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.
The Emacs 28 compiler warns about dwarf-mode.el:
Warning (comp): dwarf-mode.el:180:32: Warning: Unused lexical argument `ignore'
This is easily fixed by prepending "_" to the parameter's name.
binutils/ChangeLog
2022-12-19 Tom Tromey <tromey@adacore.com>
* dwarf-mode.el (dwarf-do-refresh): Avoid compiler warning.
PR 29914
* dwarf.c (fetch_indexed_value): Fail if the section is not big
enough to contain a header size field.
(display_debug_addr): Fail if the computed address size is too big
or too small.
PR 25202
bfd * bfd.c (VerilogDataEndianness): New variable.
(verilog_write_record): Use VerilogDataEndianness, if set, to
choose the endianness of the output.
(verilog_write_section): Adjust the address by the data width.
binutils* objcopy.c (copy_object): Set VerilogDataEndianness to the
endianness of the input file.
(copy_main): Verifiy the value set by the --verilog-data-width
option.
* testsuite/binutils-all/objcopy.exp: Add tests of the new behaviour.
* testsuite/binutils-all/verilog-I4.hex: New file.
PR 29764
gas * testsuite/gas/arm/cpu-cortex-a76ae.d: Add arm prefix to the -m
option passed to objdump.
* testsuite/gas/arm/cpu-cortex-a77.d: Likewise.
* testsuite/gas/aarch64/cpu-cortex-a76ae.d: Add aarch64 prefix to
the -m option passed to objdump.
* testsuite/gas/aarch64/cpu-cortex-a77.d: Likewise.
bfd * cpu-arm.c (scan): Accept machine names prefixed with "arm:".
* cpu-aarch64.c (scan): Accept machine names prefixed with "aarch64:".
bin * doc/binutils.texi (objdump): Note that the -m option supports
the <architecture>:<machine> syntax.
Add with_source_code to the command line options that trigger
might_need_separate_debug_info and dump_any_debugging. This helps
'objdump -S' download missing files via debuginfod without the need for
specifying extra command line options like '-L'.
PR 29532
bfd * elf.c (setup_group): Do not return false if there is no group
information available.
bionutils* objcopy.c (setup_section): Leave group sections intact when
creating separate debuginfo files.
Currently objdump -S is not able to make use files downloaded from debuginfod.
This is due to bfd_find_nearest_line_discriminator being unable to locate any
separate debuginfo files in the debuginfod cache. Additionally objdump lacked
a call to debuginfod_find_source in order to download missing source files.
Fix this by using bfd_find_nearest_line_with_alt instead of
bfd_find_nearest_line_discriminator. Also add a call to
debuginfod_find_source in order to download missing source files.
