Keith Randall 61bc17f04e cmd/compile: don't assume pointer of a slice is non-nil
unsafe.SliceData can return pointers which are nil. That function gets
lowered to the SSA OpSlicePtr, which the compiler assumes is non-nil.
This used to be the case as OpSlicePtr was only used in situations
where the bounds check already passed. But with unsafe.SliceData that
is no longer the case.

There are situations where we know it is nil. Use Bounded() to
indicate that.

I looked through all the uses of OSPTR and added SetBounded where it
made sense. Most OSPTR results are passed directly to runtime calls
(e.g. memmove), so even if we know they are non-nil that info isn't
helpful.

Fixes #59293

Robert Griesemer 8c5e8a38df go/types, types2: refactor initVars
As with changes in prior CLs, we don't suppress legitimate
"declared but not used" errors anymore simply because the
respective variables are used in incorrect assignments,
unrelated to the variables in question.
Adjust several (ancient) tests accordingly.

Robert Griesemer abf9b112fd go/types, types2: more systematic use of Checker.use und useLHS
This CL re-introduces useLHS because we don't want to suppress
correct "declared but not used" errors for variables that only
appear on the LHS of an assignment (using Checker.use would mark
them as used).

This CL also adjusts a couple of places where types2 differed
from go/types (and suppressed valid "declared and not used"
errors). Now those errors are surfaced. Adjusted a handful of
tests accordingly.

In the Sizes API, recognize an overflow (to a negative value) as a
consequence of an oversize value, and specify as such in the API.

Adjust the various size computations to take overflow into account.

Recognize a negative size or offset as an error and report it rather
than panicking.

Use the same protocol for results provided by the default (StdSizes)
and external Sizes implementations.

erifan01 42f99b203d cmd/compile: optimize cmp to cmn under conditions < and >= on arm64
Under the right conditions we can optimize cmp comparisons to cmn
comparisons, such as:
func foo(a, b int) int {
  var c int
  if a + b < 0 {
  	c = 1
  }
  return c
}

Previously it's compiled as:
  ADD     R1, R0, R1
  CMP     $0, R1
  CSET    LT, R0
With this CL it's compiled as:
  CMN     R1, R0
  CSET    MI, R0
Here we need to pay attention to the overflow situation of a+b, the MI
flag means N==1, which doesn't honor the overflow flag V, its value
depends only on the sign of the result. So it has the same semantic of
the Go code, so it's correct.

Similarly, this CL also optimizes the case of >= comparison
using the PL conditional flag.

erifan01 91a2e921dd cmd/compile: fix incorrect truncating when converting CMP to TST on arm64
CL 420434 optimized CMP into TST in some situations, but it has a bug,
these four rules are not correct:
(LessThan (CMPWconst [0] x:(ANDconst [c] y))) && x.Uses == 1 => (LessThan (TSTconst [c] y))
(LessEqual (CMPWconst [0] x:(ANDconst [c] y))) && x.Uses == 1 => (LessEqual (TSTconst [c] y))

(GreaterEqual (CMPWconst [0] x:(ANDconst [c] y))) && x.Uses == 1 => (GreaterEqual (TSTconst [c] y))

But due to the existence of this rule
(LessThan (CMPWconst [0] x:(ANDconst [c] y))) && x.Uses == 1 =>
(LessThan (TSTWconst [int32(c)] y)), the above rules have never been

Than McIntosh f5c7416511 cmd/compile: reorder operations in SCCs to enable more inlining
This patch changes the relative order of "CanInline" and "InlineCalls"
operations within the inliner for clumps of functions corresponding to
strongly connected components in the call graph. This helps increase
the amount of inlining within SCCs, particularly in Go's runtime
package, which has a couple of very large SCCs.

For a given SCC of the form { fn1, fn2, ... fnk }, the inliner would
(prior to this point) walk through the list of functions and for each
function first compute inlinability ("CanInline") and then perform
inlining ("InlineCalls"). This meant that if there was an inlinable
call from fn3 to fn4 (for example), this call would never be inlined,
since at the point fn3 was visited, we would not have computed
inlinability for fn4.

We now do inlinability analysis for all functions in an SCC first,
then do actual inlining for everything. This results in 47 additional
inlines in the Go runtime package (a fairly modest increase
percentage-wise of 0.6%).

Updates #58905.

Cherry Mui b675a75c3d cmd/compile: enable address folding for globals on ARM64, just not -dynlink mode
On ARM64, in -dynlink mode (building a shared library or a plugin),
accessing global variable is made using the GOT. Currently, the
GOT accessing instruction sequence our assembler generates doesn't
handle large offset well, so we don't fold the offset into loads
and stores in the compiler. Currently, the rewrite rules are
guarded with the -shared flag. However, the GOT access
instructions are only generated in the -dynlink mode (which
implies -shared, but not the other direction).

