Russ Cox	a392cf4fd3	runtime: fix test ... Was supposed to be in the nm CL. TBR=r CC=golang-dev https://golang.org/cl/42870043	2013-12-16 12:59:30 -05:00
Russ Cox	439f9397fc	runtime: avoid inconsistent goroutine state in profiler ... Because profiling signals can arrive at any time, we must handle the case where a profiling signal arrives halfway through a goroutine switch. Luckily, although there is much to think through, very little needs to change. Fixes #6000. Fixes #6015. R=golang-dev, dvyukov CC=golang-dev https://golang.org/cl/13421048	2013-09-13 14:19:23 -04:00

Russ Cox	f91cc3bdbb	gc: optimize interface ==, != ... If the values being compared have different concrete types, then they're clearly unequal without needing to invoke the actual interface compare routine. This speeds tests for specific values, like if err == io.EOF, by about 3x. benchmark old ns/op new ns/op delta BenchmarkIfaceCmp100 843 287 -65.95% BenchmarkIfaceCmpNil100 184 182 -1.09% Fixes #2591.
