cmd/compile: inline constant sized memclrNoHeapPointers calls on PPC64
Update the function isInlinableMemclr for ppc64 and ppc64le to enable inlining for the constant sized cases < 512. Larger cases can use dcbz which performs better but requires alignment checking so it is best to continue using memclrNoHeapPointers for those cases.

cmd/compile: fix wrong escape analysis for go/defer generic calls
For go/defer calls like "defer f(x, y)", the compiler rewrites it to:
x1, y1 := x, y
defer func() { f(x1, y1) }()
However, if "f" needs runtime type information, the "RType" field will
refer to the outer ".dict" param, causing wrong liveness analysis.
To fix this, if "f" refers to outer ".dict", the dict param will be
copied to an autotmp, and "f" will refer to this autotmp instead.
Fixes #58341

cmd/compile: fix inline static init arguments substitued tree
Blank node must be ignored when building arguments substitued tree.
Otherwise, it could be used to replace other blank node in left hand
side of an assignment, causing an invalid IR node.
Consider the following code:
type S1 struct {
s2 S2
}
type S2 struct{}
func (S2) Make() S2 {
return S2{}
}
func (S1) Make() S1 {
return S1{s2: S2{}.Make()}
}
var _ = S1{}.Make()
After staticAssignInlinedCall, the assignment becomes:
var _ = S1{s2: S2{}.Make()}
and the arg substitued tree is "map[*ir.Name]ir.Node{_: S1{}}". Now,
when doing static assignment, if there is any assignment to blank node,
for example:
_ := S2{}
That blank node will be replaced with "S1{}":
S1{} := S2{}
So constructing an invalid IR which causes the ICE.

cmd/compile: ensure first instruction in a function is not inlined
People are using this to get the name of the function from a function type: runtime.FuncForPC(reflect.ValueOf(fn).Pointer()).Name() Unfortunately, this technique falls down when the first instruction of the function is from an inlined callee. Then the expression above gets you the name of the inlined function instead of the function itself. To fix this, ensure that the first instruction is never from an inlinee. Normally functions have prologs so those are already fine. In just the cases where a function is a leaf with no local variables, and an instruction from an inlinee appears first in the prog list, add a nop at the start of the function to hold a non-inlined position. Consider the nop a "mini-prolog" for leaf functions.

cmd/compile: add rules to emit SETBC/R instructions on power10
This CL adds rules that replaces instances of ISEL that produce a boolean result based on a condition register by SETBC/SETBCR operations. On Power10 these are convereted to SETBC/SETBCR instructions that use one register instead of 3 registers conventionally used by ISEL and hence reduces register pressure. On loops written specifically to exercise such instances of ISEL extensively, a performance improvement of 2.5% is seen on Power10. Also added verification tests to verify correct generation of SETBC/SETBCR instructions on Power10.

cmd/compile: schedule values with no in-block uses later
When scheduling a block, deprioritize values whose results aren't used until subsequent blocks. For #58166, this has the effect of pushing the induction variable increment to the end of the block, past all the other uses of the pre-incremented value. Do this only with optimizations on. Debuggers have a preference for values in source code order, which this CL can degrade.

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.

cmd/compile/internal/noder: stop creating TUNION types
In the types1 universe under the unified frontend, we never need to
worry about type parameter constraints, so we only see pure
interfaces. However, we might still see interfaces that contain union
types, because of interfaces like "interface{ any | int }" (equivalent
to just "any").
We can handle these without needing to actually represent type unions
within types1 by simply mapping any union to "any".

When -m=N (where N > 1) is in effect, include a note in the trace output if a given function is considered "big" during inlining analysis, since this causes the inliner to be less aggressive. If a small change to a large function happens to nudge it over the large function threshold, it can be confusing for developers, thus it's probably worth including this info in the remark output.

Used to compile to:
temp := BLSR(x) // x&(x-1)
flags = TEST(temp, temp)
return flags.zf
However the blsr instruction already set ZF according to the result.
So we can remove the TEST instruction if we are just checking ZF.
Such as in multiple pieces of code around memory allocations.
This make the code smaller and faster.

Forward scheduling makes it easier to prioritize scheduling values as soon as they are ready, which is important for things like nil checks, select ops, etc. Forward scheduling is also quite a bit clearer.

cmd/compile: add anchored version of SP
The SPanchored opcode is identical to SP, except that it takes a memory argument so that it (and more importantly, anything that uses it) must be scheduled at or after that memory argument. This opcode ensures that a LEAQ of a variable gets scheduled after the corresponding VARDEF for that variable. This may lead to less CSE of LEAQ operations. The effect is very small. The go binary is only 80 bytes bigger after this CL. Usually LEAQs get folded into load/store operations, so the effect is only for pointerful types, large enough to need a duffzero, and have their address passed somewhere. Even then, usually the CSEd LEAQs will be un-CSEd because the two uses are on different sides of a function call and the LEAQ ends up being rematerialized at the second use anyway.

