+/* 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.
