Compiler Options Listed Alphabetically

The following is a comprehensive alphabetical list of compiler options. For a categorical list, see the Compiler Options Listed by Category.

Option Purpose
@ Specifies a response file

/AI Specifies a directory to search to resolve file references passed to the #using directive
/arch Use SSE or SSE2 instructions in code generation
/C Preserves comments during preprocessing
/c Compiles without linking
/clr Enables Managed Extensions for C++ and produces an output file to run on the common language runtime
/D Defines constants and macros
/E Copies preprocessor output to standard output
/EH Specifies the model of exception handling
/EP Copies preprocessor output to standard output

/Fp Specifies a precompiled header file name
/FR
/Fr
Generates browser files
/FU Forces the use of a file name as if it had been passed to the #using directive
/Fx Merges injected code with source file
/G3 Optimizes code to favor the 386 processor. Phased out in Visual C++ 5.0, the compiler will ignore this option
/G4 Optimizes code to favor the 486 processor. Phased out in Visual C++ 5.0, the compiler will ignore this option

/Gd Uses the __cdecl calling convention
/Ge Activates stack probes
/GF
/Gf
Enables string pooling
/GH Calls hook function _pexit
/Gh Calls hook function _penter

/GR Enables run-time type information (RTTI)
/Gr Uses the __fastcall calling convention
/GS Buffers security check
/Gs Controls stack probes
/GT Supports fiber safety for data allocated using static thread-local storage
/GX Enables synchronous exception handling
/Gy Enables function-level linking
/GZ Same as /RTC1
/Gz Uses the __stdcall calling convention
/H Restricts the length of external (public) names
/HELP Lists the compiler options
/I Searches a directory for include files
