FEAT: dwfl_module_addrname() should also return lowpc+highpc
Last modified: 2007-11-30 17:11:58 EST
Description of problem:
If DIE is not available but dwfl_module_addrname() is still able to locate the
symbol it returns only its name. It could definitely return its base address
(lowpc) and according to ST_SIZE != 0 it could also return its highpc.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. name = dwfl_module_addrname (mod, 0xdeadf00d);
GElf_Addr lowpc, highpc;
name = dwfl_module_addrname (mod, 0xdeadf00d, &lowpc, &highpc);
if (name != NULL)
if (name != NULL && highpc != 0)
Patching dwfl_module_addrname() is trivia but some elfutils-wise API proposal
would be nice.
I can add a similar call that takes an address but returns full info in the same
way as dwfl_module_getsym.
Confirming I would like such API for these needs. I hope it would
reuse/refactor some of the existing code of
Of course it was already using that internally. I've added the new
dwfl_module_addrsym call upstream, it was trivial.
Is the patch available?
0.127 includes dwfl_module_addrsym
