> JIT is also used by pcregrep.
Yes but pcregrep is coded with multiple #ifdef SUPPORT_PCREGREP_JIT,
a new conditional established in config.h for that program.
It builds just fine without SUPPORT_PCREGREP_JIT even when the JIT
functions were (wrongly) not compiled in the base library.
During a transition these #defines left me thinking of what to do
from the perspective of programs using PCRE (vs. building PCRE).
They see pcre.h but not PCRE's own config.h for SUPPORT_JIT.
For the transition I've temporarily changed to:
#ifdef PCRE_INFO_JIT
pcre_free_study (our_study_ptr);
#else
pcre_free (our_study_ptr);
#endif
Code built with a pcre.h version less than 8.20 must use pcre_free().
Newer code should from now on use pcre_free_study() for releasing
a study allocation, and continue to use pcre_free() for
pcre_compile() and pcre_compile2() allocations.
All's good, and thanks again.
