Maybe just revert this commit is a good approach for now, it won't affect other
functions, and later on someone upload new patch to implement this cm.popretz
generation

I tried to revert this commit
https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=b27d323a368033f0b37e93c57a57a35fd9997864

Then the wrong generated cm.popretz is removed, and it now works as expected,
could somebody check whether there is a better solution to this patch.

Thanks

> You mean you want to disable it when disabling auto-vectorization ?

Yes, I think this could be better, so we can control whether vector instruction
should be generated, and if auto generated rvv instruction is not good, we can
enable it via gcc pragma control for selected code block.

Thanks

Hi Juzhe, thanks for the help, could it be controlled by
--param=riscv-autovec-preference= option, so if I want to enable cpymem
optimization, I can enable it by auto vectorzation.

Thanks

Bug ID: 112537
   Summary: Is there a way to disable cpymem pass for rvv
   Product: gcc
   Version: 14.0
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: c
  Assignee: unassigned at gcc dot gnu.org
  Reporter: fanghuaqi at vip dot qq.com
  Target Milestone: ---

See
https://gcc.gnu.org/git/?p=gcc.git;a=blob;f=gcc/testsuite/gcc.target/riscv/rvv/base/cpymem-2.c;h=7b706b6ef52544cabdce2007256c9e67b72ccd79;hb=9464e72bcc9123b619215af8cfef491772a3ebd9
this case, if I pass -march=rv64imafdcv to compile code like this, it will
generate vector related code, which I think it should only be enabled when
--param=riscv-autovec-preference=scalable is enabled, but actually it is auto
enable d even I pass  --param=riscv-autovec-preference=none, see
https://godbolt.org/z/TazWKEjzM

Is there a way to disable it, since if vector load and store for smaller
structure assign is costable and harmfull to cpu pipeline.

Thanks

[Bug c/109460] Build gcc for win32 failed in gcc13 master branch

--- Comment #9 from Huaqi  ---
Hi, Costas Argyris,

I am using this repo to help build toolchain, the repo link is here:

https://github.com/riscv-collab/riscv-gnu-toolchain

clone this source code and its submodule, and change gcc to upstream version

git clone https://github.com/riscv-collab/riscv-gnu-toolchain.git
git submodule update --init --recursive --depth 1
cd gcc
# fetch upstream gcc source code
git fetch --all
git checkout master
cd ..

Tested in Ubuntu 18.04, with packages binutils-mingw-w64-i686
gcc-mingw-w64-i686 g++-mingw-w64-i686 binutils-mingw-w64-i686 installed and
other requirements in
https://github.com/riscv-collab/riscv-gnu-toolchain#prerequisites.


build command:

mkdir build
cd build
../configure --prefix=$(pwd)/install --with-host=i686-w64-mingw32 
--enable-multilib
make -j16

Then you will be able to reproduce this issue.

Thanks

I think it might be introduced by this commit
https://github.com/gcc-mirror/gcc/commit/304c7d44a2212e6fd618587331cea2c266dc10bf,
since I tested this commit
https://github.com/gcc-mirror/gcc/commit/4872e46e080c6695dfe1f9dc9db26b4703bc348c
it works for win32 build. After this commit, it failed.

Thanks Kito, maybe you can add more examples in this script

and in this doc

Thank you very much.

Hi there, I tried to build gcc 13 for windows host using mingw gcc in linux.
But I am facing the following issue.

i686-w64-mingw32-g++  -fno-PIE -c /work/gcc/gcc/config/i386/sym-mingw32.cc
sym-mingw32.o
i686-w64-mingw32-g++: error: sym-mingw32.o: No such file or directory
echo timestamp > s-bversion

It seems the sym-mingw32.o is not generated via this command, and I thought it
should be like gcc -c hello.c -o hello.o, so I changed
gcc/config/i386/x-mingw32-utf8
