# The follow CFLAGS are a work around for GCC Bugzilla Bug 29253

# "expand_abs wrong default code for floating point"

# As this is not a regression, a fix is not likely to go into

# gcc-4.1.1 and may be too late for gcc-4.2.  So we need these flags

# until the fix in a gcc release and glibc drops support for earlier

# versions of gcc.

#

# This bug can cause wrong signs of zero results from fabsl, and

# spurious "invalid" exceptions from comparisons with NaN in the

# default code sequence generated.  The fpclassify expansion used by

# __builtin_fpclassify, which is used in the absence of

# -fsignaling-nans, uses __builtin_fabsl, and is not affected by

# -fno-builtin-fabsl, so requiring -fsignaling-nans for some affected

# source files.
