I'm seeing some ARM optimisation weaknesses (with gcc 4.3.2, so perhaps I'm behind the times) and I was wondering if anyone on this list knows a good place to report and discuss this? The sort of things I'm seeing are: poor register allocation resulting in unecessary register spillage, not taking __builtin_expect seriously enough, and unnecessarily preloading a constant into a register so spilling yet another register! It's just one bit of tight code where I was paying particular attention to timing. Anyhow, probably a bit off topic, but I'm sure some folk here know what I'm talking about. -- For unsubscribe information see http://sourceware.org/lists.html#faq
