Description John Reiser 2008-04-29 15:59:52 UTC

Description of problem: There is no way to inspect which symbols appear in the
DT_HASH or DT_GNU_HASH tables.  This makes it more difficult that necessary to
document or debug problems involving runtime dynamic symbol lookup.


Version-Release number of selected component (if applicable):
binutils-2.18.50.0.6-2.i386


How reproducible: always


Steps to Reproduce:
1. readelf --all /bin/date
2.
3.
  
Actual results: no designation of which symbols appear in DT_HASH or DT_GNU_HASH


Expected results: some designation of which symbols appear in DT_HASH or
DT_GNU_HASH tables.

Apparenly you haven't tried readelf -Ds

Comment 2 John Reiser 2008-04-30 00:05:36 UTC

The usage documentation claims that "readelf -Ds" uses the dynamic section info
when displaying symbols, but the output says "Symbol table of '.gnu.hash'". 
Those could be two different collections of symbols, particularly if there are bugs.
