I have not compiled the latest snapshots, but I noticed a slowdown (5%)
going from egcs1.0.3a to 1.1.2 on the PPC cross compiler I built from egcs
sources.  Unfortunately I don't have a small test case to demonstrate.  I
think the default insn scheduler changed.

Subject: Performance issues of gcc-2.95


I  just  downloaded  the latest gcc snapshot and ran my favorite test
against  this  new  version.  I'm  the  author  of OpenLisp an ISLISP
implementation  already  ported  on  more  than  70  plateforms.  The
overall  performance is about 5% slower than previous gcc/egcs on the
same machine (NT4 SP5 on a Bi-pentium 400 Mhz) - 39s V.S. 37s.

See OpenLisp info on : http://www.ilog.fr:8001/Eligis/

For  information,  a  lisp  system  essentially do pointers,  shifts,
function calls and bit masks (VC++ 6.0 runs on 34.630 s)

Cyg = cygwin, Min = Mingw32
