This commit implements the correct lowering of the COPY_STRUCT_BYVAL_I32 pseudo-instruction for thumb1 targets. Previously, the lowering of COPY_STRUCT_BYVAL_I32 generated the post-increment forms of ldr/ldrh/ldrb instructions. Thumb1 does not have the post-increment form of these instructions so the generated assembly contained invalid instructions. Passing the generated assembly to gcc caused it to complain with an error like this: Error: cannot honor width suffix -- `ldrb r3,[r0],#1' and the integrated assembler would generate an object file with an invalid instruction encoding. This commit contains a small test case that demonstrates the problem with thumb1 targets as well as an expanded test case that more throughly tests the lowering of byval struct passing for arm, thumb1, and thumb2 targets. llvm-svn: 192916 |
