* some support for funny-endian 16/32-bit insn sets
[cgen/ChangeLog]
2001-07-11 Frank Ch. Eigler <fche@redhat.com>
* desc-cpu.scm (-gen-mach-table-defns): Emit fourth field: the
mach->cpu insn-chunk-bitsize.
(-gen-cpu-open): In @arch@_cgen_rebuild_tables, process above new
field toward CGEN_CPU_TABLE->insn_chunk_bitsize.
* mach.scm (<cpu>): New field insn-chunk-bitsize.
(-cpu-parse, -cpu-read): Parse/initialize it.
* doc/rtl.texi (define-cpu): Document it.
[opcodes/ChangeLog]
2001-07-11 Frank Ch. Eigler <fche@redhat.com>
* cgen-dis.in (print_insn): Use cgen_get_insn_value instead of
bfd_get_bits.
* cgen-opc.c (cgen_get_insn_value, cgen_put_insn_value): Respect
non-zero CGEN_CPU_DESC->insn_chunk_bitsize.
[include/opcode/ChangeLog]
2001-07-11 Frank Ch. Eigler <fche@redhat.com>
* cgen.h (CGEN_MACH): Add insn_chunk_bitsize field.
(cgen_cpu_desc): Ditto.
