The additions were machine-generated. The change for x * 7 avoids a reg-reg move, reducing the number of instructions from 3 to 2.

This change reduces the time to run this test on my machine from real 0m2.491s user 0m3.020s sys 0m0.331s to real 0m0.237s user 0m0.180s sys 0m0.173s This will make it reasonable to add more constants to the test. I am also hopeful that it might help a bit with intermittent cmd/compile/internal/gc test timeouts on the build dashboard on the slower builders. The time savings are entirely in compilation time, by avoiding generating one giant func main. Instead, generate tables of tests to be run, which are translated into static data, and then loop over those tests. While we're here, do some minor cleanup: * Remove the _ssa suffix on function names, as that was only needed during ssa bootstrapping. * Clean up error handling during test generation. * Make functions single-line, to reduce future diff sizes. Diffing giant files is slow.

Don't compile the runtime packages with coverage when using the race detector. The user can, perhaps accidentally, request coverage for the runtime by using -coverpkg=all. If using the race detector, the runtime package coverage will call into the race detector before it has been initialized. This will cause the program to crash mysteriously on startup.

1. STPW stores the lower 32-bit words of a pair of registers to memory. 2. LDPW loads two 32-bit words from memory, zero extends them to 64-bit, and then copies to a pair of registers. 3. LDPSW does the same as LDPW, except a sign extension. This CL implements those 3 instructions and adds test cases.

Spans are represented using Async Event types of chrome trace viewer. According to the doc, the 'id' should be unique within category, scope. https://docs.google.com/document/d/1CvAClvFfyA5R-PhYUmn5OOQtYMH4h6I0nSsKchNAySU/preview#heading=h.jh64i9l3vwa1 Use the index in the task's span slice as the slice id, so it can be unique within the task. The scope is the task id which is unique. This fixes a visualization bug that caused incorrect or missing presentation of nested spans.

Matthew Dempsky authored
In expandmeth, we call expand1/expand0 to build a list of all candidate methods to promote, and then we use dotpath to prune down which names actually resolve to a promoted method and how. However, previously we still computed "followsptr" based on the expand1/expand0 traversal (which is depth-first), rather than dotpath (which is breadth-first). The result is that we could sometimes end up miscomputing whether a particular promoted method involves a pointer traversal, which could result in bad code generation for method trampolines.

