--- Comment #22 from Georg-Johann Lay <gjl at gcc dot gnu.org> ---
I allowed me to add some test cases. Unfortunatels, one of them is failing
with the patch and -mlra, whereas is passes with -mno-lra.
In $builddir/gcc:
$ make -k check-gcc RUNTESTFLAGS="--target_board=atmega128-sim
--tool_opts='-mlra' avr-torture.exp=lra-pr116550-2.c"
[...]
Running
/home/john/xgnu/source/gcc-master/gcc/testsuite/gcc.target/avr/torture/avr-torture.exp
...
FAIL: gcc.target/avr/torture/lra-pr116550-2.c -O1 execution test
=== gcc Summary ===
