Description Vadim Girlin 2013-07-14 00:27:17 UTC
I have asserts in the middle of shader dump in llvm backend with 32-bit Team Fortress 2 and Lightsmark, R600_DEBUG=ps,vs. Here is message with Lightsmark:

ALU_CLAUSE 8; dbg:backend: DebugLoc.cpp:27: llvm::MDNode* llvm::DebugLoc::getScope(const llvm::LLVMContext&) const: Assertion `unsigned(ScopeIdx) <= Ctx.pImpl->ScopeRecords.size() && "Invalid ScopeIdx!"' failed.

TF2 message:

ALU_CLAUSE 32; dbg:hl2_linux: DebugLoc.cpp:33: llvm::MDNode* llvm::DebugLoc::getScope(const llvm::LLVMContext&) const: Assertion `unsigned(-ScopeIdx) <= Ctx.pImpl->ScopeInlinedAtRecords.size() && "Invalid ScopeIdx"' failed.

It seems in both cases it happens on ALU clause start in the dump.
So far I can't reproduce this issue with 64-bit Lightsmark/mesa/llvm.
