Source-code compatibility (source-compatible) means that a program can run on computers (or operating systems), independently of binary-code compatibility and that the source code is needed for portability. [1] The source code must be compiled before running, unless the computer used has an interpreter for the language at hand. [2]
Benchmarks are occasionally run on Wine to compare it to Windows NT-based operating systems. [24] Even on similar systems, the details of implementing a compatibility layer can be quite intricate and troublesome; a good example is the IRIX binary compatibility layer in the MIPS architecture version of NetBSD. [25]
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. Source-code compatibility, on the other hand, means that ...
Software compatibility can refer to the compatibility that a particular software has running on a particular CPU architecture such as Intel or PowerPC. [1] Software compatibility can also refer to ability for the software to run on a particular operating system. Very rarely is a compiled software compatible with multiple different CPU ...
A compatibility mode is a software mechanism in which a software either emulates an older version of software, or mimics another operating system in order to allow older or incompatible software or files to remain compatible with the computer's newer hardware or software. Examples of the software using the mode are operating systems and ...
Because a program normally relies on such factors, different systems will typically not run the same machine code, even when the same type of processor is used. A processor's instruction set may have fixed-length or variable-length instructions. How the patterns are organized varies with the particular architecture and type of instruction.
Copy all bits of the source argument, then clear the lowest set bit. Equivalent to dst = (src-1) AND src: BMI2 Bit Manipulation Instruction Set 2: BZHI ra,r/m,rb: VEX.LZ.0F38 F5 /r: Zero out high-order bits in r/m starting from the bit position specified in rb, then write result to rd. Equivalent to ra = r/m AND NOT(-1 << rb[7:0]) Haswell ...
[11] C++ is also more strict in conversions to enums: ints cannot be implicitly converted to enums as in C. Also, enumeration constants (enum enumerators) are always of type int in C, whereas they are distinct types in C++ and may have a size different from that of int. [needs update] In C++ a const variable must be initialized; in C this is ...
