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. ----------------------------------------------------------------------- Summary of changes: ChangeLog | 6 ++++++ NEWS | 2 +- sysdeps/powerpc/nofpu/Makefile | 1 + 3 files changed, 8 insertions(+), 1 deletions(-) -- You are receiving this mail because: You are on the CC list for the bug.
