Dmitry Vyukov b3be360f16 cmd/gc: allocate non-escaping maps on stack ... Extend escape analysis to make(map[k]v). If it does not escape, allocate temp buffer for hmap and one bucket on stack. There are 75 cases of non-escaping maps in std lib. benchmark old allocs new allocs delta BenchmarkConcurrentStmtQuery 16161 15161 -6.19% BenchmarkConcurrentTxQuery 17658 16658 -5.66% BenchmarkConcurrentTxStmtQuery 16157 15156 -6.20% BenchmarkConcurrentRandom 13637 13114 -3.84% BenchmarkManyConcurrentQueries 22 20 -9.09% BenchmarkDecodeComplex128Slice 250 188 -24.80% BenchmarkDecodeFloat64Slice 250 188 -24.80% BenchmarkDecodeInt32Slice 250 188 -24.80% BenchmarkDecodeStringSlice 2250 2188 -2.76% BenchmarkNewEmptyMap 1 0 -100.00% BenchmarkNewSmallMap 2 0 -100.00% benchmark old ns/op new ns/op delta BenchmarkNewEmptyMap 124 55.7 -55.08% BenchmarkNewSmallMap 317 148 -53.31% benchmark old allocs new allocs delta BenchmarkNewEmptyMap 1 0 -100.00% BenchmarkNewSmallMap 2 0 -100.00% benchmark old bytes new bytes delta BenchmarkNewEmptyMap 48 0 -100.00% BenchmarkNewSmallMap 192 0 -100.00% Fixes #5449 Change-Id: I24fa66f949d2f138885d9e66a0d160240dc9e8fa Reviewed-on: https://go-review.googlesource.com/3508 Reviewed-by: Keith Randall <khr@golang.org> Run-TryBot: Dmitry Vyukov <dvyukov@google.com>		2015-02-12 09:53:52 +00:00
