Fwd: compiler-rt

Oleg Smolsky via cfe-dev
(Sort of) repost.
Things would be significantly easier if the llvm libunwind would be renamed avoiding the name clash with the "standard" libunwind.
I think someone proposed this recently (or complained about this renaming not being done).

Dear libcxx community,

I would like to compile the latest libcxx on Ubuntu 16.04.
Regarding the use of compiler-rt instead of libgcc and given there seems to be a dependency on libunwind i have the following questions:
  • Should i use the system libunwind or the llvm one?
  • Can i use libunwind.a instead of libunwind.so?
  • Should i set -D_GNU_SOURCE for the compile (there is at least one cmake test which fails without this if the system libunwind is used)?
  • There once was an activity (or at least a proposal) to combine compiler-rt with libunwind, is this still on target?

Thanks in advance for answers
