Joseph Myers 22562bb222 Fix soft-float ldbl-128ibm atan2l signs of zero results (bug 16390). ... 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.		2014-01-03 20:56:40 +00:00
