(_bfd_elf32_bfd_from_remote_memory, _bfd_elf64_bfd_from_remote_memory): Declare them. * elfxx-target.h (elf_backend_bfd_from_remote_memory): New macro. (elfNN_bed): Add that to the initializer. 2003-05-15 Roland McGrath * elf.c (elfcore_grok_note): Grok NT_AUXV note, make ".auxv" section. --- bfd/elf.c | 38 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 38 insertions(+) diff --git a/bfd/elf.c b/bfd/elf.c index fa4416d0b6..5e72eb05bf 100644 --- a/bfd/elf.c +++ b/bfd/elf.c @@ -6884,6 +6884,20 @@ elfcore_grok_note (abfd, note) #else return TRUE; #endif + + case NT_AUXV: + { + asection *sect = bfd_make_section (abfd, ".auxv"); + + if (sect == NULL) + return FALSE; + sect->_raw_size = note->descsz; + sect->filepos = note->descpos; + sect->flags = SEC_HAS_CONTENTS; + sect->alignment_power = 1 + bfd_get_arch_size (abfd) / 32; + + return TRUE; + } } } @@ -7535,3 +7549,27 @@ _bfd_elf_section_offset (abfd, info, sec, offset) return offset; } } + +/* Create a new BFD as if by bfd_openr.
