      mime: do a pre-allocation in encodeWord · 3fb3ca08
      isharipo authored 
      The preallocated memory size is comparable to bytes.Buffer bootstraping
array length (bytes.Buffer was used before rewrite to strings.Builder).

Without preallocation, encodeWord does more than one allocation for
almost any possible input.

The regression happens because bytes.Buffer did a 80-bytes allocation
at the beginning of encodeWord while strings.Builder did several
smaller allocations (started with cap=0).

Comparison with reported regression:

  name           old time/op    new time/op    delta
  QEncodeWord-4     781ns ± 1%     593ns ± 1%  -24.08%  (p=0.008 n=5+5)

  name           old alloc/op   new alloc/op   delta
  QEncodeWord-4      152B ± 0%       80B ± 0%  -47.37%  (p=0.008 n=5+5)

  name           old allocs/op  new allocs/op  delta
  QEncodeWord-4      5.00 ± 0%      2.00 ± 0%  -60.00%  (p=0.008 n=5+5)

Comparison with buffer solution (like before strings.Builder, but
without sync pool for buffer re-using):

  name           old time/op    new time/op    delta
  QEncodeWord-4     595ns ± 1%     593ns ± 1%     ~     (p=0.460 n=5+5)

  name           old alloc/op   new alloc/op   delta
  QEncodeWord-4      160B ± 0%       80B ± 0%  -50.00%  (p=0.008 n=5+5)

  name           old allocs/op  new allocs/op  delta
  QEncodeWord-4      2.00 ± 0%      2.00 ± 0%     ~     (all equal)

We avoid allocation in buf.String(), as expected.

Fixes #25379

      This commit addresses a FIXME left in the code of wasm_exec.js to
properly get the upper 32 bit of a JS number to be stored as an
64-bit integer. A bitshift operation is not possible, because in
JavaScript bitshift operations only operate on the lower 32 bits.

      net: skip socket hungry test on iOS · 3027932a
      Elias Naur authored 
      The iOS builder recently gained access to the GO_BUILDER_NAME
environment variable, which in turn enabled some net tests that
were previously guarded by testenv.Builder() == "". Some such tests
have been disabled because they don't work; others have increased
the pressure on open file descriptors, pushing the low iOS limit of
250.

Since many net tests run with t.Parallel(), the "too many open files"
error hit many different tests, so instead of playing whack-a-mole,
lower the file descriptor demand by skipping the most file
descriptor hungry test, TestTCPSpuriousConnSetupCompletionWithCancel.

Before:

$ GO_BUILDER_NAME=darwin-arm64 GOARCH=arm64 go test -short -v net
...
Socket statistical information:
...
(inet4, stream, default): opened=5245 connected=193 listened=75 accepted=177 closed=5399 openfailed=0 connectfailed=5161 listenfailed=0 acceptfailed=143 closefailed=0
...

After:

$ GO_BUILDER_NAME=darwin-arm64 GOARCH=arm64 go test -short -v net
...
Socket statistical information:
...
(inet4, stream, default): opened=381 connected=194 listened=75 accepted=169 closed=547 openfailed=0 connectfailed=297 listenfailed=0 acceptfailed=134 closefailed=0
...

Fixes #25365 (Hopefully).

      testing: allow marking subtest and subbenchmark functions as Helpers · 15f2cbf4
      Diogo Pinela authored 
      Since subtests and subbenchmarks run in a separate goroutine, and thus
a separate stack, this entails capturing the stack trace at the point
tb.Run is called. The work of getting the file and line information from
this stack is only done when needed, however.

Continuing the search into the parent test also requires temporarily
holding its mutex. Since Run does not hold it while waiting for the
subtest to complete, there should be no risk of a deadlock due to this.

Fixes #24128

      cmd/compile: improve undo of poset · 67656ba7
      Giovanni Bajo authored 
      prove uses the poset datastructure in a DFS walk, and always undoes
it back to its pristine status. Before this CL, poset's undo of
a new node creation didn't fully deallocate the node, which means
that at the end of prove there was still some allocated memory pending.

