Summary: [r600 llvm backend] Assert with 32-bit lightsmark, TF2
when shader dump is enabled
Severity: normal
Classification: Unclassified
OS: All
Reporter: ptpzz at yandex.ru
Hardware: Other
Status: NEW
Version: git
Component: Drivers/Gallium/r600
Product: Mesa
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.
