Description
Description
Intel C++ compiler (icpc) should be supported, together with the "-xHost" compiler option to generate instructions for the highest instruction set and processor available on the compilation host machine.
Example
In make/default_compiler_options set
CC=icpc
Currently, since the optimization flag only sets the integer optimization level, there is no mechanism for adding other optimization options (e.g. for code generation).
Expected Output
Example with Intel Composer XE 2019u1:
Stan Math makefile:
Current configuration:
- OS_TYPE (Operating System): linux
- CC (Compiler): icpc
- CC_TYPE intel
- Compiler version: 19.0.1.144 20181018
- O (Optimization Level): 3
Current Version:
v2.18.1

Research direction
Start in make/default_compiler_options and trace how the compiler is identified and optimization options are assembled. Check how an icpc build should report CC_TYPE and compiler version, and how -xHost would be supplied. Done means the example configuration produces the expected Intel compiler output and supports the requested option.
