da5d8fdd0c runtime: run wasip1 tests with wazero
The latest wazero release supports non-blocking I/O and pre-opened
sockets. Unmask the relevant wasip1 tests so that there are multiple
WebAssembly runtimes exercising these code paths.

411c99671a slices, maps: add examples; doc comment fixes
There are currently no examples in the new slices and maps package, so
add some. This adds examples for most functions in the slices package
except the very obvious ones, and adds examples for the DeleteFunc and
EqualFunc functions in the maps package.

Also clarify/correct a few doc comments:

* EqualFunc takes an "equality" function, not a "comparison" function
* It's confusing for Delete and DeleteFunc to say they "do not create a
  new slice", as they do return a new slice. They already say they
  "return the modified slice" which is enough.
* Similar for Compact, and mention that it returns the modified slice
  (and say why)
* Note that CompactFunc keeps the first element in equal runs
* Say what cmp is in SortStableFunc and IsSortedFunc
* Say that MinFunc and MaxFunc return the first value

03cd8a7b0e internal/bytealg: fix alignment code in equal_riscv64.s
The riscv64 implementation of equal has an optimization that is
applied when both pointers share the same alignment but that alignment
is not 8 bytes.  In this case it tries to align both pointers to an 8 byte boundaries,
by individually comparing the first few bytes of each buffer.  Unfortunately,
the existing code is incorrect.  It adjusts the pointers by the wrong number
of bytes resulting, in most cases, in pointers that are not 8 byte aligned.

This commit fixes the issue by individually comparing the first
(8 - (pointer & 7)) bytes of each buffer rather than the first
(pointer & 7) bytes.

This particular optimization is not covered by any of the existing
benchmarks so a new benchmark, BenchmarkEqualBothUnaligned,
is provided.  The benchmark tests the case where both pointers have
the same alignment but may not be 8 byte aligned.  Results of the
new benchmark along with some of the existing benchmarks generated on
a SiFive HiFive Unmatched A00 with 16GB of RAM running Ubuntu 23.04
are presented below.

8b5fe5980c cmd/compile: handle min/max correctly in mayCall
CL 500575 changed mayCall to return "false" for min/max builtin.

However, with string or float, min/max requires runtime call, so mayCall
should return true instead. This's probably not a big problem, because
CL 506115 makes order pass handle min/max correctly. But it's still
better to do it the right way.

Updates #60582

79d4defa75 cmd/compile/internal/ssagen: fix min/max codegen, again
The large-function phi placement algorithm evidently doesn't like the
same pseudo-variable being used to represent expressions of varying
types.

Instead, use the same tactic as used for "valVar" (ssa.go:6585--6587),
which is to just generate a fresh marker node each time.

Maybe we could just use the OMIN/OMAX nodes themselves as the key
(like we do for OANDAND/OOROR), but that just seems needlessly risky
for negligible memory savings. Using fresh marker values each time
seems obviously safe by comparison.

Fixes #61041.

6691f438c3 cmd/dist, internal/abi: support bootstrapping with gccgo
The required gc bootstrap compiler, 1.17, has an internal/lazyregexp
package. It permits that package to be imported by internal/profile
while bootstrapping. The gccgo compiler also has an internal/lazyregexp
package, but it does not permit the gc compiler to import it.

Permit bootstrapping with gccgo by adding internal/lazyregexp to the
list of bootstrap directories.

The gccgo compiler recognizes the magic functions internal/abi.FuncPCABI0
and FuncPCABIInternal, but only in the internal/abi package, not
in the bootstrapping internal/abi package.

Permit bootstrapping with gccgo by adding definitions of those functions
with build tags so that they are only used by gccgo.

4f36f7e4dd encoding: document that base32 and base64 do not use UTF-8
The invention of base32 and base64 predates the invention of UTF-8
and was never meant to output valid UTF-8.
By default, the output is always valid ASCII (and thus valid UTF-8)
except when the user specifies an alphabet or padding value
that is larger than '\x7f'. If that is done,
then the exact byte symbol is used rather than the UTF-8 encoding.

but doesn't change it, even if the runtime supports non-blocking
stdio. Since WebAssembly modules are single-threaded, blocking
system calls temporarily halt execution of the module. If the
runtime supports non-blocking stdio, the Go runtime is able to
use the WASI net poller to poll for read/write readiness and is
able to schedule goroutines while waiting.

d49017a7c3 go/types, types2: fix interface unification
When unification of two types succeeds and at least one of them
is an interface, we must be more cautious about when to accept
the unification, to avoid order dependencies and unexpected
inference results.

The changes are localized and only affect matching against
interfaces; they further restrict what are valid unifications
(rather than allowing more code to pass). We may be able to
remove some of the restriotions in a future release.

See comments in code for a detailed description of the changes.

Also, factored out "asInterface" functionality into a function
to avoid needless repetition in the code.

Fixes #60933.
Fixes #60946.

a031f4ef83 cmd/compile: fix min/max builtin code generation
Our large-function phi placement algorithm is incompatible with phi
opcodes already existing in the SSA representation. Instead, use simple
variable assignments and have the phi placement algorithm place the phis
we need for min/max.

Turns out the small-function phi placement algorithm doesn't have this
sensitivity, so this bug only occurs in large functions (>500 basic blocks).

Maybe we should document/check that no phis are present when we start
phi placement (regardless of size).  Leaving for a potential separate CL.

We should probably also fix the placement algorithm to handle existing
phis correctly.  But this CL is probably a lot smaller/safer than
messing with phi placement.

Fixes #60982

48dbb6227a runtime: set raceignore to zero when starting a new goroutine
When reusing a g struct the runtime did not reset
g.raceignore. Initialize raceignore to zero when initially
setting racectx.

A goroutine can end with a non-zero raceignore if it exits
after calling runtime.RaceDisable without a matching
runtime.RaceEnable. If that goroutine's g is later reused
the race detector is in a weird state: the underlying
g.racectx is active, yet g.raceignore is non-zero, and
raceacquire/racerelease which check g.raceignore become
no-ops. This causes the race detector to report races when
there are none.

that have the same subject (but different SPKIs) at the asme time. As

Rather than doing something fancy to include keys (which is just overly
complicated), tolerate multiple matches.

a7b1793701 cmd/go: do not index std as a module in modcache
We do not index std as a whole module ever.

When working in the main Go repo, files in package change often,
so we don't want to pay the cost of reindexing all of std when what
we really need is just to reindex strings. Per-package indexing
works better for that case.

When using a released Go toolchain, we don't have to worry about
the whole module changing, but if we switch to whole-module indexing
at that point, we have the potential for bugs that only happen in
released toolchains. Probably not worth the risk.

For similar reasons, we don't index the current work module as
a whole module (individual packages are changing), so we use the heuristic
that we only do whole-module indexing in the module cache.

The new toolchain modules live in the module cache, though, and
our heuristic was causing whole-module indexing for them.
As predicted, enabling whole-module indexing for std when it's
completely untested does in fact lead to bugs (a very minor one).

This CL turns off whole-module indexing for std even when it is
in the module cache, to bring toolchain module behavior back in
line with the other ways to run toolchains.

For #57001.
