This allows the one-pass executions to have their own pool of (much smaller) allocated structures. A step toward eliminating the per-Regexp machine cache. Not much effect on benchmarks, since there are no optimizations here, and pools are a tiny bit slower than a locked data structure for single-threaded code. name old time/op new time/op delta Find-12 254ns ± 0% 252ns ± 0% -0.94% (p=0.000 n=9+10) FindAllNoMatches-12 135ns ± 0% 134ns ± 1% -0.49% (p=0.002 n=9+9) FindString-12 247ns ± 0% 246ns ± 0% -0.24% (p=0.003 n=8+10) FindSubmatch-12 334ns ± 0% 333ns ± 2% ~ (p=0.283 n=10+10) FindStringSubmatch-12 321ns ± 0% 320ns ± 0% -0.51% (p=0.000 n=9+10) Literal-12 92.2ns ± 0% 91.1ns ± 0% -1.25% (p=0.000 n=9+10) NotLiteral-12 1.47µs ± 0% 1.45µs ± 0% -0.99% (p=0.000 n=9+10) MatchClass-12 2.17µs ± 0% 2.19µs ± 0% +0.84% (p=0.000 n=7+9) MatchClass_InRange-12 2.13µs ± 0% 2.09µs ± 0% -1.70% (p=0.000 n=10+10) ReplaceAll-12 1.39µs ± 0% 1.39µs ± 0% +0.51% (p=0.000 n=10+10) AnchoredLiteralShortNonMatch-12 83.2ns ± 0% 82.4ns ± 0% -0.96% (p=0.000 n=8+8) AnchoredLiteralLongNonMatch-12 105ns ± 0% 106ns ± 1% ~ (p=0.087 n=10+10) AnchoredShortMatch-12 131ns ± 0% 130ns ± 0% -0.76% (p=0.000 n=10+9) AnchoredLongMatch-12 267ns ± 0% 272ns ± 0% +2.01% (p=0.000 n=10+8) OnePassShortA-12 611ns ± 0% 615ns ± 0% +0.61% (p=0.000 n=9+10) NotOnePassShortA-12 552ns ± 0% 549ns ± 0% -0.46% (p=0.000 n=8+9) OnePassShortB-12 491ns ± 0% 494ns ± 0% +0.61% (p=0.000 n=8+8) NotOnePassShortB-12 412ns ± 0% 412ns ± 1% ~ (p=0.151 n=9+10) OnePassLongPrefix-12 112ns ± 0% 108ns ± 0% -3.57% (p=0.000 n=10+10) OnePassLongNotPrefix-12 410ns ± 0% 402ns ± 0% -1.95% (p=0.000 n=9+8) MatchParallelShared-12 38.8ns ± 1% 38.6ns ± 2% ~ (p=0.536 n=10+9) MatchParallelCopied-12 39.2ns ± 3% 39.4ns ± 7% ~ (p=0.986 n=10+10) QuoteMetaAll-12 94.6ns ± 0% 94.9ns ± 0% +0.29% (p=0.001 n=8+9) QuoteMetaNone-12 52.7ns ± 0% 52.7ns ± 0% ~ (all equal) Match/Easy0/32-12 72.9ns ± 0% 72.1ns ± 0% -1.07% (p=0.000 n=9+9) Match/Easy0/1K-12 298ns ± 0% 298ns ± 0% ~ (p=0.140 n=6+8) Match/Easy0/32K-12 4.60µs ± 2% 4.64µs ± 1% ~ (p=0.171 n=10+10) Match/Easy0/1M-12 235µs ± 0% 234µs ± 0% -0.14% (p=0.004 n=10+10) Match/Easy0/32M-12 7.96ms ± 0% 7.95ms ± 0% -0.12% (p=0.043 n=10+9) Match/Easy0i/32-12 1.09µs ± 0% 1.10µs ± 0% +0.15% (p=0.000 