Previously by default, we extracted modules to a temporary directory,
then renamed it into place. This failed with ERROR_ACCESS_DENIED on
Windows if another process (usually an anti-virus scanner) opened
files in the temporary directory.
Since Go 1.15, users have been able to set
GODEBUG=modcacheunzipinplace=1 to opt into new behavior: we extract
modules at their final location, and we create and later delete a
.partial file to prevent the directory from being used if we crash.
.partial files are recognized by Go 1.14.2 and later.
With this change, the new behavior is the only behavior.
modcacheunzipinplace is no longer recognized.

Currently on 32-bit systems 8-byte fields in a struct have an alignment
of 4 bytes, which means that atomic instructions may fault. This issue
is tracked in #36606.
Our current workaround is to allocate memory and put any such atomically
accessed fields at the beginning of the object. This workaround fails
because the tiny allocator might not align the object right. This case
specifically only happens with 12-byte objects because a type's size is
rounded up to its alignment. So if e.g. we have a type like:
type obj struct {
a uint64
b byte
}
then its size will be 12 bytes, because "a" will require a 4 byte
alignment. This argument may be extended to all objects of size 9-15
bytes.
So, make this workaround work by specifically aligning such objects to 8
bytes on 32-bit systems. This change leaves a TODO to remove the code
once #36606 gets resolved. It also adds a test which will presumably no
longer be necessary (the compiler should enforce the right alignment)
when it gets resolved as well.
Fixes#37262.

A recent change to improve shifts was generating some
invalid cases when the rule was based on an AND. The
extended mnemonics CLRLSLDI and CLRLSLWI only allow
certain values for the operands and in the mask case
those values were not being checked properly. This
adds a check to those rules to verify that the
'b' and 'n' values used when an AND was part of the rule
have correct values.
There was a bug in some diag messages in asm9. The
message expected 3 values but only provided 2. Those are
corrected here also.
The test/codegen/shift.go was updated to add a few more
cases to check for the case mentioned here.
Some of the comments that mention the order of operands
in these extended mnemonics were wrong and those have been
corrected.

This change incorporates the decision that it should be possible to
run call expansion relatively late in the optimization chain, so that
(1) calls themselves can be exposed to useful optimizations
(2) the effect of selectors on aggregates is seen at the rewrite,
so that assignment of parts into registers is less complicated
(at least I hope it works that way).
That means that selectors feeding into SelectN need to be processed,
and Make* feeding into call parameters need to be processed.
This does however require that call expansion run before decompose
builtins.
This doesn't yet handle rewrites of strings, slices, interfaces,
and complex numbers.

When building a x509 chain the algorithm currently looks for parents
that have a subject key identifier (SKID) that matches the child
authority key identifier (AKID), if it is present, and returns all
matches. If the child doesn't have an AKID, or there are no parents
with matching SKID it will instead return all parents that have a
subject DN matching the child's issuer DN. Prioritizing AKID/SKID
matches over issuer/subject matches means that later in buildChains we
have to throw away any pairs where these DNs do not match. This also
prevents validation when a child has a SKID with two possible parents,
one with matching AKID but mismatching subject DN, and one with a
matching subject but missing AKID. In this case the former will be
chosen and the latter ignored, meaning a valid chain cannot be built.
This change alters how possible parents are chosen. Instead of doing a
two step search it instead only consults the CertPool.byName subject DN
map, avoiding issues where possible parents may be shadowed by parents
that have SKID but bad subject DNs. Additionally it orders the list of
possible parents by the likelihood that they are in fact a match. This
ordering follows this pattern:
* AKID and SKID match
* AKID present, SKID missing / AKID missing, SKID present
* AKID and SKID don't match
In an ideal world this should save a handful of cycles when there are
multiple possible matching parents by prioritizing parents that have
the highest likelihood. This does diverge from past behavior in that
it also means there are cases where _more_ parents will be considered
than in the past. Another version of this change could just retain the
past behavior, and only consider parents where both the subject and
issuer DNs match, and if both parent and child have SKID and AKID also
compare those, without any prioritization of the candidate parents.
This change removes an existing test case as it assumes that the
CertPool will return a possible candidate where the issuer/subject DNs
do not match.

never be used, though.
This CL changes it to only keep used interface methods, for
matching concrete type methods. To do that, when an interface
method is used, the compiler generates a mark relocation. The
linker uses the marker relocations to mark used interface
methods, and only the used ones.

the start of the text section at run time. It is possible that
there is valid code there. If an unreachable method is ever
reached (due to a compiler or linker bug), the execution will
jump to a wrong location but may continue to run for a while,
until it fails with a seemingly unrelated error.
This CL changes it to use -1 for unreachable method instead. At
run time this will resolve to an invalid address, which makes it
fail immediately if it is ever reached.

A test that checks if "tls.(*Conn)" appears in any symbol's name.
tls.Conn is a type, so the string "tls.(*Conn)" can only appear
in the name of a method of Conn. But the test code doesn't use
any of the methods. Not sure why this needs to be live. In
particular, the linker is now able to prune all methods of Conn.
Remove this requirement. In fact, just drop the only_conn test
case, as simply allocating a type doesn't necessarily bring
anything live.

The function takes five 24-bit chunks from the hash, resulting in 120
bits. When base-64 encoded, this results in a 20-byte output string,
which is confirmed by "var dst [chunks * 4]byte".
It seems like the documented math could have been written for a previous
implementation with shorter hashes, using 4 chunks instead of 5, as then
the math checks out.
Since this code has been working correctly for over three years, let's
fix the documentation to reflect the code.

Changes Unmarshal to return an error, instead of
panicking when its value is nil or not a pointer.
This change matches the behavior of other encoding
packages like json.
Fixes#41509.

Split the list of CA certificate directory locations in root_unix.go by
GOOS (aix, *bsd, js, linux, solaris).
On solaris, also include /etc/certs/CA as documented here:
https://docs.oracle.com/cd/E37838_01/html/E61024/kmf-cacerts.html
Same as CL 2208 did for certFiles.

NetBSD does not supply AT_HWCAP, however we still need to initialise
cpu.HWCaps. For now specify the bare minimum until we add some form of
capabilities detection. See
https://golang.org/issue/30824#issuecomment-494901591
Follows CL 174129 which did the same for openbsd/arm64.
