| 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. | |
