Preparing for elfutils 0.169

2017-05-01 Thread Mark Wielaard
Hi hackers,

It is May already and 0.168 was released 4 months ago. So it is really
time to get a new release out (we normally do one every 3 months). There
have been a couple of crasher fixes that would be good to make sure are
in a stable (distro) release. So I would like to do a 0.169 release this
week.

The frame pointer unwinder patches for x86_64, i686 and aarch64 seem
good to go in before release. And I'll do another scan over the
submitted patches on the mailinglist from the last 2 weeks.

I most likely won't apply the big gnulib modules integration patch
before the release. I am afraid that will be a little too disruptive
right for a release. But I do think that is a good thing to integrate.
So if we integrate that soon after the release then we can test it a
little better for 0.170. I also didn't have time to finish my DWARF5
work. So that too would also go into the next release. We could do the
next release a bit quicker to compensate for 0.169 being a month late
and do 0.170 after 2 months (end of June/start of July).

Cheers,

Mark

Dumping the whole decoded line table with eu-readelf --debug-dump=decodedline
shows:

 
/home/marat/production/ue4/Engine/Source/Runtime/Core/Private/Linux/LinuxPlatformCrashContext.cpp

76:6   S0   0  0 +0x002c09be
<_Z20PlatformCrashHandleriP9siginfo_tPv+0x10e>

So there we are able to also deduce that address 0x2c09b2 is associated with
LinuxPlatformCrashContext.cpp:595:3
