Bug ID: 31437
Summary: Assertion with LTO and debug info when mixing -g and
-gmlt
Product: libraries
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: Common Code Generator Code
Assignee: unassignedb...@nondot.org
Reporter: paul_robin...@playstation.sony.com
CC: llvm-bugs@lists.llvm.org
Classification: Unclassified
Created attachment 17776
--> https://llvm.org/bugs/attachment.cgi?id=17776&action=edit
two .cpp files and a .sh script to reproduce
If we compile one module with -g and another with -gmlt this can trigger
a crash in DwarfDebug.
llc:
/home/probinson/projects/llvm-org/trunk/llvm/lib/CodeGen/AsmPrinter/DwarfDebug.cpp:1216:
virtual void llvm::DwarfDebug::endFunction(const llvm::MachineFunction*):
Assertion `DbgValues.empty()' failed.
It looks like this assert was added in r218129.
Also another one next to it, for AbstractVariables.empty().
We should be able to conjure up repro for that one too if you want.
