cmd/compile: inline known-size memclrNoHeapPointers calls
This patch rewrites known-size calls to memclrNoHeapPointers with an OpZero.
This significantly improves performance and lets some clears get DSE'd.
One of the cases where this applies is zeroing a known-size array, example:
var x [256]int8
...
for a := range x {
x[a] = 0
}
Other cases can be found in the runtime itself where memclrNoHeapPointers is sometimes directly invoked with a constant.
It seems that for some sized-clears on some architectures (AMD64, maybe others) the memcrlNoHeapPointers is more performant than OpZero.
See the issue #56997 for more details.

io: allocate copy buffers from a pool
CopyBuffer allocates a 32k buffer when no buffer is available. Allocate these buffers from a sync.Pool. This removes an optimization where the copy buffer size was reduced when the source is a io.LimitedReader (including the case of CopyN) with a limit less than the default buffer size. This change could cause a program which only uses io.Copy with sources with a small limit to allocate unnecessarily large buffers. Programs which care about the transient buffer allocation can avoid this by providing their own buffer. name old time/op new time/op delta CopyNSmall-10 165ns ± 7% 117ns ± 7% -29.19% (p=0.001 n=7+7) CopyNLarge-10 7.33µs ±34% 4.07µs ± 2% -44.52% (p=0.001 n=7+7) name old alloc/op new alloc/op delta CopyNSmall-10 2.20kB ±12% 1.20kB ± 4% -45.24% (p=0.000 n=8+7) CopyNLarge-10 148kB ± 9% 81kB ± 4% -45.26% (p=0.000 n=8+7) name old allocs/op new allocs/op delta CopyNSmall-10 2.00 ± 0% 1.00 ± 0% -50.00% (p=0.000 n=8+8) CopyNLarge-10 2.00 ± 0% 1.00 ± 0% -50.00% (p=0.000 n=8+8) For #57202 Change-Id: I2292226da9ba1dc09a2543f5d74fe5da06080d49 Reviewed-on: https://go-review.googlesource.com/c/go/+/456555 TryBot-Result: Gopher Robot <gobot@golang.org> Run-TryBot: Damien Neil <dneil@google.com> Reviewed-by: Thomas Austad <thomas.austad@gmail.com> Auto-Submit: Damien Neil <dneil@google.com> Reviewed-by: Ian Lance Taylor <iant@google.com> |

cmd/dist: leave cgo enabled if external linking is required
Certain ios and android configurations do not yet support internal linking. On ios, attempting to build without cgo causes tests to fail on essentially every run (#57961). On android, it produces a lot of warning spam from the linker, obscuring real problems. Since external linking makes the result of `go install` depend on the installed C toolchain either way, the reproducibility benefit of disabling cgo seems minimal on these platforms anyway. Fixes #57961. For #24904. Updates #57007.

cmd/internal/obj/x86: use push/pop instead of mov to store/load FP
This CL changes how the x86 compiler stores and loads the frame pointer on each function prologue and epilogue, with the goal to reduce the final binary size without affecting performance. The compiler is currently using MOV instructions to load and store BP, which can take from 5 to 8 bytes each. This CL changes this approach so it emits PUSH/POP instructions instead, which always take only 1 byte each (when operating with BP). It can also avoid using the SUBQ/ADDQ to grow the stack for functions that have frame pointer but does not have local variables. On Windows, this CL reduces the go toolchain size from 15,697,920 bytes to 15,584,768 bytes, a reduction of 0.7%. Example of epilog and prologue for a function with 0x10 bytes of local variables: Before === SUBQ $0x18, SP MOVQ BP, 0x10(SP) LEAQ 0x10(SP), BP ... function body ... MOVQ 0x10(SP), BP ADDQ $0x18, SP RET === After === PUSHQ BP LEAQ 0(SP), BP SUBQ $0x10, SP ... function body ...

cmd/dist: skip rebuilding packages during builder testing
Since packages in "std" no longer have install targets, checking them for staleness is somewhat meaningless: if they are not cached they will be rebuilt anyway, and without installed archives against which we can compare them the staleness check will not detect builder skew. It would still be meaningful to check "cmd" for staleness, but (especially on sharded VM-based builders) that is a fairly expensive operation relative to its benefit. If we are really interested in detecting builder skew and/or build reproducibility, we could instead add a "misc" test (similar to "misc/reboot", or perhaps even a part of that test) that verifies that bootstrapped binaries are reproducible.

internal/poll: don't queue port completion entry for udp on windows
This CL sets the FILE_SKIP_COMPLETION_PORT_ON_SUCCESS notification mode for all udp and tcp networks. When SetFileCompletionNotificationModes was implemented, back in go 1.2 [1], it was not possible to enable this mode on udp connections because it is buggy on Windows 7 and earlier. The bug was fixed on Windows 8. We can safely enable this mode now, since go 1.21 will require Windows 10 or higher. While here, I noticed that this mode is only enabled for tcp, but not for tcp4 nor tcp6. I don't think this restriction makes sense, so I'm lifting it.

This generates GetTempPath2. Go now tries to determine if the windows it runs on has GetTempPath2 by finding it only once at the loading time. If GetTempPath2 exists, it sets the flag so that any calls to tempDir will use it. If it doesn't exist, Go then uses GetTempPath.
GetTempPath2 was generated into internal/syscall/windows since syscall is locked down.

os: fix findOneDriveDir to expand strings that contain environment variables
On Windows the registry data type REG_EXPAND_SZ indicates that the string requires expansion of environment variables. The existing implementation doesn't take that into consideration and just returns the unexpanded string, ignoring the registry type. This implementation ensures that environment variables are properly expanded when needed.

cmd/compile: fix -m=2 output for recursive function with closures
ir.VisitFuncsBottomUp returns recursive==true for functions which call themselves. It also returns any closures inside that function. We don't want to report the closures as recursive, as they really aren't. Only the containing function is recursive.

test/codegen: merge identical ppc64 and ppc64le tests
Manually consolidate the remaining ppc64/ppc64le test which are not so trivial to automatically merge. The remaining ppc64le tests are limited to cases where load/stores are merged (this only happens on ppc64le) and the race detector (only supported on ppc64le).
