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.
While the patch already committed for pr30793 prevents the asan error,
there is a problem: Now the last element of bundle_words never gets
written. That's very likely wrong, or KVXMAXBUNDLEWORDS is too big.
So this patch rearranges things a little to support writing of all of
bundle_words and does the parallel bit checking only when filling
bundle_words. In the normal case, kvx_reassemble_bundle will see
bundle_words[word_count-1] with the parallel bit clear and all other
words having it set. In the error case where all words in
bundle_words have the parallel bit set, kvx_reassemble_bundle will be
passed a wordcount of KVXMAXBUNDLEWORDS + 1. I've also made
kvx_reassemble_bundle return true for success rather than zero, and
removed the unnecessary check for zero wordcount.
PR 30793
* kvx-dis.c (kvx_reassemble_bundle): Return bool, true on success.
Fail if wordcount is too large. Don't check for wordcount zero.
Don't check kvx_has_parallel_bit.
(print_insn_kvx): Rewrite code reading bundle_words as a for loop.
Don't stop reading at KVXMAXBUNDLEWORDS - 1.
(decode_prologue_epilogue_bundle): Similarly.
opcodes/
* kvx-dis.c (print_insn_kvx): Change the loop condition so that
wordcount is always less than KVXMAXBUNDLEWORDS.
(decode_prologue_epilogue_bundle): Likewise.
kvx_dis_init currently always returns true, but error conditions do so
by "return -1" which converts to true. The return status is ignored
anyway, and it doesn't make much sense to error on unexpected arch or
mach: If print_insn_kvx is called then the atch is known to be kvx,
and it's better to choose some default for a user passing an unknown
mach value rather than segfaulting in decode_insn when env.opc_table
is NULL.
I've chosen the default mach to be bfd_mach_kv3_1, the default in
bfd/cpu-kvx.c, not that it matters very much. In normal objdump/gdb
usage, info->mach won't be an unexpected value.
* kvx-dis.c (kvx_dis_init): Return void. Don't error on
unexpected arch or mach. Default to bfd_mach_kv3_1 for
unknown mach. Don't clear info->disassembler_options.
