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

README

This directory contains tests for the MIR file format parser and printer. It
was necessary to split the tests across different targets as no single target
covers all features available in machine IR.

Tests for codegen passes should NOT be here but in test/CodeGen/sometarget. As
a rule of thumb this directory should only contain tests using
'llc -run-pass none'.
