"Division by invariant integers using multiplication" paper by Granlund and Montgomery contains a method for directly computing divisibility (x%c == 0 for c constant) by means of the modular inverse. The method is further elaborated in "Hacker's Delight" by Warren Section 10-17 This general rule can compute divisibilty by one multiplication, and add and a compare for odd divisors and an additional rotate for even divisors. To apply the divisibility rule, we must take into account the rules to rewrite x%c = x-((x/c)*c) and (x/c) for c constant on the first optimization pass "opt". This complicates the matching as we want to match only in the cases where the result of (x/c) is not also needed. So, we must match on the expanded form of (x/c) in the expression x == c*(x/c) in the "late opt" pass after common subexpresion elimination. Note, that if there is an intermediate opt pass introduced in the future we could simplify these rules by delaying the magic division rewrite to "late opt" and matching directly on (x/c) in the intermediate opt pass. On amd64, the divisibility check is 30-45% faster. name old time/op new time/op delta` DivisiblePow2constI64-4 0.83ns ± 1% 0.82ns ± 0% ~ (p=0.079 n=5+4) DivisibleconstI64-4 2.68ns ± 1% 1.87ns ± 0% -30.33% (p=0.000 n=5+4) DivisibleWDivconstI64-4 2.69ns ± 1% 2.71ns ± 3% ~ (p=1.000 n=5+5) DivisiblePow2constI32-4 1.15ns ± 1% 1.15ns ± 0% ~ (p=0.238 n=5+4) DivisibleconstI32-4 2.24ns ± 1% 1.20ns ± 0% -46.48% (p=0.016 n=5+4) DivisibleWDivconstI32-4 2.27ns ± 1% 2.27ns ± 1% ~ (p=0.683 n=5+5) DivisiblePow2constI16-4 0.81ns ± 1% 0.82ns ± 1% ~ (p=0.135 n=5+5) DivisibleconstI16-4 2.11ns ± 2% 1.20ns ± 1% -42.99% (p=0.008 n=5+5) DivisibleWDivconstI16-4 2.23ns ± 0% 2.27ns ± 2% +1.79% (p=0.029 n=4+4) DivisiblePow2constI8-4 0.81ns ± 1% 0.81ns ± 1% ~ (p=0.286 n=5+5) DivisibleconstI8-4 2.13ns ± 3% 1.19ns ± 1% -43.84% (p=0.008 n=5+5) DivisibleWDivconstI8-4 2.23ns ± 1% 2.25ns ± 1% ~ (p=0.183 n=5+5) Fixes #30282 Fixes #15806 Change-Id: Id20d78263a4fdfe0509229ae4dfa2fede83fc1d0 Reviewed-on: https://go-review.googlesource.com/c/go/+/173998 Run-TryBot: Brian Kessler <brian.m.kessler@gmail.com> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by:

The spec carefully and consistently uses "key" and "element" as map terminology. The implementation, not so much. This change attempts to make the implementation consistently hew to the spec's terminology. Beyond consistency, this has the advantage of avoid some confusion and naming collisions, since v and value are very generic and commonly used terms. I believe that I found all everything, but there are a lot of non-obvious places for these to hide, and grepping for them is hard. Hopefully this change changes enough of them that we will start using elem going forward. Any remaining hidden cases can be removed ad hoc as they are discovered. The only externally-facing part of this change is in package reflect, where there is a minor doc change and a function parameter name change.

We use Wasm global variables extensively for simulating registers, especially SP. V8 does not handle global variables efficiently. This CL reduces global variable accesses by caching the global SP in a local variable in each function. The local cache is set on function entry and updated after each call (where the stack could have moved). Within a function, the SP access will use the local variable.

For the code: m := map[int]int { a(): b(), c(): d(), e(): f(), } We used to do: t1 := a() t2 := b() t3 := c() t4 := d() t5 := e() t6 := f() m := map[int]int{} m[t1] = t2 m[t3] = t4 m[t5] = t6 After this CL we do: m := map[int]int{} t1 := a() t2 := b() m[t1] = t2 t3 := c() t4 := d() m[t3] = t4 t5 := e() t6 := f() m[t5] = t6 Ordering the initialization this way limits the lifetime of the temporaries involved. In particular, for large maps the number of simultaneously live temporaries goes from ~2*len(m) to ~2. This change makes the compiler (regalloc, mostly) a lot happier. The compiler runs faster and uses a lot less memory. For #26546, changes compile time of a big map from 8 sec to 0.5 sec.

When a callback runs on a different thread in Windows, as in the runtime package test TestCallbackInAnotherThread, it will use the extra M. That can cause the test in checkdead to fail incorrectly. Check whether there actually is an extra M before expecting it. I think this is a general problem unrelated to timers. I think the test was passing previously because the timer goroutine was using an M. But I haven't proved that. This change seems correct, and it avoids the test failure when using the new timers on Windows.

Most of the platforms are returning 0 instead of -1 when mmap syscalls is failing. This patch corrects it for AIX in order to fix TestMmapErrorSign and to improve AIX compatibility.

Any code that imports the testing package forces the testing flags to be defined, even in non-test binaries. People work around this today by defining a copy of the testing.TB interface just to avoid importing testing. Fix this by moving flag registration into a new function, testing.Init. Delay calling Init until the testing binary begins to run, in testing.MainStart. Init is exported for cases where users need the testing flags to be defined outside of a "go test" context. In particular, this may be needed where testing.Benchmark is called outside of a test.

OpenBSD does not provide auxv, however we still need to initialise cpu.HWCap. For now initialise it to the bare minimum, until some form of CPU capability detection is implemented or becomes available - see issue #31746.
