<div>
<pre>If i have a virtual in a subclass that hides a non-virtual in a base-class,
LLDB calls the non-virtual.
Example from LLVM:
class Value {
..
/// \brief Support for debugging, callable in GDB: V->dump()
void dump() const;
}
<somewhere else>
class MemoryAccess: public Value {
virtual void dump() const;
}
(lldb) p Dominator->MemoryAccess::dump()
1 = MemoryDef(liveOnEntry)
(this is the correct dump)
(lldb) p Dominator->dump()
While deleting: void %
Use still stuck around after Def is destroyed:Unknown value to print out!
UNREACHABLE executed at ../lib/IR/AsmWriter.cpp:3437!
error: Execution was interrupted, reason: signal SIGABRT.
The process has been returned to the state before expression evaluation.
This is calling Value::dump().
What dump is called certainly depends on the pointer type.
If the pointer type here was Value*, i would expect this behavior.
However, it is "const MemoryAccess *Dominator", so it should be calling the
virtual dump here.
(and for anyone curious, fixing llvm ... would be hard :P)
gdb calls the correct dump here :)</pre>
