http://git.dreamy.place/mirrors/rust/atom?h=1.60.02022-03-14T15:49:31+00:00bootstrap: correct reading of flags for llvm2022-03-14T15:49:31+00:00Jon Gjengsetjongje@amazon.com2022-03-01T00:40:08+00:00urn:sha1:9823bc6952176e04d764e099d7a881483084313c
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:

Note that this also necessitated an update to compiletest to treat
CXXFLAGS separately from CFLAGS.
Statically compile libstdc++ everywhere if asked2022-03-14T15:47:57+00:00Jon Gjengsetjongje@amazon.com2022-03-08T00:59:10+00:00urn:sha1:099acb0c44d5a087fd1580fba699e51bfeacf3f8
PR #93918 made it so that `-static-libstdc++` was only set in one place,
and was only set during linking, but accidentally also made it so that
it is no longer passed when building LLD or sanitizers, only when
building LLVM itself. This moves the logic for setting
`-static-libstdc++` in the linker flags back to `configure_cmake` so
that it takes effect for all CMake invocations in `native.rs`.
As a side-effect, this also causes libstdc++ to be statically compiled
into sanitizers and LLD if `llvm-tools-enabled` is set but
`llvm-static-stdcpp` is not, even though previously it was only linked
statically if `llvm-static-stdcpp` was set explicitly. But that seems
more like the expected behavior anyway.
bootstrap: -static-libstdc++ is a linker flag2022-02-12T00:09:57+00:00Jon Gjengsetjongje@amazon.com2022-02-11T20:03:51+00:00urn:sha1:36692741a2edef04a92021dcde05d9fa124f25e6
Fixes #70468. Closes #89983.
bootstrap: make LLVM build respect *FLAGS envvars2022-02-12T00:09:38+00:00Jon Gjengsetjongje@amazon.com2022-02-11T19:44:44+00:00urn:sha1:07dae5a97b64100f5abd511f1e2d5a6263a54006
This tidies up the logic in `src/bootstrap/native.rs` such that:
- `CMAKE_*_LINKER_FLAGS` is not overridden if we add to it twice.
- `CMAKE_*_FLAGS` also include the standard `*FLAGS` environment
variables, which CMake respects when we _don't_ set `CMAKE_*_FLAGS`.
- `llvm.ldflags` from `config.toml` appends to the ldflags Rust's
bootstrap logic adds, rather than replacing them.
Fixes #93880.

I'm working on some LLVM patches in concert with a Rust patch, and it's
helping me quite a bit to have this as an option. It doesn't seem that
hard, so I figured I'd formalize it in x.py and send it upstream.
