Okay... I\'m getting kind of desperate trying to get this code to work with strict aliasing turned on (and -O3).
In most tutorials or code snippets on the net one sees the following: float *arr= (float*) _aligned_malloc(length * sizeof(float), 16);
boost::optional<> works perfect for simple data types but as soon as used for a class inheriting from a class implementing an interface it fails when strict aliasing is enabled.
I\'m trying to facilitate automatic vectorization by the compiler in the blitz++ array library. For this reason, I\'d like to present a view of the array data that is in chunks of fixed-length vectors
I\'ve been reading about strict aliasing quite a lot lately. The C/C++ standards say that the following code is invalid (undefined behavior to be correct), since the compiler might have the value of a
I am trying to extract the bits from a float without invoking undefined behavior. Here is my first attempt:
I have the following code for having a small class for storage. #include <iostream> template<typename T>
One of the examples of undefined behavior from the C standard reads (J.2): — An array subscript is out of range, even if an object is apparently accessible with the
Using Boost 1.43 and GCC 4.4.3, the following code boost::bind(&SomeObject::m开发者_Go百科emberFunc, this, _1));
