It is not clear who has initiated this wish.Few years back, when I ported the interpreted version of PCRE to classic z/OS, Zoltan wanted to develop JIT version for the IBM mainframe. At the time, both Phil and I had discouraged it due to the proprietary nature of that platform. If anybody wants to do it, then please be aware that tis is a very complex CISC system and IBM continues to develop it and at time keeps things unpublished.As akways, I will be mire than glad to share my experience with that platform

Goal is full functionality and passing testsuite with JIT enabled. An unfinished port of PCRE2 JIT to s390x exists in the Linux-on-IBM-z Github account and can be used as a starting point. IBM will contribute the code as necessary. https://github.com/linux-on-ibm-z/pcre2/tree/s390x-experimental -- You are receiving this mail because: You are on the CC list for the bug. -- ## List details at https://lists.exim.org/mailman/listinfo/pcre-dev -- ## List details at https://lists.exim.org/mailman/listinfo/pcre-dev
