proc_macro: Tweak doc comments and negative literals This commit tweaks the tokenization of a doc comment to use `#[doc = "..."]` like `macro_rules!` does (instead of treating it as a `Literal` token). Additionally it fixes treatment of negative literals in the compiler, for exapmle `Literal::i32(-1)`. The current fix is a bit of a hack around the current compiler implementation, providing a fix at the proc-macro layer rather than the libsyntax layer. 2018-03-30 09:55:54 +00:00
