2024-07-29PR32032 dwp segfaults on hello world binaryAlan Modra1-5/+5
Fixing the segfault is easy with this bandaid, but further work is needed to teach dwp about DW_AT_dwo_name and dwo id in the cu header. At the moment dwp only handles DW_AT_GNU_dwo_name and DW_AT_GNU_dwo_id. PR 32032 * dwp.cc (Dwp_output_file::finalize): Return immediately on no output file.
2024-01-04Update year range in copyright notice of binutils filesAlan Modra1-2/+2
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.
2023-01-01Update year range in copyright notice of binutils filesAlan Modra1-2/+2
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.
2022-01-02Update year range in copyright notice of binutils filesAlan Modra1-2/+2
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.
