Description
The VisualAge C++,V6.0 for Linux on pSeries software is a highly
productive and powerful development environment for building C and C++
applications.
1998 C++ and 1999 C International Standards
VisualAge C++, V6.0 for Linux on pSeries builds on official industry standards, so your code can be ported easily among a variety of implementations.
1999 C Standard: 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. This is the second edition of the standard. This update enhances the capability of the C language, provides clarifications, and incorporates technical corrections to the previous edition of the standard. The language features supported by the C compiler within VisualAge C++, V6.0 for Linux on pSeries is consistent with the specification described in the ISO/IEC 9899:1999 International Standard. The compiler works with a run-time environment that supports the standard to form a conforming implementation.
The C99 Standard offers a number of additional language functions over the first edition (C89) of the standard and include:
- Long Long
- Bool
- Pragma operator
- Initializer allow con
- Empty new argument
- Macro with variable number of args
- Inline function specifier
- Complex
The -qlanglvl compiler option allows you to choose from the available language levels that you can use to compile your code within VisualAge C++. Your code can conform to the latest C99 Standard, use extensions to C99, or conform to the previous C89 Standard. VisualAge C++ offers you the flexibility to compile your code to the language level that you need.
1998 C++ Standard:
The ISO/IEC 14882:1998 International Standard (also known as
Standard C++) specifies the form and establishes the interpretation of
programs written in the C++ programming language. This International
Standard promotes the portability of C++ programs among a variety of
implementations. ISO/IEC 14882:1998 is the first formal definition of
the C++ language. The C++ compiler within VisualAge C++, V6.0 for Linux
on pSeries supports the 1998 ISO/IEC Standard. In addition, VisualAge
C++ supports a number of the latest approved clarifications from the
standards committee bringing the C++ compiler within VisualAge C++, V6.0
for Linux on pSeries to the latest level of the standard.
OpenMP
The OpenMP is an industry specification describing a common set of APIs that support multiplatform symmetric multiprocessing (SMP) programming in C, C++, and FORTRAN on all architectures, including UNIX® platforms. Jointly defined by a group of major computer hardware and software vendors, including IBM, OpenMP is a portable, scalable programming model that provides SMP programmers with a simple and flexible interface for developing shared-memory parallel applications for platforms ranging from the desktop to the supercomputer.
VisualAge C++, V6.0 for Linux on pSeries provides full support for the OpenMP Industry Specification V1.0. For more information about the OpenMP Specification, visit the OpenMP Web site at:
Compiler Optimization
VisualAge C++, V6.0 for Linux on pSeries includes the benefits of IBM's compiler optimization technology. Through compiler options, directives, and pragmas, programmers are offered a number of ways to optimize their code. Using the -O2, -O3, -O4, and -O5 options, you can obtain optimization levels that run from comprehensive low-level optimizations to more extensive optimizations that include Interprocedural analysis, loop optimization, and automatic machine tuning. Other options for optimization include:
- -qarch, -qtune, and -qcache that allow you to optimize your application to the POWER3 and POWER4 architecture.
- -qhot allows for high-order transformations, which are optimizations that specifically improve performance of loops through techniques such as interchange, fusion, and unrolling.
- -qipa invokes interprocedural analysis (IPA) that enables the compiler to optimize across different files (whole-program analysis), and can result in significant performance improvements.
- -qpdf (that is profile-directed feedback) uses results from sample program execution to fine tune optimizations in conditional branches and frequently executed code sections.
- -qsmp generates threaded code needed to exploit shared-memory parallel processing leading to high-performance code.
32-bit and 64-bit Support
You can use VisualAge C++, V6.0 for Linux on pSeries to develop 32-bit
and 64-bit applications. VisualAge C++ provides 64-bit pointer and
64-bit addressability support for SMP and serial code. High optimization
levels, interprocedural analysis, and SMP are supported for 64-bit code.
Ease of Porting
VisualAge C++, V6.0 for Linux on pSeries has features that help you port
existing code from AIX or other UNIX-based systems as well as from code
originally written for GNU C/C++. For example, by compiling with the
-qinfo=por option, you can filter the diagnostic messages emitted by the
compiler to show only those that pertain to portability issues. Also a
comprehensive subset of features related to GNU C/C++ are supported by
VisualAge C++, V6.0 for Linux on pSeries. Other GNU C/C++ features are
recognized (accepted and ignored). This will help you minimize the
number of changes that you need to make to your GCC source code to ensure
that it compiles successfully using VisualAge C++, V6.0 for Linux on
pSeries.
Binary Compatibility and Coexistence
VisualAge C++, V6.0 for Linux on pSeries supports the C++ Abstract Binary Interface (ABI), which means that the compiler produces binary or object files that are compatible with those created with the GCC compiler.
VisualAge C++, V6.0 for Linux on pSeries includes the same headers as those used by a GNU compiler residing on the same system. This allows VisualAge C++, V6.0 for Linux on pSeries to achieve binary compatibility with GCC-compiled code. The VisualAge compiler optimizes the program while maintaining binary compatibility with objects produced by GCC V3.2. Additional coexistence features include:
- IBM built-in functions for POWER3 and POWER4 architectures coexist with GNU C built-ins
- Compilation uses the GNU C and C++ header files from the Linux distribution
- Compilation uses the GNU assembler
- Linking uses the GNU linker
- Compiled programs use the GNU C and C++ run-time libraries
- Compiled object files compatible with g++ objects
- Debugging uses the GNU debugger, gdb
- Profiling uses the GNU profiler, gprof
GNU Debugger, gdb
VisualAge C++, V6.0 for Linux on pSeries supports debugging using the GNU
debugger, gdb. This symbolic debugger, which comes with the system,
supports full debugging capability for code without optimization and
partial debugging for code at the -O2 optimization level.
