I try to build gcc cross-compiler for TI TMS320C4x. The OS is Linux (SUSE).
The gcc cross compiler version is 3.4.4.
An error occurs : "internal compiler error: in reload_cse_simplify_operands,
at postreload.c:391".
Has some body an idea about the reason of this error? Is it a bug or a
mistake in my script or another reason?
A bug I suppose...

Maybe using a '-O' or even '-O0' instead of '-O2' in the
'$build/gcc/Makefile's 'LIBGCC2_CFLAGS' could
enable this succeeding...
Everything depends on your goal with this... For instance the need for
this '-msmall' specific 'libgcc.a'.
Ok, you got an ICE and that should be reported :
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
What about trying the 'bug-fix' gcc-3.4.6 release and the latest
gcc-3.4.7 snapshots? Why on earth to
use the gcc-3.4.4 sources at all when there are newer bug-fixed
sources? Maybe not your 'bug' yet
being fixed but who knows...
