LLVM backend for 6502
This reverts r214893, re-applying r214881 with the test case relaxed a bit to satiate the build bots. POP on armv4t cannot be used to change thumb state (unilke later non-m-class architectures), therefore we need a different return sequence that uses 'bx' instead: POP {r3} ADD sp, #offset BX r3 This patch also fixes an issue where the return value in r3 would get clobbered for functions that return 128 bits of data. In that case, we generate this sequence instead: MOV ip, r3 POP {r3} ADD sp, #offset MOV lr, r3 MOV r3, ip BX lr http://reviews.llvm.org/D4748 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@214928 91177308-0d34-0410-b5e6-96231b3b80d8 |
