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 ...
In computer programming, a bitwise operation operates on a bit string, a bit array or a binary numeral (considered as a bit string) at the level of its individual bits.It is a fast and simple action, basic to the higher-level arithmetic operations and directly supported by the processor.
How an application should make system calls to the operating system, and if the ABI specifies direct system calls rather than procedure calls to system call stubs, the system call numbers In the case of a complete operating system ABI, the binary format of object files , program libraries, etc.
Julia has ccall keyword to call C (and other languages, e.g., Fortran); [15] while packages, providing similar no-boilerplate support, are available for some languages e.g., for Python [16] (to e.g. provide OO support and GC support), Java (and supports other JDK-languages, such as Scala) and R. Interactive use with C++ is also possible with ...
The calling convention of a given program's language may differ from the calling convention of the underlying platform, OS, or of some library being linked to. For example, on 32-bit Windows, operating system calls have the stdcall calling convention, whereas many C programs that run there use the cdecl calling convention. To accommodate these ...
Binary-code compatibility (binary compatible or object-code compatible) is a property of a computer system, meaning that it can run the same executable code, typically machine code for a general-purpose computer central processing unit (CPU), that another computer system can run.
The SHARE Operating System (1959) for the IBM 709, IBM 7090, and IBM 7094 computers allowed for an loadable code format named SQUOZE. SQUOZE was a compressed binary form of assembly language code and included a symbol table. Modern IBM mainframe operating systems, such as z/OS, have available a symbol table named Associated data (ADATA).
