[PATCH] D86256: [libunwind] Make .eh_frame scanning/caching optional

[Ryan Prichard via Phabricator via llvm-commits]

rprichard added a comment.

The Linux ABI Extensions spec <https://raw.githubusercontent.com/wiki/hjl-tools/linux-abi/linux-abi-draft.pdf> describes the binary search table of .eh_frame_hdr as optional, so maybe falling back to .eh_frame scanning could be necessary to accommodate some ELF files? I wonder what situation results in an omitted search table. ld.bfd does have code for outputting .eh_frame_hdr without a search table.
