Subject: * cgen asm/disasm

[opcodes/ChangeLog]
2001-05-07  Frank Ch. Eigler  <fche@redhat.com>

        * cgen-dis.in (default_print_insn): Tolerate min<base instructions
        even at end of a section.
        * cgen-ibld.in (extract_normal): Tolerate min!=base!=max instructions
        by ignoring precariously-unpacked insn_value in favor of raw buffer.

[cgen/ChangeLog]
2001-05-07  Frank Ch. Eigler  <fche@redhat.com>

        * iformat.scm (compute-insn-base-mask-length): Rewrite to tolerate
        various-base-length instruction sets.
