executable loader造句
例句与造句
- C9h is never appropriate as the first byte of a program for any x86 processor ( it has different meanings for different generations, but is never a meaningful first byte ); the executable loader in some versions of DOS rejects COM files that start with C9h, avoiding incorrect operation.
- When Microsoft faded out support for 16-bit code in Windows by no longer including NTVDM in 64-bit editions of the operating system, the executable loader was modified to recognize some specific 16-bit stub launchers / installers and replace them on-the-fly with equivalent code stubs running on 64-bit processors.
- Under CP / M 3, if the first byte of a COM file is C9h, there is a 256-byte header; since C9h corresponds to the 80186 and therefore not used as the first instruction in a valid program, the executable loader in some versions of DOS rejects COM files that start with C9h, avoiding a crash.
- In order to indicate this, the first byte in the header is set to C9h, which works both as a signature identifying this type of COM file to the CP / M 3.0 executable loader, as well as a RET instruction for 8080-compatible processors which leads to a graceful exit if the file is executed under older versions of CP / M-80.
- Examples can be found in MS-DOS / PC DOS; when running on 286 or higher processors, the resident executable loader contains code specially designed to detect and fix certain widespread applications and stub loaders ( such as programs linked with older versions of Microsoft's EXEPACK or Rational Systems'386 DOS extenders ) by patching the loaded program image before executing it, or where DOS patches Windows ( WINA20.386 ) Over the course of development, DR-DOS also had to be modified to not only emulate many undocumented peculiarities of MS-DOS / PC DOS, but also actual bugs in the kernel and several drivers to make certain other drivers and applications run on DR-DOS, when they were tested on specific versions of MS-DOS only.
- It's difficult to find executable loader in a sentence. 用executable loader造句挺难的
