Respect ranlib specified for target during LLVM build

2022-04-15T14:51:09+00:00

The ranlib specified for the target was never actually transferred into the builder configuration. In the dist-x86_64-linux build we ended up using ranlib instead of llvm-ranlib.

Remove build_helper

2022-03-05T14:31:22+00:00

The majority of the code is only used by either rustbuild or rustc_llvm's build script. Rust_build is compiled once for rustbuild and once for every stage. This means that the majority of the code in this crate is needlessly compiled multiple times. By moving only the code actually used by the respective crates to rustbuild and rustc_llvm's build script, this needless duplicate compilation is avoided.

bootstrap: correct reading of flags for llvm

First, this reverts the `CFLAGS`/`CXXFLAGS` of #93918. Those flags are already read by `cc` and populated into `Build` earlier on in the process. We shouldn't be overriding that based on `CFLAGS`, since `cc` also respects overrides like `CFLAGS_{TARGET}` and `HOST_CFLAGS`, which we want to take into account. Second, this adds the same capability to specify target-specific versions of `LDFLAGS` as we have through `cc` for the `C*` flags: https://github.com/alexcrichton/cc-rs#external-configuration-via-environment-variables Note that this also necessitated an update to compiletest to treat CXXFLAGS separately from CFLAGS.

bootstrap: fall back to auto-detected CXX

This allows us to use the C++ compiler configured via `CXX_target_triple` env vars

Teach bootstrap about target files vs target triples

2020-07-17T14:08:04+00:00

`rustc` allows passing in predefined target triples as well as JSON target specification files. This change allows bootstrap to have the first inkling about those differences. This allows building a cross-compiler for an out-of-tree architecture (even though that compiler won't work for other reasons). Even if no one ever uses this functionality, I think the newtype around the `Interned` improves the readability of the code.
