Hello Jakob, thanks for the reply. The three regclasses involved here are all subsets from each other and aren't disjoint.

Hi, I'm having some trouble wirting an instruction in the X86 backend. I made a new intrinsic and I wrote a custom inserter for my intrinsic in the X86 backend. Everything works fine, except for one instruction that I can't find how to write. I want to add this instruction in one of my machine basic block: mov [rdi], 0 How can I achieve that with the LLVM api? I tried several

Hey Ryan, You end with a large constant immediate offset value because the register operand stores the register id in a union together with the offset that's used by the global address operand. Just add 'setOffset(0)' to your change method and that should solve your problem. 2015-06-16 9:15 GMT-07:00 Ryan Taylor <ryta1203 at gmail.com>: > So I have this for
