6cb107452a runtime: print fatal messages without interleaving
Grab the print lock around the set of prints we use to report
fatal errors. This ensures that each fatal error gets reported
atomically instead of interleaved with other fatal errors.

Fixes #69447

Preparation for removing the existing non-standard iterators
(is, underIs). Note that we cannot use typeset iterators in

While at it, move underIs from expr.go to under.go
and adjust some doc strings in typset.go to match
prevailing style in that file.

No test case for un-instantiated generic type Alias type
string: there's no existing test framework, the code is
identical as for Named types, and these strings only appear
in tracing output. Tested manually.

89a5a60da6 internal/trace: refactor Stack.Frames to return iter.Seq
The Frames function is almost an iter.Seq, except for its bool return
value.

Since none of the callers in the Go tree rely on the bool, we can remove
it. However, doing so might still obscure the intended usage as an iterator.

This refactor changes the API to return iter.Seq, making the intended
usage explicit. Refactoring the existing callers to take advantage of
the new interface will be done in a follow-up CL.

7c72dc77a9 cmd/go: skip TestScript on Plan 9 in short mode
TestScript is very slow on Plan 9 because this test
is particularly i/o intensive.

This is leading the plan9/386 and plan9/amd64 builders
to time out. This test was already skipped on plan9/arm
because arm is part of the "slow architectures" list.

This change skips TestScript on Plan 9 on short mode.

402dc98759 testing: enable better loop time measurement for benchmarking.
With b.Loop() in place, the time measurement of loop scaling could be improved to be tighter. By identifying the first call to b.Loop(), we can avoid measuring the expensive ramp-up time by reset the timer tightly before the loop starts. The remaining loop scaling logic of b.N style loop is largely reused.

For #61515.

7ba074fe43 reflect: remove calling mapiterkey, mapiterelem
It makes use of the hiter structure which matches runtime.hiter's.

This change mainly improves the performance of Next method of MapIter.

goos: darwin
goarch: arm64
pkg: reflect
cpu: Apple M2
              │  ./old.txt  │              ./new.txt              │
              │   sec/op    │   sec/op     vs base                │
MapIterNext-8   61.95n ± 0%   54.95n ± 0%  -11.28% (p=0.000 n=10)

for the change of `test/escape_reflect.go`:
removing mapiterkey, mapiterelem would cause leaking MapIter content
when calling SetIterKey and SetIterValue,
and this may cause map bucket to be allocated on heap instead of stack.
Reproduce:
```
{
  m := map[int]int{1: 2} // escapes to heap after this change
  it := reflect.ValueOf(m).MapRange()
  it.Next()
  var k, v int
  reflect.ValueOf(&k).Elem().SetIterKey(it)
  reflect.ValueOf(&v).Elem().SetIterValue(it)
  println(k, v)
}
```
This CL would not introduce abi.NoEscape to fix this. It may need futher
optimization and tests on hiter field usage and its escape analysis.

Fixes #69416

This CL introduces the ability to print information about the toolchain switch used in the
go command, controlled by the `toolchaintrace` setting. This setting defaults to `toolchaintrace=0`,
meaning no information is printed. Setting it to `toolchaintrace=1` will cause the go command
to print a message indicating the toolchain used and where it was found.

db40d1a4c4 cmd/compile: fix wrong esacpe analysis for rangefunc
CL 584596 "-range<N>" suffix to the name of closure generated for a
rangefunc loop body. However, this breaks the condition that escape
analysis uses for checking whether a closure contains within function,
which is "F.funcN" for outer function "F" and closure "funcN".

Fixing this by adding new "-rangeN" to the condition.
