Hello,
I am attempting to use elfutils / libdw to create a library for tagging
function's local/automatic variable storage. I hope to use dwarf info to
get the stack frame offsets, etc. for function's local vars.
I started with readelf.c as an example for iterating through CU/DIE.
Since my code isn't "part of" elfutils I am not including private
headers such as libdwP.h. Because of that some of the code derived from
readelf won't compile of course.
Are these structure accesses simply short-cuts and it is possible to get
the info needed via API functions? For things like "cu->version" it
seems I can get that via the API dwarf_cu_info, but for some things I
don't quite see what I'd need in the public headers. For example, in the
(readelf.c) function get_indexed_addr, the line:
Elf_Data *debug_addr = cu->dbg->sectiondata[IDX_debug_addr];
uses the (private) structure Dwarf_CU to get at the (private) structure
Dwarf, to get at the sectiondata. I can get the Dwarf via
dwarf_cu_getdwarf, but Is there another way to get at the section data
(and IDX_debug_addr) ?
Thanks and apologies for my newbie-ness here. Please let me know if
there is a better email address to send this question to.
Brian
