Hi Zoltan

The patch attached to your comment #20 works fine on Fedora/PPC64-BE but fails
on Ubuntu/PPC64-LE.

============= Fedora/PPC64-BE :

# patch -p0 < ../pcre-8.34.ppc.patch
patching file sljit/sljitConfigInternal.h
patching file sljit/sljitLir.c
patching file sljit/sljitNativePPC_common.c

# export CFLAGS="-O0 -g -Wall" ; export LDFLAGS="-g" ; ./configure
--enable-shared=no --enable-pcre16 --enable-unicode-properties --enable-jit
...
    Enable JIT compiling support .... : yes
...


# make

# make test
...
PASS: pcre_jit_test
...

============ Ubuntu/PPC64-LE :

$ patch -p0 < ../pcre8.34.ppc.patch
patching file sljit/sljitConfigInternal.h
patching file sljit/sljitLir.c
patching file sljit/sljitNativePPC_common.c

$ ./configure --enable-shared=no --enable-pcre16 --enable-unicode-properties
--enable-jit ; make ; make test
...
Enable JIT compiling support .... : yes
...

./test-driver: line 95: 19365 Illegal instruction     (core dumped) "$@" >
