-test-ulps.h and libm-test.c generation into separate runs of gen-libm-test.pl, there is now no need for a single rule to generate multiple target files; each of the three target files involved can be generated by a separate Makefile rule, meaning normal dependencies on the individual files can be used and so libm-test.stmp is not needed at all. This patch does just that, eliminating the .stmp file, in further preparation for when there are many separate libm-test-<func>.c files generated from libm-test-<func>.inc and the dependencies are on just the relevant .c file in each case. Tested for x86_64. * math/Makefile (generated): Do not include libm-test.stmp. ($(addprefix $(objpfx), $(libm-tests-generated))): Do not depend on $(objpfx)libm-test.stmp.

Rework gen-libm-test.pl input/output handling.
This patch reworks how input and output files are specified for gen-libm-test.pl. Previously, the script had names of various inputs and outputs hardcoded, with a -o option to specify an output directory. This patch replaces this with all inputs and outputs being specified explicitly as the arguments of options passed to the script. Outputs are only generated if the relevant option is passed, and only the processing required for the indicated outputs is done. The Makefile is made to pass options for generating libm-test-ulps.h in a separate invocation of gen-libm-test.pl from that generating libm-test.c.

Move non-function-specific parts of libm-test.inc to separate file.
libm-test.inc contains both test infrastructure and tests of individual functions. This patch moves the infrastructure to a separate file libm-test-driver.c. This is in preparation for splitting the tests of individual functions into separate source files, which will be processed individually by gen-libm-test.pl (so e.g. libm-test-acos.inc and auto-libm-test-out-acos will be processed by gen-libm-test.pl to produce libm-test-acos.c, and files such as test-double-acos.c will be generated by the Makefile to include appropriate headers, libm-test-driver.c and libm-test-acos.c so tests of each function get run separately). It is no doubt possible to split things up further, so that functions not depending on the type being tested only get compiled once and most of those depending on the type being tested get compiled once per type (rather than separately for variants such as inline / no-inline, and separately for each function being tested after that split), but this rearrangement as-is seems a useful incremental step towards splitting these tests by function. * math/libm-test-driver.c: New file.

Remove libm-test.inc comment listing functions tested and not tested.
math/libm-test.inc has a comment listing the functions tested and not tested. The list of functions tested duplicates what is immediately obvious from the rest of the file and adds another place to update when adding a function. I've put the information about functions not tested on the wiki todo list; this patch removes that comment, in preparation for splitting tests of each function into separate .inc files with common code staying in a separate .c file. Tested for x86_64. * math/libm-test.inc: Remove comment listing functions tested and not tested. |

Remove before-compile setting in math/Makefile.
In <https://sourceware.org/ml/libc-alpha/2015-12/msg00543.html>, Florian noted highly parallel builds being slowed down by gen-libm-test.pl running during the build, when it should only run for testing, not for building glibc itself. This is a consequence of libm-test.c being listed in before-compile. That listing in before-compile arose from the error reported in <https://sourceware.org/ml/libc-hacker/1999-10/msg00054.html> when building dependencies: at that time, dependencies were generated separation from compilation, so if a source file included a generated file it wasn't enough for the dependencies for the .o file to be correct, the generated file needed to be listed in before-compile. Since <https://sourceware.org/ml/libc-hacker/2003-05/msg00001.html>, dependencies are generated as a side-effect of compilation. This means that having the right dependencies for the .o files for the tests fully suffices to ensure that libm-test.c is generated by the time it's needed; no entry in before-compile is needed. And we indeed have such a dependency for all the tests using libm-test.c: $(addprefix $(objpfx), $(libm-tests.o)): $(objpfx)libm-test.stmp Thus, the before-compile definition is unnecessary, and this patch removes it. (This may of course move serialization from the glibc build to glibc testing, but I intend to split up libm-test.inc so that tests for each (floating-point type, libm function) pair are built and run separately, which should reduce that serialization.) Tested for x86_64. * math/Makefile (before-compile): Remove. |

Make fallback fegetexceptflag work with generic fetestexceptflag.
The generic implementation of fetestexceptflag does:
int
fetestexceptflag (const fexcept_t *flagp, int excepts)
{
/* Most versions of fegetexceptflag store exceptions in a form such
that this works. */
return *flagp & excepts & FE_ALL_EXCEPT;
}
In the case where FE_ALL_EXCEPT is nonzero but exceptions may not be
supported at runtime, this only works if fegetexceptflag cleared all
the bits of FE_ALL_EXCEPT in *flagp; otherwise it accesses
uninitialized data. This showed up as a failure of
math/test-fetestexceptflag for MIPS o32 soft-float. This patch makes
the fallback fegetexceptflag store 0 (fexcept_t is an integer type
everywhere) so that this works. (No bug report in Bugzilla because
this wasn't user-visible - at least, without using tools to detect
uninitialized memory use at runtime - without fetestexceptflag, which
is new in 2.25.)
Tested for MIPS o32 soft-float.
* math/fgetexcptflg.c (__fegetexceptflag): Store 0 in fexcept_t
object.

