Keith Randall	1e0b378905	runtime: use right mask to extract type kind ... Cleanup from recent malloc changes. LGTM=dvyukov R=dvyukov CC=golang-codereviews https://golang.org/cl/120960043	2014-07-31 09:32:09 -07:00
Keith Randall	4aa50434e1	runtime: rewrite malloc in Go. ... This change introduces gomallocgc, a Go clone of mallocgc. Only a few uses have been moved over, so there are still lots of uses from C. Many of these C uses will be moved over to Go (e.g. in slice.goc), but probably not all. What should remain of C's mallocgc is an open question.

Keith Randall	0c6b55e76b	runtime: convert map implementation to Go. ... It's a bit slower, but not painfully so. There is still room for improvement (saving space so we can use nosplit, and removing the requirement for hash/eq stubs). benchmark old ns/op new ns/op delta BenchmarkMegMap 23.5 24.2 +2.98% BenchmarkMegOneMap 14.9 15.7 +5.37% BenchmarkMegEqMap 71668 72234 +0.79% BenchmarkMegEmptyMap 4.05 4.93 +21.73% BenchmarkSmallStrMap 21.9 22.5 +2.74% BenchmarkMapStringKeysEight_16 23.1 26.3 +13.85% BenchmarkMapStringKeysEight_32 21.9 25.0 +14.16% BenchmarkMapStringKeysEight_64 21.9 25.1 +14.61% BenchmarkMapStringKeysEight_1M 21.9 25.0 +14.16% BenchmarkIntMap 21.8 12.5 -42.66% BenchmarkRepeatedLookupStrMapKey32 39.3 30.2 -23.16% BenchmarkRepeatedLookupStrMapKey1M 322353 322675 +0.10% BenchmarkNewEmptyMap 129 136 +5.43% BenchmarkMapIter 137 107 -21.90% BenchmarkMapIterEmpty 7.14 8.71 +21.99% BenchmarkSameLengthMap 5.24 6.82 +30.15% BenchmarkBigKeyMap 34.5 35.3 +2.32% BenchmarkBigValMap 36.1 36.1 +0.00% BenchmarkSmallKeyMap 26.9 26.7 -0.74% LGTM=rsc R=golang-codereviews, dave, dvyukov, rsc, gobot, khr CC=golang-codereviews https://golang.org/cl/99380043	2014-07-16 14:16:19 -07:00

Dmitriy Vyukov	51e89f59b2	runtime: add RaceRead/RaceWrite functions ... It allows to catch e.g. a data race between atomic write and non-atomic write, or Mutex.Lock() and mutex overwrite (e.g. mu = Mutex{}). R=golang-dev, rsc CC=golang-dev https://golang.org/cl/6817103	2012-11-14 16:51:23 +04:00
