Jez Ng	622150ad5f	[lld-macho] Put GOT into `__DATA` segment where appropriate ... We were previously always emitting the GOT into `__DATA_CONST`, even for target platforms where it should end up in `__DATA`. I stumbled onto this while trying to use the `class-dump` tool -- with the wrong segment names, it fails to locate the ObjC runtime info and therefore fails to dump any classes.

Jez Ng	b41b4148e7	[lld-macho] Only enable `__DATA_CONST` for newer platforms ... Matches ld64. Reviewed By: #lld-macho, alexander-shaposhnikov Differential Revision: https://reviews.llvm.org/D105080	2021-06-30 18:55:48 -04:00
Vy Nguyen	366df11a35	[lld-macho] Rework mergeFlag to behave closer to what ld64 does. ... Details: I've been getting a few weird errors similar to the following from our internal tests: ``` ld64.lld.darwinnew: error: Cannot merge section __eh_frame (type=0x0) into __eh_frame (type=0xB): inconsistent types ld64.lld.darwinnew: error: Cannot merge section __eh_frame (flags=0x0) into __eh_frame (flags=0x6800000B): strict flags differ ld64.lld.darwinnew: error: Cannot merge section __eh_frame (type=0x0) into __eh_frame (type=0xB): inconsistent types ld64.lld.darwinnew: error: Cannot merge section __eh_frame (flags=0x0) into __eh_frame (flags=0x6800000B): strict flags differ ``` Differential Revision: https://reviews.llvm.org/D103971	2021-06-17 14:22:58 -04:00
Greg McGary	27b426b0c8	[lld-macho] Implement builtin section renaming ... ld64 automatically renames many sections depending on output type and assorted flags. Here, we implement the most common configs. We can add more obscure flags and behaviors as needed. Depends on D101393 Differential Revision: https://reviews.llvm.org/D101395	2021-05-03 21:26:51 -07:00
