Issue ID: 23077
Summary: codegen cannot generage XMM load/store for optimized
operation that uses byte/short/...
Product: D
Version: D2
Hardware: x86_64
OS: All
Status: NEW
Severity: blocker
Priority: P1
Component: dmd

The following code produces an Illegal instruction (core dumped) on the
compiler:
float bug(float x) {
short i = *cast(short*)&x;
++i;
return *cast(float*)&i;
}
The codegen try to generate optimized calls with XMM opcodes but fail to do it.
This might happen to other types too.
