critical impact:

machine/builtins.h - not supported; temporarily available (CrUn388)

HDR Impacts ME Impacts

Problem description

The <machine/builtins.h> header file exists on Tru64 UNIX but not on HP-UX. This header file will be temporarily available in the Tru64 UNIX Migration Environment for HP-UX (Itanium® only).

The <machine/builtins.h> header file contains functions whose names are specially recognized by the compiler (these are similar to intrinsic functions).

The Migration Environment contains Tru64 UNIX APIs, development tools, and commands and utilities to assist you in migrating your applications from Tru64 UNIX to HP-UX.

Solution description

The <machine/builtins.h> header file is in the Tru64 UNIX Migration Environment for HP-UX (Itanium® only).

Applications can use this header file from the Migration Environment. Please note that the Migration Environment is temporary.

Some of the builtins implement spinlocks. For information on implementing spinlocks on HP-UX, see the Implementing Spinlocks on the Intel®Itanium® Architecture and PA-RISC white paper. This paper describes the implementation of spinlocks and fences to guarantee memory consistency for shared memory applications on the Itanium® processor family, as well as on PA-RISC platforms.
