Description Petr Machata 2012-10-12 19:50:07 EDT
Spec URL: http://pmachata.fedorapeople.org/dwlocstat.spec
SRPM URL: http://pmachata.fedorapeople.org/dwlocstat-0.1-0.1.20121012git4557c3e.fc16.src.rpm

Description: dwlocstat is a tool for examining Dwarf location info coverage.  It
goes through DIEs of given binary's debug info that represent
variables and function parameters.  For each such DIE, it computes
coverage of that DIE's range by location expressions.

$ rpmlint dwlocstat.spec ../RPMS/ppc64/dwlocstat-0.1-0.1.20121012git4557c3e.fc16.ppc64.rpm ../SRPMS/dwlocstat-0.1-0.1.20121012git4557c3e.fc16.src.rpm 
2 packages and 1 specfiles checked; 0 errors, 0 warnings.

I tested the build in Fedora 16 ppc64 mock and Fedora 18 i686 mock (in addition to x86_64 live system).  During the build, you will likely see several messages like this:
error: DIE 1f036: dwarf_getlocation_addr: invalid DWARF. (skipping)

That comes from %check, where I run the program on itself to do elementary smoke testing.  The error messages come from elfutils, which doesn't have support for reading several location expression operators.  A patch implementing this support was upstreamed this week.
Comment 1 Michael Scherer 2012-11-03 10:56:04 EDT

it seems there is code from elfutils bundled with it, and while I can see the reason, I think this should be agreed by the FPC, could you see with them ?

( and add the breakdown of the license ). 

Otherwise, everything is good.

Thanks for review.  I went through the files, and the only actual copy from elfutils is eu-config.h.  This was only used for likely() and unlikely() predicates, and I can live without those, so I dropped eu-config.h.

known-dwarf.h is generated, I think I could hook it into a build process eventually to mirror what's in system dwarf.h, but for now it is unused at all, and I just dropped it.

The .cc and .hh files comprising dwlocstat itself (and dwarfstrings.c/.h as well) grew up on elfutils "dwarf" branch.  But it's very unlikely that this branch will get merged anytime soon (or ever), which is why I split this small tool off to a separate project.  I don't think this counts as embedding a copy, this code never was part of upstream elfutils tarball.

I did that now.
