Yucheng Low d8af53e222 restored missing header 2015-12-31 15:48:01 -08:00
Yucheng Low a0dfd81516 Lockfree mem_block_cache only active if std::atomic is available 2015-12-31 15:46:20 -08:00
Yucheng Low 3f14031142 Updated with platform checks 2015-12-15 14:26:03 -08:00
Yucheng Low b9f55efe98 Made the mem_cache_block lockfree 
This *significantly* improves parallel performance of regex.
Currently if I have a large number of threads all using regexes; even if
they are using idependent regex objects, performance is still extremely poor
due to the lock inside of the mem_block_cache.

Mikael Olenfalk 6d2be646d8 universal-windows: Do not build w32_regex_traits 
Since Vista LCID has been deprecated and locales are now using string-names,
this makes the effort to support w32_regex_traits quite large, therefore we
opt to disable w32_regex_traits right now when targeting universal-windows.
