   architecture processor. However, if your application uses Intel® Integrated Performance Primitives or Intel® Threading Building Blocks, executing the application will require a processor supporting the Intel® SSE2 instructions. Compiling very large source files (several thousands of lines) using advanced optimizations such as -O3, -ipo and -openmp, may require substantially larger amounts of RAM.
PAGE 9
1.7 Japanese Language Support Intel compilers provide support for Japanese language users (when the combined JapeneseEnglish installation is used). Error messages, visual development environment dialogs and some documentation are provided in Japanese in addition to English. By default, the language of error messages and dialogs matches that of your operating system language selection. Japanese-language documentation can be found in the ja_JP subdirectory for documentation and samples.

Note that there are several different downloadable files available, each providing different combinations of components. Please read the download web page carefully to determine which file is appropriate for you. You do not need to uninstall previous versions or updates before installing a newer version – the new version will coexist with the older versions. Please do not run the install script as a background process (i.e. running “./install.sh &”). This is not supported. 2.

3.2.13 Static Analysis Feature (formerly “Static Security Analysis” or “Source Checker”) Requires Intel® Inspector XE The “Source Checker” feature, from compiler version 11.1, has been enhanced and renamed “Static Analysis”. The compiler options to enable Static Analysis remain the same as in compiler version 11.1 (for example, -diag-enable sc), but the results are now written to a file that is interpreted by Intel® Inspector XE rather than being included in compiler diagnostics output. 3.

current file directory as the first search directory for includes with quotes as in "#include "file"". Enforce same code to be executed regardless of data alignment with –no-optdynamic-align By default, the compiler may generate multiple code paths to execute depending on the alignment of data in order to improve performance which may affect the consistency of floatingpoint calculations. To disable this behavior, use –no-opt-dynamic-align 3.3.5 3.3.

To specify the older default of generic IA-32, specify –mia32 “asm” keyword no longer accepted with –std=c99 in Intel® C++ Compiler 15.0 for Linux* When using –std=c99, the asm keyword will not be recognized starting with the Intel C++ Compiler 15.0. This matches current gcc behavior. Use –std=gnu99 to recognize the asm keyword while maintaining C99 compilation. 3.4.3 3.5 Known Issues 3.5.1.

If you have already created a static analysis result that was affected by this issue and you are able to open that result in the Intel® Inspector XE GUI, then you can hide the undesired messages as follows:  The messages you will want to suppress are “Arg count mismatch” and “Arg type mismatch”. For each problem type, do the following:  Click on the undesired problem type in the Problem filter. This hides all other problem types.

4.2 Using GNU* GDB GNU* GDB provided with Intel® Parallel Studio XE 2015 comes in different versions:   IA-32/Intel® 64 debugger: Debug applications natively on IA-32 or Intel® 64 systems with gdb-ia on the command line. A standard Eclipse* IDE can be used for this as well if a graphical user interface is desired. Intel® Xeon Phi™ coprocessor debugger: Debug applications remotely on Intel® Xeon Phi™ coprocessor systems.
PAGE 27
  The link between the two debuggers will be kept alive. The Intel® MIC Architecture-side debugger will stay connected to the debug agent and the application will remain loaded in the CPU-side debugger, including all breakpoints that have been set. At this point, both debugger windows can safely be closed. 4.4.3 Intel® MIC Architecture-side debugger asserts on setting source directories Setting source directories in the GNU* GDB might lead to an assertion.

5.1.1 Integration notes If you already have the proper versions of Eclipse, CDT and a functional JRE installed and configured in your environment, then you can add the Intel C++ Eclipse Product Extension to your Eclipse Platform, as described in the section, below, entitled How to Install the Intel C++ Eclipse Product Extension in Your Eclipse Platform.
PAGE 29
5.3 How to Obtain and Install Eclipse, CDT and a JRE Eclipse is a Java application and therefore requires a Java Runtime Environment (JRE) to execute. The choice of a JRE is dependent on your operating environment (machine architecture, operating system, etc.) and there are many JRE's available to choose from. A package containing both Eclipse 4.3 and CDT 8.2 is available from: http://www.eclipse.org/downloads/ Scroll down to find “Eclipse IDE for C/C++ Developers”.

also occur if the software is installed from the root account at the system level, but executed by less privileged user accounts. The cause for this failure is that a more granular level of security has been implemented on Fedora, but this new security capability can adversely affect access to system resources, such as dynamic libraries. This new SELinux security capability may require adjustment by your system administrator in order for the compiler installation to work for regular users. 5.
