## Toolchain Compatibility
+<!-- NOTE: to update the below table, you can use this shell script:
+
+```sh
+rustup toolchain install --profile minimal nightly
+MINOR_VERSION=$(rustc +nightly --version | cut -d . -f 2)
+LOWER_BOUND=44
+
+llvm_version() {
+ toolchain="$1"
+ printf "Rust $toolchain | Clang "
+ rustc +"$toolchain" -Vv | grep LLVM | cut -d ':' -f 2 | tr -d ' '
+}
+
+for version in `seq $LOWER_BOUND $((MINOR_VERSION - 2))`; do
+ toolchain=1.$version.0
+ rustup toolchain install --no-self-update --profile minimal $toolchain >/dev/null 2>&1
+ llvm_version $toolchain
+done
+```
+
+-->
+
In order for this kind of LTO to work, the LLVM linker plugin must be able to
handle the LLVM bitcode produced by both `rustc` and `clang`.
