[LLVMdev] InstructionCombining forgets alignment of globals
...duces this (I used
2.3 release). Here's the x86 code it produces:
03C20019 movaps xmm0,xmmword ptr ds:[164E799h]
03C20020 mulps xmm0,xmmword ptr ds:[164E79Ah]
03C20027 movaps xmmword ptr ds:[164E799h],xmm0
03C2002E mov esp,ebp
03C20030 pop ebp
03C20031 ret
All three SSE instructions will generate a fault for accessing unaligned
memory. Disabling InstructionCombining gives me the following correct code:
03B10010 push ebp
03B10011 mov ebp,esp
03B10013 and esp,0FFFFFFF0h
03B10019 movups xmm0,...
