[PATCH] D114172: [ARM] implement support for ALU/LDR PC-relative group relocations

[Ard Biesheuvel via Phabricator via llvm-commits]

ardb updated this revision to Diff 389178.
ardb added a comment.

For completeness, add support for R_ARM_LDRS_PC_Gn relocations as well. These are not as useful, given the small range of the unscaled addend, resulting in a guaranteed range of the entire group of only -/+ 16 MiB (24 bits).

Note that R_ARM_LDC_PC_Gn are still not supported, but these are even more obscure and so rarely used that I doubt whether anyone cares.
