Suboptimal code generation by GCC

["Gunnar Von Boehn" <gunnar@xxxxxxxxxxxxxx>]

To whom it may concern,

We have evaluated the "gcc version 4.2.1 (Sourcery G++ Lite 4.2-47)"
Compiling various test cases it showed that the the ASM code created
by GCC 4.2.1 for 68k/Coldfire platform was not optimal.
Comparing ASM output created by GCC 2.9 with GCC 4.2, the generated
code got partially much worse with GCC 4.

I have filed some bug report to the GCC team to help them rectify this issues.
The found problems were described in these tickets:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36133
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36134
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36135
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36136

I think, I would be nice if you could have a look and help them to fix
those issues.

Please tell me if you need anything more from me to help you.


Kind regards
