This is the first step to enable download of precompiled GCC
Co-authored-by: whiteio <chriswhiteiodev@gmail.com>
The size of this struct depends on the alignment of `u128`, for example powerpc64le and s390x have align-8 and end up with only 280 bytes. Our 64-bit tier-1 arches are the same though, so let's just assert on those.
We want kernels to be able to use this bare metal target, so let's enable the sanitizers that kernels want to use.
Enable `unreachable_pub` lint in `test` and `proc_macro` crates This PR enables the [`unreachable_pub`](https://doc.rust-lang.org/rustc/lints/listing/allowed-by-default.html#unreachable-pub) lint as warn in the `test` and `proc_macro` crates. The diff was mostly generated with `./x.py fix --stage 1 library/proc_macro/ -- --broken-code`, as well as manual edits for code in macros and in tests. Continuation of rust-lang#134286 r? libs
Make it possible to build GCC on CI This is the first step towards eventually enabling download of precompiled GCC from our CI. Currently, we prebuild `libgccjit` on CI and cache it in Docker. This PR improves the bootstrap GCC step to make it work on CI, and also to make it faster by using sccache. After this change, an actual build on CI should take only 2-3 minutes. Note that this PR does not yet remove the `build-gccjit.sh` script and replace it with the bootstrap step, I'll leave that to a follow-up PR. The added `flex` package and the ZSTD library fix were needed to make GCC build on CI. CC ``````@GuillaumeGomez`````` r? ``````@onur-ozkan``````
support wasm inline assembly in `naked_asm!` fixes rust-lang#135518 Webassembly was overlooked previously, but now `naked_asm!` and `#[naked]` functions work on the webassembly targets. Or, they almost do right now. I guess this is no surprise, but the `wasm32-unknown-unknown` target causes me some trouble. I'll add some inline comments with more details. r? ```````@bjorn3``````` cc ```````@daxpedda,``````` ```````@tgross35```````
