I build tested your PR on mips64 and it fails on:
In file included from src/sljit/sljitLir.c:2111,
from src/pcre2_jit_compile.c:79:
src/sljit/sljitNativeMIPS_common.c: In function âsljit_emit_cmovâ:
src/sljit/sljitNativeMIPS_common.c:2253:9: warning: implicit declaration of
function âsljit_emit_cmov_genericâ; did you mean âsljit_emit_cmovâ?
[-Wimplicit-function-declaration]
return sljit_emit_cmov_generic(compiler, type, dst_reg, src, srcw);
^~~~~~~~~~~~~~~~~~~~~~~
sljit_emit_cmov
This failure can be fixed by updating sljitLir.c to define
sljit_emit_cmov_generic if SLJIT_MIPS_REV < 6.
