Re: Re. Reduction of logic to arithmetic

2013-04-21 Thread Ranganath kulkarni
Dear Sir By using this formula we can reduce the decision algorithm or logical test to single mathematical equation or algebraic manipulation. This converts logical operation to arithmetic operation. In otherwords it is a simple algorithm without decision trees. Therefore we can make elegant prog

Completing libstdc++ regex in GSoC

2013-04-21 Thread Tim Shen
Hi there, I'm a student interested in GCC and want to make a proposal of completing regex in libstdc++. I've read include/bits/regex.h. As far as I can see, the implementation of regex_traits is partial because C++11(N3290) requires two specializations : regex_traits and regex_triats (28.3.5), whi

Macro for C++14 support

I'm starting to implement some new library features voted into C++14 at the Bristol meeting and am wondering what feature check to use. Will there be a macro like _GXX_EXPERIMENTAL_CXX1Y__ to correspond to -std=c++1y? Alternatively we could set the value of __cplusplus to 201400L but I'm not sure
