From 0eb5be2edd39918b1a182e8fb2629d6db1527033 Mon Sep 17 00:00:00 2001 From: obrien Date: Mon, 28 May 2001 05:49:34 +0000 Subject: Merge our ELF branding into Binutils 2.11[.0]. I have also turned off the older 100% against-the-gABI method[*]. If you must really have it, define "WANT_OLD_BRANDELF_METHOD". [*] but left the stretching the gABI method until I finish writing the notes section support in the ELF image loader. --- contrib/binutils/bfd/elf.c | 1047 ++++++++++++++++++++++++++++---------------- 1 file changed, 667 insertions(+), 380 deletions(-) (limited to 'contrib/binutils') diff --git a/contrib/binutils/bfd/elf.c b/contrib/binutils/bfd/elf.c index be88fa4..8910820 100644 --- a/contrib/binutils/bfd/elf.c +++ b/contrib/binutils/bfd/elf.c @@ -33,6 +33,8 @@ SECTION haven't bothered yet. */ +/* For sparc64-cross-sparc32. */ +#define _SYSCALL32 #include "bfd.h" #include "sysdep.h" #include "bfdlink.h" @@ -229,11 +231,11 @@ bfd_elf_hash (namearg) /* Read a specified number of bytes at a specified offset in an ELF file, into a newly allocated buffer, and return a pointer to the - buffer. */ + buffer. */ static char * elf_read (abfd, offset, size) - bfd * abfd; + bfd *abfd; long offset; unsigned int size; { @@ -254,31 +256,31 @@ elf_read (abfd, offset, size) boolean bfd_elf_mkobject (abfd) - bfd * abfd; + bfd *abfd; { - /* this just does initialization */ - /* coff_mkobject zalloc's space for tdata.coff_obj_data ... */ + /* This just does initialization. */ + /* coff_mkobject zalloc's space for tdata.coff_obj_data ... */ elf_tdata (abfd) = (struct elf_obj_tdata *) bfd_zalloc (abfd, sizeof (struct elf_obj_tdata)); if (elf_tdata (abfd) == 0) return false; - /* since everything is done at close time, do we need any - initialization? */ + /* Since everything is done at close time, do we need any + initialization? */ return true; } boolean bfd_elf_mkcorefile (abfd) - bfd * abfd; + bfd *abfd; { - /* I think this can be done just like an object file. */ + /* I think this can be done just like an object file. */ return bfd_elf_mkobject (abfd); } char * bfd_elf_get_str_section (abfd, shindex) - bfd * abfd; + bfd *abfd; unsigned int shindex; { Elf_Internal_Shdr **i_shdrp; @@ -293,7 +295,7 @@ bfd_elf_get_str_section (abfd, shindex) shstrtab = (char *) i_shdrp[shindex]->contents; if (shstrtab == NULL) { - /* No cached one, attempt to read, and cache what we read. */ + /* No cached one, attempt to read, and cache what we read. */ offset = i_shdrp[shindex]->sh_offset; shstrtabsize = i_shdrp[shindex]->sh_size; shstrtab = elf_read (abfd, offset, shstrtabsize); @@ -304,7 +306,7 @@ bfd_elf_get_str_section (abfd, shindex) char * bfd_elf_string_from_elf_section (abfd, shindex, strindex) - bfd * abfd; + bfd *abfd; unsigned int shindex; unsigned int strindex; { @@ -345,6 +347,7 @@ _bfd_elf_make_section_from_shdr (abfd, hdr, name) { asection *newsect; flagword flags; + struct elf_backend_data *bed; if (hdr->bfd_section != NULL) { @@ -383,10 +386,23 @@ _bfd_elf_make_section_from_shdr (abfd, hdr, name) /* The debugging sections appear to be recognized only by name, not any sort of flag. */ - if (strncmp (name, ".debug", sizeof ".debug" - 1) == 0 - || strncmp (name, ".line", sizeof ".line" - 1) == 0 - || strncmp (name, ".stab", sizeof ".stab" - 1) == 0) - flags |= SEC_DEBUGGING; + { + static const char *debug_sec_names [] = + { + ".debug", + ".gnu.linkonce.wi.", + ".line", + ".stab" + }; + int i; + + for (i = sizeof (debug_sec_names) / sizeof (debug_sec_names[0]); i--;) + if (strncmp (name, debug_sec_names[i], strlen (debug_sec_names[i])) == 0) + break; + + if (i >= 0) + flags |= SEC_DEBUGGING; + } /* As a GNU extension, if the name begins with .gnu.linkonce, we only link a single copy of the section.
