re PR target/50694 (SH Target: SH2A little endian does not actually work)
PR target/50694
* config/sh/sh.h (IS_LITTLE_ENDIAN_OPTION, UNSUPPORTED_SH2A):
New macros.
(DRIVER_SELF_SPECS): Use new macros to filter out
unsupported options taking the default configuration into
account.
* gcc.target/sh/pr21255-2-ml.c: Skip if -mb or -m5* is
specified. Remove redundant runtime checks.
* gcc.target/sh/20080410-1.c: Skip if -mb is specified.
Allow for other than -m4. Fix typos in comments.
