/EHc extern "C" defaults to nothrow     
/fp:<except[-]|fast|precise|strict> choose floating-point model:
    except[-] - consider floating-point exceptions when generating code
    fast - "fast" floating-point model; results are less predictable
    precise - "precise" floating-point model; results are predictable
    strict - "strict" floating-point model (implies /fp:except)
/Qfast_transcendentals generate inline FP intrinsics even with /fp:except

/RTCc Convert to smaller type checks    /RTCs Stack Frame runtime checking
/RTCu Uninitialized local usage checks  
/clr[:option] compile for common language runtime, where option is:
    pure - produce IL-only output file (no native executable code)
    safe - produce IL-only verifiable output file
    oldSyntax - accept the Managed Extensions syntax from Visual C++ 2002/2003
    initialAppDomain - enable initial AppDomain behavior of Visual C++ 2002
    noAssembly - do not produce an assembly
/Gd __cdecl calling convention          /Gr __fastcall calling convention
/Gz __stdcall calling convention        /GZ Enable stack checks (/RTCs)
/QIfist[-] use FIST instead of ftol()   
/hotpatch ensure function padding for hotpatchable images
/arch:<SSE|SSE2|AVX> minimum CPU architecture requirements, one of:
    SSE - enable use of instructions available with SSE enabled CPUs
    SSE2 - enable use of instructions available with SSE2 enabled CPUs
    AVX - enable use of Intel(R) Advanced Vector Extensions instructions
/Qimprecise_fwaits generate FWAITs only on "try" boundaries, not inside "try"
/Qsafe_fp_loads generate safe FP loads
