Hi,
Due to the impact of ARM UAL, the Thumb1 and Thumb2 mode use LSRS
instruction while the ARM mode uses MOVS instruction. So the following case
is updated accordingly. Is it OK to trunk?
BR,
Terry

This can't be right. Thumb1 doesn't use unified syntax.

oops. You are right. Sorry for making such obvious mistake.
Here is patch updated to distinguish ARM and Thumb2.
Tested for Thumb1, Thumb2 and ARM modes. No regression.
Is it OK?

Hi Richard,
Is it ok to apply this fix to gcc 4.7 branch?
BR,
Terry

This causes the arm.exp testcase to fail with a tcl error for me:
ERROR: tcl error sourcing /home/uweigand/fsf/gcc-head/gcc/testsuite/gcc.target/arm/arm.exp.
ERROR: unmatched open brace in list
while executing

which seems to be caused by a missing space between two closing braces.
Fixed by the following patch.
Committed to mainline as obvious.
Bye,
Ulrich

* gcc.target/arm/combine-movs.c: Add missing space.
