[PATCH] D103028: [llvm][ARM] Add CPU defs for arm2/3/6/7m

[Peter Smith via Phabricator via llvm-commits]

peter.smith added a comment.

Does LLVM generate correct code for those architectures? For example armv3 doesn't have BX LR, it must use MOV PC, LR or emit BX LR with an R_ARM_V4BX relocation so the linker can transform it.  From memory I think armv2 doesn't even use 32-bit addresses, the flags were stored in the top 8 bits.
