compiler-explorer: [BUG]: mips64 (el) GCC appears to actually be 32-bit

Describe the bug

The MIPS64 EL compilers (e.g. “mips64 (el) gcc 13.2.0”) appear to not actually be 64-bit, instead emitting 32-bit MIPS code.

Steps to reproduce

Visit godbolt.org
Use the “mips64 (el) gcc 13.2.0” compiler (or any other “mips64 (el) gcc”)
Observe the output being 32-bit code instead of 64-bit code (in particular visible when using e.g. void *, size_t or 64-bit arithmetic in general - which can easily be compared with the “mips64 gcc” (not el) compilers, which do emit 64-bit code

Expected behavior

I expected 64-bit code to be emitted instead of 32-bit code.

I hadn’t been able to look at this until now, but I can say it looks good to me too

Rebuilt most compilers… only 64el 13.2 and 13.1 are not happy.

Probably something stupid.
