[lldb-dev] Current quality/support of lldb on 32-bit Linux systems

[Matthew Gardiner]

Hi Todd,

I fixed one of the 32-bit linux problems I've been encountering. The 
problem (I think) is that the POSIXThread::GetRegisterContext() in 
POSIXThread.cpp was creating RegisterContextLinux_x86_64 regardless of 
the target_arch.GetCore().

I currently have no commit access so I'm publishing my diff, in case 
someone else in the mailing list (CCd) perhaps has the time to pursue 
this further.
