Subject: [PATCH] mmap tail merging
Date: Wed, 15 Aug 2001 18:41:03 -0400 (EDT) [thread overview]
Message-ID: <Pine.LNX.4.33.0108151837050.12167-100000@touchme.toronto.redhat.com> (raw)
In-Reply-To: <Pine.LNX.4.33.0108151539240.28240-100000@touchme.toronto.redhat.com>
Hello,
Here's a patch to mmap.c that performs tail merging on mmap. In testing,
ld tends to hit it a few times during linking, and mozilla hit it a couple
of dozen times. This probably comes from larger blocks of memory that
were malloc'd and later free'd with the following memory segment still in
use. Alas, that doesn't solve all of the excess vma's in mozilla.
