The environment variables used in those tests override the default OS ones. However, one of them (SystemRoot) seems to be required on some Windows systems for invoking cmd.exe properly.

When running benchmarks with -cpuprofile, the entire process gets profiled, and ReadMemStats is surprisingly expensive. Running the sort benchmarks right now with -cpuprofile shows almost half of all execution time in ReadMemStats. Since ReadMemStats is not required if the benchmark does not need allocation stats, simply skip it. This will make cpu profiles nicer to read and significantly speed up the process of running benchmarks. It might also make sense to toggle cpu profiling on/off as we begin/end individual benchmarks, but that wouldn't get us the time savings of skipping ReadMemStats, so this CL is useful in itself.

The 0x10101 magic constant is a little more principled than 0x10100, as the rounding adjustment now spans the complete range [0, 0xffff] instead of [0, 0xff00]. Consider this round-tripping code: y, cb, cr := color.RGBToYCbCr(r0, g0, b0) r1, g1, b1 := color.YCbCrToRGB(y, cb, cr) Due to rounding errors both ways, we often but not always get a perfect round trip (where r0 == r1 && g0 == g1 && b0 == b1). This is true both before and after this commit. In some cases we got luckier, in others we got unluckier. For example, before this commit, (180, 135, 164) doesn't round trip perfectly (it's off by 1) but (180, 135, 165) does. After this commit, both cases are reversed: the former does and the latter doesn't (again off by 1). Over all possible (r, g, b) triples, there doesn't seem to be a big change for better or worse. There is some history in these CLs: image/color: tweak the YCbCr to RGBA conversion formula. https://go-review.googlesource.com/#/c/12220/2/src/image/color/ycbcr.go image/color: have YCbCr.RGBA work in 16-bit color, per the Color interface. https://go-review.googlesource.com/#/c/8073/2/src/image/color/ycbcr.go Change-Id: Ib25ba7039f49feab2a9d1a4141b86db17db7b3e1 Reviewed-on: https://go-review.googlesource.com/36732 Run-TryBot: Nigel Tao <nigeltao@golang.org> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by:

During the mark phase of garbage collection, goroutines that allocate may be recruited to assist. This change creates trace events for mark assists and displays them similarly to sweep assists in the trace viewer. Mark assists are different than sweeps in that they can be preempted, so displaying them in the trace viewer is a little tricky -- we may need to synthesize multiple slices for one mark assist. This could have been done in the parser instead, but I thought it might be preferable to keep the parser as true to the event stream as possible.

The s390x port was based on the ppc64 port and, because of the way the port was done, inherited some instructions from it. ppc64 supports 3-operand (4-operand for FMADD etc.) floating point instructions but s390x doesn't (the destination register is always an input) and so these were emulated. There is a bug in the emulation of FMADD whereby if the destination register is also a source for the multiplication it will be clobbered. This doesn't break any assembly code in the std lib but could affect future work. To fix this I have gone through the floating point instructions and removed all unnecessary 3-/4-operand emulation. The compiler doesn't need it and assembly writers don't need it, it's just a source of bugs. I've also deleted the FNMADD family of emulated instructions. They aren't used anywhere.

This is a re-roll of a previous commit, a855da29, which was rolled back in 14347ee4. It was rolled back because it broke a unit test in image/gif. The image/gif code was fixed by 9ef65dbe "image/gif: fix frame-inside-image bounds checking". The original commit message: image: fix the overlap check in Rectangle.Intersect. The doc comment for Rectangle.Intersect clearly states, "If the two rectangles do not overlap then the zero rectangle will be returned." Prior to this fix, calling Intersect on adjacent but non-overlapping rectangles would return an empty but non-zero rectangle. The fix essentially changes if r.Min.X > r.Max.X || r.Min.Y > r.Max.Y { etc } to if r.Min.X >= r.Max.X || r.Min.Y >= r.Max.Y { etc } (note that the > signs have become >= signs), but changing that line to: if r.Empty() { etc } seems clearer (and equivalent).

However, there is one class of runtime routines that do not actually need an addressable value: fast map access routines. This CL teaches order.go to avoid using static variables for addressability in those cases. Instead, it avoids introducing a temp at all, which the backend would just have to optimize away.

