1 Things that still need to be done: -*- Text -*- 2 3 o - Performance 4 5 All performance could be tuned, but one area that could be looked 6 at especially is performance with flags, particularly 7 --detect-odr-violations and --compress-debug-sections. 8 9 o - Threads 10 11 Why is the usertime when we run with threads the same (or almost 12 the same) as when we run without? Is it because threads spend most 13 of their time waiting on the same resources? On each other? 14 Something else? 15 16 o - ODR false positives 17 18 ODR false positives can happen when we optimize, since code in .h 19 files may be optimized in different ways in different compilation 20 units. It's possible we could fix this for real by looking at the 21 full debug info and using DW_TAG_inlined_subroutine in a clever way 22 to correct for inlining. But that would be very expensive, I 23 think. The easier solution is to recommend people only do 24 ODR-detection with -g0. 25 26 o - Better testing 27
