Module llvm 

Compilation of native dependencies like LLVM.

Native projects like LLVM unfortunately aren’t suited just yet for compilation in build scripts that Cargo has. This is because the compilation takes a very long time but also because we don’t want to compile LLVM 3 times as part of a normal bootstrap (we want it cached).

LLVM and compiler-rt are essentially just wired up to everything else to ensure that they’re always in place if needed.

Structs

BuiltEnzyme

BuiltOmpOffload

BuiltRustOffload

CcFlags 🔒

Allows each step to add C/Cxx flags which are only used for a specific cmake invocation.

CrtBeginEnd

DownloadedLlvm

Enzyme

FileCheck

Returns the path to FileCheck LLVM binary for the specified target.

LdFlags 🔒

Linker flags to pass to LLVM’s CMake invocation.

Libunwind

Lld

Llvm

LlvmBuildInfo

LlvmFromCi

This step explicitly represents the output of downloaded LLVM. The step will provide an output only if all the following is true:

LlvmOutput

Result of building or downloading LLVM artifacts.

OmpOffload

RustOffload

SanitizerRuntime

Sanitizers

Enums

LlvmBuildStatus

LlvmKind

Constants

LLVM_CI_LINK_TYPE_PATH

Path where a file containing the link type (dynamic or static) is stored in the LLVM CI tarball.

LLVM_INVALIDATION_PATHS

Paths whose changes invalidate LLVM downloads.

Functions

check_llvm_version 🔒

configure_cmake 🔒

configure_llvm 🔒

detect_llvm_freshness 🔒

Detect whether LLVM sources have been modified locally or not.

get_llvm_build_status

This returns whether we’ve already previously built LLVM.

get_llvm_profile 🔒

get_llvm_version

get_llvm_version_major

get_var 🔒

is_ci_llvm_available_for_target 🔒

Returns whether the CI-found LLVM is currently usable.

llvm_link_shared 🔒

Determine whether llvm should be linked dynamically. NOTE: This only contains the value from the config. If you need to figure out the correct value for a specific LLVM instance, use prebuilt_llvm_config instead.

prebuilt_llvm_output

Attempt to return prebuilt LLVM output information, either downloaded from CI or through an externally provided LLVM.

supported_sanitizers 🔒

Returns sanitizers available on a given target.

try_download_ci_llvm 🔒
