(In reply to comment #2)

Neither. 

This breakdown is with the rtems-4.11-lm32-rtems4.11-gcc rpm, 
i.e. it is built from the gcc-4.5.0-RC-20100406 candidate tarball.

Also, unlike what you write in 
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43527#c1
(compiles at -O0, doesn't compile at -O1), this breakdown is with -O0.

This is the same as 43805. Looks like it can be fixed by removing
GO_IF_MODE_DEPENDENT_ADDRESS from lm32.h. I'll submit a patch shotly.

------- Comment #8 from corsepiu at gcc dot gnu dot org  2010-05-27 15:15 -------
FWIW: I added your patch to the RTEMS lm32-gcc-4.5.0 toolchains.

With this patch applied, the ICE during building RTEMS, I had experienced does
not occur anymore. Compiling RTEMS at -O2 also seems to work.
