This is a port of CL 274615, adapted to go/types. The only change was in
the positioning of expected errors in vardecl.src: in go/types they are
positioned on the identifier.

In ABIInternal, reserve X15 as constant zero, and use it to zero
memory. (Maybe there can be more use of it?)
The register is zeroed when transition to ABIInternal from ABI0.
Caveat: using X15 generates longer instructions than using X0.
Maybe we want to use X0?

Mark the syscall wrappers as ABIInternal, as they have addresses
taken from Go code, and it is important to call to them without
wrappers.
Previously, the wrapper is just a single JMP instruction, which
makes it not matter. In the next CL we'll make the wrapper
actually have a frame. The real wrappers will mess up things
such as stack alignment for C ABI.
This doesn't look really nice, but I don't know how we can do
better...

In the linker's deadcode pass we decode type symbols for
interface satisfaction analysis. When linking against Go shared
libraries, the type symbol may come from a shared library, so it
doesn't have data in the current module being linked, so we cannot
decode it. We already have code to skip DYNIMPORT symbols. However,
this doesn't actually work, because at that point the type symbols'
names haven't been mangled, whereas they may be mangled in the
shared library. So the symbol definition (in shared library) and
reference (in current module) haven't been connected.
Skip decoding type symbols of type Sxxx (along with DYNIMPORT)
when linkShared.
Note: we cannot skip all type symbols, as we still need to mark
unexported methods defined in the current module.
Fixes#44031.

CL 279423 introduced a regression in this test as it incorrectly laid
out various instructions. In the case of arm, the second instruction
was overwriting the first. In the case of 386, amd64 and s390x, the
instructions were being appended to the end of the slice after 64
zero bytes.
This was causing test failures on "linux/s390x on z13".

We add entries to the defer list at panic/goexit time on-the-fly for
frames with open-coded defers. We do this so that we can correctly
process open-coded defers and non-open-coded defers in the correct order
during panics/goexits. But we need to remove entries for open-coded
defers from the defer list when there is a recover, since those entries
may never get removed otherwise and will get stale, since their
corresponding defers may now be processed normally (inline).
This bug here is that we were only removing higher-up stale entries
during a recover if all defers in the current frame were done. But we
could have more defers in the current frame (as the new test case
shows). In this case, we need to leave the current defer entry around
for use by deferreturn, but still remove any stale entries further along
the chain.
For bug 43921, simple change that we should abort the removal loop for
any defer entry that is started (i.e. in process by a still
not-recovered outer panic), even if it is not an open-coded defer.
This change does not fix bug 43920, which looks to be a more complex fix.

NewFile requires the file descriptor to be either closed
through the returned File instance, or to stay valid at least
until the finalizer runs during garbage collection.
These requirements are easily violated when file descriptors
are closed via unix.Close, or when the *File returned by
NewFile is garbage collected while the underlying file descriptor is
still in use.
This commit adds further documentation for NewFile and Fd, making it
explicit that using naked file descriptors is subject to constraints
due to garbage collection of File objects.

case in any realistic scenario where the FastCGI protocol is spoken
over sockets or pairs of pipes.
Since tests that use nopWriteCloser don't care about any output
generate by child.Serve(), we change nopWriteCloser to provide
a dummy Write method.
Remove the locking added in CL 252417, since it causes a deadlock
during write as reported in #43901. The race in tests no longer
happens thanks to the aforementioned change to nopWriteCloser.
Fixes#43901.
Updates #41167.

CL 261677 fixed a logic issue in walk's alias detection, where it was
checking the RHS expression instead of the LHS expression when trying
to determine the kind of assignment. However, correcting this exposed
a latent issue with assigning to result parameters in functions with
defers, where an assignment could become visible earlier than intended
if a later expression could panic.
Fixes#43835.

This reverts CLs 274450 and 279492, except for the new tests.
The new race test is changed to skip, as it now fails.
We can try again for 1.17.
Original CL descriptions:
html/template: attach functions to namespace
The text/template functions are stored in a data structure shared by
all related templates, so do the same with the original, unwrapped,
functions on the html/template side.
html/template: avoid race when escaping updates template

This CL expands internal-abi.md to cover Go's memory layout rules and
then uses this to specify the calling convention more precisely.

This adds a document specifying the internal ABI (specifically the
calling convention). This document lives in the Go tree (rather than
the proposal repository) because the intent is for it to track the
reality in the compiler.
Updates #40724.

Currently the only mention of go_asm.h is buried in a confusing
section about the runtime-specific go_tls.h header. We actually want
people to use go_asm.h, so this CL adds a section with a proper
discussion of this header. As part of this, we remove the discussion
of go_asm.h from the go_tls.h section and clean up what remains.
I stumbled on this when working on the internal ABI specification. I
wanted to refer to stable documentation on how to access struct fields
from assembly and found there was none.
