cmd/compile, runtime: specialize convT2x, don't alloc for zero vals
Prior to this CL, all runtime conversions from a concrete value to an interface went through one of two runtime calls: convT2E or convT2I. However, in practice, basic types are very common. Specializing convT2x for those basic types allows for a more efficient implementation for those types. For basic scalars and strings, allocation and copying can use the same methods as normal code. For pointer-free types, allocation can occur without zeroing, and copying can take place without GC calls. For slices, copying is cheaper and simpler. This CL adds twelve runtime routines: convT2E16, convT2I16 convT2E32, convT2I32 convT2E64, convT2I64 convT2Estring, convT2Istring convT2Eslice, convT2Islice convT2Enoptr, convT2Inoptr While compiling make.bash, 93% of all convT2x calls are now to one of these specialized convT2x call. Within specialized convT2x routines, it is cheap to check for a zero value, in a way that it is not in general. When we detect a zero value there, we return a pointer to zeroVal, rather than allocating. name old time/op new time/op delta ConvT2Ezero/zero/16-8 17.9ns ± 2% 3.0ns ± 3% -83.20% (p=0.000 n=56+56) ConvT2Ezero/zero/32-8 17.8ns ± 2% 3.0ns ± 3% -83.15% (p=0.000 n=59+60) ConvT2Ezero/zero/64-8 20.1ns ± 1% 3.0ns ± 2% -84.98% (p=0.000 n=57+57) ConvT2Ezero/zero/str-8 32.6ns ± 1% 3.0ns ± 4% -90.70% (p=0.000 n=59+60) ConvT2Ezero/zero/slice-8 36.7ns ± 2% 3.0ns ± 2% -91.78% (p=0.000 n=59+59) ConvT2Ezero/zero/big-8 91.9ns ± 2% 85.9ns ± 2% -6.52% (p=0.000 n=57+57) ConvT2Ezero/nonzero/16-8 17.7ns ± 2% 12.7ns ± 3% -28.38% (p=0.000 n=55+60) ConvT2Ezero/nonzero/32-8 17.8ns ± 1% 12.7ns ± 1% -28.44% (p=0.000 n=54+57) ConvT2Ezero/nonzero/64-8 20.0ns ± 1% 15.0ns ± 1% -24.90% (p=0.000 n=56+58) ConvT2Ezero/nonzero/str-8 32.6ns ± 1% 25.7ns ± 1% -21.17% (p=0.000 n=58+55) ConvT2Ezero/nonzero/slice-8 36.8ns ± 2% 30.4ns ± 1% -17.32% (p=0.000 n=60+52) ConvT2Ezero/nonzero/big-8 92.1ns ± 2% 85.9ns ± 2% -6.70% (p=0.000 n=57+59) Benchmarks on a real program (the compiler): name old time/op new time/op delta Template 227ms ± 5% 221ms ± 2% -2.48% (p=0.000 n=30+26) Unicode 102ms ± 5% 100ms ± 3% -1.30% (p=0.009 n=30+26) GoTypes 656ms ± 5% 659ms ± 4% ~ (p=0.208 n=30+30) Compiler 2.82s ± 2% 2.82s ± 1% ~ (p=0.614 n=29+27) Flate 128ms ± 2% 128ms ± 5% ~ (p=0.783 n=27+28) GoParser 158ms ± 3% 158ms ± 3% ~ (p=0.261 n=28+30) Reflect 408ms ± 7% 401ms ± 3% ~ (p=0.075 n=30+30) Tar 123ms ± 6% 121ms ± 8% ~ (p=0.287 n=29+30) XML 220ms ± 2% 220ms ± 4% ~ (p=0.805 n=29+29) name old user-ns/op new user-ns/op delta Template 281user-ms ± 4% 279user-ms ± 3% -0.87% (p=0.044 n=28+28) Unicode 142user-ms ± 4% 141user-ms ± 3% -1.04% (p=0.015 n=30+27) GoTypes 884user-ms ± 3% 886user-ms ± 2% ~ (p=0.532 n=30+30) Compiler 3.94user-s ± 3% 3.92user-s ± 1% ~ (p=0.185 n=30+28) Flate 165user-ms ± 2% 165user-ms ± 4% ~ (p=0.780 n=27+29) GoParser 209user-ms ± 2% 208user-ms ± 3% ~ (p=0.453 n=28+30) Reflect 533user-ms ± 6% 526user-ms ± 3% ~ (p=0.057 n=30+30) Tar 156user-ms ± 6% 154user-ms ± 6% ~ (p=0.133 n=29+30) XML 288user-ms ± 4% 288user-ms ± 4% ~ (p=0.633 n=30+30) name old alloc/op new alloc/op delta Template 41.0MB ± 0% 40.9MB ± 0% -0.11% (p=0.000 n=29+29) Unicode 32.6MB ± 0% 32.6MB ± 0% ~ (p=0.572 n=29+30) GoTypes 122MB ± 0% 122MB ± 0% -0.10% (p=0.000 n=30+30) Compiler 482MB ± 0% 481MB ± 0% -0.07% (p=0.000 n=30+29) Flate 26.6MB ± 0% 26.6MB ± 0% ~ (p=0.096 n=30+30) GoParser 32.7MB ± 0% 32.6MB ± 0% -0.06% (p=0.011 n=28+28) Reflect 84.2MB ± 0% 84.1MB ± 0% -0.17% (p=0.000 n=29+30) Tar 27.7MB ± 0% 27.7MB ± 0% -0.05% (p=0.032 n=27+28) XML 44.7MB ± 0% 44.7MB ± 0% ~ (p=0.131 n=28+30) name old allocs/op new allocs/op delta Template 373k ± 1% 370k ± 1% -0.76% (p=0.000 n=30+30) Unicode 325k ± 1% 325k ± 1% ~ (p=0.383 n=29+30) GoTypes 1.16M ± 0% 1.15M ± 0% -0.75% (p=0.000 n=29+30) Compiler 4.15M ± 0% 4.13M ± 0% -0.59% (p=0.000 n=30+29) Flate 238k ± 1% 237k ± 1% -0.62% (p=0.000 n=30+30) GoParser 304k ± 1% 302k ± 1% -0.64% (p=0.000 n=30+28) Reflect 1.00M ± 0% 0.99M ± 0% -1.10% (p=0.000 n=29+30) Tar 245k ± 1% 244k ± 1% -0.59% (p=0.000 n=27+29) XML 391k ± 1% 389k ± 1% -0.59% (p=0.000 n=29+30) Change-Id: Id7f456d690567c2b0a96b0d6d64de8784b6e305f Reviewed-on: https://go-review.googlesource.com/36476 Run-TryBot: Josh Bleecher Snyder <josharian@gmail.com> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by: Keith Randall <khr@golang.org>
