From 8991da6a3864d93d860afe4c510b4fdbf0da6363 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Carlo=20Marcelo=20Arenas=20Bel=C3=B3n?= Date: Sun, 25 Aug 2019 11:22:22 -0700 Subject: [PATCH] grep: make sure NO_LIBPCRE1_JIT disable JIT in PCRE1 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit e87de7cab4 ("grep: un-break building with PCRE < 8.32", 2017-05-25) added a restriction for JIT support that is no longer needed after pcre_jit_exec() calls were removed. Reorganize the definitions in grep.h so that JIT support could be detected early and NO_LIBPCRE1_JIT could be used reliably to enforce JIT doesn't get used.
