# TSAN requires XPC on Darwin, which we have no public/free source files for. We can depend on the Apple frameworks
|
|
# to get it, but they're unfree. Since LLVM is rather central to the stdenv, we patch out TSAN support so that Hydra
|
|
# can build this. If we didn't do it, basically the entire nixpkgs on Darwin would have an unfree dependency and we'd
|
|
# get no binary cache for the entire platform. If you really find yourself wanting the TSAN, make this controllable by
|
|
# a flag and turn the flag off during the stdenv build. I realize that this LLVM isn't used in the stdenv but I want to
|
|
# keep it consistent with 4.0. We really shouldn't be copying and pasting all this code around...
