math: enhance the endloop condition of function handle_input_flag
In the function handle_input_flag, the end-loop condition is not correct, because when the loop variable i equals 16 (num_input_flag_types), then input_flags[16] will be out of bounds. (This issue is only relevant with invalid input files to gen-auto-libm-tests.) |

Add narrowing divide functions.
This patch adds the narrowing divide functions from TS 18661-1 to glibc's libm: fdiv, fdivl, ddivl, f32divf64, f32divf32x, f32xdivf64 for all configurations; f32divf64x, f32divf128, f64divf64x, f64divf128, f32xdivf64x, f32xdivf128, f64xdivf128 for configurations with _Float64x and _Float128; __nldbl_ddivl for ldbl-opt. The changes are mostly essentially the same as for the other narrowing functions, so the description of those generally applies to this patch as well. Tested for x86_64, x86, mips64 (all three ABIs, both hard and soft float) and powerpc, and with build-many-glibcs.py. * math/Makefile (libm-narrow-fns): Add div.

Add narrowing multiply functions.
This patch adds the narrowing multiply functions from TS 18661-1 to glibc's libm: fmul, fmull, dmull, f32mulf64, f32mulf32x, f32xmulf64 for all configurations; f32mulf64x, f32mulf128, f64mulf64x, f64mulf128, f32xmulf64x, f32xmulf128, f64xmulf128 for configurations with _Float64x and _Float128; __nldbl_dmull for ldbl-opt. The changes are mostly essentially the same as for the narrowing add functions, so the description of those generally applies to this patch as well. f32xmulf64 for i386 cannot use precision control as used for add and subtract, because that would result in double rounding for subnormal results, so that uses round-to-odd with long double intermediate result instead. The soft-fp support involves adding a new FP_TRUNC_COOKED since soft-fp multiplication uses cooked inputs and outputs. Tested for x86_64, x86, mips64 (all three ABIs, both hard and soft float) and powerpc, and with build-many-glibcs.py. * math/Makefile (libm-narrow-fns): Add mul.

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.

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.

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. |

Generate new format names in auto-libm-test-out
This converts the inclusion macro for each test to use the format specific macro. In addition, the format specifier is removed as it is applied via the LIT() macro which is itself applied when converting the auto inputs and libm-test.inc into libm-test.c. |

Use -std=gnu11 instead of -std=gnu99.
Now that GCC 4.7 or later is required to build glibc, this patch moves the build from using -std=gnu99 to -std=gnu11 (option added in 4.7). This allows use of C11 features from GCC's headers, such as new float.h macros and max_align_t. Tested for x86_64 and x86 (testsuite; installed stripped shared libraries are unchanged by the patch on x86_64, while I see some slight code reordering of no significance on x86). * Makeconfig (CFLAGS): Use -std=gnu11 instead of -std=gnu99. * Makefile ($(objpfx)c++-types-check.out): Filter out -std=gnu11 instead of -std=gnu99. * configure.ac (systemtap): Test with -std=gnu11 instead of -std=gnu99. * configure: Regenerated. * math/gen-auto-libm-tests.c: Use -std=gnu11 instead of -std=gnu99 in compilation command in comment. |

Convert 113 more function definitions to prototype style (files with assertions).
This mostly automatically-generated patch converts 113 function definitions in glibc from old-style K&R to prototype-style. Following my other recent such patches, this one deals with the case of function definitions in files that either contain assertions or where grep suggested they might contain assertions - and thus where it isn't possible to use a simple object code comparison as a sanity check on the correctness of the patch, because line numbers are changed. A few such automatically-generated changes needed to be supplemented by manual changes for the result to compile. openat64 had a prototype declaration with "..." but an old-style definition in sysdeps/unix/sysv/linux/dl-openat64.c, and "..." needed adding to the generated prototype in the definition (I've filed <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68024> for diagnosing such cases in GCC; the old state was undefined behavior not requiring a diagnostic, but one seems a good idea). In addition, as Florian has noted regparm attribute mismatches between declaration and definition are only diagnosed for prototype definitions, and five functions needed internal_function added to their definitions (in the case of __pthread_mutex_cond_lock, via the macro definition of __pthread_mutex_lock) to compile on i386. After this patch is in, remaining old-style definitions are probably most readily fixed manually before we can turn on -Wold-style-definition for all builds.