The semantics of the Go image.Rectangle type is that the In and Intersects methods treat empty rectangles specially. There are multiple valid representations of an empty image.Rectangle. One of them is the zero image.Rectangle but there are others. They're obviously not all equal in the == sense, so we shouldn't use != to check GIF's semantics.

The current implementation fails to produce an "IsNotExist" error on some platforms (unix) for certain situations where it would be expected. This causes downstream consumers, like FileServer, to emit 500 errors instead of a 404 for some non-existant paths on certain platforms but not others. As an example, os.Open("/index.html/foo") on a unix-type system will return syscall.ENOTDIR, which os.IsNotExist cannot return true for (because the error code is ambiguous without context). On windows, this same example would result in os.IsNotExist returning true -- since the returned error is specific. This change alters Dir.Open to look up the tree for an "IsPermission" or "IsNotExist" error to return, or a non-directory, returning os.ErrNotExist in the last case. For all other error scenarios, the original error is returned. This ensures that downstream code, like FileServer, receive errors that behave the same across all platforms.

The gcCompat mode was introduced to match the new parser's node position setup exactly with the positions used by the original parser. Some of the gcCompat adjustments were required to satisfy syntax error test cases, and the rest were required to make toolstash cmp pass. This change removes the former gcCompat adjustments and instead adjusts the respective test cases as necessary. In some cases this makes the error lines consistent with the ones reported by gccgo. Where it has changed, the position associated with a given syntactic construct is the position (line/col number) of the left-most token belonging to the construct.

Avoid populating it twice. * Don't bother populating auxmap for values that can't be CSE'd anyway. name old alloc/op new alloc/op delta Template 41.0MB ± 0% 40.7MB ± 0% -0.61% (p=0.008 n=5+5) Unicode 32.3MB ± 0% 32.3MB ± 0% -0.22% (p=0.008 n=5+5) GoTypes 122MB ± 0% 121MB ± 0% -0.55% (p=0.008 n=5+5) Compiler 482MB ± 0% 479MB ± 0% -0.58% (p=0.008 n=5+5) SSA 865MB ± 0% 862MB ± 0% -0.35% (p=0.008 n=5+5) Flate 26.5MB ± 0% 26.5MB ± 0% ~ (p=0.056 n=5+5) GoParser 32.6MB ± 0% 32.4MB ± 0% -0.58% (p=0.008 n=5+5) Reflect 84.2MB ± 0% 83.8MB ± 0% -0.57% (p=0.008 n=5+5) Tar 27.7MB ± 0% 27.6MB ± 0% -0.37% (p=0.008 n=5+5) XML 44.7MB ± 0% 44.5MB ± 0% -0.53% (p=0.008 n=5+5) name old allocs/op new allocs/op delta Template 373k ± 0% 373k ± 1% ~ (p=1.000 n=5+5) Unicode 326k ± 0% 325k ± 0% ~ (p=0.548 n=5+5) GoTypes 1.16M ± 0% 1.16M ± 0% ~ (p=0.841 n=5+5) Compiler 4.16M ± 0% 4.15M ± 0% ~ (p=0.222 n=5+5) SSA 7.57M ± 0% 7.56M ± 0% -0.22% (p=0.008 n=5+5) Flate 238k ± 1% 239k ± 1% ~ (p=0.690 n=5+5) GoParser 304k ± 0% 304k ± 0% ~ (p=1.000 n=5+5) Reflect 1.01M ± 0% 1.00M ± 0% -0.31% (p=0.016 n=4+5) Tar 245k ± 0% 245k ± 1% ~ (p=0.548 n=5+5) XML 393k ± 0% 391k ± 1% ~ (p=0.095 n=5+5) Change-Id: I78f1ffe129bd8fd590b7511717dd2bf9f5ecbd6d Reviewed-on: https://go-review.googlesource.com/36690 Run-TryBot: Josh Bleecher Snyder <josharian@gmail.com> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by:

There's no need to hold the handshake lock across this call and it can lead to deadlocks if the net.Conn calls back into the tls.Conn. Fixes #18426.

Currently there are cases where an XOR with -1 followed by an AND is generanted when it could be done with just an ANDN instruction. Changes to PPC64.rules and required files allows this change in generated code. Examples of this occur in sha3 among others.

This ensures that SIGPROF is handled correctly when using runtime/pprof in a c-archive or c-shared library. Separate profiler handling into pre-process changes and per-thread changes. Simplify the Windows code slightly accordingly. Fixes #18220.
