| # 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. |
