Dmitri Hrybenko	3f2006a00b	stdlib/UnicodeTrie: add more comments, replace a _precondition()/#if ... pair with _sanityCheck Swift SVN r19395	2014-07-01 13:18:20 +00:00
Dave Abrahams	8e7d45f2c0	[stdlib] Normalize .gyb files ... - Follow LLVM conventions for emacs mode specification - Use local variables suffix to make the output read-only (at least on Emacs) - But drop the admonitions not to edit the generated files; line-directive mostly takes care of that problem now.

Dmitri Hrybenko	4814e00fda	stdlib/String: implement Unicode extended grapheme cluster segmentation ... algorithm The implementation uses a specialized trie that has not been tuned to the table data. I tried guessing parameter values that should work well, but did not do any performance measurements. There is no efficient way to initialize arrays with static data in Swift. The required tables are being generated as C++ code in the runtime library. rdar://16013860 Swift SVN r19340	2014-06-30 14:38:53 +00:00
