From 1ce53adf13a54375d2a5c7cdbe341b2558389615 Mon Sep 17 00:00:00 2001 From: Denys Vlasenko Date: Thu, 29 Jul 2010 01:47:53 +0200 Subject: modpost: support objects with more than 64k sections This patch makes modpost able to process object files with more than 64k sections. Needed for huge kernel builds (allyesconfig, for example) with -ffunction-sections. 64k sections handling is covered, for example, by this document: "IA-64 gABI Proposal 74: Section Indexes" http://www.codesourcery.com/public/cxx-abi/abi/prop-74-sindex.html Signed-off-by: Denys Vlasenko Signed-off-by: Anders Kaseorg Acked-by: Sam Ravnborg Cc: Rusty Russell Cc: Andi Kleen Signed-off-by: Michal Marek --- scripts/mod/file2alias.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'scripts/mod/file2alias.c') diff --git a/scripts/mod/file2alias.c b/scripts/mod/file2alias.c index 220213e..33f4363 100644 --- a/scripts/mod/file2alias.c +++ b/scripts/mod/file2alias.c @@ -839,16 +839,16 @@ void handle_moddevtable(struct module *mod, struct elf_info *info, char *zeros = NULL; /* We're looking for a section relative symbol */ - if (!sym->st_shndx || sym->st_shndx >= info->hdr->e_shnum) + if (!sym->st_shndx || get_secindex(info, sym) >= info->num_sections) return; /* Handle all-NULL symbols allocated into .bss */ - if (info->sechdrs[sym->st_shndx].sh_type & SHT_NOBITS) { + if (info->sechdrs[get_secindex(info, sym)].sh_type & SHT_NOBITS) { zeros = calloc(1, sym->st_size); symval = zeros; } else { symval = (void *)info->hdr - + info->sechdrs[sym->st_shndx].sh_offset + + info->sechdrs[get_secindex(info, sym)].sh_offset + sym->st_value; } -- cgit v1.1
