Which pass should be propagating memory copies
Consider the following IR example:
define void @simple([4 x double] *%ptr, i64 %idx) {
%stack = alloca [4 x double]
%ptri8 = bitcast [4 x double] *%ptr to i8*
%stacki8 = bitcast [4 x double] *%stack to i8*
call void @llvm.memcpy.p0i8.p0i8.i32(i8 *%stacki8, i8 *%ptri8, i32 32,
i32 0, i1 0)
%dataptr = getelementptr inbounds [4 x double], [4 x double] *%ptr, i32
0, i64 %idx
store double 0.0, double *%datap...
