Re: [lldb-dev] environment vars not passed through to linux targets

[Christopher Book via lldb-dev]

Yes, exactly.  So things like LD_LIBRARY_PATH, PATH and others that are set
based on the target linux env.  The client doesn't have this information
available to manually set them all.

Re: [lldb-dev] environment vars not passed through to linux targets

[Stephane Sezer via lldb-dev]

Which set of env vars did you want the child process to inherit? The env
vars of the platform process on the remote?

[lldb-dev] Port LLDB to ppc64le (ABIv2) on linux

[Gustavo Serra Scalet via lldb-dev]

Hi,

I'm interested in porting LLDB to PowerPC 64 little endian (e.g: POWER8 
machines) on Linux platform but before starting such work, I wanted to know if 
somebody is already doing it or also if there is anything prohibitive in doing 
so (Probably relevant to this question: clang supports POWER8 already, which is 
good).

The interesting resources I found at the moment are: the special debug 
registers as described on the ISA [1]; dealing with Ptrace API[2]; and also a 
presentation pointing out how LLDB was ported to MSP430 architecture[3].

Are there any other resources you'd recommend? I tried searching in the mailing 
list but I didn't find more relevant information.

Thanks. Comments are welcome :-)
