[LLVMdev] ExpandDivRemLibCall vs. AEABI
...ecific condition there, and I found no hierarchy for DAGLegalize, I'm wondering what's the best approach. Two options could be: * Creating a feature (HasDivRemRegister or whatever) and hard-code AEABI together with the hard-coded GNU * Have some call-back mechanism, possibly upon a flag (HasSpecialDivRemLowering), and update the remainder result Both are ugly... :( Is there anything like that elsewhere, that would hopefully be implemented inside ARM's tree, that I could follow? cheers, --renato -------------- next part -------------- An HTML attachment was scrubbed...

[LLVMdev] ExpandDivRemLibCall vs. AEABI
Hi Renato, > * Have some call-back mechanism, possibly upon a flag > (HasSpecialDivRemLowering), and update the remainder result If you setOperationAction on SDIVREM and UDIVREM to Custom you can expand the rtlib call appropriately yourself. There's precedent for sincos on Darwin systems (both ARM and x86) and in AArch64 for basically every operation on fp128. Cheers. Tim.
