Description
Bottom rule

XL C/C++ for z/VM V1.2 is a highly productive and powerful development environment for building C and C++ applications. This compiler is a critical element as customer business applications, customer server applications, ISV applications, and internal IBM componentry are being written in both C and C++.

1999 C Standard

The XL C/C++ for z/VM V1.2 program builds on official industry standards, so your code can be ported easily.

The ISO/IEC 9899:1999 International Standard (also known as C99) specifies the form and establishes the interpretation of programs written in the C programming language. Being the second edition of the standard, this update is designed to enhance the capability of the C language, provide clarifications, and incorporate technical corrections to the previous edition of the standard. Not all run-time functions and facilities required by the ISO/IEC 9899:1999 International Standard are supported on all the operating system levels that can run this version of the compiler. The availability of system header files provides an indication of the support.

XL C/C++ for z/VM also supports the first edition of the C language standard which is ISO/IEC 9899:1990 (also known as C89).

With representation from the IBM compiler development team on the ANSI C committee, IBM is in a position to understand the latest changes and clarifications to the C programming language standard.

The C99 standard offers a number of additional language functions including:

  • Long Long
  • Bool
  • Pragma operator
  • Initializer allow con
  • Empty new argument
  • Macro with variable number of args
  • Inline function specifier
  • Complex

This international standard is designed to promote the portability of C programs among a variety of implementations.

The LANGLVL compiler option has been enhanced to support all of the available language levels that you can use to compile your code within XL C/C++ for z/VM. Your code can conform to the latest C99 standard, use language extensions to C99, or conform to the previous C89 standard. XL C/C++ for z/VM offers you the flexibility to compile your code to the language level that you require.

Compiler Optimization - OPTIMIZE(3)

XL C/C++ for z/VM V1.2 includes the benefits of IBM compiler optimization technology. Through compiler options, directives, and pragmas, z/VM programmers are offered a number of ways to optimize their code. XL C/C++ for z/VM V1.2 introduces the new and higher optimization level OPTIMIZE(3) or Opt(3). Opt(3) provides the compiler's highest and most aggressive level of optimization. Opt(3) is recommended when the desire for run-time improvement outweighs the concern for minimizing compilation resources. Opt(3) introduces additional options and pragmas to help programmers improve their application performance including the Loop Unrolling option and pragmas and a number of new built-in functions. Using the Opt(0), Opt(2) and Opt(3) options, you can obtain optimization levels that run from comprehensive low-level optimizations to more extensive optimizations.

High Order Transformation (HOT) Option

The new HOT option allows for high-order transformations, which are optimizations that specifically improve performance for loops through techniques such as interchange, fusion and unrolling.

__attribute__((aligned(n))) Keyword

A new keyword is introduced to specify the alignment of a variable. This will help improve performance and aid in the porting of applications to z/VM.

IBM Electronic Services
Bottom rule

IBM has transformed its delivery of hardware and software support services to help you achieve higher system availability. Electronic Services is a Web-enabled solution that offers an exclusive, no-additional-charge enhancement to the service and support available for IBM servers. These services are designed to provide the opportunity for greater system availability with faster problem resolution and preemptive monitoring. Electronic Services comprises two separate, but complementary, elements: Electronic Services news page and Electronic Services Agent.

The Electronic Services news page is a single Internet entry point that replaces the multiple entry points traditionally used to access IBM Internet services and support. The news page enables you to gain easier access to IBM resources for assistance in resolving technical problems.

The Electronic Service Agenttm is no-additional-charge software that resides on your server. It monitors events and transmits system inventory information to IBM on a periodic, client-defined timetable. The Electronic Service Agent automatically reports hardware problems to IBM. Early knowledge about potential problems enables IBM to deliver proactive service that may result in higher system availability and performance. In addition, information collected through the Service Agent is made available to IBM service support representatives when they help answer your questions or diagnose problems. Installation and use of IBM Electronic Service Agent for problem reporting enables IBM to provide better support and service for your IBM server.
