labrinea updated this revision to Diff 372677.
labrinea added a comment.
Changes in this revision:
- added `-verify-machineinstrs` to the tests
- that yield two bugs that I had to address:
*** Bad machine code: Explicit operand marked as def ***
- function: func
- basic block: %bb.0 entry (0x890b6d8)
- instruction: $d3 = VSTRD $sp, 6, 14, $noreg
- operand 0: $d3
*** Bad machine code: Explicit definition marked as use ***
- function: non_secure_call
- basic block: %bb.0 (0x8e0bed8)
- instruction: t2MRS_M $r12, 20, 14, $noreg
- operand 0: $r12
