Excuse me for my jumping late into the thread, but what are the situations where one would want to use a BOOST_ASSERT with __assume instead of assert?
__assume on MSVC passes hints to the compiler for optimization, it assumes the expression is always true. So that a function like this: int f(int x) { __assume(x == 0) return x; } is optimized by the compiler and just returns 0, without checking for x. It really seems an interesting opportunity for using already assertions for optimizations.