Test cpow in all rounding modes.
This patch enables testing of cpow in all rounding modes using ALL_RM_TEST. There were two reasons this was previously deferred: * MPC has complicated rounding-mode-dependent rules for the signs of exact zero real or imaginary parts in the result of mpc_pow. Annex G does not impose any such requirements and I don't think glibc should try to implement any particular logic here. This patch adds support for gen-auto-libm-tests passing the IGNORE_ZERO_INF_SIGN flag to libm-test.inc. * Error accumulations in some tests in non-default rounding modes exceed the maximum error permitted in libm-test.inc. This patch marks the problem tests with xfail-rounding. (It might be possible to reduce the accumulations a bit by using round-to-nearest when cpow calls clog, but I don't think there's much point; the implementation approach for cpow is fundamentally deficient, as discussed in the existing bug for cpow inaccuracy which can reasonably be considered to cover these less-inaccurate cases as well. It's possible that the test "cpow 2 0 10 0" will also need xfail-rounding on some platforms.) Tested x86_64 and x86 and ulps updated accordingly. * math/gen-auto-libm-tests.c: Document use of ignore-zero-inf-sign. (input_flag_type): Add value flag_ignore_zero_inf_sign.

Relax gen-auto-libm-tests may-underflow rules, test log1p in all rounding modes.
gen-auto-libm-tests presently allows but does not require underflow exceptions for results with magnitude in the range (greatest subnormal, least normal]. In some cases, the magnitude of the exact result is very slightly above the least normal, but rounding in the implementation results in it effectively computing an infinite-precision result that is slightly below the least normal, so raising an underflow exception. This is in accordance with the documented accuracy goals, but results in testsuite failures. This patch changes the logic to allow underflows when the mathematical result is up to 0.5ulp above the least normal (so in any case where the round-to-nearest result is the least normal). Ideally underflows in all these cases would be accepted only when an underflow with the actual result is consistent with the rounding mode (in FE_TOWARDZERO mode, a return value of the least normal implies that the infinite-precision result did not underflow so there should be no underflow exception, for example), so as to match the documented goals more precisely - whereas at present the tests for exceptions are completely independent of the tests of the returned values. (The same applies to overflow exceptions as well - they too should be checked for consistency with the result, as in FE_TOWARDZERO mode a result 1ulp below the largest finite value should be inconsistent with an overflow exception and cause a failure with overflow rather than simply being considered a 1ulp error when overflow is expected.) But the present patch at least deals with the cases causing spurious failures so that (a) certain existing tests no longer need to be marked as having spurious exceptions (such markings in auto-libm-test-in end up applying to more cases than just those they are needed for) and (b) log1p can be tested in all rounding modes without introducing more such failures. This patch duly moves tests of log1p to ALL_RM_TEST. Tested x86_64 and x86 and ulps updated accordingly.

Adjust how gen-auto-libm-tests handles before-rounding/after-rounding cases.
This patch changes gen-auto-libm-tests so that, when generating test results that depend on whether the architecture has before-rounding or after-rounding tininess detection, the :before-rounding or :after-rounding conditions go on the exception / errno flags generated, rather than generating two separate lines in auto-libm-test-out for e.g. flt-32:before-rounding and flt-32:after-rounding. The rationale for this is as follows. It would be desirable for testing a libm function in all rounding modes to require just one function and array in libm-test.inc, not four (or five), with the array of test data including expected results for all rounding modes rather than separate arrays for each rounding mode that also need to repeat all the test inputs. For gen-libm-test.pl to generate data for such an array from auto-libm-test-out, it would be helpful if each (format, test input) pair has exactly four lines in auto-libm-test-out, one for each rounding mode, rather than some rounding modes having just one line and some having two because the exceptions depend on tininess detection. Tested x86_64 and x86. * math/gen-auto-libm-tests.c: Update comment on output format. (output_for_one_input_case): Generate before-rounding and after-rounding information as conditions on output flags not floating-point format. * math/auto-libm-test-out: Regenerated. * math/gen-libm-test.pl (cond_value): New function. (or_cond_value): Use cond_value. (generate_testfile): Handle conditional exceptions. |

