Hi all, I'm trying to understand which ABIs are supported in the PowerPC backend and I'm getting a bit confused. Here's what I've gathered so far alongside with some questions. - In PPCSubtarget.h there's DarwinABI, SVR4ABI and ELFv2ABI. - The CodeGenerator documentation claims that the AIX PowerPC ABI is followed (with som...

Hi all. There are two steps in LTO codegen so the problem is how to pass ABI info into LTO code generator. The easier way is pass -target-abi via option to LTO codegen, but there is linking issue when linking two bitcodes generated by different -mabi option. (see https://reviews.llvm.org/D71387#1792169) Usually the ABI info for a file is derived from target triple, mcpu o...

Right. I think that's what we ended up doing rather than a more general attribute on the module itself. *shrugs* Probably ok? I'd probably prefer not to have to have target code to do the evaluation if possible, but everything is weird and an edge case - mips abis more than some :) -eric On Wed, Jan 8, 2020 at 8:58 AM David Blaikie <dblaikie at gmail.com> wrote: > Oh, I should say - the module flags metadata also has support for "error > if you try to merge two modules with different values for this flag". > > On Wed, Jan 8, 2...

I also work on the RISC-V backend, and have been doing a little work on the ELF psABI document for RISC-V. I agree that, conceptually, the psABI choice should be in the module metadata. Zakk, however, has discovered a phase ordering issue within LLVM that relates to this approach. The phase ordering problem is that the LTO backend is currently setup without interrogating the curre...

Thank you very much for your information and documents! Why Imagination Technologies do not offer the latest MIPS ABI document download link just like the ISA docs? If they thought no much people interested in that doc, they had to make greate effort on compiler like GCC,LLVM by themself,then why GCC disagree with some MIPS ABI, it should be freely designed by MIPS ABI designer and compiler backend target implemen...
