Profiling Torque with VTune

by Kuju Manila · in Torque Game Engine · 12/13/2007 (9:12 pm) · 6 replies

First of all, I know already that Torque has a built-in profiler. But what I wanted is to profile Torque itself with VTune.

Now, I need help in marrying Intel VTune with Torque. That is, I want to make use of VTune's Call Graph analysis to Torque. However, that is not possible without compiling the Torque Engine with the /FIXED:NO command line option. Whenever I haved that option added in the command line of the Torque Demo VC++ project, I get compilation errors such as:

1>volLight.cc
1>..\engine\lightingSystem\volLight.cc : fatal error C1083: Cannot open include file: 'XED:NO': No such file or directory
1>sgScenePersist.cc
1>..\engine\lightingSystem\sgScenePersist.cc : fatal error C1083: Cannot open include file: 'XED:NO': No such file or directory
1>sgSceneLightingTerrain.cc
1>..\engine\lightingSystem\sgSceneLightingTerrain.cc : fatal error C1083: Cannot open include file: 'XED:NO': No such file or directory
1>sgSceneLightingInterior.cc

1>sgSceneLighting.cc
1>..\engine\lightingSystem\sgSceneLighting.cc : fatal error C1083: Cannot open include file: 'XED:NO': No such file or directory
1>sgObjectShadows.cc
1>..\engine\lightingSystem\sgObjectShadows.cc : fatal error C1083: Cannot open include file: 'XED:NO': No such file or directory
1>sgMissionLightingFilter.cc
1>..\engine\lightingSystem\sgMissionLightingFilter.cc : fatal error C1083: Cannot open include file: 'XED:NO': No such file or directory
1>sgLightObject.cc
1>..\engine\lightingSystem\sgLightObject.cc : fatal error C1083: Cannot open include file: 'XED:NO': No such file or directory
1>sgLightMap.cc
1>..\engine\lightingSystem\sgLightMap.cc : fatal error C1083: Cannot open include file: 'XED:NO': No such file or directory

Note.. the AFX codes also has the same error... the ones above are just a selection. But in reality, it's all over.

I need help in how to compile Torque with the /FIXED:NO option as required by VTune to make use of Call Graph.

Hm, i've compiled TGE 1.3 and gotten it to work w/ vtune's callgraph,
but i'm unfamiliar with the /FIXED:NO option.
it took some futzing but as i recall i just compiled TGE with symbols and let vTune do its thing.
i'll try to check on the exact process tomorrow.

I don't know the command line switches, but just from looking at that, it looks like /FI is "force include" and it's using the rest of the command as the argument, so you are force including "XED:NO".

Shot in the dark.

Not sure it'll help, but
here are screenshots of the VS settings which worked to get a callgraph-able release build.
(particular libraries and such censored, sorry ;)

Oh crap. Actually after posting this, I've found the solution to the problem and I immediately requested deletion of this thread... seems it did not apply. Anyway, the problem was i'm placing the /FIXED:NO option on the command line of the compiler not linker! Haha stupid me. Anyway, I hope other Vtune users will find this useful.

I didn't try VTunes and I don't know about most compiller/linker command line switches neither, but I just tried to compile the engine with Intel C Plus Plus Compiler v10.1.013 and the result is
1>Torque Engine - 0 error(s), 876 warning(s)
Maybe some GG employee might want to check those warning cause most of them seem stupid programming errors. The game still works fine, and I don't get any FPS boost.

There are far more than 876 stupid programming errors in Torque.

Most of the warnings are related to data conversions, both safe and unsafe. The default practice for getting rid of errors in Torque has been to turn down the warning level. For Torque2 we turned it up, and fixed the warnings.
