In https://github.com/rust-lang/compiler-builtins/pull/593, some builtins for f16/f128 were added. These don't work for all compiler backends, so add a `compiler-builtins-no-f16-f128` feature and disable it for cranelift and gcc. Also disable it for LLVM targets that don't support it. --- Cargo.lock | 4 ++-- .../build_system/build_sysroot.rs | 2 +- compiler/rustc_codegen_gcc/build_system/src/build.rs | 9 ++++++++- library/alloc/Cargo.toml | 7 +++++-- library/std/Cargo.toml | 4 ++-- library/sysroot/Cargo.toml | 2 +- 6 files changed, 19 insertions(+), 9 deletions(-) diff --git a/Cargo.lock b/Cargo.lock index 5e8d179e536..390d7c05f65 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -769,9 +769,9 @@ checksum = "55b672471b4e9f9e95499ea597ff64941a309b2cdbffcc46f2cc5e2d971fd335" [[package]] name = "compiler_builtins" -version = "0.1.109" +version = "0.1.114" source = "registry+https://github.com/rust-lang/crates.io-index" -checksum = "f11973008a8cf741fe6d22f339eba21fd0ca81e2760a769ba8243ed6c21edd7e" +checksum = "eb58b199190fcfe0846f55a3b545cd6b07a34bdd5930a476ff856f3ebcc5558a" dependencies = [ "cc", "rustc-std-workspace-core", diff --git a/compiler/rustc_codegen_cranelift/build_system/build_sysroot.rs b/compiler/rustc_codegen_cranelift/build_system/build_sysroot.rs index 196ff8fda75..557e90abdb3 100644 --- a/compiler/rustc_codegen_cranelift/build_system/build_sysroot.rs +++ b/compiler/rustc_codegen_cranelift/build_system/build_sysroot.rs @@ -276,7 +276,7 @@ fn build_clif_sysroot_for_triple( if channel == "release" { build_cmd.arg("--release");
