The newer update-copyright.py fixes file encoding too, removing cr/lf
on binutils/bfdtest2.c and ld/testsuite/ld-cygwin/exe-export.exp, and
embedded cr in binutils/testsuite/binutils-all/ar.exp string match.
The result of running etc/update-copyright.py --this-year, fixing all
the files whose mode is changed by the script, plus a build with
--enable-maintainer-mode --enable-cgen-maint=yes, then checking
out */po/*.pot which we don't update frequently.
The copy of cgen was with commit d1dd5fcc38ead reverted as that commit
breaks building of bfp opcodes files.
The patch also fixes a case where libopcodes built for a 64-bit
bfd_vma may print different results to libopcodes built for a 32-bit
bfd_vma.
* tic4x-dis.c (tic4x_dp): Make unsigned.
tic4x uses a number of static variables for tables that are generated
depending on the current machine (tic4x vs. tic3x). However, it is
possible to change the machine from one invocation of print_insn_tic4x
to the next. This patch throws away the old state if that happens,
and uses a relatively small known size array of register names rather
than a malloc'd table.
* tic4x-dis.c (tic4x_version): Make unsigned long.
(optab, optab_special, registernames): New file scope vars.
(tic4x_print_register): Set up registernames rather than
malloc'd registertable.
(tic4x_disassemble): Delete optable and optable_special. Use
optab and optab_special instead. Throw away old optab,
optab_special and registernames when info->mach changes.
Don't do that. Especially don't use shift counts that assume the type
being shifted is 32 bits when the type is long/unsigned long. Also
reverts part of a change I made on 2019-12-11 to tic4x_print_register
that on closer inspection turns out to be unnecessary.
include/
* opcode/tic4x.h (EXTR): Delete.
(EXTRU, EXTRS, INSERTU, INSERTS): Rewrite without zero/sign
extension using shifts. Do trim INSERTU value to specified bitfield.

* tic4x-dis.c (tic4x_print_register): Remove dead code.

parameters. Added support for new opcode-list format. General
error message fixups.
(c4x_inst_add): Reject insn not for our CPU
(md_begin): Added matrix for setting the proper opcode-level &
device-flags according to cpu type and revision. Rewrite the
opcode hasher.
(c4x_operand_parse): Fix opcode bug
(c4x_operands_match): New function argument. Added dry-run
mechanism, that is optional error generation. Added constraint 'i'
and 'j'.
(c4x_insn_check): Added new function for post-verification of the
generated insn.
(md_assemble): Check all opcodes before croaking because of an
argument mismatch. Need this to be able to fully support
ortogonally arguments.
(md_parse_options): Revised commandprompt swicthes and added new
ones.
(md_show_usage): Complete rewrite of printout.

instruction classes, and put each instruction into a class.
