Statics

INIT 🔒

Functions

configure_llvm 🔒 ^⚠

get_host_cpu_name 🔒

Returns the host CPU name, according to LLVM.

get_version 🔒

Returns the version of LLVM that we are actually linked to at runtime.

global_llvm_features 🔒

The list of LLVM features computed from CLI flags (-Ctarget-cpu, -Ctarget-feature, --target and similar).

handle_native 🔒

If the given string is "native", returns the host CPU name according to LLVM. Otherwise, the string is returned as-is.

init 🔒

llvm_features_by_flags 🔒

The target features for compiler flags other than -Ctarget-features.

llvm_target 🔒

The LLVM target triple to use for the session’s target.

llvm_target_features 🔒

print 🔒

print_passes 🔒

print_target_cpus 🔒

print_target_features 🔒

print_version 🔒

require_inited 🔒

target_config 🔒

Used to generate cfg variables and apply features. Must express features in the way Rust understands them.

target_cpu 🔒

target_has_mnemonic 🔒

time_trace_profiler_finish 🔒

to_llvm_features 🔒

Convert a Rust feature name to an LLVM feature name. Returning None means the feature should be skipped, usually because it is not supported by the current LLVM version.

tune_cpu 🔒

update_target_reliable_float_cfg 🔒

Determine whether or not experimental float types are reliable based on known bugs.
