| Description |
|
IBM XL C/C++ for Linux, V13.1 continues to deliver additional functionality and enhancements including support for the latest IBM POWER8 technology. These features are designed to improve application performance and capability.
Exploitation of the new IBM POWER8 technology
A key strength of XL C/C++ for Linux is its ability to generate highly optimized code for execution on IBM Power Systems. The performance gain from years of IBM compiler optimization experience can be seen in the release-to-release compiler improvements from the development of the IBM POWER4 processors through to the IBM POWER5, IBM POWER5+, IBM POWER6®, IBM POWER6+™, IBM POWER7®, and IBM POWER7+™ processors. With XL C/C++ for Linux, V13.1, compiler support now includes exploitation of the latest IBM Power Systems built with the POWER8 architecture and processor.
New architechure and tune compiler options for POWER8 technology
The -qarch compiler option specifies the processor architecture for which code is generated. The -qtune compiler option tunes instruction selection, scheduling, and other architecture-dependent performance enhancements to run best on a specific hardware architecture. With this new release of XL C/C++ for Linux, V13.1, new architecture and tune compiler suboptions are added to specify code generation for the POWER8 processor architecture. -qarch=pwr8 instructs the compiler to produce code that can fully exploit the POWER8 architecture. -qtune=pwr8 enables optimizations specifically for the Power Systems with the POWER8 design and processor.
Compiler built-in functions for POWER8 technology
New built-in functions unlock POWER8 architecture instructions to enable you to have direct access to POWER8 features at the application level.
New built-in functions are added to support the following POWER8 features:
- POWER8 built-in functions for vector processing
- POWER8 binary-coded decimal functions
- POWER8 cryptography functions
- POWER8 quad-word arithmetic functions
- POWER8 load-and-reserve and store condition instructions
- POWER8 cache and data prefetch control functions
- POWER8 transactional memory functions
- POWER8 prefetch functions
Mathematical Acceleration Subsystem (MASS) Library enhancements
The MASS libraries are an accelerated set of frequently used mathematical functions that provide improved performance over the corresponding standard system library functions. These highly tuned MASS libraries are enhanced to support the POWER8 technology:
- The vector MASS library contains vector functions that are tuned for the POWER8 architecture. These functions can be used in either 32-bit mode or 64-bit mode.
- The MASS SIMD library is tuned for the POWER8 processor.
IBM Advance Toolchain 7.0 support
XL C/C++ for Linux, V13.1 fully supports IBM Advance Toolchain 7.0, a set of open source development tools and runtime libraries. With IBM Advance Toolchain, you can take advantage of the latest Power hardware features on Linux, especially the tuned libraries.
C11 programming standard
C11 is the latest standard for the C programming language, published as ISO/IEC 9899:2011. With V13.1, partial support for the C11 standard continues with the implementation of the following features:
- The typedef redeclaration
- Using the typedef redeclaration, you can redefine a name that is a previous typedef name in the same scope to refer to the same type. The XL C compiler supports all types, including a variable modified type.
- Generic selection
- Generic selection provides a mechanism to choose an expression according to a given type name at compile time. A common usage is to define type generic macros.
C++11 programming standard
C++11 is the latest standard for the C++ programming language, published as ISO/IEC 14882:2011. With V13.1, partial support for the C++11 standard continues with the implementation of the following features:
- Defaulted and deleted functions
- This feature introduces two new forms of function declarations to define explicitly defaulted functions and deleted functions. For the explicitly defaulted functions, the compiler generates the default implementations, which are more efficient than manually programmed implementations. The compiler disables the deleted functions to avoid calling unwanted functions.
You can use the -qlanglvl=defaultanddelete option to enable this feature.

