System : OpenBSD 7.0
Details : OpenBSD 7.0 (GENERIC) #89: Sun Oct 3 10:09:54 MDT 2021

Machine : loongson
>Description:
GCC 8.4.0 and 11.2.0 from ports fails to build on Loongson
system. I've tested on 7.0-release, but as both ports has not
been updated since it may also affect -current. For both GCC
versions, the base-clang fails to compile a usable
bootstraping gcc
(/usr/ports/pobj/gcc-8.4.0/build-mips64el/./gcc/xgcc) which
ended up in ICE when trying to compile something. For GCC 8,
the configure check fails at this part:
,----
| checking size of double... configure: error: in
`/usr/ports/pobj/gcc-8.4.0/build-mips64el/mips64el-unknown-openbsd7.0/libgcc':
| configure: error: cannot compute sizeof (double)
| See `config.log' for more details.
`----
I've checked the config.log under the failing directory and
tried to rerun the commands with "-v" and it turns out to be
an ICE. The full output looks like below:

(Note that the issue for GCC 8.4.0 has been reproducible since
6.9-release.)
I understand that Loongson is a niche platform and may not
receive the same level of support as other more popular
platforms. I'd like to help debugging by providing anything
useful and any guidance or suggestions are welcome.
>How-To-Repeat:
Trying to build lang/gcc/{8,11}.
