2023-12-04Fix two buglets in .debug_names dumpingTom Tromey1-0/+5
While working on gdb's .debug_names writer, I found a couple of small bugs in binutils .debug_names dumping. First, the DWARF spec (section 6.1.1.4.6 Name Table) says: These two arrays are indexed starting at 1, [...] I think it is clearer for binutils to follow this, particularly because DW_IDX_parent refers to this number. Second, I think the handling of an empty hash table is slightly wrong. Currently the dumping code assumes there is always an array of hashes. However, section 6.1.1.4.5 Hash Lookup Table says: The optional hash lookup table immediately follows the list of type signatures. and then: The hash lookup table is actually two separate arrays: an array of buckets, followed immediately by an array of hashes. My reading of this is that the hash table as a whole is optional, and so the hashes will not exist in this case. (This also makes sense because the hashes are not useful without the buckets anyway.) This patch fixes both of these problems. FWIW I have some gdb patches in progress that change gdb both to omit the hash table and to use DW_IDX_parent. 2023-12-04 Tom Tromey <tom@tromey.com> * dwarf.c (display_debug_names): Handle empty .debug_names hash table. Name entries start at 1.

When compiling hello world and adding a v9 .gdb-index section: ... $ gcc -g hello.c $ gdb-add-index a.out ... readelf shows it as: ... Shortcut table: Language of main: unknown: 0 Name of main: ^A ... The documentation of gdb says about the "Name of main" that: ... This value must be ignored if the value for the language of main is zero. ... Implement this approach in display_gdb_index, such that we have instead: ...

2023-07-30bpf: include, bfd, opcodes: add EF_BPF_CPUVER ELF header flagsJose E. Marchesi1-0/+5
This patch adds support for EF_BPF_CPUVER bits in the ELF machine-dependent header flags. These bits encode the BPF CPU version for which the object file has been compiled for. The BPF assembler is updated so it annotates the object files it generates with these bits. The BPF disassembler is updated so it honors EF_BPF_CPUVER to use the appropriate ISA version if the user didn't specify an explicit ISA version in the command line. Note that a value of zero in EF_BPF_CPUVER is interpreted by the disassembler as "use the later supported version" (the BPF CPU versions start with v1.) The readelf utility is updated to pretty print EF_BPF_CPUVER when it prints out the ELF header: $ readelf -h a.out ELF Header: ... Flags: 0x4, CPU Version: 4 Tested in bpf-unknown-none. include/ChangeLog: 2023-07-30 Jose E.

2023-02-09Add full display feature to dwarf-mode.elTom Tromey1-0/+8
I've found that I often use dwarf-mode with relatively small test files. In this situation, it's handy to be able to expand all the DWARF, rather than moving to each "..." separately and using C-u C-m. This patch implements this feature. It also makes a couple of other minor changes: * I removed a stale FIXME from dwarf-mode. In practice I find I often use "g" to restore the buffer to a pristine state; checking the file mtime would work against this. * I tightened the regexp in dwarf-insert-substructure. This prevents the C-m binding from trying to re-read a DIE which has already been expanded. * Finally, I've bumped the dwarf-mode version number so that this version can easily be installed using package.el. 2023-02-09 Tom Tromey <tromey@adacore.com> * dwarf-mode.el: Bump version to 1.8.
