You can adjust the Intel® C++ Compiler's optimization for a particular application by experimenting with memory and interprocedural optimizations.
Enter the -Qoption option with the applicable keywords to select particular inline expansions and loop optimizations. The option must be entered with a -ip or -ipo specification, as follows:
-ip [-Qoption,tool,opts]
where:
tool is any of the components used to specify the various stages from preprocessing to compilation, which include the linker and assembler.
opts is any of the applicable optimization specifiers for the compilation stage defined in tool.
You can also simultaneously refine memory and interprocedural optimizations by placing a particular specifier for both options in one -Qoption entry. The compiler performs interprocedural optimizations before performing memory-access optimizations.
