I just checked again, and "target symbols add" depends on having a real
SymbolVendor implementation. So unfortunately we still need a temporary
So far we're left with:
1) look in the current directory
2) look in the same directory as the .dmp file (we can't use the .exe/.dll
locations since we don't have them in this case)
I know we had a bit of back and forth about this. After revisiting the code
(and for what is worth taking Visual Studio and windbg behavior in
consideration), I still think that the current directory is the best
choice. It's consistent with what LLDB already does for DWARF, so it's not
adding another magic lookup.
