* Remove shlib-versions ABI names support.Joseph Myers2014-06-271-1/+0
| | | | | | | | | | | | | | | | | | | | shlib-versions files can contain ABI lines that map triplets to a canonical ABI name. This name was once used for various purposes where test baseline files for different ABIs went in a single directory; now these purposes use sysdeps files, generation of headers which have per-ABI variants uses abi-variants and related Makefile variables and the shlib-versions ABI names are unused. This patch duly removes those lines and associated build system support for them. Tested for x86_64 (both a full testsuite run and confirming the installed shared libraries are unchanged by the patch). * Makeconfig ($(common-objpfx)soversions.mk): Do not generate abi-name definition. * scripts/soversions.awk: Do not handle or generate ABI lines. * shlib-versions: Remove ABI entries. * sysdeps/powerpc/nofpu/shlib-versions: Remove file. * sysdeps/x86_64/x32/shlib-versions: Remove ABI entry.
* Don't include individual test ulps in libm-test-ulps.Joseph Myers2014-03-051-12926/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As recently discussed <https://sourceware.org/ml/libc-alpha/2014-02/msg00670.html>, it doesn't seem particularly useful for libm-test-ulps files to contain huge amounts of data on ulps for individual tests; just the global maximum observed ulps for each function, together with the verification of exceptions, errno and special results such as infinities and NaNs for each test, suffices to verify that a function's behavior on the given test inputs is within the expected accuracy. Removing this data reduces source tree churn caused by updates to these files when libm tests are added, and reduces the frequency with which testsuite additions actually need libm-test-ulps changes at all. Accordingly, this patch removes that data, so that individual tests get checked against the global bounds for the given function and only generate an error if those are exceeded. Tested x86_64 (including verifying that if an ulps value is artificially reduced, the tests do indeed fail as they should and "make regen-ulps" generates the expected changes). * math/libm-test.inc (struct ulp_data): Don't refer to ulps for individual tests in comment.

* Fix soft-float ldbl-128ibm atan2l signs of zero results (bug 16390).Joseph Myers2014-01-031-0/+1
| | | | | | | | | | | This patch fixes bug 16390, incorrect signs of zero results from ldbl-128ibm atan2l, soft-float only. The problem is a longstanding GCC bug with fabsl not being correct for signed zero for soft float, and the fix is using -fno-builtin-fabsl as a workaround, as already done for various other source files. Tested powerpc-nofpu. * sysdeps/powerpc/nofpu/Makefile [$(subdir) = math] (CFLAGS-e_atan2l.c): Use -fno-builtin-fabsl.

* Don't make soft-fp symbols compat symbols for powerpc-nofpu.Joseph Myers2013-12-191-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sysdeps/powerpc/powerpc32/libgcc-compat.S makes certain symbols that glibc once accidentally reexported from libgcc into compat symbols. Where the exports were purely accidental, this is the right thing to do. However, for powerpc-nofpu the soft-fp symbols are deliberately exported from libc, given public versions in sysdeps/powerpc/nofpu/Versions and used by libm in preference to the libgcc versions that do not support the software exceptions and rounding modes. The libc versions should also be usable by user programs, though normally libgcc gets linked in first (meaning, effectively, that the <fenv.h> functions are broken as regards their expected effects on user arithmetic). A longstanding todo item is to remove the functions in question from libgcc (when built with recent enough glibc) - that is, remove them from static libgcc and make them compat symbols in shared libgcc - so that this works properly (this is one of the items mentioned at <http://gcc.gnu.org/wiki/Software_floating_point> - parts of that page are obviously out of date, but this item still applies). Doing this requires first that the functions are actually available from libc for new links, not just as compat symbols. This patch stops the symbols in question being compat symbols for powerpc-nofpu. The nofpu Versions entries for them are removed (the symbols never were exported at GLIBC_2.3.2, only GLIBC_2.0, because the compat symbols took precedence). Tested powerpc-nofpu. The symbols are no longer compat symbols and libm.so now properly gets undefined references to them (resolved to libc.so) instead of the libgcc copies getting linked into libm as before. * sysdeps/powerpc/powerpc32/libgcc-compat.S [_SOFT_FLOAT || __NO_FPRS__] (__fixdfdi_v_glibc20): Do not define as a macro and a compat symbol.
