24 | /* WORKAROUND pr80556: |
| 25 | For x86_64 Darwin10 and later, the unwinder is in libunwind (redirected | |
| 26 | from libSystem). This doesn't use the keymgr (see keymgr.c) and therefore | |
| 27 | the calls that libgcc makes to obtain the KEYMGR_GCC3_DW2_OBJ_LIST are not | |
| 28 | updated to include new images, and might not even be valid for a single | |
| 29 | image. | |
| 30 | Therefore, for 64b exes at least, we must use the libunwind implementation, | |
| 31 | even when static-libgcc is specified. We put libSystem first so that | |
| 32 | unwinder symbols are satisfied from there. */ | |
