yann@1: + * Reporter: shrinivasa@kpitcummins.com 
yann@1: + * Summary: Renesas SH - Incorrect code generation
yann@1: + * Description:
yann@1: + * When following code is compiled  with
yann@1: + * sh-elf-gcc  -S -mhitachi -m2 -O2 bug1.c
yann@1: + * generates an incorrect code.
yann@1: + *
yann@1: + * Testcase tweaked by dank@kegel.com
yann@1: + * Problem only happens with -mhitachi -m2.  Not sure if I can give those
yann@1: + * options for all sh targets.  They work on sh4, though.
yann@1: + * Not marked as xfail as it's a regression relative to hardhat 2.0 gcc-2.97.
