[libbacktrace] Add altlink field to struct dwarf_data
Add an altlink field to struct dwarf_data, and initialize it with the pointer
to the struct dwarf_data for the .gnu_debugaltlink.
2019-01-17 Tom de Vries <tdevries@suse.de>
* dwarf.c (struct dwarf_data): Add altlink field.
(backtrace_dwarf_add): Add and handle fileline_altlink parameter.
* elf.c (elf_add): Add argument to backtrace_dwarf_add call.
(phdr_callback, backtrace_initialize): Add argument to elf_add calls.
* internal.h (backtrace_dwarf_add): Add fileline_altlink parameter.
* pecoff.c (coff_add): Add argument to backtrace_dwarf_add call.
* xcoff.c (xcoff_add): Same.
