# Specify the desired LLVM version in an overlay to avoid the use of

# mismatching versions.

#

# The llvmPackages that we take things (clang, libc++ and such) from

# is specified explicitly to be llvmPackages_11 to keep the

# bootstrap-tools stable.  However, tools like otool,

# install_name_tool and strip are taken straight from stdenv.cc,

# which, after the bump, is a different LLVM version altogether.

#

# The original intent was that bootstrap-tools specified LLVM 11

# exhaustively but it didn't. That should be rectified with this

# PR. As to why stick with 11? That's just to keep the

# bootstrap-tools unchanged.
