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.
* cgen-asm.in: Include "xregex.h" always to enable the libiberty
regex support.
(@arch@_cgen_build_insn_regex): New routine from Graydon.
(@arch@_cgen_assemble_insn): Add Graydon's code to use regex
to verify if it is worth parsing the insn as insn "x". Also update
error message when insn is not a recognized format of the insn vs
when the insn is completely unrecognized.
* cgen-asm.in (@arch@_cgen_assemble_insn): Move tmp_errmsg
declaration inside CGEN_VERBOSE_ASSEMBLER_ERRORS conditional.
* cgen-ibld.in (put_insn_int_value): Mark cd parameter as unused
to allay a compiler warning.
* cgen-asm.in (parse_insn_normal): Changed syn to be
CGEN_SYNTAX_CHAR_TYPE. Changed all references to *syn
as character to use CGEN_SYNTAX_CHAR macro and all comparisons
to '\0' to use 0 instead.
* cgen-dis.in (print_insn_normal): Ditto.
* cgen-ibld.in (insert_insn_normal, extract_insn_normal): Ditto.
