I still need to fix tests that does not pass testsuite (with new warning, it seems logic) |

Hello, |
Adds missing warnings for Enums. Fixes: Rust-GCC#4367 gcc/rust/ChangeLog: * checks/lints/rust-lint-scan-deadcode.h: Add warnings for Enums. Signed-off-by: lenny.chiadmi-delage <lenny.chiadmi-delage@epita.fr>
Adds simple test with unused Enum. Addresses Rust-GCC#4367 gcc/testsuite/ChangeLog: * rust/compile/issue-4367.rs: New test. Signed-off-by: lenny.chiadmi-delage <lenny.chiadmi-delage@epita.fr>
gcc/rust/ChangeLog: * checks/lints/rust-lint-scan-deadcode.h: Add more functions that are reused throught the visitor and make `should_warn` perform all checks.
Since we now check for unused enums, we have to tweak the testuite to reflect that. gcc/testsuite/ChangeLog: * rust/compile/derive-debug1.rs: Add missing `pub` qualifier. * rust/compile/derive-hash1.rs: Likewise. * rust/compile/derive_clone_enum1.rs: Likewise. * rust/compile/derive_clone_enum2.rs: Likewise. * rust/compile/derive_clone_enum3.rs: Likewise. * rust/compile/enum_discriminant1.rs: Likewise. * rust/compile/for-loop1.rs: Likewise. * rust/compile/for-loop2.rs: Likewise. * rust/compile/glob_import_enum.rs: Likewise. * rust/compile/if_let_expr_simple.rs: Likewise. * rust/compile/issue-3382.rs: Likewise. * rust/compile/issue-3550.rs: Likewise. * rust/compile/issue-3597.rs: Likewise. * rust/compile/issue-3605.rs: Likewise. * rust/compile/issue-3651.rs: Likewise. * rust/compile/issue-3670.rs: Likewise. * rust/compile/issue-4367.rs: Likewise. * rust/compile/issue-850.rs: Likewise. * rust/compile/iterators1.rs: Likewise. * rust/compile/parse_associated_type_as_generic_arg.rs: Likewise. * rust/compile/parse_associated_type_as_generic_arg2.rs: Likewise. * rust/compile/parse_associated_type_as_generic_arg3.rs: Likewise. * rust/compile/torture/tuple_enum_variants.rs: Likewise. * rust/compile/torture/utf8_identifiers.rs: Likewise. * rust/compile/try-trait.rs: Likewise. * rust/compile/try_block1.rs: Likewise. * rust/compile/while_let1.rs: Likewise. * rust/execute/torture/enum_intrinsics2.rs: Likewise. * rust/execute/torture/for-loop1.rs: Likewise. * rust/execute/torture/for-loop2.rs: Likewise. * rust/execute/torture/iter1.rs: Likewise.
