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: p...@hermes.cam.ac.uk
Reporter: noloa...@gmail.com
CC: pcre-dev@exim.org
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
