9f9dd2bfd8 cmd/compile: fix cmpstring rewrite rule
We need to ensure that the Select0 lives in the same block as
its argument. Divide up the rule into 2 so that we can put the
parts in the right places.

(This would be simpler if we could use @block syntax mid-rule, but
that feature currently only works at the top level.)

This fixes the ssacheck builder after CL 578835

79065f0a5e net/netip: use the unique package instead of internal/intern
This change replaces net/netip's use of the internal/intern package with
the new unique package.

Below are the benchmark results for the package. Lots of things get
faster, but some things get slower. The single-core performance of
unique.Make is expected to be a tad slower than internal/intern, but is
vastly more scalable. No benchmark in this package currently
demonstrates this, however.

4bb67bc21e runtime: always acquire M when acquiring locks by rank
Profiling of runtime-internal locks checks gp.m.locks to see if it's
safe to add a new record to the profile, but direct use of
acquireLockRank can change the list of the M's active lock ranks without
updating gp.m.locks to match. The runtime's internal rwmutex
implementation makes a point of calling acquirem/releasem when
manipulating the lock rank list, but the other user of acquireLockRank
(the GC's Gscan bit) relied on the GC's invariants to avoid deadlocks.

Codify the rwmutex approach by renaming acquireLockRank to
acquireLockRankAndM and having it include a call to aquirem. Do the same
for release.

Fixes #64706
Fixes #66004

2dddc7ef88 cmd/link: move .dynamic and .got sections to relro if applicable
This is the second of two CLs to roll forward the changes in CL
473495, which was subsequently reverted.

In this patch we move the .dynamic and .got sections from the writable
data segment to the relro segment if the platform supports relro and
we're producing a PIE binary, and also moves .got.plt into relro if
eager binding is in effect (e.g. -bindnow or -Wl,-z,now).

Updates #45681.

Suggested by me here in 2021:
https://go-review.googlesource.com/c/go/+/280372/comment/1a86b8aa_f64310bf/
Never got around to it until now.

ef2f3391da runtime: make it harder to find collisions in the 64-bit fallback hash
Currently the first argument to mix() can be set by an attacker, as it
is just the input bytes xored by some constants. That lets an attacker
set the value being multipled by to 0. That can lead to lots of
collisions. To fix, xor the first argument with the process-wide seed,
so the magic collision-generating value isn't a constant known to the
attacker.  (Maybe there's a timing attack that could figure out the
process-wide seed, but that's a much harder attack.)

Fixes #66841

2b82a4f488 runtime: track frame pointer while in syscall
Currently the runtime only tracks the PC and SP upon entering a syscall,
but not the FP (BP). This is mainly for historical reasons, and because
the tracer (which uses the frame pointer unwinder) does not need it.

Until it did, of course, in CL 567076, where the tracer tries to take a
stack trace of a goroutine that's in a syscall from afar. It tries to
use gp.sched.bp and lots of things go wrong. It *really* should be using
the equivalent of gp.syscallbp, which doesn't exist before this CL.

This change introduces gp.syscallbp and tracks it. It also introduces
getcallerfp which is nice for simplifying some code. Because we now have
gp.syscallbp, we can also delete the frame skip count computation in
traceLocker.GoSysCall, because it's now the same regardless of whether
frame pointer unwinding is used.

Fixes #66889.

dcb5de5cac cmd/trace/v2: tolerate traces with broken tails
This change modifies cmd/trace/v2 to tolerate traces with
incomplete/broken generations at the tail. These broken tails can be
created if a program crashes while a trace is being produced. Although
the runtime tries to flush the trace on some panics, it may still
produce some extra trace data that is incomplete.

This change modifies cmd/trace/v2 to still work on any complete
generations, even if there are incomplete/broken generations at the tail
end of the trace. Basically, the tool now just tracks when the last good
generation ended (via Sync events) and truncates the trace to that point
when it encounters an error.

This change also revamps the text output of the tool to emit regular
progress notifications as well as warnings as to how much of the trace
data was lost.

Fixes #65316.

4324d5a88c internal/concurrent: handle boundary case for hash bits in HashTrieMap
Currently the HashTrieMap has a panic for running out of hash bits, but
it turns out we can end up in these paths in valid cases, like inserting
or deleting an element that requires *all* the hash bits to finds its
position in the tree. There's basically an off-by-one error here where
the panic fires erroneously.

