shafik added inline comments.
================
Comment at: clang/test/Analysis/cfg.cpp:227
+enum MyEnum : int { A, B, C };
static const enum MyEnum D = (enum MyEnum) 32;
----------------
This is undefined behavior unless the enum has a fixed type, using `: int`
above does that.
================
Comment at: clang/test/SemaCXX/enum-scoped.cpp:330
namespace PR35586 {
- enum C { R, G, B };
+ enum C { R=-1, G, B };
enum B { F = (enum C) -1, T}; // this should compile cleanly, it used to
assert.
----------------
@erichkeane not sure if this fix for the test maintains the original intent of
the test or not.
================
Comment at:
cross-project-tests/debuginfo-tests/clang_llvm_roundtrip/simplified_template_names.cpp:28
void ttp_user() { }
-enum Enumeration { Enumerator1, Enumerator2, Enumerator3 = 1 };
+enum Enumeration : int { Enumerator1, Enumerator2, Enumerator3 = 1 };
enum class EnumerationClass { Enumerator1, Enumerator2, Enumerator3 = 1 };
----------------
These enums are used with undefined behavior later on by casting values outside
of the range and using them as template arguments. Given them a fixed underling
type removes the UB.
