TTMath 0.8.4

Enhancements:

• Fixed: UInt:DivInt() didn't check whether the divisor is zero
• There was a hardware interruption when the divisor was zero(now the method returns one)
• Fixed: the problem with GCC optimization on x86_64
• Sometimes when using -O2 or -O3 GCC doesn't set correctly
• The stack pointer (actually the stack is used for other things)
• And you cant use instructions like push/pop in assembler code.
• All the asm code in x86_64 have been rewritten, now instructions push/pop are not used, other thing which have access to stack (like "m" (mask) constraints in Rcl2 and Rcr2) have also gone away,
• Now the library works well with -O2 and -O3 and the asm code
• Is a little faster
• Added: UInt:PrintLog(const char * msg, std:ostream & output) used (for debugging purposes) by macro TTMATH_LOG(msg)
• (it is used in nearly all methods in UInt class)
• Added: macro TTMATH_DEBUG_LOG: when defined then TTMATH_LOG() put some debug information (to std:cout)
• Added: ttmathuint_x86.h, ttmathuint_x86_64.h, ttmathuint_noasm.h,
• All the methods which are using assembler code have been rewritten to no-asm forms
