Hi all, As we see from gcc doc, the builtins are intended to be compatible with those described in the Intel Itanium Processor-specific Application Binary Interface, section 7.4. Why did gcc for x86 miss expanding such built-ins, just generating a call to an external function? Is it on purpose or TODO work?
