This abstracts creation of ACALL Progs into package gc. The main benefit of this today is we can refactor away a lot of common boilerplate code. Later, once liveness analysis happens on the SSA graph, this will also provide an easy insertion point for emitting the PCDATA Progs immediately before call instructions. Passes toolstash-check -all.

Tinkering with the gob package shows that is currently possible to *completely destroy* Int slices encoding without triggering a single test failure. The various encInt{8,16,32,64}Slice methods are only called during the execution of the GobMapInterfaceEncode test, which only encodes a few slices of length exactly 1 and then just checks that the error returned by Encode is nil (without trying to Decode back the data). This patch adds a few tests for signed integer slices encoding. Change-Id: Ifaaee2f32132873118b241f79aa8203e4ad31416 Reviewed-on: https://go-review.googlesource.com/38066Reviewed-by: -

Move the zeroing of results earlier. In particular, they need to come before any move-to-heap operations, as those require allocation. Those allocations are points at which the GC can see the uninitialized result slots. For the function: func f() (x, y, z *int) { defer(){}() escape(&y) return } We used to generate code like this: x = nil y = nil &y = new(int) z = nil Now we will generate: x = nil y = nil z = nil &y = new(int) Since the fix for #18860, the return slots are always live if there is a defer, so the former ordering allowed the GC to see junk in the z slot.

The existing implementation started by eliminating nil checks for OpAddr, OpAddPtr, and OpPhis with all non-nil args. However, some OpPhis had all non-nil args, but their args had not been processed yet. Pull the OpPhi checks into their own loop, and repeat until stabilization. Eliminates a dozen additional nilchecks during make.bash. Negligible compiler performance impact.

With this change, code like h := sha1.New() h.Write(buf) sum := h.Sum() gets compiled into static calls rather than interface calls, because the compiler is able to prove that 'h' is really a *sha1.digest. The InterCall re-write rule hits a few dozen times during make.bash, and hundreds of times during all.bash. The most common pattern identified by the compiler is a constructor like func New() Interface { return &impl{...} } where the constructor gets inlined into the caller, and the result is used immediately. Examples include {sha1,md5,crc32,crc64,...}.New, base64.NewEncoder, base64.NewDecoder, errors.New, net.Pipe, and so on. Some existing benchmarks that change on darwin/amd64: Crc64/ISO4KB-8 2.67µs ± 1% 2.66µs ± 0% -0.36% (p=0.015 n=10+10) Crc64/ISO1KB-8 694ns ± 0% 690ns ± 1% -0.59% (p=0.001 n=10+10) Adler32KB-8 473ns ± 1% 471ns ± 0% -0.39% (p=0.010 n=10+9) On architectures like amd64, the reduction in code size appears to contribute more to benchmark improvements than just removing the indirect call, since that branch gets predicted accurately when called in a loop.

nat.setUint64 is nicely generic. By assuming 32- or 64-bit words, however, we can write simpler code, and eliminate some shifts in dead code that vet complains about. Generated code for 64 bit systems is unaltered. Generated code for 32 bit systems is much better. For 386, the routine length drops from 325 bytes of code to 271 bytes of code, with fewer loops.

The compiler recognizes that in a sequence q = x/y; r = x%y only one division is required. Remove prior work-arounds and write more readable straight-line code (this also results in fewer instructions, though it doesn't appear to affect the benchmarks significantly). name old time/op new time/op delta FormatInt-8 2.95µs ± 1% 2.92µs ± 5% ~ (p=0.952 n=5+5) AppendInt-8 1.91µs ± 1% 1.89µs ± 2% ~ (p=0.421 n=5+5) FormatUint-8 795ns ± 2% 782ns ± 4% ~ (p=0.444 n=5+5) AppendUint-8 557ns ± 1% 557ns ± 2% ~ (p=0.548 n=5+5) https://perf.golang.org/search?q=upload:20170310.1 Also: - use uint instead of uintptr where we want to guarantee single- register operations - remove some unnecessary conversions (before indexing) - add more comments and fix some comments Change-Id: I04858dc2d798a6495879d9c7cfec2fdc2957b704 Reviewed-on: https://go-review.googlesource.com/38071Reviewed-by:

In FreeBSD when run Go proc under a given sub-list of processors(e.g. 'cpuset -l 0 ./a.out' in multi-core system), runtime.NumCPU() still return all physical CPUs from sysctl hw.ncpu instead of account from sub-list. Fix by use syscall cpuset_getaffinity to account the number of sub-list.

