| parent | debugedit-classify-ar: Check while elf_begin loop failed or succeeded (diff) | |
Normally elf_update will do some strict checks on sections,
specifically it will check that sh_size is a multiple of sh_entsize
(if not zero). This might prevent debugedit from writing out some
sections it just wants to keep unchanged (even if they aren't strictly
valid ELF).
* tools/debugedit.c (fdopen_dso): Set elf_flagelf
ELF_F_PERMISSIVE.
