pub(crate) fn global_llvm_features(sess: &Session, for_cfg: bool) -> Vec<String>Expand description
The list of LLVM features computed from CLI flags (-Ctarget-cpu, -Ctarget-feature,
--target and similar).
If for_cfg is true then we are assembling the feature list for the purpose of populating
[rustc_codegen_ssa::TargetConfig] based on what LLVM actually enables in this configuration.
-Ctarget-feature should be ignored in that case since it is already processed separately.
