+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?
+ Something else?
+
+ 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
