      cmd/compile: fix recursive inimport handling · 011ea879
      Matthew Dempsky authored 
      expandDecl can be called recursively, so it's not an appropriate place
to clean inimport. Instead, move this up to resolve, along with an
appropriate recursion check.

Passes toolstash-check.

      misc/wasm: fix permissions on wasm_exec.js · 4b342899
      Paul Jolly authored 
      Currently wasm_exec.js is executable (0755) yet has no interpreter.
Indeed wasm_exec.js is only ever used as an argument to Node or loaded
via a <script> tag in a browser-loaded HTML file.  Hence the execute
mode bits are superfluous and simply serve to clutter your PATH if
$GOROOT/misc/wasm is on your PATH (as is required if you want to run go
test syscall/js).

      internal/poll: use more fine-grained locking in Splice · 24fb2e01
      Andrei Tudor Călin authored 
      The previous code acquired a read lock on src and a write lock on
dst for the entire duration of Splice. This resulted in deadlock,
in a situation akin to the following:

Splice is blocking, waiting to read from src.

The caller tries to close dst from another goroutine, but Close on
dst blocks in runtime.semacquire, because Splice is still holding a
write lock on it, and the Close didn't unblock any I/O.

The caller cannot unblock the read side of Splice through other means,
because they are stuck waiting in dst.Close().

Use more fine-grained locking instead: acquire the read lock on src
just before trying to splice from the source socket to the pipe,
and acquire the write lock on dst just before trying to splice from
the pipe to the destination socket.

Fixes #25985

      cmd/compile: improve atomic add intrinsics with ARMv8.1 new instruction · 0a7ac93c
      Wei Xiao authored 
      ARMv8.1 has added new instruction (LDADDAL) for atomic memory operations. This
CL improves existing atomic add intrinsics with the new instruction. Since the
new instruction is only guaranteed to be present after ARMv8.1, we guard its
usage with a conditional on CPU feature.

Performance result on ARMv8.1 machine:
name        old time/op  new time/op  delta
Xadd-224    1.05µs ± 6%  0.02µs ± 4%  -98.06%  (p=0.000 n=10+8)
Xadd64-224  1.05µs ± 3%  0.02µs ±13%  -98.10%  (p=0.000 n=9+10)
[Geo mean]  1.05µs       0.02µs       -98.08%

Performance result on ARMv8.0 machine:
name        old time/op  new time/op  delta
Xadd-46      538ns ± 1%   541ns ± 1%  +0.62%  (p=0.000 n=9+9)

      net/http: avoid deferred unlock in ServeMux.shouldRedirect · 1988b3ed
      Emmanuel T Odeke authored 
      CL 96575 introduced concurrency protection for
ServeMux.shouldRedirect with a read lock and deferred unlock.
However, the change produced a noticeable regression.
Instead add the suffix "RLocked" to the function name to
declare that we should hold the read lock as a pre-requisite
before calling it, hence avoiding the defer altogether.

Benchmarks:
name                  old time/op    new time/op    delta
ServeMux-8              63.3µs ± 0%    54.6µs ± 0%  -13.74%  (p=0.000 n=9+9)
ServeMux_SkipServe-8    41.4µs ± 2%    32.7µs ± 1%  -21.05%  (p=0.000 n=10+10)

name                  old alloc/op   new alloc/op   delta
