      runtime: adjust the ppc64x memmove and memclr to copy by word as much as it can · 2c911143
      Michael Hudson-Doyle authored 
      Issue #12552 can happen on ppc64 too, although much less frequently in my
testing. I'm fairly sure this fixes it (2 out of 200 runs of oracle.test failed
without this change and 0 of 200 failed with it). It's also a lot faster for
large moves/clears:

      cmd/doc: rearrange the newlines to group better · c978f13a
      Rob Pike authored 
      Main change is that the comment for an item no longer has a blank line
before it, so it looks bound to the item it's about.

Motivating example: go doc.io.read changes from

<
func (l *LimitedReader) Read(p []byte) (n int, err error)
func (r *PipeReader) Read(data []byte) (n int, err error)

    Read implements the standard Read interface: it reads data from the pipe,
    blocking until a writer arrives or the write end is closed. If the write end
    is closed with an error, that error is returned as err; otherwise err is
    EOF.
func (s *SectionReader) Read(p []byte) (n int, err error)
>

to

<
func (l *LimitedReader) Read(p []byte) (n int, err error)
func (r *PipeReader) Read(data []byte) (n int, err error)
    Read implements the standard Read interface: it reads data from the pipe,
    blocking until a writer arrives or the write end is closed. If the write end
    is closed with an error, that error is returned as err; otherwise err is
    EOF.

func (s *SectionReader) Read(p []byte) (n int, err error)
>

Now the comment about PipeReader.Read doesn't look like it's about
SectionReader.

Based on a suggestion by dsnet@, a slight tweak from a CL he suggested
and abandoned.

Fixes #12756,

      text/template, html/template: add block keyword and permit template redefinition · 12dfc3be
      Andrew Gerrand authored 
      This change adds a new "block" keyword that permits the definition
of templates inline inside existing templates, and loosens the
restriction on template redefinition. Templates may now be redefined,
but in the html/template package they may only be redefined before
the template is executed (and therefore escaped).

The intention is that such inline templates can be redefined by
subsequent template definitions, permitting a kind of template
"inheritance" or "overlay". (See the example for details.)

Fixes #3812

      cmd/cgo: only declare real function in gccgo exported header file · 09c6d13a
      Ian Lance Taylor authored 
      When exporting a function using gccgo, we generate two functions: a Go
function with a leading Cgoexp_ prefix, and a C function that calls the
Go function.  The Go function has a name that can not be represented in
C, so the C code needs a declaration with an __asm__ qualifier giving
the name of the Go function.

Before this CL we put that declaration in the exported header file.
Because code would sometimes #include "_cgo_export.h", we added a macro
definition for the C function giving it the name of the declaration.  We
then added a macro undefine in the actual C code, so that we could
declare the C function we wanted.

This rounadabout process worked OK until we started exporting the header
file for use with -buildmode=c-archive and c-shared.  Doing that caused
the code to see the define and thus call the Go function rather than the
C function.  That often works fine, but the C function calls
_cgo_wait_runtime_init_done before calling the Go function, and that
sometimes matters.  This didn't show up in tests because we don't test
using gccgo.  That is something we should fix, but not now.

Fix that by simplifying the code to declare the C function in the header
file as one would expect, and move the __asm__ declaration to the C
code.

      Joel Sing authored 
      As detailed in #11910, the current implementation attempts to execute an area
of memory with unknown content. If the memory is executable, the result is
unpredictable - instead, make the test deterministic by attempting to execute
an instruction that is known to trigger a trap on the given architecture.

The new implementation is written by iant@ and provided via #11910.
