Subject: [RFC PATCH 1/2] grep: make sure NO_LIBPCRE1_JIT disable JIT in PCRE1
Date: Fri, 26 Jul 2019 13:26:41 -0700 [thread overview]
Message-ID: <20190726202642.7986-2-carenas@gmail.com> (raw)
In-Reply-To: <20190726202642.7986-1-carenas@gmail.com>
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.
