Are P* extensions supported for 32-bit toolchain ? #1298

I am getting below error:
riscv32-unknown-elf-ar rc ../libc.a *.o
riscv32-unknown-elf-ar: ../stdlib/lib.a: No such file or directory
riscv32-unknown-elf-ar: ../time/lib.a: No such file or directory
riscv32-unknown-elf-ranlib libc.a

I used following build procedure:

$ git clone https://github.com/riscv-collab/riscv-gnu-toolchain.git
$ cd riscv-gnu-toolchain/
as mentioned in #1291 I used following repositories
$ git clone https://github.com/plctlab/riscv-gcc -b riscv-gcc-p-ext riscv-gcc-p-ext
$ git clone https://github.com/plctlab/riscv-binutils-gdb -b riscv-binutils-p-ext riscv-binutils-p-ext

$ ./configure --prefix=$RISCV32 --with-arch=rv32imafd_zpn_zifencei --with-abi=ilp32d --with-gcc-src=pwd/riscv-gcc-p-ext --with-binutils-src=pwd/riscv-binutils-p-ext
$ make

I have attached the make.log
where you can spot the actual error as mentioned below :

Please submit a full bug report,

Is the current configuration mentioned in configure command supported by the toolchain or anything missing in the procedure ?

Seem like you hit bug in their compiler implementation, cc @pz9115

It would also be good if PLCT Lab enabled the GitHub Issues section of their repo so that the issue could be reported there rather than here.

Also - just for context, issue #1298 relates back to this issue #1291 which is now closed:

I had repeated this bug, it seems exist some compatible problems with current riscv-gnu-tool chain repo. I will check it soon.

@vedanttalnikar I had fixed this bug, now you can try build again on RV32, thanks for your report.

@cmuellner / @kito-cheng / others ...

Can/should this issue be closed?

It doesn't really seem to be a valid riscv-gnu-toolchain issue as far as I can see.
It seems to be an issue with the PCLT fork of the tools:

And/or this long open PR

on the riscv-gcc repo (riscv-gcc-experiment branch):

It's still unclear to me what the precise purpose of the riscv-gcc repo is, what active development is ongoing there, and why/when anybody would use it instead of upstream gcc.

Yes, we can close this issue because it is not directly related to the riscv-gnu-toolchain repo or repositories that are referenced by the submodules.

It is a valid issue (thank you for reporting), but the issue tracker of this repo is not the right place. We don't need to be too strict on this, but after three months it is reasonable to close it here. Especially since the issue got recognition from the owner of the affected code.
