  13 # The follow CFLAGS are a work around for GCC Bugzilla Bug 29253
  14 # "expand_abs wrong default code for floating point"
  15 # As this is not a regression, a fix is not likely to go into
  16 # gcc-4.1.1 and may be too late for gcc-4.2.  So we need these flags
  17 # until the fix in a gcc release and glibc drops support for earlier
  18 # versions of gcc.

  20 # This bug can cause wrong signs of zero results from fabsl, and
  21 # spurious "invalid" exceptions from comparisons with NaN in the
  22 # default code sequence generated.  The fpclassify expansion used by
  23 # __builtin_fpclassify, which is used in the absence of
  24 # -fsignaling-nans, uses __builtin_fabsl, and is not affected by
  25 # -fno-builtin-fabsl, so requiring -fsignaling-nans for some affected
  26 # source files.
