[LLVMdev] Misaligned SSE store problem (with reduced source)
Using LLVM 2.9, the following LLVM IR produces invalid x86 32 bit assembly (a misaligned SSE store). ; ModuleID = 'MisalignedStore' define void @MisalignedStore() nounwind readnone { entry: %v = alloca <4 x float>, align 16 store <4 x float> zeroinitializer, <4 x float>* %v, align 16 br label %post-block post-block: %f = alloca float ret void } If I feed this to llc with -march=x86, the follo...
