[PATCH] Apply the regparm and stdcall attributes to internal regexfunctions
- From: Paolo Bonzini <paolo dot bonzini at polimi dot it>
- To: libc-alpha at sources dot redhat dot com
- Date: Wed, 17 Dec 2003 14:37:27 +0100
- Subject: [PATCH] Apply the regparm and stdcall attributes to internal regexfunctions
- Reply-to: bonzini at gnu dot org
This achieves a small but consistent 1% improvement in the sed testsuite
(gcc 3.4 has unit-at-a-time mode which does this at -O2).
