This change introduces the --skip-stage0-validation flag, which permits the use of any desired version of the stage0 compiler without verifying its version. Signed-off-by: onur-ozkan <work@onurozkan.dev>
Either generate it with the actual codegen backend dylib or omit it entirely when the cranelift backend is disabled for this build.
Simplify #[cfg] blocks fmt don't try to use the more appropriate direntry on musl
Don't use LFS64 symbols on musl Supersedes rust-lang#106246 ~~Note to packagers: If your distro's musl package has already been updated, then you won't be able to build a newer version of rust until a new rust release is made with these changes merged (which can be used to bootstrap). I'm using a super hacky method to bypass this by creating a stub library with LFS64 symbols and building a patched rust, so the symbols satisfy the build requirements while the final compiler build has no references to LFS64 symbols, example: https://codeberg.org/kiss-community/repo/pulls/160/files~~ Doesn't seem to be necessary with new rustup nightly builds, likely due to updates to vendored crates cc `@alyssais`
… r=Mark-Simulacrum add bootstrap flag `--skip-stage0-validation` This change introduces the `--skip-stage0-validation` flag, which permits the use of any desired version of the stage0 compiler without verifying its version. Additionally, stage0 compiler validation check is reverted(rust-lang#115103) to its default enabled state. Helps to rust-lang#115065 r? Mark-Simulacrum
…_target_feature_sgx, r=Mark-Simulacrum Fix closure-inherit-target-feature test for SGX platform PR rust-lang#116078 adds the `closure-inherit-target-feature.rs` test that checks the generated assembly code for closures. These checks explicitly check the presence of `ret` instructions. This is incompatible with the SGX target as it explicitly rewrites all `ret` instructions to mitigate LVI vulnerabilities of certain processors. This PR simply ignores these tests for the SGX platform. cc: `@jethrogb`
…k-Simulacrum memcpy assumptions: link to source showing that GCC makes the same assumption I finally stumbled upon a source showing that GCC also generates overlapping `memcpy`. So if we're linking major C compilers making such assumptions here, let's have both clang and GCC.
…acrum pass `CODEGEN_BACKENDS` to docker The backends to build are now defined in the `CODEGEN_BACKENDS` env var. It's correctly set in CI, but wasn't passed to docker, hence cg_clif wasn't actually built in rust-lang#81746. r? `@Kobzol:` I locally tried `CODEGEN_BACKENDS="cranelift" DEPLOY=1 src/ci/docker/run.sh dist-x86_64-linux` and this change was enough for `ci/run.sh` to read the env var. So I'll try as-is and we'll see.