This wasn't caught before the original CL landed because it's very
unlikely on 64-bit platforms, with a 64-bit hash, but much more likely
on 32-bit platforms, where using all 32 bits of a 32-bit hash is much
more likely.

This CL makes the condition for panicking much more explicit, which
avoids the off-by-one error.

After this CL, I can't get the tests to fail on 32-bit under stress
testing.

104c293ffe syscall/js: allocate arg slices on stack for small numbers of args
The existing implementation causes unnecessary heap allocations for
javascript syscalls: Call, Invoke, and New. The new change seeks to
hint the Go compiler to allocate arg slices with length <=16 to the
stack.

Original Work: CL 367045
- Calling a JavaScript function with 16 arguments or fewer will not
induce two additional heap allocations, at least with the current Go
compiler.
- Using syscall/js features with slices and strings of
statically-known length will not cause them to be escaped to the heap,
at least with the current Go compiler.
- The reduction in allocations has the additional benefit that the
garbage collector runs less often, blocking WebAssembly's one and only
thread less often.

fa470f6245 internal/concurrent: add HashTrieMap
This change adds a concurrent hash-trie map implementation to the
standard library in the new internal/concurrent package, intended to
hold concurrent data structures. (The name comes from how Java names
their concurrent data structure library in the standard library.)

This data structure is created specially for the upcoming unique
package. It is built specifically around frequent successful lookups and
comparatively rare insertions and deletions.

A valid question is whether this is worth it over a simple locked map.
Some microbenchmarks in this new package show that yes, this extra
complexity appears to be worth it.

Single-threaded performance for LoadOrStore is comparable to a locked
map for a map with 128k small string elements. The map scales perfectly
up to 24 cores for Loads, which is the maximum available parallelism
on my machine. LoadOrStore operations scale less well. Small maps will
have a high degree of contention, but for the unique library, small maps
are very unlikely to stay small if there are a lot of inserts, since
they have a full GC cycle to grow.

For #62483.

e01b1eb289 cmd/compile/internal: stack slot merging region formation enhancements
This patch revises the algorithm/strategy used for overlapping the
stack slots of disjointly accessed local variables. The main change
here is to allow merging the stack slot of B into the slot for A if
B's size is less then A (prior to this they had to be identical), and
to also allow merging a non-pointer variables into pointer-variable
slots.

The new algorithm sorts the candidate list first by pointerness
(pointer variables first), then by alignment, then by size, and
finally by name. We no longer check that two variables have the same
GC shape before merging: since it should never be the case that we
have two vars X and Y both live across a given callsite where X and Y
share a stack slot, their gc shape doesn't matter.

Doing things this new way increases the total number of bytes saved
(across all functions) from 91256 to 124336 for the sweet benchmarks.

Updates #62737.
Updates #65532.
Updates #65495.

a973b4256e cmd/dist: allow arbitrary package renames for bootstrap imports
Import declaration matching currently has a list of specific cases. It
allows bare imports, dot imports, and renamed imports named "exec" and
"rtabi".

Keeping a specific allowlist of renamed imports is unnecessary and
causes annoyance for developers adding such imports, as the bootstrap
build errors do not make it clear that this is where the issue lies.

We can simplify this to be much more general. The body of the condition
will still only rewrite imports in cmd/ or in bootstrapDirs.

I believe the only downside of this change is that it makes it a bit
more likely to match and replace within comments. That said, there
should be no harm in replacements within comments.

This change results in no change to the resulting bootstrap source tree:

84fbdf01ff cmd/go: use cache for PGO preprocessing
This is the final CL in the series adding PGO preprocessing support to
cmd/go. Now that the tool is hooked up, we integrate with the build
cache to cache the result.

This is fairly straightforward. One difference is that the compile and
link do caching through updateBuildID. However, preprocessed PGO files
don't have a build ID, so it doesn't make much sense to hack our way
through that function when it is simple to just add to the cache
ourselves.

As as aside, we could add a build ID to the preproccessed file format,
though it is not clear if it is worthwhile. The one place a build ID
could be used is in buildActionID, which currently compute the file hash
of the preprocessed profile. With a build ID it could simply read the
build ID. This would save one complete read of the file per build
(cmd/go caches the hash), but each compile process also reads the entire
file, so this is a small change overall.