Instrumenting the compiler shows that, at the end of liveValues, the values of the workList's cap are distributed as: cap freq 1 0.006 2 0.002 4 0.237 8 0.272 16 0.254 32 0.141 64 0.062 128 0.02 256 0.005 512 0.001 1024 0.0 Since the initial workList slice allocation is always on the stack (as the variable does not escape), we can aggressively pre-allocate a big backing array at (almost) no cost. This will save several allocations in liveValues calls that end up having a large workList, with no performance penalties for calls that have a small workList. name old time/op new time/op delta Template 284ms ± 3% 282ms ± 3% ~ (p=0.201 n=20+20) Unicode 138ms ± 7% 138ms ± 7% ~ (p=0.718 n=20+20) GoTypes 905ms ± 2% 895ms ± 1% -1.10% (p=0.003 n=19+18) Compiler 4.26s ± 1% 4.25s ± 1% -0.38% (p=0.038 n=20+19) SSA 9.85s ± 2% 9.80s ± 1% ~ (p=0.061 n=20+19) Flate 187ms ± 6% 186ms ± 5% ~ (p=0.289 n=20+20) GoParser 227ms ± 3% 225ms ± 3% ~ (p=0.072 n=20+20) Reflect 578ms ± 2% 575ms ± 2% ~ (p=0.059 n=18+20) Tar 263ms ± 2% 265ms ± 3% ~ (p=0.224 n=19+20) XML 323ms ± 3% 325ms ± 2% ~ (p=0.127 n=20+20) name old user-time/op new user-time/op delta Template 406ms ± 6% 404ms ± 4% ~ (p=0.314 n=20+20) Unicode 220ms ± 6% 215ms ±11% ~ (p=0.077 n=18+20) GoTypes 1.25s ± 3% 1.24s ± 4% ~ (p=0.461 n=20+20) Compiler 5.95s ± 2% 5.84s ± 5% -1.93% (p=0.007 n=20+20) SSA 14.4s ± 4% 14.2s ± 4% ~ (p=0.108 n=20+20) Flate 257ms ± 6% 252ms ± 9% ~ (p=0.063 n=20+20) GoParser 317ms ± 5% 312ms ± 6% -1.85% (p=0.049 n=20+20) Reflect 779ms ± 2% 774ms ± 3% ~ (p=0.253 n=20+20) Tar 371ms ± 4% 374ms ± 4% ~ (p=0.327 n=20+20) XML 440ms ± 5% 442ms ± 5% ~ (p=0.678 n=20+20) name old alloc/op new alloc/op delta Template 39.4MB ± 0% 39.0MB ± 0% -0.96% (p=0.000 n=20+20) Unicode 29.1MB ± 0% 29.0MB ± 0% -0.13% (p=0.000 n=20+20) GoTypes 117MB ± 0% 116MB ± 0% -0.88% (p=0.000 n=20+20) Compiler 502MB ± 0% 498MB ± 0% -0.77% (p=0.000 n=19+20) SSA 1.42GB ± 0% 1.40GB ± 0% -0.80% (p=0.000 n=20+20) Flate 25.3MB ± 0% 25.0MB ± 0% -1.10% (p=0.000 n=20+19) GoParser 31.3MB ± 0% 31.0MB ± 0% -1.05% (p=0.000 n=20+20) Reflect 77.9MB ± 0% 77.1MB ± 0% -1.03% (p=0.000 n=20+20) Tar 40.0MB ± 0% 39.7MB ± 0% -0.80% (p=0.000 n=20+20) XML 45.2MB ± 0% 44.9MB ± 0% -0.72% (p=0.000 n=20+20) name old allocs/op new allocs/op delta Template 392k ± 0% 386k ± 0% -1.44% (p=0.000 n=20+20) Unicode 337k ± 0% 337k ± 0% -0.22% (p=0.000 n=20+20) GoTypes 1.22M ± 0% 1.20M ± 0% -1.33% (p=0.000 n=20+20) Compiler 4.76M ± 0% 4.71M ± 0% -1.12% (p=0.000 n=20+20) SSA 11.8M ± 0% 11.7M ± 0% -1.00% (p=0.000 n=20+20) Flate 241k ± 0% 238k ± 0% -1.49% (p=0.000 n=20+20) GoParser 324k ± 0% 320k ± 0% -1.17% (p=0.000 n=20+20) Reflect 981k ± 0% 961k ± 0% -2.11% (p=0.000 n=20+20) Tar 402k ± 0% 397k ± 0% -1.29% (p=0.000 n=20+20) XML 424k ± 0% 419k ± 0% -1.10% (p=0.000 n=19+20) Change-Id: If46667ae98eee2d47a615cad05e18df0629d8388 Reviewed-on: https://go-review.googlesource.com/102495 Run-TryBot: Alberto Donizetti <alb.donizetti@gmail.com> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by:

CL 102457 added TestDevNullFile. However, this test is failing on Plan 9, because it checks that /dev/null is a character device while there are no special files on Plan 9. We fix this issue by changing Stat to consider all files served by the console device (#c) as character devices. Fixes #24534.

I grepped for "bytes.Buffer" and "buf.String" and mostly ignored test files. I skipped a few on purpose and probably missed a few others, but otherwise I think this should be most of them.

The documentation was unclear here and I misremembered the behaviour and changed it in 1.10: it used to be that matching any EKU was enough but 1.10 requires that all EKUs match. Restore 1.9 behaviour and clarify the documentation to make it official. Fixes #24162.

The way Value.AuxInt represents unsigned numbers is currently documented in genericOps.go, which is not the most obvious place for it. Move that documentation to Value.AuxInt. Furthermore, to make it harder to use incorrectly, introduce a Value.AuxUnsigned accessor that returns the zero-extended value of Value.AuxInt.

Even though GOARCH=sparc64 is not supported by gc (yet), it is easy to make cgo already support it. This e.g. allows to generate Go type definitions for linux/sparc64 in the golang.org/x/sys/unix package without using gccgo.

Gdb can be sensitive to contents of .gdbinit, and to run this test properly needs to have runtime/runtime-gdb.py on the auto load safe path. Therefore, turn off .gdbinit loading and explicitly add $GOROOT/runtime to the safe load path. This should make ssa/debug_test.go run more consistently. Updates #24464.

A newish check for branch-likely on single-successor blocks caught a case where the preemption-check inserter was setting "likely" on an unconditional branch. Fixed by checking for that case before setting likely. Also removed an overconservative restriction on parallel compilation for GOEXPERIMENT=preemptibleloops; it works fine, it is just another control-flow transformation.

We use 32-bit operations for 8- and 16-bit arithmetic, so use them for comparisons too. This won't change performance but it is more consistent and makes testing 8- and 16-bit comparison codegen slightly more straightforward (for follow up CL). Also fix a typo and add some additional double sign and zero extension rules to remove the operations inserted by the comparison rules.
