From 2fff1e196d9cf03a868e99da39ea21b7c18c65c5 Mon Sep 17 00:00:00 2001 From: Charles Bailey Date: Sun, 12 Nov 2017 16:59:38 +0000 Subject: grep: fix NO_LIBPCRE1_JIT to fully disable JIT MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit If you have a pcre1 library which is compiled with JIT enabled then PCRE_STUDY_JIT_COMPILE will be defined whether or not the NO_LIBPCRE1_JIT configuration is set. This means that we enable JIT functionality when calling pcre_study even if NO_LIBPCRE1_JIT has been explicitly set and we just use plain pcre_exec later. Fix this by using own macro (GIT_PCRE_STUDY_JIT_COMPILE) which we set to PCRE_STUDY_JIT_COMPILE only if NO_LIBPCRE1_JIT is not set and define to 0 otherwise, as before.
