Bug ID: 26833
Summary: [CodeView] assertion after optimizing code with debug
info
Product: new-bugs
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: normal
Priority: P
Component: new bugs
Assignee: unassignedb...@nondot.org
Reporter: r.sagita...@gmx.de
CC: llvm-bugs@lists.llvm.org
Classification: Unclassified
The attached IR compiles fine with "llc", but triggers an assertion if
optimized before with "opt -O2":
Assertion failed: cast<DISubprogram>(Scope)->describes(MF->getFunction()), file
C:\s\d\ldc\llvm\lib\CodeGen\LexicalScopes.cpp, line 160
Strangely, it doesn't assert with "llc -O2". The same compiles without debug
info.
