That is correct in the case of your example: > PCRE version 8.38-RC1 2015-05-03 > /a/S++2 > a > 0: a You have selected JIT compilation only for a search that permits a partial match. The digit works like this: 1 normal match only 2 soft partial match only 3 normal match and soft partial match 4 hard partial match only 6 soft and hard partial match 7 all three modes (default) You have not asked for JIT compilation for a non-partial-match search, so JIT code is not used (the match was found by the interpreter code), and so therefore "(JIT)" is not output. If you do a search for an appropriate partial match, you will see "(JIT)": PCRE version 8.38-RC1 2015-05-03 re> /a/S++2 data> a\P 0: a (JIT) data> a\P\P 0: a Perhaps the documentation isn't entirely clear. I will take a look at the PCRE2 equivalent documentation, to see if it can be improved. Philip -- Philip Hazel -- ## List details at https://lists.exim.org/mailman/listinfo/pcre-dev
