b3bc8620f8 cmd/compile: use correct type for byteswaps on multi-byte stores
Use the type of the store for the byteswap, not the type of the
store's value argument.

Normally when we're storing a 16-bit value, the value being stored is
also typed as 16 bits. But sometimes it is typed as something smaller,
usually because it is the result of an upcast from a smaller value,
and that upcast needs no instructions.

If the type of the store's arg is thinner than the type being stored,
and the byteswap'd value uses that thinner type, and the byteswap'd
value needs to be spilled & restored, that spill/restore happens using
the thinner type, which causes us to lose some of the top bits of the
value.

Fixes #59367

42866e566a cmd/compile: minor cleanup to HashDebugPos
HashDebugPos function/method included a parameter that was always
the same, and a variable in the same package as the hashdebug code.
So remove it.

(I wrote that code, there was no reason for it to be that way).

Also corrects a stale comment in the loopvar code.

46a49eb52e cmd/internal/objfile: align the load address of ELF binary
The ELF ABI just requires that the address and the offset of a
segment are congruent modulo the alignment, but does not require
the start address to be aligned. While usually the segment's
start address is aligned, apparently the zig linker generates
binary with unaligned address.

At the run time, the memory mapping that contains the segment
starts at an aligned address (rounding down). Use the aligned
address for the load address, which matches the mapping.
Apparently this is what the pprof library expects.

Fixes #59466.

0d3c23fe87 cmd/link: bump loong64 function alignment to 16 bytes
The loong64 PCALIGN directive works with PCs relative to beginning of
functions. So if the function alignment is less than that requested by
PCALIGN, the following code may in fact not be aligned as such, leading
to unexpected performance.

The current function alignment on loong64 is 8 bytes, which seems to
stem from mips64 or riscv64. In order to make performance more
predictable on loong64, it is raised to 16 bytes to ensure that at
least `PCALIGN $16` works.

As alignment of loops written in Go is yet to be tackled, and the
codegen is not otherwise touched, benchmark numbers for this change are
not going to be meaningful, and not included.

157999f512 internal/bytealg, runtime: align some loong64 asm loops to 16-byte boundaries
The LA464 micro-architecture is very sensitive to alignment of loops,
so the final performance of linked binaries can vary wildly due to
uncontrolled alignment of certain performance-critical loops. Now that
PCALIGN is available on loong64, let's make use of it and manually align
some assembly loops. The functions are identified based on perf records
of some easily regressed go1 benchmark cases (e.g. FmtFprintfPrefixedInt,
RegexpMatchEasy0_1K and Revcomp are particularly sensitive; even those
optimizations purely reducing dynamic instruction counts can regress
those cases by 6~12%, making the numbers almost useless).

Benchmark results on Loongson 3A5000 (which is an LA464 implementation):

47b22b6548 cmd/link, cmd/internal/obj/loong64: support the PCALIGN directive
Allow writing `PCALIGN $imm` where imm is a power-of-2 between 8 and
2048 (inclusive), for ensuring that the following instruction is
placed at an imm-byte boundary relative to the beginning of the
function. If the PC is not sufficiently aligned, NOOPs will be
inserted to make it so, otherwise the directive will do nothing.

This could be useful for both asm performance hand-tuning, and future
scenarios where a certain bigger alignment might be required.

10c079a0ad encoding/xml: use reflect.Value.Grow
Like https://go.dev/cl/481376 did for encoding/gob,
but now for encoding/xml, which had very similar code.

One minor difference is that encoding/xml now needs a SetLen before the
call to Index, as otherwise we index just past the length.
Still, calling Grow and SetLen is easier to understand,
and avoids needing to make a new zero value.

Instead / for-now, remove the offending rewrite rules.

1444c0b01e net/http: wait forever for write results in tests
After performing a round trip on a connection, the connection is
usually returned to the idle connection pool. If the write of the
request did not complete successfully, the connection is not
returned.

It is possible for the response to be read before the write
goroutine has finished signalling that its write has completed.
To allow for this, the check to see if the write completed successfully
waits for 50ms for the write goroutine to report the result of the
write.

