--- Comment #10 from rcond...@hotmail.com ---
Could be totally borked, but this is what I have at the moment:
if (type.floating) {
return LLVMBuildFDiv(builder, a, b, "");
}
else {
//The spec says divide by zero is undefined, but shouldn't throw an
exception
LLVMValueRef zeromask = lp_build_cmp(bld,
PIPE_FUNC_EQUAL,
b,
lp_build_zero(bld->gallivm,type));
if (type.sign) {
return lp_build_select(bld,
zeromask,
bld->undef,
LLVMBuildSDiv(builder, a, b, ""));
}
else {
return lp_build_select(bld,
zeromask,
bld->undef,
LLVMBuildUDiv(builder, a, b, ""));
}
}
I'll take a look at udiv_emit_cpu
