Comment 1 Sam James archtester Gentoo Infrastructure gentoo-dev Security 2023-01-31 17:27:58 UTC 
Indeed, libpcre2 has no JIT support for sparc at all right now.

We mask it on the 64bit profile but not 32bit.
``` 
$ grep -rsin libpcre2 profiles/arch/sparc
profiles/arch/sparc/64ul/package.use.mask:11:dev-libs/libpcre2 jit
```

libpcre1 however did support 32-bit sparc for jit.
