C++ compiler flags for profiling in Visual Studio

Question

To accurately profile an application, under linux , it is recommended to have optimizations on and debug symbols on via compile options -O2 -g for gcc or g++ . This enables profiling to include the user's C++ code and not point to assembly code instead as possible hotspots, for instance. See for instance, here .

In Visual Studio IDE, for usage of profilers, what are the equivalent compile/linking options?

In Release mode of Visual Studio, under "Whole Program Optimization" property sheet that comes loaded by default, the Debug Information Format gets set to Program Database with command line option /Zi . See image:

Is this the Visual Studio/Windows/MSVC (Cl.exe, MSBuild.exe) equivalent of -O2 -g ? Or are there any other equivalent settings?

ETA: Under the default Visual Studio 2019 release mode settings, the following flags are set:

/permissive- /ifcOutput "x64\Release\" /GS /GL /W3 /Gy /Zc:wchar_t /I"E:\local\boost_1_72_0" /Zi /Gm- /O2 /sdl /Fd"x64\Release\vc142.pdb" /Zc:inline /D "_MBCS" /errorReport:prompt /WX- /Zc:forScope /Gd /Oi /MD /FC /Fa"x64\Release\" /EHsc /nologo /Fo"x64\Release\" /FA /Fp"x64\Release\windows.pch" /diagnostics:column 

Answer 1

Have a look at the project properties, under C++ optimization. The IDE tells you everything.
