Howard Hinnant 5c67986156 A good start on ecma regex's. Maybe even feature complete, not sure yet. Also an unrelated fix to is_constructible thanks to Daniel Krugler.

Howard Hinnant 8c459a14a9 Marked subexpressions in a loop in basic posix working (only lightly tested so far) 
llvm-svn: 107889
 2010-07-08 17:43:58 +00:00
Howard Hinnant 189b212662 First loop test passed. The data structure and search algorithm is still crude and in-flux. But this milestone needed to be locked in. Right now every loop is implemented in terms of a structure that will handle the most complicated {min, max} loop. Though only *-loops are tested at the moment. In a future iteration *-loops will likely be optimized a little more. The only tests are for basic posix so far, but I have prototype code running for extended posix and ecma. The prototype code lacks the complicating properties of the real <regex> requirements though.
