Module compile

Implementation of compiling various phases of the compiler and standard library.

This module contains some of the real meat in the bootstrap build system which is where Cargo is used to compile the standard library, libtest, and the compiler. This module is also responsible for assembling the sysroot as it goes along from the output of the previous stage.

Structs

Assemble

Prepare a compiler sysroot.

BuiltRustc

Represents information about a built rustc.

CargoTarget

CraneliftCodegenBackend

GccCodegenBackend

GccCodegenBackendOutput

Output of the compile::GccCodegenBackend step. It includes the path to the libgccjit library on which this backend depends.

Rustc

Build rustc using the passed build_compiler.

RustcLink 🔒

RustcLink copies compiler rlibs from a rustc build into a compiler sysroot. It works with (potentially up to) three compilers:

StartupObjects

Std

Build a standard library for the given target using the given build_compiler.

StdLink

Link all libstd rlibs/dylibs into a sysroot of target_compiler.

Sysroot

Enums

CargoMessage

Functions

add_to_sysroot

Link some files into a rustc sysroot.

apple_darwin_sign_file 🔒

apple_darwin_update_library_name 🔒

compiler_file

compiler_rt_for_profiler 🔒

Tries to find LLVM’s compiler-rt source directory, for building library/profiler_builtins.

copy_and_stamp 🔒

copy_codegen_backends_to_sysroot 🔒

Creates the codegen-backends folder for a compiler that’s about to be assembled as a complete compiler.

copy_llvm_libunwind 🔒

copy_sanitizers 🔒

Copies sanitizer runtime libraries into target libdir.

copy_self_contained_objects 🔒

Copies third party objects needed by various targets for self-contained linkage.

copy_third_party_objects 🔒

Copies third party objects needed by various targets.

cp_rustc_component_to_ci_sysroot 🔒

get_codegen_backend_file

Gets the path to a dynamic codegen backend library from its build stamp.

is_lto_stage

We only use LTO for stage 2+, to speed up build time of intermediate stages.

normalize_codegen_backend_name

Normalize the name of a dynamic codegen backend library.

run_cargo

rustc_cargo

rustc_cargo_env

rustc_llvm_env 🔒

Pass down configuration from the LLVM build into the build of rustc_llvm and rustc_codegen_llvm.

std_cargo

Configure cargo to compile the standard library, adding appropriate env vars and such.

std_crates_for_run_make

Resolves standard library crates for Std::run_make for any build kind (like check, doc, build, clippy, etc.).

stream_cargo

strip_debug

write_codegen_backend_stamp 🔒

Write filtered files into the passed build stamp and returns it.