n=8+9) Match/Easy0i/1K-12 31.7µs ± 0% 31.8µs ± 1% ~ (p=0.905 n=9+10) Match/Easy0i/32K-12 1.61ms ± 0% 1.62ms ± 1% +1.12% (p=0.000 n=9+10) Match/Easy0i/1M-12 51.4ms ± 0% 51.8ms ± 0% +0.85% (p=0.000 n=8+8) Match/Easy0i/32M-12 1.65s ± 1% 1.65s ± 0% ~ (p=0.113 n=9+9) Match/Easy1/32-12 67.9ns ± 0% 67.7ns ± 1% ~ (p=0.232 n=8+10) Match/Easy1/1K-12 884ns ± 0% 873ns ± 0% -1.29% (p=0.000 n=9+10) Match/Easy1/32K-12 39.2µs ± 0% 39.4µs ± 0% +0.50% (p=0.000 n=9+10) Match/Easy1/1M-12 1.39ms ± 0% 1.39ms ± 0% +0.29% (p=0.000 n=9+10) Match/Easy1/32M-12 44.2ms ± 1% 44.3ms ± 0% +0.21% (p=0.029 n=10+10) Match/Medium/32-12 1.05µs ± 0% 1.04µs ± 0% -0.27% (p=0.001 n=8+9) Match/Medium/1K-12 31.3µs ± 0% 31.4µs ± 0% +0.39% (p=0.000 n=9+8) Match/Medium/32K-12 1.45ms ± 0% 1.45ms ± 0% +0.33% (p=0.000 n=8+9) Match/Medium/1M-12 46.2ms ± 0% 46.4ms ± 0% +0.35% (p=0.000 n=9+8) Match/Medium/32M-12 1.48s ± 0% 1.49s ± 1% +0.70% (p=0.000 n=8+10) Match/Hard/32-12 1.49µs ± 0% 1.48µs ± 0% -0.43% (p=0.000 n=10+9) Match/Hard/1K-12 45.1µs ± 1% 45.0µs ± 1% ~ (p=0.393 n=10+10) Match/Hard/32K-12 2.18ms ± 1% 2.24ms ± 0% +2.71% (p=0.000 n=9+8) Match/Hard/1M-12 69.7ms ± 1% 71.6ms ± 0% +2.76% (p=0.000 n=9+7) Match/Hard/32M-12 2.23s ± 1% 2.29s ± 0% +2.65% (p=0.000 n=9+9) Match/Hard1/32-12 7.89µs ± 0% 7.89µs ± 0% ~ (p=0.286 n=9+9) Match/Hard1/1K-12 244µs ± 0% 244µs ± 0% ~ (p=0.905 n=9+10) Match/Hard1/32K-12 10.3ms ± 0% 10.3ms ± 0% ~ (p=0.796 n=10+10) Match/Hard1/1M-12 331ms ± 0% 331ms ± 0% ~ (p=0.167 n=8+9) Match/Hard1/32M-12 10.6s ± 0% 10.6s ± 0% ~ (p=0.315 n=8+10) Match_onepass_regex/32-12 812ns ± 0% 830ns ± 0% +2.19% (p=0.000 n=10+9) Match_onepass_regex/1K-12 28.5µs ± 0% 28.7µs ± 1% +0.97% (p=0.000 n=10+9) Match_onepass_regex/32K-12 936µs ± 0% 949µs ± 0% +1.43% (p=0.000 n=10+8) Match_onepass_regex/1M-12 30.2ms ± 0% 30.4ms ± 0% +0.62% (p=0.000 n=10+8) Match_onepass_regex/32M-12 970ms ± 0% 973ms ± 0% +0.35% (p=0.000 n=10+9) CompileOnepass-12 4.63µs ± 1% 4.64µs ± 0% ~ (p=0.060 n=10+10) [Geo mean] 23.3µs 23.3µs +0.12% https://perf.golang.org/search?q=upload:20181004.2 Change-Id: Iff9e9f9d4a4698162126a2f300e8ed1b1a39361e Reviewed-on: https://go-review.googlesource.com/c/139780 Run-TryBot: Russ Cox <rsc@golang.org> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by:

