--- Comment #7 from H.J. Lu <hjl.tools@???> ---
I pushed a new patch to
1. Add sljit_emit_ijump_target_start to emit a start instruction at
indirect jump target and call it after sljit_set_put_label(...) in
pcre2_jit_compile to add ENDBR32/ENDBR64 at indirect jump targets.
2. Define ECX_REG to use ECX as scratch register to unwind shadow stack
when returning from JIT.
Tested on i686/x86-64 CET/non-CET Linux machines with
$ CC="gcc -Wl,-z,cet-report=error -fcf-protection -mshstk" ./configure
--enable-jit