CL 445535 attempted to remove the guard althgether. But that
causes build failure for -dynlink mode for the reason above. This
CL changes it to guard specifically on -dynlink mode, allowing
the optimization in more cases (-shared but not -dynlink build
modes).

Updates #58826.

David Chase c20d959163 cmd/compile: experimental loop iterator capture semantics change
Adds:
GOEXPERIMENT=loopvar (expected way of invoking)
-d=loopvar={-1,0,1,2,11,12} (for per-package control and/or logging)
-d=loopvarhash=... (for hash debugging)

loopvar=11,12 are for testing, benchmarking, and debugging.

If enabled,for loops of the form `for x,y := range thing`, if x and/or
y are addressed or captured by a closure, are transformed by renaming
x/y to a temporary and prepending an assignment to the body of the
loop x := tmp_x.  This changes the loop semantics by making each
iteration's instance of x be distinct from the others (currently they
are all aliased, and when this matters, it is almost always a bug).

3-range with captured iteration variables are also transformed,
though it is a more complex transformation.

"Optimized" to do a simpler transformation for
3-clause for where the increment is empty.

(Prior optimization of address-taking under Return disabled, because
it was incorrect; returns can have loops for children.  Restored in
a later CL.)

Includes support for -d=loopvarhash=<binary string> intended for use
with hash search and GOCOMPILEDEBUG=loopvarhash=<binary string>
(use `gossahash -e loopvarhash command-that-fails`).

Minor feature upgrades to hash-triggered features; clients can specify
that file-position hashes use only the most-inline position, and/or that
they use only the basenames of source files (not the full directory path).
Most-inlined is the right choice for debugging loop-iteration change
once the semantics are linked to the package across inlining; basename-only
makes it tractable to write tests (which, otherwise, depend on the full
pathname of the source file and thus vary).

Updates #57969.

Dmitri Shuralyov 7a0799b2c0 cmd/dist, test: convert test/run.go runner to a cmd/go test
As motivated on the issue, we want to move the functionality of the
run.go program to happen via a normal go test. Each .go test case in
the GOROOT/test directory gets a subtest, and cmd/go's support for
parallel test execution replaces run.go's own implementation thereof.

The goal of this change is to have fairly minimal and readable diff
while making an atomic changeover. The working directory is modified
during the test execution to be GOROOT/test as it was with run.go,
and most of the test struct and its run method are kept unchanged.
The next CL in the stack applies further simplifications and cleanups
that become viable.

There's no noticeable difference in test execution time: it takes around
60-80 seconds both before and after on my machine. Test caching, which
the previous runner lacked, can shorten the time significantly.

Matthew Dempsky fa9efd9171 cmd/compile/internal/noder: correct positions for synthetic closures
When inlining functions that contain function literals, we need to be
careful about position information. The OCLOSURE node should use the
inline-adjusted position, but the ODCLFUNC and its body should use the
original positions.

However, the same problem can arise with certain generic constructs,
which require the compiler to synthesize function literals to insert
dictionary arguments.

go.dev/cl/425395 fixed the issue with user-written function literals
in a somewhat kludgy way; this CL extends the same solution to
synthetic function literals.

This is all quite subtle and the solutions aren't terribly robust, so
longer term it's probably desirable to revisit how we track inlining
context for positions. But for now, this seems to be the least bad
solution, esp. for backporting to 1.20.

Updates #54625.
Fixes #58513.

with 0. For example, x < 1 is equivalent to x <= 0. This is an
advantageous transformation on riscv64 because comparisons with zero
do not require a constant to be loaded into a register. Other
architectures will likely benefit too and the transformation is
relatively benign on architectures that do not benefit.

Lynn Boger ebe49f98c8 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.

Cuong Manh Le 93f10b8829 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.

Cuong Manh Le abd55d8483 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.

Fixes #58325

Keith Randall 103f37497f 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.

This CL adds rules that replaces instances of ISEL that produce
a boolean result based on a condition register by 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

Jakub Ciolek 1fc585dc2f 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.

Keith Randall 1e12c63aac 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.

Fixes #54159

Paul E. Murphy 1540531746 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).

Paul E. Murphy 0301c6c351 test/codegen: combine trivial PPC64 tests into ppc64x
Use a small python script to consolidate duplicate

This makes small assumption that anytime two tests with

can be combined into a single ppc64x test.

Matthew Dempsky a7de684e1b 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".

Updates #57410.

Paul E. Murphy a37672bb7b test/codegen: accept ppc64x as alias for ppc64le and ppc64 arches
This helps simplify the noise when adding ppc codegen tests. ppc64x
is used in other places to indicate something which runs on either
endian.

This helps cleanup existing codegen tests which are mostly
identical between endian variants.

condmove tests are converted as an example.

Than McIntosh 733ba92187 cmd/compile: flag 'large' functions when -m=2+ in effect
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.
