2010-05-04 Roland McGrath <roland@redhat.com>
* link_map.c (dwfl_link_map_report): Detect bias of embedded phdrs and
apply it to PT_DYNAMIC p_vaddr so we handle a PIE correctly.
* core-file.c (dwfl_core_file_report): Return any nonzero count of
modules reported, even if link_map grovelling failed and only sniffing
found anything.
2010-04-26 Roland McGrath <roland@redhat.com>
* relocate.c (relocate_section): Treat R_*_NONE reloc as no reloc.
Works around probably-wrong ld -r behavior for case of a DWARF address
constant that refers to a discarded SHF_ALLOC section.
2010-04-14 Roland McGrath <roland@redhat.com>
* link_map.c (report_r_debug): Limit iterations on the l_next chain to
an upper bound on sane possible number of elements.
2010-03-11 Roland McGrath <roland@redhat.com>
* link_map.c (auxv_format_probe): Fix scanning loop, so we really scan
the second half for 32-bit matches.
2010-03-10 Roland McGrath <roland@redhat.com>
* core-file.c (dwfl_core_file_report): Punt EHDR argument.
* argp-std.c (parse_opt): Update caller.
* libdwfl.h: Declare dwfl_core_file_report.
* libdwflP.h: Don't.
2010-02-17 Roland McGrath <roland@redhat.com>
* dwfl_segment_report_module.c (addr_segndx): Take new flag argument.
If set, find the first index not below ADDR.
(dwfl_segment_report_module): Update callers.
Pass true when calculating return value.
2010-02-15 Roland McGrath <roland@redhat.com>
* Makefile.am: Use config/eu.am for common stuff.
* find-debuginfo.c (find_debuginfo_in_path): Fix uninitialized
variable in failure path.
2010-02-02 Mark Wielaard <mjw@redhat.com>
* dwfl_module_dwarf_cfi.c (dwfl_module_dwarf_cfi): Always set bias.
* dwfl_module_eh_cfi.c (dwfl_module_eh_cfi): Likewise
2010-01-07 Roland McGrath <roland@redhat.com>
* core-file.c (dwfl_core_file_report): Use elf_getphdrnum.
* dwfl_module_build_id.c (__libdwfl_find_build_id): Likewise.
