winapi - What is the maximum size of an integer (x86)? -
i'm going upgrade vc++ 2008 vc++ 2010 or 2012. before upgrading have questions:
my compiler supports largest
__int64
integers.__int128
supported in version vc++ 2010, 2012 , on?my current compiler doesn't support
_win64
or_win32
check windows platform. doubt_integral_max_bits
solution;64
if it's run in win32, or128
otherwise. true?
for of compilers mention, 64 bit integer types exist both 32 , 64 bit targets. however, there no 128 bit integer types. so, _integral_max_bits
evaluates 64 of listed compilers, , both 32 , 64 bit targets.
the best can use sse2 intrinsic __m128i
depends on presence of sse2 unit on processor. don't need upgrade able use that. it's available in vs2008 also.