Move tests of fma from libm-test.inc to auto-libm-test-in.
This patch moves tests of fma to auto-libm-test-in, adding the required support to gen-auto-libm-tests. Because fma can have exact zero results depending on the rounding mode, results of fma cannot always be determined from a single value computed in higher precision with a sticky bit. Thus, this patch adds support for recomputing results with the original MPFR/MPC function in the case where an exact zero is involved. (This also affects some results for cpow; when we start testing cpow in all rounding modes, I think it will be most appropriate to make those tests use IGNORE_ZERO_INF_SIGN, since ISO C does not attempt to determine signs of zero results, or special caes in general, for cpow, and I think signs of zero for cpow are beyond the scope of glibc's accuracy goals.) Simply treating the existing test inputs for fma like those for other functions (i.e., as representing the given value rounded up or down to any of the supported floating-point formats) increases the size of auto-libm-test-out by about 16MB (i.e., about half the file is fma test data). While rounded versions of tests are perfectly reasonable test inputs for fma, in this case having them seems excessive, so this patch allows functions to specify in gen-auto-libm-tests that the given test inputs are only to be interpreted exactly, not as corresponding to values rounded up and down. This reduces the size of the generated test data for fma to a more reasonable 2MB. A consequence of this patch is that fma is now tested for correct presence or absence of "inexact" exceptions, where previously this wasn't tested because I didn't want to try to add that test coverage manually to all the existing tests. As far as I know, the existing fma implementations are already correct in this regard. This patch provides the first cases where the gen-auto-libm-tests support for distinguishing before-rounding/after-rounding underflow actually produces separate entries in auto-libm-test-out (for functions without exactly determined results, the affected cases are all considered underflow-optional, so this only affects functions like fma with exactly determined results). I didn't see any signs of problems with this logic in the output. Tested x86_64 and x86. * math/auto-libm-test-in: Add tests of fma. * math/auto-libm-test-out: Regenerated. * math/libm-test.inc (fma_test_data): Use AUTO_TESTS_fff_f.

Fix gen-auto-libm-tests sticky bit setting for negative results.
gen-auto-libm-tests has a bug in the logic for setting a sticky bit based on the ternary value from MPFR: it is correct for positive results, but for negative results mpz_setbit acts as if a two's complement representation is used, whereas the low bit needs setting based on the sign-magnitude representation GMP actually uses. (This showed up in converting fma tests to use auto-libm-test-in / gen-auto-libm-tests.) This patch fixes the problem by negating the mpz_t value to set its low bit. There are lots of changes to auto-libm-test-out (mainly 1ulp fixes to ldbl-128 expected results), but only a few ulps updates are needed on x86 / x86_64. In one case, a corrected expectation showed up a spurious underflow exception where the correct result is slightly outside the underflowing range. Tested x86_64 and x86 and ulps updated accordingly. * math/gen-auto-libm-tests.c (adjust_real): Ensure integers are non-negative before setting low bit. * math/auto-libm-test-in: Mark one asin test possibly having spurious underflow. * math/auto-libm-test-out: Regenerated. * sysdeps/i386/fpu/libm-test-ulps: Update. * sysdeps/x86_64/fpu/libm-test-ulps: Likewise. |

Move various TEST_c_c tests from libm-test.inc to auto-libm-test-inc.
This patch moves tests of ccos, ccosh, cexp, clog, csqrt, ctan and ctanh to auto-libm-test-in, adding the required support to gen-auto-libm-tests. Other TEST_c_c functions aren't moved for now (although the relevant table entries are put in gen-auto-libm-tests for it to know how to handle them): clog10 because of a known MPC bug causing it to hang for at least some pure imaginary inputs (fixed in SVN, but I'd rather not rely on unreleased versions of MPFR or MPC even if relying on very recent releases); the inverse trig and hyperbolic functions because of known slowness in special cases; and csin / csinh because of observed slowness that I need to investigate and report to the MPC maintainers. Slowness can be bypassed by moving to incremental generation (only for new / changed tests) rather than regenerating the whole of auto-libm-test-out every time, but that needs implementing. (This patch takes the time for running gen-auto-libm-tests from about one second to seven, on my system, which I think is reasonable. The slow functions would make it take several minutes at least, which seems unreasonable.)
