Subject: [PATCH 04/27] New file: gcc/jit/notes.txt
Date: Wed, 01 Jan 2014 00:00:00 -0000 [thread overview]
Message-ID: <1414774977-25605-5-git-send-email-dmalcolm@redhat.com> (raw)
In-Reply-To: <1414774977-25605-1-git-send-email-dmalcolm@redhat.com>
An earlier version of this was posted as part of:
"[PATCH 06/10] Heart of the JIT implementation (was: Re: [PATCH 0/5] Merger of jit branch (v2))"
https://gcc.gnu.org/ml/gcc-patches/2014-10/msg01247.html
I've broken that up into separate patches for ease of review.
This first patch within gcc/jit adds a high-level overview
diagram of how the JIT library works.
