Glossary
absolute pathname. A pathname that begins with a slash (/) character and is resolved
beginning with the root directory. Contrast with relative pathname.
accelerate. To speed up emulated execution of a TNS object file by applying the
Accelerator on TNS/R systems or the Object Code Accelerator (OCA) on TNS/E
systems before running the object file.
accelerated mode. See TNS accelerated mode.
Accelerator mode. The TNS/R operational environment in which an object file containing
MIPS RISC instructions (called the MIPS region) executes. Contrast with TNS/R native
object code.
accelerated object code. The MIPS RISC instructions (called the MIPS region) that result
from processing a TNS object file with the Accelerator or the Intel Itanium instructions
(called the Itanium region) that result from processing a TNS object file with the Object
Code Accelerator (OCA).
accelerated object file. A TNS object file that, in addition to its TNS instructions (in the
TNS region) and symbol information (in the symbol region), has been augmented
either by the Accelerator with equivalent but faster MIPS RISC instructions (in the
MIPS region) or the Object Code Accelerator (OCA) with equivalent but faster Intel
Itanium instructions (in the Itanium region), or both.
Accelerator. A program optimization tool that processes a TNS object file and produces an
accelerated object file that also contains equivalent MIPS RISC instructions (called the
MIPS region). TNS object code that is accelerated runs faster on TNS/R processors
than TNS object code that is not accelerated. See also TNS Object Code Accelerator
(OCA).
aligned. In TNS/R native mode, a data item is aligned if its address is a multiple of its size;
for example, a 4-byte data item is aligned if its address is a multiple of 4.
alternate file-reference model. The method of tracking, maintaining, and referring to files
that uses file descriptors to denote files. See ANSI file-reference model.
ANSI file-reference model. The method of tracking, maintaining, and referring to files that
uses FILE pointers to denote files. See also alternate file-reference model.
API. See application program interface.
application program interface (API). A set of functions or procedures that are called by an
application program to communicate with other software components.
binding. The operation of collecting, connecting, and relocating code and data blocks from
one or more separately compiled TNS object files to produce a target object file.
