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 bit_fix was implemented to support machines that need variables
|
|
to be inserted in bitfields other than 1, 2 and 4 bytes.
|
|
Furthermore it gives us a possibility to mask in bits in the symbol
|
|
when it's fixed in the object code and check the symbols limits.
|
|
|
|
The or-mask is used to set the huffman bits in displacements for the
|
|
ns32k port.
|
|
The acbi, addqi, movqi, cmpqi instruction requires an assembler that
|
|
can handle bitfields. Ie. handle an expression, evaluate it and insert
|
|
the result in some bitfield. (eg: 5 bits in a short field of an opcode). */
