I was not aware of `diagtool tree`, but it produces very useful output (it's colored in the terminal):
```
GREEN = enabled by default
YELLOW = disabled by default
RED = unimplemented (accepted for GCC compatibility)
-W
-Wextra
-Wdeprecated-copy
-Wdeprecated-copy-with-user-provided-copy
-Wmissing-field-initializers
-Wmissing-designated-field-initializers
-Wignored-qualifiers
-Wignored-reference-qualifiers
-Winitializer-overrides
-Wsemicolon-before-method-body
-Wmissing-method-return-type
-Wsign-compare
-Wunused-parameter
-Wunused-but-set-parameter
-Wnull-pointer-arithmetic
-Wgnu-null-pointer-arithmetic
-Wnull-pointer-subtraction
-Wempty-init-stmt
-Wstring-concatenation
-Wfuse-ld-path
-Wcast-function-type-mismatch
```
This is pretty handy, and I think it would make a great addition to the [diagnostic reference documentation](https://clang.llvm.org/docs/DiagnosticsReference.html), which is highly searchable and discoverable. Thanks @nickdesaulniers for mentioning `diagtool`, I was not aware of it, but it's apparently been around since 2011.
