Dear Maintainer,

Add 32-bit support for this architecture according to loongarch's official documentation. Link to details: https://github.com/loongson/la-toolchain-conventions

Hi,

  I just test your patch[1] for loong64, it failed:

The error log is:

checking build system type... loongarch64-unknown-linux-gnu
checking host system type... loongarch64-unknown-linux-gnu
configure: WARNING: non 32-bit pointer platform detected
configure: trying to enable 32-bit memory model compiler option for loongarch64

configure: error: bad flags, Indy
        tail -v -n \+0 config.log

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by Oaklisp configure 1.3.7, which was
generated by GNU Autoconf 2.72.  Invocation command line was

  $ ./configure --build=loongarch64-linux-gnu --prefix=/usr '--includedir=${prefix}/include' '--mandir=${prefix}/share/man' '--infodir=${prefix}/share/info' --sysconfdir=/etc --localstatedir=/var --disable-option-checking --disable-silent-rules '--libdir=${prefix}/lib/loongarch64-linux-gnu' --runstatedir=/run --disable-maintainer-mode --disable-dependency-tracking

The full build log please see attachment.

Regards,

Xiao Sheng,

Thanks for testing that -mabi=ilp32f patch.

----------------

wuruilong (and other loong folks),

Here is what the build log says:

It would seem that Debian GCC for loongarch64 did not have 32-bit
support available on the build system.

Perhaps gcc-multilib needs to be installed? That is necessary for
other 64-bit architectures that have a 32-bit mode. I could add
loongarch64 to the architecture list for gcc-multilib in the build
dependencies. But I'm not seeing it as available for loongarch64 in
https://packages.debian.org/unstable/gcc-multilib

Hi,

The current repository version of gcc does not support this option yet.
Oaklisp needs to wait for gcc to be upgraded to support it.

Hi,

I'm very sorry, Oaklisp has not been verified locally, and currently GCC
does not support it. I was very impatient to submit this bug, and I
think it's better to close this bug now. It's safer to submit the
corresponding patch after the local compilation is successful in the future.

Well, it's in the configure.ac script already so I'll just leave in
there and maybe someday it will work.
