Hi,
The attached patch fixes the gcc.target/sh/fpchg.c test case. The test
case actually never worked since it requires at least -O option to
output the expected fpchg insn. Moreover, scan-assembler "fpchg" would
match on the file name string in the asm output. Fixed and tested with
make check-gcc RUNTESTFLAGS="sh.exp=pr53513-1.c --target_board=sh-sim
\{-m4a/-ml,-m4a/-mb,-m4a-single/-ml,-m4a-single/-mb,-m4a-nofpu/-ml,-m4a-nofpu/-mb}".
Commited as r218793.
Cheers,
Oleg
