According to the description of the state machine, the expectation
appears to be that (leaving aside labels) any insn mnemonic or
directive would be followed by a comma separated list of operands. That
may have been true very long ago, but the latest with the advent of more
elaborate macros this isn't rhe case anymore. Neither macro parameters
in macro definitions nor macro arguments in macro invocations are
required to be separated by commas. Hence whitespace serves a crucial
role there. Plus even without "real" macros issues exist, in e.g.
.irp n, ...
insn\n\(suffix) operand1, operand2
.endr
Whitespace following the closing parenthesis would have been removed
(ahead of even processing the .irp), as the "opcode" was deemed to have
ended earlier already.
Therefore, squash the distinction between "opcode" and operands, i.e.
fold state 10 back into state 3. Also drop most of the distinction
between "symbol chars" and "relatively normal" ones. Not entirely
unexpectedly this results in the need to skip whitespace in a few more
places in arch-specific code (and quite likely more changes are needed
for insn forms not covered by the testsuite).
As a result the D10V special case is no longer necessary.
In config/tc-sparc.c also move a comment to be next to the code being
commented.
In opcodes/cgen-asm.in some further cleanup is done, following the local
var adjustments.
Adds two new external authors to etc/update-copyright.py to cover
bfd/ax_tls.m4, and adds gprofng to dirs handled automatically, then
updates copyright messages as follows:
1) Update cgen/utils.scm emitted copyrights.
2) Run "etc/update-copyright.py --this-year" with an extra external
author I haven't committed, 'Kalray SA.', to cover gas testsuite
files (which should have their copyright message removed).
3) Build with --enable-maintainer-mode --enable-cgen-maint=yes.
4) Check out */po/*.pot which we don't update frequently.
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.
