Restore the `libunwind.h` enumeration values back to the inverted values. This diverges from the DWARF definition of the register values. However, this allows our header to be compatible with other unwind implementations (e.g. HP, GNU Savannah, GCC). The register IDs are only swapped in the header and need to be unswapped when accessing the unwind register file. The flipped EBP and ESP only applies on non-Apple x86 targets. When optimizations were enabled, EBP and ESP would no longer be equivalent. As a result, the incorrect access on Linux would manifest as a failure to unwind the stack. We can now unwind the stack with and without FPO on Linux x86. Resolves PR30879! llvm-svn: 292723 |