XFAIL libm-test.inc tests as needed for ibm128.
This patch arranges for various libm-test.inc tests to be XFAILed for ibm128-libgcc in non-default rounding modes. The tests are marked with XFAIL_ROUNDING_IBM128_LIBGCC and gen-libm-test.pl is made to transform that to XFAIL_IBM128_LIBGCC or 0 depending on the rounding mode. This should allow test-ldouble, test-ildouble and test-ldouble-finite to pass with unmodified libgcc, given an ulps regeneration. (The case of patched libgcc was already clean up to ulps and possibly hypot cases very close to the overflow threshold that may need more XFAILing; patched libgcc, which should work with TEST_COND_ibm128_libgcc defined to 0 to disable all these XFAILs, does need slightly different ulps from unpatched.) Note that soft-float powerpc will still fail because of <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64811> resulting in spurious "invalid" exceptions in the libgcc code (for hard float, <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58684> hides that bug). Tested for powerpc. * math/libm-test.inc (XFAIL_IBM128_LIBGCC): New macro. (fdim_test_data): Use XFAIL_ROUNDING_IBM128_LIBGCC for some tests. (fma_test_data): Likewise. (hypot_test_data): Likewise.

Improve libm-test XFAILing for ibm128-libgcc.
This patch further improves XFAILing for ibm128-libgcc of tests in auto-libm-test-*. The bulk of the cases needing XFAILing are xfail-rounding:ibm128-libgcc used for inputs where (possibly after rounding the inputs to another floating-point type) the result overflows (and the result in non-default rounding modes may be wildly wrong with unpatched libgcc) or underflows near 0 (and the result in non-default rounding modes may end up having the wrong sign). This patch makes gen-auto-libm-tests detect such cases and apply xfail-rounding:ibm128-libgcc automatically to them, so most of the manual XFAILs in auto-libm-test-in are no longer needed (some are still needed if e.g. the result is very close to overflow, resulting in an internal overflow in libgcc in some rounding modes). A few manual XFAILs are added for cases not covered by this gen-auto-libm-tests change, and a few existing such XFAILs are left in. Tested for powerpc. * math/gen-auto-libm-tests.c (output_for_one_input_case): Apply xfail-rounding:ibm128-libgcc automatically to tests overflowing and those that can underflow to zero. * math/auto-libm-test-in: Remove most XFAILs for ibm128-libgcc and add others. * math/auto-libm-test-out: Regenerated. |

Make fallback fesetexceptflag always succeed (bug 21028).
The fallback implementation of fesetexceptflag currently fails if any exceptions are specified. It should always succeed, because the exception state is always that all exceptions (if any are defined in <fenv.h> but not supported in this configuration) are always clear, just as fallback fetestexcept always succeeds and fallback fesetenv always succeeds unless asked to set FE_NOMASK_ENV. This patch fixes it accordingly. Together with the patch to test-fexcept.c to allow feraiseexcept to fail in another place, this stops that test from failing for MIPS soft-float. Tested for mips64 soft-float. [BZ #21028] * math/fsetexcptflg.c (__fesetexceptflag): Always return 0. * math/test-fexcept.c (test_set): Allow failure of feraiseexcept if EXCEPTION_TESTS returns false. |

Update libm-test XFAILs for ibm128 format.
This patch cleans up and updates the libm-test XFAILs for the ibm128 format. More of them are changed to use a new ibm128-libgcc conditional, to reflect that they are not in fact needed if you've patched libgcc to fix the known issues (at substantial performance cost). Many additional XFAILs are added for tests that fail with unpatched libgcc (most but not all of them xfail-rounding). Note that further such fixes will be needed for test-ldouble actually to pass with default libgcc (in particular, XFAILs for pow tests and for various affected tests directly embedded in libm-test.inc). With patched libgcc, there may be a few XFAILs needed but the results are already substantially clean apart from a few ulps differences. Tested for powerpc. * math/libm-test.inc (TEST_COND_ibm128_libgcc): New macro. (init_max_error) [TEST_COND_ibm128]: Increase maximum error allowed to 16 ulps. * math/auto-libm-test-in: Change most XFAILs for ibm128 to use ibm128-libgcc. XFAIL more tests for ibm128-libgcc. * math/auto-libm-test-out: Regenerated. |
