A reduced test case
The trunk fails to build on sh4-unknown-linux-gnu with an ICE
during compiling libgomp. A reduced case attached fails with:

--- Comment #1 from Kazumoto Kojima <kkojima at gcc dot gnu.org> ---
sh.c:prepare_move_operands has the code for TLS addresses which
shouldn't be run when reload in progress in the first place.
I'm testing the patch below.
