            Bug ID: 2240
           Summary: Failed build on MIPS ci20 with JIT support
           Product: PCRE
           Version: 8.41
          Hardware: Other
                OS: Linux
            Status: NEW
          Severity: bug
          Priority: medium
         Component: Code
          Assignee: ph10@???
          Reporter: noloader@???
                CC: pcre-dev@???


I'm working on a MIPS ci20 dev-board (https://creatordev.io/ci20.html). There's
not much support so it is hard to find stable images. The stable image is old
Debian so I need to build some things from sources, like Git.

This appears to be a different issue than Bug 1350, JIT doesn't compile on
MIPS/uclibc.

The error is:

sljit/sljitNativeMIPS_common.c: In function 'sljit_has_cpu_feature':
sljit/sljitNativeMIPS_common.c:506:3: error: a label can only be part of a
statement and a declaration is not a statement

And:

$ cat -n sljit/sljitNativeMIPS_common.c
   ...
   499  SLJIT_API_FUNC_ATTRIBUTE sljit_s32 sljit_has_cpu_feature(sljit_s32
feature_type)
   500  {
   501          switch (feature_type) {
   502          case SLJIT_HAS_FPU:
   503  #ifdef SLJIT_IS_FPU_AVAILABLE
   504                  return SLJIT_IS_FPU_AVAILABLE;
   505  #elif defined(__GNUC__)
   506                  sljit_sw fir;
   507                  asm ("cfc1 %0, $0" : "=r"(fir));
   508                  return (fir >> 22) & 0x1;
   509  #else
   510  #error "FIR check is not implemented for this architecture"
   511  #endif
   ...
