Does anybody know if WinARM supports Thumb2 Intruction set and the
Cortex-M3 core in particular ?

All the best!

I don't think so but I have not tried it. The gcc in WinARM 6/06 is
build from the "official" gcc 4.1.1 sources. So you might check if the
gcc-manual for this release already mentions thumb2.

The Codecourcery GNU-toolchain supports the M3 (from
http://www.codesourcery.com/gnu_toolchains/arm/: "Support for ARM V7,
including Cortex-M3"). I'm not sure if the modifications made by
codesourcery are already included in the "official" gcc-sources.

This morning I was able to compile a test application for Luminary
Stellaris using Yagarto tools, the CodeSourcery libraries and the
Luminary Driver Library which can be downloaded at their site

http://www.luminarymicro.com/products/software_updates.html

I don't have any hardware, but the memory dump looks correct and I can
call the peripheral functions from the library without error messages!!!

Waiting to get an eval board - soon - I hope
