| Subject: [PATCH 15/16] [LOCAL]: upstream change to garbage collection sweep |
| causes mb regression |
| |
| Upstream change for PR13177 now clears the def_regular during gc_sweep of a |
| section. (All other archs in binutils/bfd/elf32-*.c received an update |
| to a warning about unresolvable relocations - this warning is not present |
| in binutils/bfd/elf32-microblaze.c, but this warning check would not |
| prevent the error being seen) |
| |
| The visible issue with this change is when running a c++ application |
| in Petalinux which links libstdc++.so for exception handling it segfaults |
| on execution. |
| |
| This does not occur if static linking libstdc++.a, so its during the |
| relocations for a shared lib with garbage collection this occurs |
| |
