[LLVMdev] Recovering variable names from bitcode

I have been facing a few problems getting names of variables from the
bitcode. The bitcode does contain debug metadata. The first problem is
regarding `memtmp' variables (apparently, the original variable name is no
longer present in the bitcode). The other two problems concern OpenMP. In
one case, the instruction is not named and hence establishing a connection
to the debug metadata does not seem possible. In the other case, I am
noticing some extra fields present in the `omp_data_s' structure (these
fields are not present in the source code) and hence the `alloca' does not
match the metadata definition.

Here are the details:

Does lldb have similar goals? If yes, which files should I be looking at?

Any pointers are appreciated!
