User and Reference Guide for the Intel® C++ Compiler 14.0
You can use the /Fa option (Windows* OS) or -S and -o options (Linux* OS and OS X*) options to specify an alternate name for an assembly file. The compiler generates an assembly file named myasm.asm (Windows* OS) or myasm.s (Linux* OS and OS X*) :
// (Linux* OS and OS X*) icpc -S -omyasm.s x.cpp
// (Windows* OS) icl /Famyasm x.cpp
