C/C++ COMPILER OPTIONS
-OPTIMIZATION-
/O1 minimize space /O2 maximize speed
/Ob<n> inline expansion (default n=0) /Od disable optimizations (default)
/Og enable global optimization /Oi[-] enable intrinsic functions
/Os favor code space /Ot favor code speed
/Ox maximum optimizations /Oy[-] enable frame pointer omission
-CODE GENERATION-
/GF enable read-only string pooling /Gm[-] enable minimal rebuild
/Gy[-] separate functions for linker /GS[-] enable security checks
/GR[-] enable C++ RTTI /GX[-] enable C++ EH (same as /EHsc)
/EHs enable C++ EH (no SEH exceptions) /EHa enable C++ EH (w/ SEH exceptions)
/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
/GL[-] enable link-time code generation /GA optimize for Windows Application
/Ge force stack checking for all funcs /Gs[num] control stack checking calls
/Gh enable _penter function call /GH enable _pexit function call
/GT generate fiber-safe TLS accesses /RTC1 Enable fast checks (/RTCsu)
/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

-PREPROCESSOR-
/AI<dir> add to assembly search path /FU<file> forced using assembly/module
/C don't strip comments /D<name>{=|#}<text> define macro

/vd{0|1|2} disable/enable vtordisp /vm<x> type of pointers to members
/Zc:arg1[,arg2] C++ language conformance, where arguments can be:
forScope[-] - enforce Standard C++ for scoping rules
wchar_t[-] - wchar_t is the native type, not a typedef
auto[-] - enforce the new Standard C++ meaning for auto
