Francis Visoiu Mistrih b213b27ee3 [YAML] Add support for non-printable characters ... LLVM IR function names which disable mangling start with '\01' (https://www.llvm.org/docs/LangRef.html#identifiers). When an identifier like "\01@abc@" gets dumped to MIR, it is quoted, but only with single quotes. http://www.yaml.org/spec/1.2/spec.html#id2770814: "The allowed character range explicitly excludes the C0 control block allowed), the surrogate block #xD800-#xDFFF, #xFFFE, and #xFFFF." http://www.yaml.org/spec/1.2/spec.html#id2776092: "All non-printable characters must be escaped. [...] Note that escape sequences are only interpreted in double-quoted scalars." This patch adds support for printing escaped non-printable characters between double quotes if needed. Should also fix PR31743. Differential Revision: https://reviews.llvm.org/D41290 llvm-svn: 320996		2017-12-18 17:38:03 +00:00
