[PATCH] D106198: [DWP] Refactoring llvm-dwp in to a library.

[Alexander Yermolovich via Phabricator via llvm-commits]

ayermolo added a comment.

I guess on thing that can simplify BOLT. In some cases skeleton CU doesn't have DW_AT_GNU_ranges_base. In general bolt converts DW_AT_low_pc/DW_AT_high_pc to ranges. If Skeleton CU doesn't have DW_AT_GNU_ranges_base we replace DW_AT_low_pc with it. Except DW_AT_GNU_ranges_base doesn't fit in 8 bits. So Abbrev section can't be patched, and I ended up re-writing it. Not sure what can be done there. Maybe llvm can always emit DW_AT_GNU_ranges_base in Skeleton CU?
