Hi, both https://git.kernel.org/pub/scm/libs/klibc/klibc.git/plain/usr/klibc/arch/i386/libgcc/__ashldi3.S and https://git.kernel.org/pub/scm/libs/klibc/klibc.git/plain/usr/klibc/arch/i386/libgcc/__lshrdi3.S use the following code sequences for shift counts greater 31: 1: 1: xorl %edx,%edx shrl %cl,%edx shl %cl,%eax xorl %eax,%eax ^ xchgl %edx,%eax xchgl %edx,%eax ret ret At least and e...

Hi All, I am looking at a linker error under O2: undefined symbol __lshrdi3 I have two questions here: 1. Does that mean our libgcc (?) doesn't implement __lshrdi3? Or more generally, why I have such linker error? 2. Seems some operations are combined, and replaced with __lshrdi3 call. I am interested in when such libcall will be generated? Could you...

I have noticed that TargetGlobalAddress is generated for "source code" functions and TargetExternalSymbol is generated for builtins like __lshrdi3. What is the difference between TargetExternalSymbol and TargetGlobalAddress? Thanks, Rafael

Well, the answer is pretty obvious then. These calls are not generated by JIT. They are already in your bitcode - they are generated by llvm-gcc. The purpose of these calls were alreade explained by Eli. You should either
