[llvm-dev] [RISCV] Status of LTO for RISC-V
Hi all, I wanted to use LTO with the rv32 target and stumbled upon some open patches and wanted to ask what the status is on LTO for RISC-V? Related patches: [RISCV] enable LTO support, pass some options to linker. https://reviews.llvm.org/D67409 [WIP] TargetMachine Hook for Module Metadata https://reviews.llvm.org/D72624 pass -mabi to LTO linker only in RISC-V targets, enable RISC-V LTO https://reviews.llvm.org/D71387 [PoC][RISCV] enable LTO/ThinLTO on RISCV https://reviews.llvm.org/D78035 If this is still WIP I would be happy to contribute.

Hi Noah This year I have a new patch D102582 for enabling LTO in RISC-V. D102582 changes the target-abi mismatched checking mechanism because allowing the module flag in IR to overwrite the empty target-abi options does not doable. Then D71387 is used to enable LTO for RISC-V. - Zakk Alex Bradbury via llvm-dev <llvm-dev at lists.llvm.org> 於 2021年6月27日 週日 下午5:57寫道：> On Thu, 24 Jun 2021 at 16:07, Noah Hütter via llvm-dev > <llvm-dev at lists.llvm.org> wrote: > > > > Hi all, > > > > I wanted to use LTO with the rv32 target and stumbled upon some open > > patches and wanted to ask what the status is on LTO for RISC-V? > > > > Related patches: > > > > [RISCV] enable LTO support, pass some options to linker. > > https://reviews.llvm.org/D67409 > > [WIP] TargetMachine Hook for Module Metadata > > https://reviews.llvm.org/D72624 > > pass -mabi to LTO linker only in RISC-V targets, enable RISC-V LTO > > https://reviews.llvm.org/D71387 > > [PoC][RISCV] enable LTO/ThinLTO on RISCV > > https://reviews.llvm.org/D78035 > > > > > > If this is still WIP I would be happy to contribute. > > Hi Noah - to my knowledge nobody has been pushing this work forwards > of late, so contributions would definitely be welcome. > > Best, > > Alex > _______________________________________________ > LLVM Developers mailing list > llvm-dev at lists.llvm.org > https://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-dev >-- Best regards, Kuan-Hsu -------------- next part -------------- An HTML attachment was scrubbed...
