* All CGEN-generated sources: Regenerate.
Contribute the following changes:
2005-09-19 Dave Brolley <brolley@redhat.com>
* disassemble.c (disassemble_init_for_target): Add 'break' to case for
bfd_arch_tic4x. Use cgen_bitset_create and cgen_bitset_set for
bfd_arch_m32c case.
2005-02-16 Dave Brolley <brolley@redhat.com>
* cgen-dis.in: Rename CGEN_ISA_MASK to CGEN_BITSET. Rename
cgen_isa_mask_* to cgen_bitset_*.
* cgen-opc.c: Likewise.
2003-11-28 Richard Sandiford <rsandifo@redhat.com>
* cgen-dis.in (print_insn_@arch@): Fix comparison with cached isas.
* *-dis.c: Regenerate.
2003-06-05 DJ Delorie <dj@redhat.com>
* cgen-dis.in (print_insn_@arch@): Copy prev_isas, don't assign
it, as it may point to a reused buffer. Set prev_isas when we
change cpus.
2002-12-13 Dave Brolley <brolley@redhat.com>
* cgen-opc.c (cgen_isa_mask_create): New support function for
CGEN_ISA_MASK.
(cgen_isa_mask_init): Ditto.
(cgen_isa_mask_clear): Ditto.
(cgen_isa_mask_add): Ditto.
(cgen_isa_mask_set): Ditto.
(cgen_isa_supported): Ditto.
(cgen_isa_mask_compare): Ditto.
(cgen_isa_mask_intersection): Ditto.
(cgen_isa_mask_copy): Ditto.
(cgen_isa_mask_combine): Ditto.
* cgen-dis.in (libiberty.h): #include it.
(isas): Renamed from 'isa' and now (CGEN_ISA_MASK *).
(print_insn_@arch@): Use CGEN_ISA_MASK and support functions.
* Makefile.am (CGENDEPS): Add utils-cgen.scm and attrs.scm.
* Makefile.in: Regenerated.