Fixes #58102.

4084bc1aa2 cmd/go: inital plumbing for PGO profiles preprocessing
The new go tool preprofile preprocesses a PGO pprof profile into an
intermediate representation that is more efficient for the compiler to
consume. Performing preprocessing avoids having every single compile
process from duplicating the same processing.

This CL prepares the initial plumbing to support automatic preprocessing
by cmd/go.

Each compile action takes a new dependency on a new "preprocess PGO
profile" action. The same action instance is shared by all compile
actions (assuming they have the same input profile), so the action only
executes once.

Builder.build retrieves the file to pass to -pgofile from the output of
the preprocessing action, rather than directly from
p.Internal.PGOProfile.

Builder.buildActionID also uses the preprocess output as the PGO
component of the cache key, rather than the original source. This
doesn't matter for normal toolchain releases, as the two files are
semantically equivalent, but it is useful for correct cache invalidation
in development. For example, if _only_ go tool preprofile changes
(potentially changing the output), then we must regenerate the output
and then rebuild all packages.

This CL does not actually invoke go tool preprocess. That will come in
the next CL. For now, it just copies the input pprof profile.

This CL shouldn't be submitted on its own, only with the children. Since
the new action doesn't yet use the build cache, every build (even fully
cached builds) unconditionally run the PGO action.

For #58102.

9101bf1916 go/types, types2: use types2.Config flag to control Alias node creation
Move Checker.enableAlias to Config.EnableAlias (for types2) and
Config._EnableAlias (for go/types), and adjust all uses.

Use Config.EnableAlias to control Alias creation for types2 and
with that remove dependencies on the gotypesalias GODEBUG setting
and problems during bootstrap. The only client is the compiler and
there we simply use the desired configuration; it is undesirable
for the compiler to be dependent on gotypesalias.

Use the gotypesalias GODEBUG setting to control Config._EnableAlias
for go/types (similar to before).

Adjust some related code. We plan to remove gotypesalias eventually
which will remove some of the new discrepancies between types2 and
go/types again.

Fixes #66874.

334ce51004 net/http: don't cancel Dials when requests are canceled
Currently, when a Transport creates a new connection for a request,
it uses the request's Context to make the Dial. If a request
times out or is canceled before a Dial completes, the Dial is
canceled.

Change this so that the lifetime of a Dial call is not bound
by the request that originated it.

This change avoids a scenario where a Transport can start and
then cancel many Dial calls in rapid succession:

  - Request starts a Dial.
  - A previous request completes, making its connection available.
  - The new request uses the now-idle connection, and completes.
  - The request Context is canceled, and the Dial is aborted.

Fixes #59017

4742c52e10 internal/abi: define EmptyInterface, TypeOf, and NoEscape
This change defines two commonly-defined functions and a
commonly-defined type in internal/abi to try and deduplicate some
definitions. This is motivated by a follow-up CL which will want access
to TypeOf in yet another package.

There still exist duplicate definitions of all three of these things in
the runtime, and this CL doesn't try to handle that yet. There are far
too many uses in the runtime to handle manually in a way that feels
comfortable; automated refactoring will help.

For #62483.

2073b35e07 crypto/tls: add a bogo shim
Run the BoGo test suite.

For now a number of tests are disabled, so that we can land the shim.
Once the shim is in the tree I'll work on fixing tests, and aligning
the TLS stack with the boringssl stack.

Eventually we should also remove the --loose-errors flag.

Fixes #51434

c686783cab cmd/compile/internal/ssa: delay rewrite cycle detection for huge funcs
The SSA rewrite pass has some logic that looks to see whether a
suspiciously large number of rewrites is happening, and if so, turns
on logic to try to detect rewrite cycles. The cycle detection logic is
quite expensive (hashes the entire function), meaning that for very
large functions we might get a successful compilation in a minute or
two with no cycle detection, but take a couple of hours once cycle
detection kicks in.

This patch moves from a fixed limit of 1000 iterations to a limit set
partially based on the size of the function (meaning that we'll wait
longer before turning cycle detection for a large func).

Fixes #66773.