- Files that are ultimately included by the files in the standard search paths for compiler and system header files.
The following -qinfo suboptions are added or updated:
- -qinfo=mt suboption notifies you about potential places where synchronization is needed.
- -qinfo=unset suboption detects automatic variables that are used before they are set, and flags them with informational messages at compile time.
- The following suboptions for -qlanglvl are added or updated:
- -qlanglvl=defaultanddelete suboption enables the defaulted and deleted functions feature with which you can define explicitly defaulted functions whose implementations are generated by the compiler to achieve higher efficiency. With this feature, you can also define deleted functions whose usages are disabled by the compiler to avoid calling unwanted functions.
- -qlanglvl=nullptr suboption enables the nullptr feature. With this feature, you can initialize a null pointer with the nullptr constant. The null pointer can be converted to the pointer type, pointer-to-member type, or bool type. The nullptr constant can be distinguished from the integer 0 for overloaded functions.
- -qpdf1=unique suboption creates a unique PDF file for each process during run time.
- -qprefetch=dscr suboption helps to improve the runtime performance of your applications. You can specify a value for dscr depending on your system architecture.
- -qsimd=auto suboption controls the autosimdization. This option replaces the deprecated -qhot=simd option.
- -qstaticlink=xllibs suboption links in the XL compiler libraries statically.
- The -qtune option default is updated and the following suboptions are added or updated:
- -qtune=pwr7 suboption specifies that optimizations are tuned for the POWER7 or POWER7+ hardware platforms.

- -qvisibility option specifies visibility attributes for entities. Entity visibility attributes describe whether and how entities defined in one module can be referenced or used in other modules. Visibility attributes affect entities with external linkage only, and cannot increase the visibility of other entities.
New and enhanced pragma directives
The #pragma GCC visibility push and #pragma GCC visibility pop directives are the pragma equivalent of the -qvisibility option. These pragma directives are used to specify visibility attributes for external linkage symbols.
Performance and optimization
Entity visibility attributes describe whether and how an entity that is defined in one module can be referenced or used in other modules. By using the visibility attributes for entities, you can get the following benefits:
- Decreasing the size of shared libraries
- Reducing the chance of symbol collision
- Allowing more optimization for the compile and link phases
- Improving the efficiency of dynamic linking

At a basic level, compilers are a bridge between your applications and the hardware architectures on which you run your business. IBM compilers are designed to unleash the full power of IBM processors, including those for the different architectures shipped in the popular IBM Power Systems. IBM compilers now include exploitation of the new POWER8 technology.
IBM compilers are designed to improve programmer productivity. The advanced compilation technology enables programmers to exploit leading edge performance of the new hardware without source code changes. Developers only need to focus on the logic of the applications and let the compiler figure out the best way to transform and optimize the code generation for the systems the application will run on.
Harness the power of parallel computing
Parallel programming with IBM XL C/C++ for Linux exploits the advantages of multiprocessor systems, while maintaining full binary compatibility with existing single processor systems. With XL C/C++, you can use any of the following to develop your parallelized applications:
- An extensive range of OpenMP directives and non-OpenMP SMP directives
- Message passing interface (MPI)
- The POSIX threads (Pthreads) library module
For high-bandwidth data processing and algorithmic-intensive applications, XL C/C++ for Linux can leverage VMX and VSX instructions and automatic SIMDization to improve program performance. By processing multiple pieces of data at once, your program can run faster, with the added benefit that the source code may not need to be rewritten.
Powerful, no-hassle performance optimization
Your well-written and thoroughly debugged code, fully conformant to its language standard, can take maximum advantage of the optimizing technology in XL C/C++ for Linux. These compiler features are designed to help increase the performance of your applications. The optimization and hardware features in XL C/C++ for Linux can help to improve developer productivity. The compiler can generate code that exploits the leading edge performance in existing and new hardware, often with minimal source code changes.
XL C/C++ for Linux supports several levels of increasingly agressive code transformations. Advanced optimization techniques, such as inter-procedural analysis (IPA) and profile-directed feedback, are available only at high levels of optimization but can result in signifcant performance improvements. IPA analyzes and optimizes your application as a whole, rather than on a file-by-file basis. Profile-directed feedback generates information that instructs the optimizer to focus on tradeoffs that favor code that executes more frequently.
You can get more performance from the IBM Power platform with minimal or no source code changes. You can upgrade to the latest XL C/C++ for Linux compiler, which incorporates the latest advances in optimization and hardware technology support.
Multiple-platform XL C, C++, and Fortran
IBM XL C/C++ for Linux, V13.1 is part of a larger family of IBM XL C, C++, and Fortran compilers, which supports multiple platforms such as IBM AIX®, IBM z/OS® (C/C++), IBM z/VM® (C/C++), IBM Power Systems, Linux on Power, and IBM Blue Gene/Q™.
The modular structure of these compilers delivers optmizations and functionality on all platforms and to all languages. Further, each product derives from a common code base, so features and optimizations are tested in multiple languages on multiple platforms. A common code base, along with compliance with international standards make source-level portability of applications between IBM platforms easier.
Built on a common architecture, XL C, XL C/C++, and XL Fortran compilers promote consistency and reliability on many IBM platforms.
Programming language standards and industry specifications

