Compiler Options Listed by Category


This article contains a categorical list of compiler options. For an alphabetical list, see Compiler Options Listed Alphabetically.





Creates small code.


Creates fast code.


Controls inline expansion.


Disables optimization.


Uses global optimizations.


Generates intrinsic functions.


Favors small code.


Favors fast code.


Uses maximum optimization (/Ob2gity /Gs).


Omits frame pointer. (x86 only)


Produces code that is optimized for a specified architecture, or for a range of architectures.

Code Generation




Use SSE or SSE2 instructions in code generation. (x86 only)


Produces an output file to run on the common language runtime.


Specifies the model of exception handling.


Specifies floating-point behavior.


Optimizes for Windows applications.


Uses the __cdecl calling convention. (x86 only)


Activates stack probes.


Enables string pooling.


Calls hook function _penter.


Calls hook function _pexit.


Enables whole program optimization.


Enables minimal rebuild.


Enables run-time type information (RTTI).


Uses the __fastcall calling convention. (x86 only)


Checks buffer security.


Controls stack probes.


Supports fiber safety for data allocated by using static thread-local storage.


Adds control flow guard security checks.


Uses the __vectorcall calling convention. (x86 and x64 only)


Enables whole-program global data optimization.


Enables synchronous exception handling.


Enables function-level linking.


Enables fast checks. (Same as /RTC1)


Uses the __stdcall calling convention. (x86 only)

Uses integer move instructions for floating-point values and disables certain floating point load optimizations.

/Qvec-report (Auto-Vectorizer Reporting Level)

Enables reporting levels for automatic vectorization.


Enables run-time error checking.


Selects how the volatile keyword is interpreted.
