of codes. For example,
short kernel (short t1) {
t1 >>= 8; t1 <<= 8;
return t1;
}
became:
short %kernel(short %t1.1) {
%tmp.3 = shr short %t1.1, ubyte 8 ; <short> [#uses=1]
%tmp.5 = cast short %tmp.3 to int ; <int> [#uses=1]
%tmp.7 = shl int %tmp.5, ubyte 8 ; <int> [#uses=1]
%tmp.8 = cast int %tmp.7 to short ; <short> [#uses=1]
ret short %tmp.8
}
before, now it becomes:
short %kernel(short %t1.1) {
%tmp.3 = shr short %t1.1, ubyte 8 ; <short> [#uses=1]
%tmp.8 = shl short %tmp.3, ubyte 8 ; <short> [#uses=1]
ret short %tmp.8
}
which will become:
short %kernel(short %t1.1) {
%tmp.3 = and short %t1.1, 0xFF00
ret short %tmp.3
}
This implements cast-set.ll:test4 and test5