See comments in persistConn.wroteRequest for more details.

On a slow builder, it is possible for the write goroutine to take
longer than 50ms to report the status of its write, leading to test
flakiness when successive requests unexpectedly use different connections.

Set the timeout for waiting for the writer to an effectively
infinite duration in tests.

38dadcc3b5 net/http: fix a race in TestResponseControllerSetPastReadDeadline
If the Write goroutine is delayed for long enough after its first
Write, the handler may have closed both the readc and donec channels
by the time it selects over them, and the donec case may be randomly
chosen. Handle that case by explicitly checking readc as well.

This fixes a race accidentally introduced in CL 482935 and observed in
https://build.golang.org/log/fa684750994d1fda409722f144b90c65b4c52cf9.

For #59447.

39986d28e4 cmd/compile: allow more inlining of functions that construct closures
[This is a roll-forward of CL 479095, which was reverted due to a bad
interaction between inlining and escape analysis since fixed in CL 482355.]

Currently, when the inliner is determining if a function is
inlineable, it descends into the bodies of closures constructed by
that function. This has several unfortunate consequences:

- If the closure contains a disallowed operation (e.g., a defer), then
  the outer function can't be inlined. It makes sense that the
  *closure* can't be inlined in this case, but it doesn't make sense
  to punish the function that constructs the closure.

- The hairiness of the closure counts against the inlining budget of
  the outer function. Since we currently copy the closure body when
  inlining the outer function, this makes sense from the perspective
  of export data size and binary size, but ultimately doesn't make
  much sense from the perspective of what should be inlineable.

- Since the inliner walks into every closure created by an outer
  function in addition to starting a walk at every closure, this adds
  an n^2 factor to inlinability analysis.

This CL simply drops this behavior.

In std, this makes 57 more functions inlinable, and disallows inlining
for 10 (due to the basic instability of our bottom-up inlining
approach), for an net increase of 47 inlinable functions (+0.6%).

This will help significantly with the performance of the functions to
be added for #56102, which have a somewhat complicated nesting of
closures with a performance-critical fast path.

The downside of this seems to be a potential increase in export data
and text size, but the practical impact of this seems to be
negligible:

f1caf1aa1c cmd/compile: deadcode unreferenced hidden closures during inlining
When a closure is inlined, it may contain other hidden closures, which
the inliner will duplicate, rendering the original nested closures as
unreachable. Because they are unreachable, they don't get processed in
escape analysis, meaning that go/defer statements don't get rewritten,
which can then in turn trigger errors in walk. This patch looks for
nested hidden closures and marks them as dead, so that they can be
skipped later on in the compilation flow.  NB: if during escape
analysis we rediscover a hidden closure (due to an explicit reference)
that was previously marked dead, revive it at that point.

Fixes #59404.

If the handler returns early due to an unexpected error, it might

signal that the handler has given up and the test should stop.
This won't fix whatever happened in the flake, but might help
us debug it if it happens again.

c00e9285ea runtime: save frame pointer to the stack in signal handlers for arm64
When taking over the goroutine stack in the panic or preemption signal
handlers on arm64, the frame pointer should be saved on the stack (like
the link register) so that frame-pointer unwinding from a panic stack
works properly. Otherwise, tests like TestStackWrapperStackPanic will
fail with the frame pointer check in adjustframe (enabled with
debugCheckBP) when checking the sigpanic frame.

Updates #39524, #58432

e7d59ed204 context: clean up test files
Tests in package context cannot depend directly on package testing due to an import cycle.
We resolved this by having test functions in package context_test (x_test.go) forward to
test functions in package context (context_test.go). This is fragile, since it's easy
to add a test to context_test.go and forget to add the forwarding function, and tests
written in this way cannot easily use testing package features like t.Run for subtests.

It turns out that only four test functions actually use unexported members of package
context. This CL moves all except those four to x_test.go and makes them regular tests.
It also updates TestCause to use t.Run and t.Parallel to parallelize its test cases.
It also adds documentation indicating when tests should be added to each file.
