Macro Definition Documentation

#define COMPILE_TIME_ASSERT ( cond ) extern int CTAssert[(cond) ? 1 : -1]

Definition at line 38 of file APFloat.cpp.

#define PackCategoriesIntoKey	(	_lhs,
		_rhs
	)	((_lhs) * 4 + (_rhs))

A macro used to combine two fcCategory enums into one key which can be used in a switch statement to classify how the interaction of two APFloat's categories affects an operation.

TODO: If clang source code is ever allowed to use constexpr in its own codebase, change this into a static inline function.
