[LLVMdev] wrong code generation for memcpy function in SROA optimization pass
...8]*@.str,i32 0,i32 0),i32 %conv),
ret i32 0,
}
IR after SROA:
define i32 @main() #0 {
entry:
%conv = sext i8 undef to i32,
%call = call i32 (i8*,...)* @printf(i8* getelementptr inbounds([9*i8]*@.str,i32 0,i32 0),i32 %conv),
ret i32 0,
}
Then I tried to debbuging with SROA.cpp,I found in funcction visitMemTransferInst,it accorded the IR instruction "call void @llvm.memcpy.p0i8.p0i8.i32(i8* %ch,i8* %0,,i32 2,i32 1,i1 false)",would produce such codes(finally,memcpy disappeared and the codes would be delated,IR after SROA become incorrect ,am i right?)
%sh.0.cast = bitcast i8* ch to i...

the arguments and optional return values.
