 +/* PR target/10412

 + * Reporter: shrinivasa@kpitcummins.com 

 + * Summary: Renesas SH - Incorrect code generation

 + * Description:

 + * When following code is compiled  with

 + * sh-elf-gcc  -S -mhitachi -m2 -O2 bug1.c

 + * generates an incorrect code.

 + *

 + * Testcase tweaked by dank@kegel.com

 + * Problem only happens with -mhitachi -m2.  Not sure if I can give those

 + * options for all sh targets.  They work on sh4, though.

 + * Not marked as xfail as it's a regression relative to hardhat 2.0 gcc-2.97.
