Subject: [ARM] gcc 4.6

[ARM] gcc 4.6

From: Rafaël Carré <rafael.carre_at_gmail.com>
Date: Sun, 19 Sep 2010 14:48:08 +0200

Hi,

I tested the last gcc 4.6.0 snapshot today (20100918) with binutils CVS
and I got some interesting results to share.

All results are for Clipv2.

------------------------------------------------------------------------

I could build binaries for Clipv2 (with and without -flto) and Clipv1
(without -flto) and they ran and played music fine.

------------------------------------------------------------------------

-flto doesn't help a lot for codec speed, the difference between -flto
and nothing is below 1% (both faster or slower) except for:
        vorbis_192 (5% slower)
        cook_stereo_32 (1.6% slower)

All codecs are slower with flto but WMA standard, FLAC and AAC-LC

------------------------------------------------------------------------

The difference between gcc 4.4 and gcc 4.6 is quite bigger though:
        APE is faster (3.5% for c1000, 0.12% for c5000)
        Apple lossless is 4.5% faster
All other codecs are slower (FLAC is 25% slower!)

(I attach test_codec results for gcc-4.4, gcc-4.6 with -flto and gcc-4.6
without -flto).

------------------------------------------------------------------------

RAM usage is:
384 bytes bigger when built with gcc-4.6
24.4kB lower when built with -flto

------------------------------------------------------------------------

BUGS:

Error: selected processor does not support ARM mode `movteq r5,64'
When compiling apps/plugins/goban/sgf.c
-> reported on http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45726

Clipv1 doesn't build with -flto (due to -mthumb)
-> reported on http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45727
(and I found an ICE when making the bug report :p )

------------------------------------------------------------------------

Warnings:
GCC gives a lot of new warnings, especially because of the new
-Wunused-but-set-variable , I'm pasting the list below, having a look
at this would be nice because most of them highlight real bugs.
