// The bitmap in the name tells which words being copied are pointers.
runtime: change unused argument in fat write barriers from pointer to scalar The argument is unused, only present for alignment of the following argument. The compiler today always passes a zero but I'd rather not write anything there during the call sequence, so mark it as a scalar so the garbage collector won't look at it. As expected, no significant performance change. name old new delta BenchmarkBinaryTree17 17.9s × (0.99,1.00) 17.9s × (0.99,1.01) ~ BenchmarkFannkuch11 4.35s × (1.00,1.00) 4.35s × (1.00,1.00) ~ BenchmarkFmtFprintfEmpty 120ns × (0.94,1.05) 120ns × (0.93,1.06) ~ BenchmarkFmtFprintfString 477ns × (1.00,1.00) 479ns × (0.99,1.00) ~ BenchmarkFmtFprintfInt 450ns × (0.99,1.01) 452ns × (0.99,1.02) ~ BenchmarkFmtFprintfIntInt 765ns × (0.99,1.01) 766ns × (0.99,1.01) ~ BenchmarkFmtFprintfPrefixedInt 569ns × (0.99,1.01) 576ns × (0.98,1.01) ~ BenchmarkFmtFprintfFloat 728ns × (1.00,1.00) 730ns × (1.00,1.01) ~ BenchmarkFmtManyArgs 2.82µs × (0.99,1.01) 2.84µs × (0.99,1.00) ~ BenchmarkGobDecode 39.1ms × (0.99,1.01) 39.3ms × (0.98,1.01) ~ BenchmarkGobEncode 39.4ms × (0.99,1.01) 39.5ms × (0.99,1.01) ~ BenchmarkGzip 661ms × (0.99,1.01) 663ms × (1.00,1.01) ~ BenchmarkGunzip 143ms × (1.00,1.00) 143ms × (1.00,1.00) ~ BenchmarkHTTPClientServer 133µs × (0.99,1.01) 132µs × (0.99,1.01) ~ BenchmarkJSONEncode 57.3ms × (0.99,1.04) 57.4ms × (0.99,1.01) ~ BenchmarkJSONDecode 139ms × (0.99,1.00) 139ms × (0.99,1.00) ~ BenchmarkMandelbrot200 6.02ms × (1.00,1.00) 6.03ms × (1.00,1.00) ~ BenchmarkGoParse 9.72ms × (0.92,1.11) 10.31ms × (0.89,1.14) ~ BenchmarkRegexpMatchEasy0_32 209ns × (1.00,1.01) 209ns × (1.00,1.00) ~ BenchmarkRegexpMatchEasy0_1K 592ns × (0.99,1.00) 591ns × (0.99,1.00) ~ BenchmarkRegexpMatchEasy1_32 183ns × (0.98,1.01) 184ns × (0.99,1.02) ~ BenchmarkRegexpMatchEasy1_1K 1.01µs × (1.00,1.01) 1.01µs × (1.00,1.00) ~ BenchmarkRegexpMatchMedium_32 330ns × (1.00,1.00) 330ns × (1.00,1.00) ~ BenchmarkRegexpMatchMedium_1K 92.4µs × (1.00,1.00) 92.6µs × (1.00,1.00) ~ BenchmarkRegexpMatchHard_32 4.77µs × (0.95,1.01) 4.80µs × (0.95,1.00) ~ BenchmarkRegexpMatchHard_1K 136µs × (1.00,1.00) 136µs × (1.00,1.00) ~ BenchmarkRevcomp 906ms × (0.99,1.05) 900ms × (0.99,1.04) ~ BenchmarkTemplate 171ms × (0.99,1.01) 172ms × (1.00,1.00) ~ BenchmarkTimeParse 638ns × (1.00,1.00) 637ns × (1.00,1.00) ~ BenchmarkTimeFormat 745ns × (0.99,1.02) 744ns × (1.00,1.01) ~ Change-Id: I0aeac5dc7adfd75e2223e3aabfedc7818d339f9b Reviewed-on: https://go-review.googlesource.com/9320 Reviewed-by: Austin Clements <austin@google.com>
