2024-01-04Update year range in copyright notice of binutils filesAlan Modra1-1/+1
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.
2023-11-08gas: S_GET_{NAME,SEGMENT}() don't alter their input symbolJan Beulich1-2/+2
Make their parameters pointer-to-const, thus allowing callers to also be const-correct where possible.
2023-01-01Update year range in copyright notice of binutils filesAlan Modra1-1/+1

2022-02-16gas local label and dollar label handlingAlan Modra1-5/+5
Much of the gas source and older BFD source use "long" for function parameters and variables, when other types would be more appropriate. This patch fixes one of those cases. Dollar labels and numeric local labels do not need large numbers. Small positive itegers are usually all that is required. Due to allowing longs, it was possible for fb_label_name and dollar_label_name to overflow their buffers. * symbols.c: Delete unnecessary forward declarations.

The copy of cgen was with commit d1dd5fcc38ead reverted as that commit breaks building of bfp opcodes files.

2018-10-29Move struc-symbol.h to symbols.cAlan Modra1-0/+3
This file was never supposed to be widely used. The fact that it has found its way into many gas files led to bugs, typically when code expecting a symbolS* to point at a struct symbol is presented with a struct local_symbol.

2005-10-11This adjusts equate handling byNick Clifton1-0/+9
- allowing true forward references (which will always assume the referenced symbols have at the point of use) through the new .eqv pseudo-op and the new == operator - disallowing changing .equiv-generated equates (so that the protection this provides is both forward and backward) - snapshotting equates when their value gets changed so that previous uses don't get affected by the new value. - allowing expressions in places where absolute expressions (or register names) are needed which were not completely resolvable at the point of their definition but which are fully resolvable at the point of use In addition it fixes PR/288.
