Identifier "simd" may be treated as reserved attribute keyword, resulting in compiler errors and "warning #2621: attribute "simd" does not apply here"

Reference Number: DPD200240885

Version: Intel® C++ Composer XE 2013 Update 2 (Intel® C++ Compiler XE 13.1.0)

Operating System: Windows* and Linux*

Problem Description:

If the word "simd" is used as an identifier in C/C++ code (for example, as a typename, or as a function parameter name), there is the chance that the compiler may treat this identifier as a reserved attribute keyword and you will then run into compilation errors. This issue should only result in compilation errors. Link-time or runtime problems are not expected. An example follows:

$ cat test-simd.cpp
void foo(float * simd);
$ icc -V -c test-simd.cpp
