Hi LLVM developers, Don't be quiet :) we need your suggestions for supporting custom CCState, CCAssignFn in D41700. And also RegisterBank in D41653. because it needs to consider about how to support variable-sized register classes concept implemented in D24631. And I think you might have same question when porting to GlobalISel for your Targets, so please give us some directions, thanks a lot! 在 2018年01月0...

...ng the issue for gcc-6/7 branches and gcc-8 trunk. 非常感谢！龙芯战士们临近春节还奋战在Mozilla、Linux Kernel、GCC、Binutils，但依然抽出休息时间审核我的工作，非常感激！ 在 2018年01月13日 18:58, Leslie Zhai 写道: > Hi LLVM developers, > > Don't be quiet :) we need your suggestions for supporting custom > CCState, CCAssignFn in D41700. > > And also RegisterBank in D41653. because it needs to consider about > how to support variable-sized register classes concept implemented in > D24631. > > And I think you might have same question when porting to GlobalISel > for your Targets, so please give us some direc...

This question came about through reviewing work from Leslie Zhai on GlobalISel support for RISC-V, which also motivated me to revisit code which I've always felt was a bit clunky. Calling convention lowering in LLVM is typically handled by functions conforming to the CCAssignFn typedef: typedef bool CCAssignFn(unsigned ValNo, MVT ValVT, MVT LocVT,

Hi all, Over the past few months we’ve been doing work on the foundations for the next stages of GlobalISel development. In terms of changes from this time last year, the IR translator, the legalizer, and instruction selector have seen moderate to major changes. The most significant of these was the change to the legalizer API, allowing targets to use predicates to express legality, which gives
