Things that still need to be done: -*- Text -*-
o - Performance
All performance could be tuned, but one area that could be looked
at especially is performance with flags, particularly
--detect-odr-violations and --compress-debug-sections.
o - Threads
Why is the usertime when we run with threads the same (or almost
the same) as when we run without? Is it because threads spend most
of their time waiting on the same resources? On each other?
o - ODR false positives
ODR false positives can happen when we optimize, since code in .h
files may be optimized in different ways in different compilation
units. It's possible we could fix this for real by looking at the
full debug info and using DW_TAG_inlined_subroutine in a clever way
to correct for inlining. But that would be very expensive, I
think. The easier solution is to recommend people only do
ODR-detection with -g0.
o - Better testing
