Native DXBC leads to a crash during instrumentation #30

When I instrument the pipelines, my DX12 application crashes. I get the following GPUReshape callstack:

KernelBase.dll!00007ffd6577bdd2() Unknown GRS.Backends.DX12.Layer {5E2507A2-DA03-446F-9F65-7E133DF1276E}.dll!Detail::Break(const char message) Line 52 C++ GRS.Backends.DX12.Layer {5E2507A2-DA03-446F-9F65-7E133DF1276E}.dll!DXBCPhysicalBlockFeatureInfo::Compile() Line 53 C++ GRS.Backends.DX12.Layer {5E2507A2-DA03-446F-9F65-7E133DF1276E}.dll!DXBCPhysicalBlockTable::Compile(const DXCompileJob & job) Line 110 C++ GRS.Backends.DX12.Layer {5E2507A2-DA03-446F-9F65-7E133DF1276E}.dll!DXBCModule::Compile(const DXCompileJob & job, DXStream & out) Line 118 C++ GRS.Backends.DX12.Layer {5E2507A2-DA03-446F-9F65-7E133DF1276E}.dll!ShaderCompiler::CompileShader(const ShaderJob & job) Line 203 C++ GRS.Backends.DX12.Layer {5E2507A2-DA03-446F-9F65-7E133DF1276E}.dll!ShaderCompiler::Worker(void data) Line 103 C++ GRS.Backends.DX12.Layer {5E2507A2-DA03-446F-9F65-7E133DF1276E}.dll!Detail::DelegateCreator<void (cdecl ShaderCompiler::)(void )>::MakeFrameProxy::l2::::operator()(void frame, void ) Line 79 C++ GRS.Backends.DX12.Layer {5E2507A2-DA03-446F-9F65-7E133DF1276E}.dll!_Closure_wrapper_095bea0a_1::(void __p1, void p2) Line 76 C++ GRS.Backends.DX12.Layer {5E2507A2-DA03-446F-9F65-7E133DF1276E}.dll!Delegate<void cdecl(void )>::Invoke(void ) Line 46 C++ GRS.Backends.DX12.Layer {5E2507A2-DA03-446F-9F65-7E133DF1276E}.dll!DispatcherWorker::ThreadEntry() Line 66 C++

It hits the following assert: ASSERT(table.dxilModule, "PSV not supported for native DXBC");

I presume that GPU Reshape does not support this game based on what I see from the assert. Release mode GPU Reshape simply crashes the game with an access violation error. Rather than crashing the game, I would prefer to get an error/warning message in my GPU Reshape UI and let the game continue to run.

Hi Lou,

This is fixed in mainline, currently native DXBC modules are reported as "failed", but I'll see about hooking it up to something better.

There is a path which converts DXBC to DXIL using the MS provided utilities, but it's a little shaky at the moment, not production ready.

Closing this as the crash itself was fixed.
