Hi, I've noticed that the code produced by Barrier Breaker's toolchain sometimes has significantly worse performance that that built by Attitude Adjustment.
I can see this extremely with the VPN tool "fastd" developed and maintained by me: On the same Barrier Breaker system, a binary built by the default Barrier Breaker toolchain (GCC 4.8-linaro) gets about 35% less throughput than one built with Attitude Adjustment (GCC 4.6-linaro). With the 4.6-linaro toolchain of Barrier Breaker, I still get 20% worse performance than with the 4.6-linaro of Attitude Adjustment. Do you have any suggestions what I can do to solve or analyze the issue? Any compiler flags I should try fiddling with? Optimizing with -Os vs. -O3 doesn't seem to make a difference. Thanks, Matthias