This was not a problem until now because the posets used by prove
were discarded after each function, but it would prevent recycling
them between functions (as a followup CL does).

      cmd/compile: plumb prologueEnd into DWARF · 7bac2a95
      David Chase authored 
      This marks the first instruction after the prologue for
consumption by debuggers, specifically Delve, who asked
for it.  gdb appears to ignore it, lldb appears to use it.

The bits for end-of-prologue and beginning-of-epilogue
are added to Pos (reducing maximum line number by 4x, to
1048575).  They're added in cmd/internal/obj/<ARCH>.go
(currently x86 only), so the compiler-proper need not
deal with them.

The linker currently does nothing with beginning-of-epilogue,
but the plumbing exists to make it easier in the future.

This also upgrades the line number table to DWARF version 3.

This CL includes a regression in the coverage for
testdata/i22558.gdb-dbg.nexts, this appears to be a gdb
artifact but the fix would be in the preceding CL in the
stack.

      cmd/compile: assign and preserve statement boundaries. · c2c1822b
      David Chase authored 
      A new pass run after ssa building (before any other
optimization) identifies the "first" ssa node for each
statement. Other "noise" nodes are tagged as being never
appropriate for a statement boundary (e.g., VarKill, VarDef,
Phi).

Rewrite, deadcode, cse, and nilcheck are modified to move
the statement boundaries forward whenever possible if a
boundary-tagged ssa value is removed; never-boundary nodes
are ignored in this search (some operations involving
constants are also tagged as never-boundary and also ignored
because they are likely to be moved or removed during
optimization).

Code generation treats all nodes except those explicitly
marked as statement boundaries as "not statement" nodes,
and floats statement boundaries to the beginning of each
same-line run of instructions found within a basic block.

Line number html conversion was modified to make statement
boundary nodes a bit more obvious by prepending a "+".

The code in fuse.go that glued together the value slices
of two blocks produced a result that depended on the
former capacities (not lengths) of the two slices.  This
causes differences in the 386 bootstrap, and also can
sometimes put values into an order that does a worse job
of preserving statement boundaries when values are removed.

Portions of two delve tests that had caught problems were
incorporated into ssa/debug_test.go.  There are some
opportunities to do better with optimized code, but the
next-ing is not lying or overly jumpy.

Over 4 CLs, compilebench geomean measured binary size
increase of 3.5% and compile user time increase of 3.8%
(this is after optimization to reuse a sparse map instead
of creating multiple maps.)

This CL worsens the optimized-debugging experience with
Delve; we need to work with the delve team so that
they can use the is_stmt marks that we're emitting now.

The reference output changes from time to time depending
on other changes in the compiler, sometimes better,
sometimes worse.

This CL now includes a test ensuring that 99+% of the lines
in the Go command itself (a handy optimized binary) include
is_stmt markers.

      path/filepath: make Abs("") return working directory on Windows · 91f07c57
      Dmitri Shuralyov authored 
      The current Abs docs say:

	// If the path is not absolute it will be joined with the current
	// working directory to turn it into an absolute path.

The empty string is not an absolute path, so the docs suggest that the
empty string should be joined with the current working directory to
turn it into an absolute path. This was already the case on all
platforms other than Windows. Per the decision in issue #24441,
this change makes it work on Windows too.

Since the empty string is not a valid path for the purposes of calling
os.Stat on it, we can't simply add the empty string test case to
absTests, which TestAbs uses. It would error when trying to do:

	info, err := os.Stat(path)

I didn't find a good way to modify TestAbs to handle this situation
without significantly complicating its code and compromising the test.
So, a separate test is created for testing Abs on empty string input.

Fixes #24441.

      cmd/internal/obj/x86: use named consts for movtab Z-cases · e405c9cc
      quasilyte authored 
      Use 0-terminated opbyte sequences for Zlit-like movtabs instead of E=0xff.

movCodeFullPtr is unused (load full ptr is unsupported), but it should
be removed in a separate CL (if removed at all).

Passes toolstash-check.
