[Patch] parisc support.
- From: Kurt Roeckx <kurt at roeckx dot be>
- To: elfutils-devel at lists dot fedorahosted dot org
- Date: Tue, 20 Jul 2010 16:26:59 +0200
- Subject: [Patch] parisc support.
Hi,
This is an updated patch for the parisc support I send last year.
The only change since then is that retval.c now uses
dwarf_aggregate_size().
