when the types match up. This allows the X86 backend to compile:
sbyte %toggle_value(sbyte* %tmp.1) {
%tmp.2 = load sbyte* %tmp.1
ret sbyte %tmp.2
}
to this:
_toggle_value:
mov %EAX, DWORD PTR [%ESP + 4]
movsx %EAX, BYTE PTR [%EAX]
ret
instead of this:
_toggle_value:
mov %EAX, DWORD PTR [%ESP + 4]
movsx %EAX, BYTE PTR [%EAX]
movsx %EAX, %AL
ret