Electronic Software Update (ESU) orders
ESU is a way for customers to self order their POWER® software release upgrades through the Entitled Software Support (ESS) website without the need to go to their seller to place the upgrade order. Entitled Software Update (ESU) orders for Electronic Software Delivery (ESD), will now be available in all countries. ESU orders for POWER software, including IBM XL C/C++ for Linux, V12.1, will be placed on the Entitled Software Support (ESS) website
Customers should generally select electronic delivery when ordering through ESU, but do have the ability to select physical delivery. Programs ordered for ESD will have the same download images provided as provided on the DVD media shipped for physical orders.
ESU customers placing ESD software orders will receive an email with software order information. The ESU customer will be able to immediately proceed to the Downloads website support for program access, instead of waiting for delivery of a physical package shipped from IBM.
Customers choosing physical delivery will also have the electronic images available for ESD download.

Concurrent User
This program is licensed and charged based upon either the Authorized User or Concurrent User charge metric.
Authorized User
Authorized User is a unit of measure by which the program can be licensed. An Authorized User is a unique person who is given access to the program. The program may be installed on any number of computers or servers and each Authorized User may have simultaneous access to any number of instances of the program at one time. Licensee must obtain separate, dedicated entitlements for each Authorized User given access to the program in any manner directly or indirectly (for example, via a multiplexing program, device, or application server) through any means. An entitlement for an Authorized User is unique to that Authorized User and may not be shared, nor may it be reassigned other than for the permanent transfer of the Authorized User entitlement to another person.
Note: Some programs may be licensed where devices are considered users. In that case, the following applies. Any computing device that requests the execution of or receives for execution a set of commands, procedures, or applications from the program or that is otherwise managed by the program is considered a separate user of the program and requires an entitlement as if that device were a person.
Concurrent User
Concurrent User is a unit of measure by which the program can be licensed. A Concurrent User is a person who is accessing the program at any particular point in time. Regardless of whether the person is simultaneously accessing the program multiple times, the person counts only as a single Concurrent User. The program may be installed on any number of computers or servers, but licensee must obtain entitlements for the maximum number of Concurrent Users simultaneously accessing the program. Licensee must obtain an entitlement for each simultaneous Concurrent User accessing the program in any manner directly or indirectly (for example, via a multiplexing program, device, or application server) through any means.
Note: Some programs may be licensed where devices are considered users. In that case, the following applies. Any computing device that requests the execution of or receives for execution a set of commands, procedures, or applications from the program or that is otherwise managed by the program is considered a separate user of the program and requires an entitlement as if that device were a person.

