From dc810e3900d47ab2eea86d50231ff2e70b596847 Mon Sep 17 00:00:00 2001 From: Alan Modra Date: Tue, 18 Sep 2001 09:57:26 +0000 Subject: Touches most files in bfd/, so likely will be blamed for everything.. o bfd_read and bfd_write lose an unnecessary param and become bfd_bread and bfd_bwrite. o bfd_*alloc now all take a bfd_size_type arg, and will error if size_t is too small. eg. 32 bit host, 64 bit bfd, verrry big files or bugs in linker scripts etc. o file_ptr becomes a bfd_signed_vma. Besides matching sizes with various other types involved in handling sections, this should make it easier for bfd to support a 64 bit off_t on 32 bit hosts that provide it. o I've made the H_GET_* and H_PUT_* macros (which invoke bfd_h_{get,put}_*) generally available. They now cast their args to bfd_vma and bfd_byte * as appropriate, which removes a swag of casts from the source. o Bug fixes to bfd_get8, aix386_core_vec, elf32_h8_relax_section, and aout-encap.c. o Zillions of formatting and -Wconversion fixes. --- bfd/elf64-x86-64.c | 50 +++++++++++++++++++++++++++----------------------- 1 file changed, 27 insertions(+), 23 deletions(-) (limited to 'bfd/elf64-x86-64.c') diff --git a/bfd/elf64-x86-64.c b/bfd/elf64-x86-64.c index 1605b56..24eb9f7 100644 --- a/bfd/elf64-x86-64.c +++ b/bfd/elf64-x86-64.c @@ -98,7 +98,7 @@ struct elf_reloc_map unsigned char elf_reloc_val; }; -static CONST struct elf_reloc_map x86_64_reloc_map[] = +static const struct elf_reloc_map x86_64_reloc_map[] = { { BFD_RELOC_NONE, R_X86_64_NONE, }, { BFD_RELOC_64, R_X86_64_64, }, @@ -327,9 +327,9 @@ elf64_x86_64_link_hash_table_create (abfd) bfd *abfd; { struct elf64_x86_64_link_hash_table *ret; + bfd_size_type amt = sizeof (struct elf64_x86_64_link_hash_table); - ret = ((struct elf64_x86_64_link_hash_table *) - bfd_alloc (abfd, sizeof (struct elf64_x86_64_link_hash_table))); + ret = ((struct elf64_x86_64_link_hash_table *) bfd_alloc (abfd, amt)); if (ret == (struct elf64_x86_64_link_hash_table *) NULL) return NULL; @@ -463,15 +463,16 @@ elf64_x86_64_check_relocs (abfd, info, sec, relocs) /* This is a global offset table entry for a local symbol. */ if (local_got_refcounts == NULL) { - size_t size; + bfd_size_type size; - size = symtab_hdr->sh_info * sizeof (bfd_signed_vma); + size = symtab_hdr->sh_info; + size *= sizeof (bfd_signed_vma); local_got_refcounts = ((bfd_signed_vma *) bfd_alloc (abfd, size)); if (local_got_refcounts == NULL) return false; elf_local_got_refcounts (abfd) = local_got_refcounts; - memset (local_got_refcounts, -1, size); + memset (local_got_refcounts, -1, (size_t) size); } if (local_got_refcounts[r_symndx] == -1) { @@ -606,7 +607,7 @@ elf64_x86_64_check_relocs (abfd, info, sec, relocs) if (p == NULL) { p = ((struct elf64_x86_64_pcrel_relocs_copied *) - bfd_alloc (dynobj, sizeof *p)); + bfd_alloc (dynobj, (bfd_size_type) sizeof *p)); if (p == NULL) return false; p->next = eh->pcrel_relocs_copied; @@ -1077,36 +1078,39 @@ elf64_x86_64_size_dynamic_sections (output_bfd, info) must add the entries now so that we get the correct size for the .dynamic section.
