From: mxlol233 <[email protected]>
This commit implemented a feature gate to check `intrinsics`.
gcc/rust/ChangeLog:
* checks/errors/rust-feature-gate.cc: Add implementation for
`void FeatureGate::visit (AST::ExternBlock &block)`. Add `valid_feature`
construction process in `FeatureGate::check`.
* checks/errors/rust-feature-gate.h: Add declaration for
`void FeatureGate::visit (AST::ExternBlock &block)`. Add private
variable `valid_feature`.
* checks/errors/rust-feature.h: Change `issue` to `m_issue`.
gcc/testsuite/ChangeLog:
* rust/compile/const-issue1440.rs: Add crate feature: `intrinsics`.
* rust/compile/feature_intrinsics.rs: New file.
* rust/compile/issue-1031.rs: Add crate feature: `intrinsics`.