| Terms and conditions |
|
The information provided in this announcement letter is for reference and convenience purposes only. The terms and conditions that govern any transaction with IBM are contained in the applicable contract documents such as the IBM International Program License Agreement, IBM International Passport Advantage Agreement, and the IBM Agreement for Acquisition of Software Maintenance.
Licensing
IBM International Program License Agreement including the License Information document and Proof of Entitlement (PoE) govern your use of the program. PoEs are required for all authorized use. Part number products only, offered outside of Passport Advantage, where applicable, are license only and do not include Software Maintenance.
This software license includes Software Subscription and Support (also referred to as Software Maintenance).
Agreement for Acquisition of Software Maintenance
The IBM Agreement for Acquisition of Software Maintenance (Z125-6011) applies for Subscription and Support (also referred to as Software Maintenance) and does not require customer signatures.
These programs are licensed under the IBM Program License Agreement (IPLA) and the associated Agreement for Acquisition of Software Maintenance, which provide for support with ongoing access to releases and versions of the program. IBM includes one year of Software Subscription and Support (also referred to as Software Maintenance) with the initial license acquisition of each program acquired. The initial period of Software Subscription and Support (also referred to as Software Maintenance) can be extended by the purchase of a renewal option, if available. These programs have a one-time license charge for use of the program and an annual renewable charge for the enhanced support that includes telephone assistance (voice support for defects during normal business hours), as well as access to updates, releases, and versions of the program as long as support is in effect.
License Information number
L-MCHN-9GPNRY.
The program's License Information will be available for review on the IBM Software License Agreement website
Limited warranty applies
Yes
Limited warranty
IBM warrants that when the program is used in the specified operating environment, it will conform to its specifications. The warranty applies only to the unmodified portion of the program. IBM does not warrant uninterrupted or error-free operation of the program or that IBM will correct all program defects. You are responsible for the results obtained from the use of the program.
IBM provides you with access to IBM databases containing information on known program defects, defect corrections, restrictions, and bypasses at no additional charge. For further information, consult the IBM Software Support Handbook found at
IBM will maintain this information for at least one year after the original licensee acquires the program (warranty period).
Money-back guarantee
If for any reason you are dissatisfied with the program and you are the original licensee, you may obtain a refund of the amount you paid for it, if within 30 days of your invoice date you return the program and its PoE to the party from whom you obtained it. If you downloaded the program, you may contact the party from whom you acquired it for instructions on how to obtain the refund.
For clarification, note that (1) for programs acquired under the IBM International Passport Advantage offering, this term applies only to your first acquisition of the program and (2) for programs acquired under any of IBM's On/Off Capacity on Demand (On/Off CoD) software offerings, this term does not apply since these offerings apply to programs already acquired and in use by you.
Other terms
Volume orders (IVO)
Yes. Contact your IBM representative.
IBM International Passport Advantage Agreement
Passport Advantage applies
Yes, and through the Passport Advantage website at
Software Subscription and Support applies
Yes. Software Subscription and Support (also referred to as Software Maintenance), is now included in the Passport Advantage Agreement. Installation and technical support for the products announced in this announcement is provided by the Software Subscription and Support offering of the IBM International Passport Advantage Agreement. This fee service enhances customer productivity by providing voice or electronic access into the IBM support organizations.
IBM includes one year of Software Subscription and Support with the initial license acquisition of each program acquired. The initial period of Software Subscription and Support can be extended by the purchase of a renewal option.
While your Software Subscription and Support is in effect, IBM provides you assistance for your routine, short duration installation and usage (how-to) questions, and code-related questions. IBM provides assistance via telephone and, if available, electronic access, only to your information systems (IS) technical support personnel during the normal business hours (published prime shift hours) of your IBM support center. (This assistance is not available to your end users.) IBM provides Severity 1 assistance 24 hours a day, every day of the year. For additional details, consult your IBM Software Support Handbook at
Software Subscription and Support does not include assistance for the design and development of applications, your use of programs in other than their specified operating environment, or failures caused by products for which IBM is not responsible under this agreement.
For additional information about the Passport Advantage Agreement, visit the Passport Advantage website at
All distributed software licenses include Software Subscription and Support for a period of 12 months from the date of acquisition, providing a streamlined way to acquire IBM software and assure technical support coverage for all licenses. Extending coverage, for a total of three years from date of acquisition, may be elected.

| Statement of good security practices |
|
IT system security involves protecting systems and information through prevention, detection, and response to improper access from within and outside your enterprise. Improper access can result in information being altered, destroyed, or misappropriated or can result in misuse of your systems to attack others. Without a comprehensive approach to security, no IT system or product should be considered completely secure and no single product or security measure can be completely effective in preventing improper access. IBM systems and products are designed to be part of a comprehensive security approach, which will necessarily involve additional operational procedures, and may require other systems, products, or services to be most effective. IBM does not warrant that systems and products are immune from the malicious or illegal conduct of any party.