runtime: replace panic(nil) with panic(new(runtime.PanicNilError))
Long ago we decided that panic(nil) was too unlikely to bother
making a special case for purposes of recover. Unfortunately,
it has turned out not to be a special case. There are many examples
of code in the Go ecosystem where an author has written panic(nil)
because they want to panic and don't care about the panic value.
Using panic(nil) in this case has the unfortunate behavior of
making recover behave as though the goroutine isn't panicking.
As a result, code like:
func f() {
defer func() {
if err := recover(); err != nil {
log.Fatalf("panicked! %v", err)
}
}()
call1()
call2()
}
looks like it guarantees that call2 has been run any time f returns,
but that turns out not to be strictly true. If call1 does panic(nil),
then f returns "successfully", having recovered the panic, but
without calling call2.
Instead you have to write something like:
func f() {
done := false
defer func() {
if err := recover(); !done {
log.Fatalf("panicked! %v", err)
}
}()
call1()
call2()
done = true
}
which defeats nearly the whole point of recover. No one does this,
with the result that almost all uses of recover are subtly broken.
One specific broken use along these lines is in net/http, which
recovers from panics in handlers and sends back an HTTP error.
Users discovered in the early days of Go that panic(nil) was a
convenient way to jump out of a handler up to the serving loop
without sending back an HTTP error. This was a bug, not a feature.
Go 1.8 added panic(http.ErrAbortHandler) as a better way to access the feature.
Any lingering code that uses panic(nil) to abort an HTTP handler
without a failure message should be changed to use http.ErrAbortHandler.
Programs that need the old, unintended behavior from net/http
or other packages can set GODEBUG=panicnil=1 to stop the run-time error.
Uses of recover that want to detect panic(nil) in new programs
can check for recover returning a value of type *runtime.PanicNilError.
Because the new GODEBUG is used inside the runtime, we can't
import internal/godebug, so there is some new machinery to
cross-connect those in this CL, to allow a mutable GODEBUG setting.
That won't be necessary if we add any other mutable GODEBUG settings
in the future. The CL also corrects the handling of defaulted GODEBUG
values in the runtime, for #56986.
Fixes #25448.

cmd/compile: fix static init inlining for hidden node fields
Unified IR added several new IR fields for holding *runtime._type expressions. To avoid throwing off any frontend semantics (particularly inlining cost heuristics), they were marked as `mknode:"-"` so that code wouldn't visit them. Unfortunately, this has a bad interaction with the static init inlining optimization, because the latter relies on ir.EditChildren to substitute all parameters. This potentially includes dictionary parameters, which can appear within the new RType fields. This CL adds a new ir.EditChildrenWithHidden function that also edits these fields, and switches staticinit to use it. Longer term, we should unhide the RType fields so that ir.EditChildren visits them normally, but that's scarier so late in the release cycle. Fixes #57778.

go/types, types2: don't look up fields or methods when expecting a type
As we have seen many times, the type checker must be careful to avoid accessing named type information before the type is fully set up. We need a more systematic solution to this problem, but for now avoid one case that causes a crash: checking a selector expression on an incomplete type when a type expression is expected.

cmd/compile: use "satisfies" (not "implements") for constraint errors
Per the latest spec, we distinguish between interface implementation and constraint satisfaction. Use the verb "satisfy" when reporting an error about failing constraint satisfaction. This CL only changes error messages. It has no impact on correct code. Fixes #57564.

cmd/compile: desugar OCALLMETH->OCALLFUNC within devirtualization
Devirtualization can turn OCALLINTER into OCALLMETH, but then we want to actually desugar into OCALLFUNC instead for later phases. Just needs a missing call to typecheck.FixMethodCall. Fixes #57309.

cmd/compile: fix conditional select rule
ARM64 maintains booleans in the low byte of registers. Upper parts of that register are junk. This rule is using all 32 bits of a boolean-containing register, which is wrong.

cmd/compile: fix inline static init with derived types
CL 450136 added handling for simple calls in staticinit. If there's any derived types conversion in the body of generic function called, that conversion will require runtime dictionary, thus the optimization could not happen.

cmd/compile: disallow CMOV optimization with ptr arithmetic as an arg
if q != nil {
p = &q.f
}
Which gets rewritten to a conditional move:
tmp := &q.f
p = Select q!=nil, tmp, p
Unfortunately, we can't compute &q.f before we've checked if q is nil,
because if it is nil, &q.f is an invalid pointer (if f's offset is
nonzero but small).
Normally this is not a problem because the tmp variable above
immediately dies, and is thus not live across any safepoint. However,
if later there is another &q.f computation, those two computations are
CSEd, causing tmp to be used at both use points. That will extend
tmp's lifetime, possibly across a call.
Fixes #56990

cmd/compile: reenable inlstaticinit
This was disabled in CL 452676 out of an abundance of caution, but further analysis has shown that the failures were not being caused by this optimization. Instead the sequence of commits was: CL 450136 cmd/compile: handle simple inlined calls in staticinit ... CL 449937 archive/tar, archive/zip: return ErrInsecurePath for unsafe paths ... CL 451555 cmd/compile: fix static init for inlined calls The failures in question became compile failures in the first CL and started building again after the last CL. But in the interim the code had been broken by the middle CL. CL 451555 was just the first time that the tests could run and fail. For #30820.

cmd/compile: add -d=inlstaticinit debug flag
This CL adds -d=inlstaticinit to control whether static initialization of inlined function calls (added in CL 450136) is allowed. We've needed to fix it once already (CL 451555) and Google-internal testing is hitting additional failure cases, so putting this optimization behind a feature flag seems appropriate regardless. Also, while we diagnose and fix the remaining cases, this CL also disables the optimization to avoid miscompilations. Updates #56894.