This allows the bit-state executions to have their own pool of allocated structures. A step toward eliminating the per-Regexp machine cache. Note especially the -92% on MatchParallelShared. This is real but not a complete story: the other execution engines still need to be de-shared, but the benchmark was only using bit-state. The tiny slowdowns in unrelated code are noise. name old time/op new time/op delta Find-12 264ns ± 3% 254ns ± 0% -3.86% (p=0.000 n=10+9) FindAllNoMatches-12 140ns ± 2% 135ns ± 0% -3.91% (p=0.000 n=10+9) FindString-12 256ns ± 0% 247ns ± 0% -3.52% (p=0.000 n=8+8) FindSubmatch-12 339ns ± 1% 334ns ± 0% -1.41% (p=0.000 n=9+10) FindStringSubmatch-12 322ns ± 0% 321ns ± 0% -0.21% (p=0.005 n=8+9) Literal-12 100ns ± 2% 92ns ± 0% -8.10% (p=0.000 n=10+9) NotLiteral-12 1.50µs ± 0% 1.47µs ± 0% -1.91% (p=0.000 n=8+9) MatchClass-12 2.18µs ± 0% 2.17µs ± 0% -0.20% (p=0.001 n=10+7) MatchClass_InRange-12 2.12µs ± 0% 2.13µs ± 0% +0.23% (p=0.000 n=10+10) ReplaceAll-12 1.41µs ± 0% 1.39µs ± 0% -1.30% (p=0.000 n=7+10) AnchoredLiteralShortNonMatch-12 89.8ns ± 0% 83.2ns ± 0% -7.35% (p=0.000 n=8+8) AnchoredLiteralLongNonMatch-12 105ns ± 3% 105ns ± 0% ~ (p=0.186 n=10+10) AnchoredShortMatch-12 141ns ± 0% 131ns ± 0% -7.09% (p=0.000 n=9+10) AnchoredLongMatch-12 276ns ± 4% 267ns ± 0% -3.23% (p=0.000 n=10+10) OnePassShortA-12 620ns ± 0% 611ns ± 0% -1.39% (p=0.000 n=10+9) NotOnePassShortA-12 575ns ± 3% 552ns ± 0% -3.97% (p=0.000 n=10+8) OnePassShortB-12 493ns ± 0% 491ns ± 0% -0.33% (p=0.000 n=8+8) NotOnePassShortB-12 423ns ± 0% 412ns ± 0% -2.60% (p=0.000 n=8+9) OnePassLongPrefix-12 112ns ± 0% 112ns ± 0% ~ (all equal) OnePassLongNotPrefix-12 405ns ± 0% 410ns ± 0% +1.23% (p=0.000 n=8+9) MatchParallelShared-12 501ns ± 1% 39ns ± 1% -92.27% (p=0.000 n=10+10) MatchParallelCopied-12 39.1ns ± 0% 39.2ns ± 3% ~ (p=0.785 n=6+10) QuoteMetaAll-12 94.6ns ± 0% 94.6ns ± 0% ~ (p=0.439 n=10+8) QuoteMetaNone-12 52.7ns ± 0% 52.7ns ± 0% ~ (all equal) Match/Easy0/32-12 79.1ns ± 0% 72.9ns ± 0% -7.85% (p=0.000 n=9+9) Match/Easy0/1K-12 307ns ± 1% 298ns ± 0% -2.99% (p=0.000 n=10+6) Match/Easy0/32K-12 4.65µs ± 2% 4.60µs ± 2% ~ (p=0.159 n=10+10) Match/Easy0/1M-12 234µs ± 0% 235µs ± 0% +0.17% (p=0.003 n=10+10) Match/Easy0/32M-12 7.98ms ± 1% 7.96ms ± 0% ~ (p=0.278 n=9+10) Match/Easy0i/32-12 