The compiler does not substitute a call to _intel_fast_calloc() for a call to calloc(). |
This option tells the compiler to substitute a call to_intel_fast_calloc() for a call to calloc().
This option may increase the performance of long-running programs that use calloc() frequently. It is recommended for these programs over combinations of options -inline-calloc and -qopt-malloc-options=3 because this option causes less memory fragmentation.
Many routines in the LIBIRC library are more highly optimized for Intel® microprocessors than for non-Intel microprocessors.
