# Unless you're developing for a target where Rust CI doesn't build a compiler
# toolchain or changing LLVM locally, you probably want to set this to true.
#
# It's currently false by default due to being newly added; please file bugs if
# enabling this did not work for you on x86_64-unknown-linux-gnu.
# Other target triples are currently not supported; see #77084.
# This is false by default so that distributions don't unexpectedly download
# LLVM from the internet.
#
# All tier 1 targets are currently supported; set this to `"if-supported"` if
# you are not sure whether you're on a tier 1 target.
#
# We also currently only support this when building LLVM for the build triple.
