This is misleading. "New file" is idiomatic for "this is a new file". You probably meant "I've added new file rules in the makefile". Can you rephrase that and make it less confusing? Thanks! |
This change moves the unused variable checker from the type resolver to HIR. We can now use the HIR Default Visitor, and it will be much more easier to implement other unused lints with this change. gcc/rust/ChangeLog: * Make-lang.in: Add new files rules in Makefile. * lang.opt: Add new flag. * rust-session-manager.cc (Session::compile_crate): Execute new variable checker. * checks/lints/unused-var/rust-unused-var-checker.cc (UnusedVarChecker): Implement unused variable checker. * checks/lints/unused-var/rust-unused-var-checker.h (UnusedVarChecker): Implement unused variable checker. * checks/lints/unused-var/rust-unused-var-collector.cc (UnusedVarCollector): Implement unused variable collector. * checks/lints/unused-var/rust-unused-var-collector.h (UnusedVarCollector): Implement unused variable collector. * checks/lints/unused-var/rust-unused-var-context.cc (UnusedVarContext): Implement unused variable context. * checks/lints/unused-var/rust-unused-var-context.h (UnusedVarContext): Implement unused variable context. gcc/testsuite/ChangeLog: * rust/compile/static_item_0.rs: New test. * rust/compile/template_function_0.rs: New test.
