2014-01-03Fix soft-float ldbl-128ibm atan2l signs of zero results (bug 16390).Joseph Myers
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.

2013-12-19Don't make soft-fp symbols compat symbols for powerpc-nofpu.Joseph Myers
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 - parts of that page are obviously out of date, but this item still applies).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.
