These changes make cmd/doc -src deterministic, or, more precisely,
go/ast.MergePackageFiles, which is used by cmd/doc. So far the order of
comments depended on the package file map iteration order.
cmd/doc with -src flag has been inserting and omitting random comments
ever since the addition of -src flag. After investigating the code path
with the debugger, I’ve noticed that ast.File.Comments slice order changes
between invocations of the command. The bug was introduced in 3e24f2d,
which ironically claimed to “fix formatting of -src output”. The commit
implemented the collection of comments by iterating over the map and
c7cdce1 “godoc: make ?m=src mode deterministic” did’t actually make
go/ast.MergePackageFiles deterministic.
I’ve found this issue after running “go doc -src sync.WaitGroup.Wait”.
There are likely other packages and functions affected, but the bug
should be somewhat reproducible across all Go versions.

This partly reverts CL 173417 as it incorrectly documented that Compact
performed HTML escaping and the output was safe to embed inside HTML
<script> tags. This has never been true.
Although Compact does escape U+2028 and U+2029, it doesn't escape <, >
or &. Compact is thus only performing a subset of HTML escaping and it's
output is not safe to embed inside HTML <script> tags.
A more complete fix would be for Compact to either never perform any
HTML escaping, as it was prior to CL 10883045, or to actually perform
the same HTML escaping as HTMLEscape. Neither change is likely safe
enough for go1.13.

Previously users who opted into cgo might have received a bit of a
behavior surprise when their mingw installation defaulted to a

explicitly targeting >=6.1 for internal linkage, propagate these changes
to external linkage too.
While we're at it, we move these values into constant variables so that
they don't become out of sync and allow for easy updating as Go
gradually drops compatibility for older operating systems.

The partially ordered set uses a method named 'dominates' to determine whether
two nodes are partially ordered. Dominates does a depth-first search of the
DAG, beginning at the source node, and returns true as soon as it finds a path
to the target node. In the context of the forest-of-DAGs that makes up the
poset, dominates is not necessarily checking dominance, but is checking
reachability. See the issue tracker for a more detailed discussion of the
difference.
Fortunately, reachability is logically correct everywhere dominates is currently
used in poset.go. Reachability within a DAG is sufficient to establish the
partial ordering (source < target).
This CL changes the name of the method (dominates -> reaches) and updates
all the comments in the file accordingly.

Currently the standard hasher is memhash, which checks whether aes

With this CL, we call aeshash directly, which then redirects to the
fallback hash if aes instructions are not available.
This reduces the overhead for the hash function in the common case,
as it requires just one call instead of two. On architectures which
have no assembly hasher, it's a single jump slower.