1.13µs ± 1% 1.09µs ± 0% -3.24% (p=0.000 n=9+8) Match/Easy0i/1K-12 32.5µs ± 0% 31.7µs ± 0% -2.66% (p=0.000 n=9+9) Match/Easy0i/32K-12 1.59ms ± 0% 1.61ms ± 0% +0.75% (p=0.000 n=9+9) Match/Easy0i/1M-12 51.0ms ± 0% 51.4ms ± 0% +0.77% (p=0.000 n=10+8) Match/Easy0i/32M-12 1.63s ± 0% 1.65s ± 1% +1.24% (p=0.000 n=7+9) Match/Easy1/32-12 75.1ns ± 1% 67.9ns ± 0% -9.54% (p=0.000 n=8+8) Match/Easy1/1K-12 861ns ± 0% 884ns ± 0% +2.71% (p=0.000 n=8+9) Match/Easy1/32K-12 39.2µs ± 1% 39.2µs ± 0% ~ (p=0.090 n=10+9) Match/Easy1/1M-12 1.38ms ± 0% 1.39ms ± 0% ~ (p=0.095 n=10+9) Match/Easy1/32M-12 44.2ms ± 1% 44.2ms ± 1% ~ (p=0.218 n=10+10) Match/Medium/32-12 1.04µs ± 1% 1.05µs ± 0% +1.05% (p=0.000 n=9+8) Match/Medium/1K-12 31.3µs ± 0% 31.3µs ± 0% -0.14% (p=0.004 n=9+9) Match/Medium/32K-12 1.44ms ± 0% 1.45ms ± 0% +0.18% (p=0.001 n=8+8) Match/Medium/1M-12 46.1ms ± 0% 46.2ms ± 0% +0.13% (p=0.003 n=6+9) Match/Medium/32M-12 1.48s ± 0% 1.48s ± 0% +0.20% (p=0.002 n=9+8) Match/Hard/32-12 1.54µs ± 1% 1.49µs ± 0% -3.60% (p=0.000 n=9+10) Match/Hard/1K-12 46.4µs ± 1% 45.1µs ± 1% -2.78% (p=0.000 n=9+10) Match/Hard/32K-12 2.19ms ± 0% 2.18ms ± 1% -0.51% (p=0.006 n=8+9) Match/Hard/1M-12 70.1ms ± 0% 69.7ms ± 1% -0.52% (p=0.006 n=8+9) Match/Hard/32M-12 2.24s ± 0% 2.23s ± 1% -0.42% (p=0.046 n=8+9) Match/Hard1/32-12 8.17µs ± 1% 7.89µs ± 0% -3.42% (p=0.000 n=8+9) Match/Hard1/1K-12 254µs ± 2% 244µs ± 0% -3.91% (p=0.000 n=9+9) Match/Hard1/32K-12 9.58ms ± 1% 10.35ms ± 0% +8.00% (p=0.000 n=10+10) Match/Hard1/1M-12 306ms ± 1% 331ms ± 0% +8.27% (p=0.000 n=9+8) Match/Hard1/32M-12 9.79s ± 1% 10.60s ± 0% +8.29% (p=0.000 n=9+8) Match_onepass_regex/32-12 808ns ± 0% 812ns ± 0% +0.47% (p=0.000 n=8+10) Match_onepass_regex/1K-12 27.8µs ± 0% 28.5µs ± 0% +2.32% (p=0.000 n=8+10) Match_onepass_regex/32K-12 925µs ± 0% 936µs ± 0% +1.24% (p=0.000 n=9+10) Match_onepass_regex/1M-12 29.5ms ± 0% 30.2ms ± 0% +2.38% (p=0.000 n=10+10) Match_onepass_regex/32M-12 945ms ± 0% 970ms ± 0% +2.60% (p=0.000 n=9+10) CompileOnepass-12 4.67µs ± 0% 4.63µs ± 1% -0.84% (p=0.000 n=10+10) [Geo mean] 24.5µs 23.3µs -5.04% https://perf.golang.org/search?q=upload:20181004.1 Change-Id: Idbc2b76223718265657819ff38be2d9aba1c54b4 Reviewed-on: https://go-review.googlesource.com/c/139779 Run-TryBot: Russ Cox <rsc@golang.org> Reviewed-by:

