This is a meta bug to track all our problems with debug info in asan.
These problems together form one of our major issues.
- Stability: wrong debug info hurts code with exceptions.
http://llvm.org/bugs/show_bug.cgi?id=11468
- Debug info quality (can't use gdb properly):
http://llvm.org/bugs/show_bug.cgi?id=11818
likely caused by stack realignment and related to the one above.
- Huge size of debug info. http://llvm.org/bugs/show_bug.cgi?id=7554
I am not sure if the problem is well understood.
LLVM's debug info on linux is much bigger than with gcc. asan makes it worse.
- gmlt (minimal line tables). Consider adding a flag similar to gcc's -gmlt
(http://old.nabble.com/-patch--Add-new--gmlt-option-for-min.-debug-info-with-lin
e-tables-(issue4440072)-td31482851.html).
This will allow to have fully symbolized stacks traces with smaller debug info.
One option it to implement this as an LLVM pass which will strip all irrelevant
metadata.
