[PATCH] D117117: [FileCheck] Allow literal '['s before "[[var...]]"

[Thomas Preud'homme via Phabricator via llvm-commits]

thopre added a comment.

Could you add a new testcase somewhere in `llvm/test/FileCheck`? Thanks!



================
Comment at: llvm/lib/FileCheck/FileCheck.cpp:1194
+    size_t FixedMatchEnd =
+        std::min(PatternStr.find("{{", 1), PatternStr.find("[[", 1));
     RegExStr += Regex::escape(PatternStr.substr(0, FixedMatchEnd));
----------------
Why the special treatment for `{{` here since only the `[[[` case is handled above?
