From d1c4b12b9d48d9266b78e2c22d70aa25830b9f8f Mon Sep 17 00:00:00 2001 From: Nick Clifton Date: Fri, 15 May 2015 11:21:38 +0100 Subject: Fix PR18374 by making readelf and objdump ignore end-of-list markers in the .debug_loc section if there are relocations against them. PR binutils/18374 bin * dwarf.h (struct dwarf_section): Add reloc_info and num_relocs fields. (struct dwarf_section_display): Change bitfield to boolean. (reloc_at): Add prototype. * dwarf.c (display_loc_list): Ignore list terminators if there are relocs against them. (display_debug_loc): Issue a warning if there are relocs against the .debug_loc section. (display_displays): Initialise reloc_info and num_relocs fields. * objdump.c (load_specific_debug_section): Initialise reloc_info and num_relocs fields. (reloc_at): New function. * readelf.c (is_32bit_abs_reloc): Add IA64's R_IA64_DIS32LSB reloc. (reloc_at): New function. (apply_relocations): Add relocs_return and num_relocs_return parameters. Fill them in with the loaded relocs if non-NULL. (dump_section_as_bytes): Update call to apply_relocations. (load_specific_debug_section): Initialise reloc_info and num_relocs fields. tests * binutils-all/pr18374.s: New test file. * binutils-all/readelf.exp: Assemble and run the new test. * binutils-all/readelf.pr18374: Expected output from readelf. --- binutils/dwarf.h | 12 +++++++++++- 1 file changed, 11 insertions(+), 1 deletion(-) (limited to 'binutils/dwarf.h') diff --git a/binutils/dwarf.h b/binutils/dwarf.h index 0e661d4..e679320 100644 --- a/binutils/dwarf.h +++ b/binutils/dwarf.h @@ -124,6 +124,11 @@ struct dwarf_section dwarf_vma address; dwarf_size_type size; enum dwarf_section_display_enum abbrev_sec; + + /* Used by clients to help them implement the reloc_at callback. */ + void * reloc_info; + unsigned long num_relocs; + /* A spare field for random use. */ void *user_data; }; @@ -135,7 +140,7 @@ struct dwarf_section_display struct dwarf_section section; int (*display) (struct dwarf_section *, void *); int *enabled; - unsigned int relocate : 1; + bfd_boolean relocate; }; extern struct dwarf_section_display debug_displays []; @@ -217,3 +222,8 @@ extern void * xcmalloc (size_t, size_t); extern void * xcrealloc (void *, size_t, size_t); extern dwarf_vma read_leb128 (unsigned char *, unsigned int *, bfd_boolean, const unsigned char * const); + +/* A callback into the client.
