Introduce SH2a support.
2004-03-16 Corinna Vinschen <vinschen@redhat.com>
* libc/include/machine/ieeefp.h: Define _DOUBLE_IS_32BITS for
__SH2A_SINGLE_ONLY__, too.
* libc/machine/sh/asm.h: Define DELAYED_BRANCHES for __SH2A__, too.
2004-02-24 Corinna Vinschen <vinschen@redhat.com>
* libc/sys/sh/crt0.S (start_l): Support sh2a-nofpu. Fix comments.
