Add sh2e support: 

2002-08-12  Alexandre Oliva  <aoliva@redhat.com>

        * config/sh/sh.c (output_branch) [TARGET_SH2E]: Handle
        med_cbranches.  Fix logic in short_cbranches.

    2002-04-03  Alexandre Oliva  <aoliva@redhat.com>

        * config/sh/sh.md (delay for cbranch): Don't annul delay
        slots on SH2e.
        * config/sh/sh.c (sh_insn_length_adjustment): Add 2 for
        cbranch with unfilled delay slot on SH2e.
        (output_branch): Fill with a nop the delay slot of a
        branch that required a delay slot but didn't get one.

    2002-04-02  Alexandre Oliva  <aoliva@redhat.com>

        * doc/invoke.texi (SH options): Document -m2e.
        * config/sh/crt1.asm: Add __SH2E__ Next to __SH3E__.
        * config/sh/lib1funcs.asm: Likewise.
        * config/sh/sh.c: Replace all uses of TARGET_SH3E with SH2E.
        * config/sh/sh.h (CPP_SPEC): Define __SH2E__ for -m2e, and
        not __sh1__.
        (CONDITIONAL_REGISTER_USAGE): Don't disable FP regs from
        SH2E up.
        (SH3E_BIT): Renamed to...
        (SH_E_BIT): ... this.  Replace all uses.
        (TARGET_SH2E): Define from SH_E_BIT and TARGET_SH2.
        Replace all uses of TARGET_SH3E with TARGET_SH2E.
        (TARGET_SWITCHES): Added 2e.
        (OVERRIDE_OPTIONS): Set sh_cpu for SH2E.
        (processor_type): Added PROCESSOR_SH2E.
        * config/sh/sh.md: Replace all uses of TARGET_SH3E with
        TARGET_SH2E, except in sqrtsf2_i.
        (attribute cpu): Added sh2e.
        * config/sh/t-sh (MULTILIB_OPTIONS): Replace m3e with m2e.
        (MULTILIB_MATCHES): Use m2e multilib for m3e.
        * config.gcc: Add sh2e target support.