We are vendoring pprof from github.com/google/pprof, which comes with a main package. If we don't explicitly skip that main package, then `go install cmd` will install the compiled program in $GOROOT/bin. Fixes #19441.

It appears that this test is particularly sensitive to resource starvation. Returning it to non-parallel should reduce flakiness, by giving it the full system resources to run.

They accounted for almost 30% of all CSE'd values. By never creating the duplicates in the first place, we reduce the high water mark of Value IDs, which in turn makes all SSA phases cheaper, particularly regalloc. name old time/op new time/op delta Template 200ms ± 3% 198ms ± 4% -0.87% (p=0.016 n=50+49) Unicode 86.9ms ± 2% 85.5ms ± 3% -1.56% (p=0.000 n=49+50) GoTypes 553ms ± 4% 551ms ± 4% ~ (p=0.183 n=50+49) SSA 3.97s ± 3% 3.93s ± 2% -1.06% (p=0.000 n=48+48) Flate 124ms ± 4% 124ms ± 3% ~ (p=0.545 n=48+50) GoParser 146ms ± 4% 146ms ± 4% ~ (p=0.810 n=49+49) Reflect 357ms ± 3% 355ms ± 3% -0.59% (p=0.049 n=50+48) Tar 106ms ± 4% 107ms ± 5% ~ (p=0.454 n=49+50) XML 203ms ± 4% 203ms ± 4% ~ (p=0.726 n=48+50) name old user-ns/op new user-ns/op delta Template 237M ± 3% 235M ± 4% ~ (p=0.208 n=47+48) Unicode 111M ± 4% 108M ± 9% -2.50% (p=0.000 n=47+50) GoTypes 736M ± 5% 729M ± 4% -0.95% (p=0.017 n=50+46) SSA 5.73G ± 4% 5.74G ± 4% ~ (p=0.765 n=50+50) Flate 150M ± 5% 148M ± 6% -0.89% (p=0.045 n=48+47) GoParser 180M ± 5% 178M ± 7% -1.34% (p=0.012 n=50+50) Reflect 450M ± 4% 444M ± 4% -1.40% (p=0.000 n=50+49) Tar 124M ± 7% 123M ± 7% ~ (p=0.092 n=50+50) XML 248M ± 6% 245M ± 5% ~ (p=0.057 n=50+50) name old alloc/op new alloc/op delta Template 39.4MB ± 0% 39.3MB ± 0% -0.37% (p=0.000 n=50+50) Unicode 30.9MB ± 0% 30.9MB ± 0% -0.27% (p=0.000 n=48+50) GoTypes 114MB ± 0% 113MB ± 0% -1.03% (p=0.000 n=50+49) SSA 882MB ± 0% 865MB ± 0% -1.95% (p=0.000 n=49+49) Flate 25.8MB ± 0% 25.7MB ± 0% -0.21% (p=0.000 n=50+50) GoParser 31.7MB ± 0% 31.6MB ± 0% -0.33% (p=0.000 n=50+50) Reflect 79.7MB ± 0% 79.3MB ± 0% -0.49% (p=0.000 n=44+49) Tar 27.2MB ± 0% 27.1MB ± 0% -0.31% (p=0.000 n=50+50) XML 42.7MB ± 0% 42.3MB ± 0% -1.05% (p=0.000 n=48+49) name old allocs/op new allocs/op delta Template 379k ± 1% 380k ± 1% +0.26% (p=0.000 n=50+50) Unicode 324k ± 1% 324k ± 1% ~ (p=0.964 n=49+50) GoTypes 1.14M ± 0% 1.15M ± 0% +0.14% (p=0.000 n=50+49) SSA 7.89M ± 0% 7.89M ± 0% -0.05% (p=0.000 n=49+49) Flate 240k ± 1% 241k ± 1% +0.27% (p=0.001 n=50+50) GoParser 310k ± 1% 311k ± 1% +0.48% (p=0.000 n=50+49) Reflect 1.00M ± 0% 1.00M ± 0% +0.17% (p=0.000 n=48+50) Tar 254k ± 1% 255k ± 1% +0.23% (p=0.005 n=50+50) XML 395k ± 1% 395k ± 1% +0.19% (p=0.002 n=49+47) Change-Id: Iaa8f5f37e23bd81983409f7359f9dcd4dfe2961f Reviewed-on: https://go-review.googlesource.com/38003 Run-TryBot: Josh Bleecher Snyder <josharian@gmail.com> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by:
