Most types size and alignment is specified in the intel system v abi specifications. Ia64 itanium not to be confused with x8664 amd64 is a family of 64bit intel microprocessors based on vliw with explicit instructionlevel parallelism, in which the compiler decides which instructions to execute in parallel.

Virtual table layout general a virtual table vtable is a table of information used to dispatch virtual functions, to ac.
Introduction in this document, we provide a number of code examples as illustration or tests for the abi specifications. In computer software, an application binary interface abi is an interface between two binary program modules. Compared to the arm, lower blood pressure in the leg suggests blocked arteries due to peripheral artery disease pad. As an abi, it gives precise rules for implementing the language, ensuring that separatelycompiled parts of a program can successfully interoperate. Pavel shved institute for system programming, ras email.
All fields are compressed using the leb128 encoding described in section 7.

Moblin was a mobile linux project which offered a compliance model derived from lsb. The ankle brachial index is used to estimate if a person is subjected to the peripheral artery disease pad. This section defines the unwind library interface, expected to be provided by any itanium psabicompliant system. Itanium is a trademark or registered trademark of intel corporation or its. Sweeneys formulation, return counting could be done. These details are defined as the compiler application binary interface, or abi. Its a base address for data statically allocated by executables, and the itanium architecture has a register just for it. Although it was initially developed for the itanium architecture, it is not platformspecific and can be layered portably on top of an arbitrary c abi.

Lu1, david l kreitzer2, milind girkar3, zia ansari4 based on system v application binary interface. The test is performed by measuring the blood pressure bp in lower legs and arms and is calculated by dividing the systolic pressure in ankles with systolic pressure in arms. Code and implementation examples revised 5 september 2000. For the 64bit itanium abi, it will be unsigned int 32 bits. Its purpose is to establish a standard binary interface for application programs on. Contribute to itanium cxxabicxxabi development by creating an account on github. Many details of the abi cannot be changed without breaking compatibility in some way, and we cannot accept proposals to make such changes.
