readelf: Restore a lost new line in version information Fix a commit 74e1a04b9787 ("More fixes for reading corrupt ELF files.") `readelf --version-info' output formatting regression where a dropped new line caused section header information from the `.gnu.version_d' version definition section to be printed on the same line as this section's first entry. For example with the `mips-linux' target we get: $ cat ver_def.s .data .globl new_foo .type new_foo, %object new_foo: .symver new_foo, foo@@ver_foo $ cat ver_def.ver { global: *foo*; local: *; }; $ as -o ver_def.o ver_def.s $ ld -e 0 --export-dynamic --version-script=ver_def.ver -o ver_def ver_def.o $ readelf -V ver_def Version symbols section '.gnu.version' contains 4 entries: Addr: 000000000000007e Offset: 0x01007e Link: 2 (.dynsym) 000: 0 (*local*) 2 (ver_foo) 1 (*global*) 2 (ver_foo) Version definition section '.gnu.version_d' contains 2 entries: Addr: 0x0000000000000088 Offset: 0x010088 Link: 3 (.dynstr) 000000: Rev: 1 Flags: BASE Index: 1 Cnt: 1 Name: ver_def 0x001c: Rev: 1 Flags: none Index: 2 Cnt: 1 Name: ver_foo Version definition past end of section $ Add the new line then, to get: $ readelf -V ver_def Version symbols section '.gnu.version' contains 4 entries: Addr: 000000000000007e Offset: 0x01007e Link: 2 (.dynsym) 000: 0 (*local*) 2 (ver_foo) 1 (*global*) 2 (ver_foo) Version definition section '.gnu.version_d' contains 2 entries: Addr: 0x0000000000000088 Offset: 0x010088 Link: 3 (.dynstr) 000000: Rev: 1 Flags: BASE Index: 1 Cnt: 1 Name: ver_def 0x001c: Rev: 1 Flags: none Index: 2 Cnt: 1 Name: ver_foo Version definition past end of section $ instead. binutils/ * readelf.c (process_version_sections) <SHT_GNU_verdef>: Print a new line between the heading and the first version definition entry.

objdump: Better objdump section headers in wide mode When displaying the section headers table using objdump (-h), the column containing the section header name is currently fixed at 13 characters. A section name that is longer than 13 characters will overflow the column causing the table to become miss-aligned. In this commit I change the behaviour so that _in wide mode_ (-w -h) the section name column is dynamically resized to fit the longest section name we plan to display. In wide mode the column still retains a minimum width of 13 characters. In non-wide more the behaviour is completely unchanged. While I was changing the dump_headers function I have unified the two printf lines that handled the different address widths into a single printf, the address width is now passed into printf using the '*' field width format character. binutils/ChangeLog: * objdump.c (dump_section_header): Extract max section name length from data parameter, use this when formatting output. (find_longest_section_name): New function. (dump_headers): Calculate longest section name when in wide mode, reformat to unify printing of header line. ld/ChangeLog: * testsuite/ld-elf/eh-frame-hdr.d: Update expected results.
