Backport Requst #39

Closed FlyGoat closed 6 years ago

FlyGoat commented 6 years ago

Hi @xiangzhai;

Recently, Paul Hua submitted a set of patches to mainline GCC[1] and Binutils. They should be merged within GCC-9.1 window.

I'm wondering if it's possible to backport these patches to our current loongson-community GCC tree for GCC-8.1 and Binutils 2.30, so Lemote Fedora28 can enjoy these enhancements?

Thanks.

xiangzhai commented 6 years ago

OK, I will backport them :)

Request for Review: Backport reorganize the loongson march and extensions instructions set to gcc-8.1.0

Hi @FlyGoat

I would like to backport the refactory loongson march and LoongISA to gcc-8.1.0.

The backport is mostly the same as the version that will be merged by upstream in 9, congratulations Xu Chenghua :)

Please review the patch, and run the testcase for double check. Thanks a lot!

Regards, Leslie Zhai

Hi @FlyGoat

I would like to backport the refactory loongson march and LoongISA to gcc-8.1.0.

The backport is mostly the same as the version that will be merged by upstream in 9, congratulations Xu Chenghua :) but except that:

  • gcc/config/mips/loongson.h Introduce new loongson-mmiintrin.h
  • gcc/config/mips/loongson.md Remove
  • gcc/config/mips/mips.h Replace LOONGSON3A with GS464
  • gcc/config/mips/mips.md Introduce new loongson-mmi.md
  • gcc/config/mips/mips.opt Introduce loongson-mmi
  • gcc/config/mips/mips-tables.opt Replace octeon with gs464, then increase Value
  • Replace if condition for target_flags |= MASK_LOONGSON_MMI

Please review the patch, and run the testcase for double check. Thanks a lot!

Regards, Leslie Zhai

Thanks for your work! I'm going to try it on GS464 and GS464E. However, it's hard for me to test on GS264E environment since my LoongsonPI is still repairing, and Loongson had not release board specific kernel for LoongsonPi with MSA instruction set support.

And should binutils also be patched? At least we should add the machine flag for gas and identify it in elf parser.

I will run the regression testcase via cross compiler toolchain on 4.13.16-100.fc25.x86_64

And should binutils also be patched?

Ditto :) https://github.com/loongson-community/binutils-gdb/issues/3

And should gcc/config/mips/t-st also be modified to fit the new multilib of -march?

Yeah... And some compiler internal issue appeared during build the GCC with patched Binutils. I don't know how to collect the build log. Is it convenient for you to give me a rsa public key so you can login to my machine via ssh and see what's going on?

Thanks

But gcc-6.4.3 on Linux x86_64.fc25 is not able to reproduce the issue https://github.com/loongson-community/binutils-gdb/issues/3#issuecomment-423791804 I will find the root cause.

Thanks I'll keep this machine online.

Workaround bootstrap use gcc-6.4.3 or older https://github.com/loongson-community/binutils-gdb/issues/3#issuecomment-423791804

FlyGoat commented 6 years ago

I'm going to close this issue and create a new issue for the ICE problem.