When running benchmarks with profilers and trying to compare one run against another, it is very useful to be able to force each run to execute exactly the same number of iterations. Discussion on the proposal issue #24735 led to the decision to overload -benchtime, so that instead of saying -benchtime 10s to run a benchmark for 10 seconds, you say -benchtime 100x to run a benchmark 100 times. Fixes #24735. Change-Id: Id17c5bd18bd09987bb48ed12420d61ae9e200fd7 Reviewed-on: https://go-review.googlesource.com/c/139258 Run-TryBot: Russ Cox <rsc@golang.org> Reviewed-by:

The original need for the extra test case and issue was eliminated by https://golang.org/cl/116815 which introduced systematic cycle detection. Now that we correctly report the cycle, we can't say much about the invalid cast anyway (the type is invalid due to the cycle). A more sophisticated approach would be able to tell the size of a function type independent of the details of that type, but the type-checker is not set up for this kind of lazy type-checking. Fixes #23127.

Interface methods don't declare a receiver (it's implicit), but after type-checking the respective *types.Func objects are marked as methods by having a receiver. For interface methods, the receiver base type used to be the interface that declared the method in the first place, even if the method also appeared in other interfaces via embedding. A change in the computation of method sets for interfaces for Go1.10 changed that inadvertently, with the consequence that sometimes a method's receiver type ended up being an interface into which the method was embedded. The exact behavior also depended on file type-checking order, and because files are sometimes sorted by name, the behavior depended on file names. This didn't matter for type-checking (the typechecker doesn't need the receiver), but it matters for clients, and for printing of methods. This change fixes interface method receivers at the end of type-checking when we have all relevant information. Fixes #28005.

This benchmark - in contrast to all other benchmarks - was running the regexp match on 1-byte substrings of the input instead of the entire input. Worse, it was doing so by preallocating a slice of slices of every 1-byte substring. Needless to say, this does not accurately reflect what happens when the regexp matcher is given a large input.

I've linked the gophers discord. It's a well administered discord which already got many members, but it was never officially linked. For many people it's a quality proof if a discord is linked on the official page. I think there are much more people out there, who would prefer to use discord instead of slack or irc. The discord already got many users without even being promoted, so it's very likely there are many people who are interested in a discord, but they don't want to use unofficial discords. This discord shouldn't be seen as a competitor for the slack, it's a platform for those, who don't want to use slack.

It's long-desired but was blocked by #26835. That is now fixed, so it's easy. When -src is off, we behave as before. But with -src set, initialize the go/doc package to preserve the original AST and things flow very easily. With -src, since you're seeing inside the package source anyway it shows unexported fields and constants: you see the original source. But you still need -u to ask about them.

To save memory in godoc, this package routinely clears fields of the AST to avoid keeping data that godoc no longer needs. For other programs, such as cmd/doc, this behavior is unfortunate. Also, one should be able to tell any package like this, "don't change my data". Add a Mode bit, defaulting to off to preserve existing behavior, that allows a client to specify that the AST is inviolate. This is necessary to address some of the outstanding issues in cmd/doc that require, for example, looking at function bodies.

Prior to stack tracing, inlining could cause dead pointers to be kept alive in some loops. See #18336 and CL 31674. The adjustment removed by this change preserved the inlining status quo in the face of Node structure changes, to avoid creating new problems. Now that stack tracing provides precision, these hacks can be removed. Of course, our inlining code model is already hacky (#17566), but at least now there will be fewer epicyclical hacks.

This change makes use of a VSX instruction to generate the float 0 value instead of generating a constant in memory and loading it from there. This uses 1 instruction instead of 2 and avoids a memory reference. in the +0 case, uses 2 instructions in the -0 case but avoids the memory reference. Since this is done in the assembler for ppc64x, an update has been made to the assembler test.
