The source operand can be either an XMM register (xmm2) or a memory address (m64). When the source operand is an XMM register, the lower half of the register is used in the operation. When the source operand is a memory address, it is assumed to be the address of an 8-byte region, the value at which is used in the operation.
GCC is licensed under the GNU General Public License version 3. [84] The GCC runtime exception permits compilation of proprietary programs (in addition to free software) with GCC headers and runtime libraries. This does not impact the license terms of GCC source code. [85]
It may be specified this way because the standard does not specify that the internal representation of the null pointer is at address zero. Therefore the difference between the member address and the base address needs to be made. Some modern compilers (such as GCC) define the macro using a special form (as a language extension) instead, e.g. [3]
Registers 2 and 3 are used for parameter passing and return values; Registers 4 and 5 are also used for parameter passing; Register 6 is used for parameter passing, and must be saved and restored by the callee; Registers 7 through 13 are for use by the callee, and must be saved and restored by them; Register 14 is used for the return address
POD return values 33–64 bits in size are returned via the EAX:EDX registers. Non-POD return values or values larger than 64-bits, the calling code will allocate space and passes a pointer to this space via a hidden parameter on the stack. The called function writes the return value to this address. Stack aligned on 4-byte boundary. stdcall ...
Intrinsic functions are often used to explicitly implement vectorization and parallelization in languages which do not address such constructs. Some application programming interfaces (API), for example, AltiVec and OpenMP, use intrinsic functions to declare, respectively, vectorizable and multiprocessing-aware operations during compiling.
The NBA All-Star Weekend could also include a variation of last season's NBA versus WNBA 3-point challenge which featured Golden State's Stephen Curry and Sabrina Ionescu of the New York Liberty.
32-bit compilers emit, respectively: _f _g@4 @h@4 In the stdcall and fastcall mangling schemes, the function is encoded as _name@X and @name@X respectively, where X is the number of bytes, in decimal, of the argument(s) in the parameter list (including those passed in registers, for fastcall).
