I believe the benchmarks that get slower are under register pressure, and not making the call unconditionally makes the pressure worse, and the register allocator doesn't do a great job. But part of the point of this sequence is to get the write barriers out of the way so I can work on the register allocator, so that's okay. name old new delta BenchmarkBinaryTree17 17.9s × (1.00,1.01) 18.0s × (0.99,1.01) ~ BenchmarkFannkuch11 4.43s × (1.00,1.00) 4.43s × (1.00,1.00) ~ BenchmarkFmtFprintfEmpty 110ns × (1.00,1.06) 114ns × (0.95,1.05) ~ BenchmarkFmtFprintfString 487ns × (0.99,1.00) 468ns × (0.99,1.01) -4.00% BenchmarkFmtFprintfInt 450ns × (0.99,1.00) 433ns × (1.00,1.01) -3.88% BenchmarkFmtFprintfIntInt 762ns × (1.00,1.00) 748ns × (0.99,1.01) -1.84% BenchmarkFmtFprintfPrefixedInt 584ns × (0.99,1.01) 547ns × (0.99,1.01) -6.26% BenchmarkFmtFprintfFloat 738ns × (1.00,1.00) 756ns × (1.00,1.01) +2.37% BenchmarkFmtManyArgs 2.80µs × (1.00,1.01) 2.79µs × (1.00,1.01) ~ BenchmarkGobDecode 39.0ms × (0.99,1.00) 39.6ms × (0.99,1.00) +1.54% BenchmarkGobEncode 37.8ms × (0.98,1.01) 37.6ms × (1.00,1.01) ~ BenchmarkGzip 661ms × (0.99,1.01) 663ms × (0.99,1.02) ~ BenchmarkGunzip 142ms × (1.00,1.00) 142ms × (1.00,1.00) ~ BenchmarkHTTPClientServer 132µs × (0.99,1.01) 132µs × (0.99,1.01) ~ BenchmarkJSONEncode 56.3ms × (0.99,1.01) 56.2ms × (0.99,1.01) ~ BenchmarkJSONDecode 138ms × (0.99,1.01) 138ms × (1.00,1.00) ~ BenchmarkMandelbrot200 6.01ms × (1.00,1.00) 6.03ms × (1.00,1.01) +0.23% BenchmarkGoParse 10.2ms × (0.87,1.05) 9.8ms × (0.93,1.10) ~ BenchmarkRegexpMatchEasy0_32 208ns × (1.00,1.00) 207ns × (1.00,1.00) ~ BenchmarkRegexpMatchEasy0_1K 588ns × (1.00,1.00) 581ns × (1.00,1.01) -1.27% BenchmarkRegexpMatchEasy1_32 182ns × (0.99,1.01) 185ns × (0.99,1.01) +1.65% BenchmarkRegexpMatchEasy1_1K 986ns × (1.00,1.01) 975ns × (1.00,1.01) -1.17% BenchmarkRegexpMatchMedium_32 323ns × (1.00,1.01) 328ns × (0.99,1.00) +1.55% BenchmarkRegexpMatchMedium_1K 89.9µs × (1.00,1.00) 88.6µs × (1.00,1.01) -1.38% BenchmarkRegexpMatchHard_32 4.72µs × (0.95,1.01) 4.69µs × (0.95,1.03) ~ BenchmarkRegexpMatchHard_1K 133µs × (1.00,1.01) 133µs × (1.00,1.01) ~ BenchmarkRevcomp 900ms × (1.00,1.05) 902ms × (0.99,1.05) ~ BenchmarkTemplate 168ms × (0.99,1.01) 174ms × (0.99,1.01) +3.30% BenchmarkTimeParse 637ns × (1.00,1.00) 639ns × (1.00,1.00) +0.31% BenchmarkTimeFormat 738ns × (1.00,1.00) 736ns × (1.00,1.01) ~ Change-Id: I03ce152852edec404538f6c20eb650fac82e2aa2 Reviewed-on: https://go-review.googlesource.com/9224Reviewed-by:
