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. Fixes #58166 Fixes #57976 Change-Id: I40d5885c661b142443c6d4702294c8abe8026c4f Reviewed-on: https://go-review.googlesource.com/c/go/+/463751 Run-TryBot: Keith Randall <khr@golang.org> Reviewed-by: David Chase <drchase@google.com> Reviewed-by: Keith Randall <khr@google.com> TryBot-Result: Gopher Robot <gobot@golang.org> |

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: 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.

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.

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.

If OpArgIntReg is incorrectly scheduled, that causes it to be spilled incorrectly, which causes the argument to not be considered live at the start of the function.

cmd/compile: AMD64v3 remove unnecessary TEST comparision in isPowerOfTwo
With GOAMD64=V3 the canonical isPowerOfTwo function:
func isPowerOfTwo(x uintptr) bool {
return x&(x-1) == 0
}
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.

cmd/compile: improve scheduling pass
Convert the scheduling pass from scheduling backwards to scheduling forwards. 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. It was originally backwards because computing uses is tricky, but I found a way to do it simply and with n lg n complexity. The new scheme also makes it easy to add new scheduling edges if needed.

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.

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.

test: fix noinit on noopt builder
Fix noopt build break from CL 450136 by not running test. I can't reproduce the failure locally, but it's entirely reasonable for this test to fail when optimizations are disabled, so just don't run it when optimizations are disabled.

cmd/compile: handle simple inlined calls in staticinit
Global variable initializers like
var myErr error = &myError{"msg"}
have been converted to statically initialized data
from the earliest days of Go: there is no init-time
execution or allocation for that line of code.
But if the expression is moved into an inlinable function,
the static initialization no longer happens.
That is, this code has always executed and allocated
at init time, even after we added inlining to the compiler,
which should in theory make this code equivalent to
the original:
func NewError(s string) error { return &myError{s} }
var myErr2 = NewError("msg")
This CL makes the static initialization rewriter understand
inlined functions consisting of a single return statement,
like in this example, so that myErr2 can be implemented as
statically initialized data too, just like myErr, with no init-time
execution or allocation.
A real example of code that benefits from this rewrite is
all globally declared errors created with errors.New, like
package io
var EOF = errors.New("EOF")
Package io no longer has to allocate and initialize EOF each
time a program starts.
Another example of code that benefits is any globally declared
godebug setting (using the API from CL 449504), like
package http
var http2server = godebug.New("http2server")
These are no longer allocated and initialized at program startup either.
The list of functions that are inlined into static initializers when
compiling std and cmd (along with how many times each occurs) is:
cmd/compile/internal/ssa.StringToAux (3)
cmd/compile/internal/walk.mkmapnames (4)
errors.New (360)
go/ast.NewIdent (1)
go/constant.MakeBool (4)
go/constant.MakeInt64 (3)
image.NewUniform (4)
image/color.ModelFunc (11)
internal/godebug.New (12)
vendor/golang.org/x/text/unicode/bidi.newBidiTrie (1)
vendor/golang.org/x/text/unicode/norm.newNfcTrie (1)
vendor/golang.org/x/text/unicode/norm.newNfkcTrie (1)
For the cmd/go binary, this CL cuts the number of init-time
allocations from about 1920 to about 1620 (a 15% reduction).
The total executable code footprint of init functions is reduced
by 24kB, from 137kB to 113kB (an 18% reduction).
The overall binary size is reduced by 45kB,
from 15.335MB to 15.290MB (a 0.3% reduction).
(The binary size savings is larger than the executable code savings
because every byte of executable code also requires corresponding
runtime tables for unwinding, source-line mapping, and so on.)
Also merge test/sinit_run.go, which had stopped testing anything
at all as of CL 161337 (Feb 2019) and initempty.go into a new test
noinit.go.
Fixes #30820.

cmd/compile: fix missing typecheck for static initialization slice
CL 440455 fixed missing walk pass for static initialization slice. However, slicelit may produce un-typechecked node, thus we need to do typecheck for sinit before calling walkStmtList.

cmd/compile: merge zero constant ISEL in PPC64 lateLower pass
Add a new SSA opcode ISELZ, similar to ISELB to represent a select of value or 0. Then, merge candidate ISEL opcodes inside the late lower pass. This avoids complicating rules within the the lower pass.

cmd/compile: fix transitive inlining of generic functions
If an imported, non-generic function F transitively calls a generic function G[T], we may need to call CanInline on G[T]. While here, we can also take advantage of the fact that we know G[T] was already seen and compiled in an imported package, so we don't need to call InlineCalls or add it to typecheck.Target.Decls. This saves us from wasting compile time re-creating DUPOK symbols that we know already exist in the imported package's link objects. Fixes #56280.
