gold: x86-64: Fix TLSDESC -> LE relaxation X86-64 TLSDESC sequences can be: 4c 8d 0d 00 00 00 00 leaq foo@TLSDESC(%rip), %r9 4c 89 c8 movq %r9, %rax ff 10 call *foo@TLSCALL(%rax) TLSDESC -> LE relaxation can turn them into: 49 c7 c1 fc ff ff ff mov $0xfffffffffffffffc,%r9 4c 89 c8 mov %r9,%rax 66 90 xchg %ax,%ax We need to check and update the REX byte in this case. PR gold/25473 * x86_64.cc (Target_x86_64<size>::Relocate::tls_desc_gd_to_ie): Properly check r8 - r15 in "lea foo@TLSDESC(%rip), %reg".

# x86_64_gd_to_ie.sh -- a test for GDesc -> IE conversion.
Update year range in copyright notice of binutils files 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.
