As discussed in
https://github.com/golang/go/issues/32463#issuecomment-506833421
the classification of deadline-based timeouts as "temporary" errors is a
historical accident. I/O timeouts used to be duration-based, so they
really were temporary--retrying a timed-out operation could succeed. Now
that they're deadline-based, timeouts aren't temporary unless you reset
the deadline.
Drop ErrTemporary from Go 1.13, since its definition is wrong. We'll
consider putting it back in Go 1.14 with a clear definition and
deprecate net.OpError.Temporary.

We shouldn't mask to desired registers if we haven't masked out all the
forbidden registers yet. In this path we haven't masked out the nospill
registers yet. If the resulting mask contains only nospill registers, then
allocReg fails.
This can only happen on resultNotInArgs-marked instructions, which exist
only on the ARM64, MIPS, MIPS64, and PPC64 ports.
Maybe there's a better way to handle resultNotInArgs instructions.
But for 1.13, this is a low-risk fix.

Currently when we coalesce memory we make a sysHugePage call
(MADV_HUGEPAGE) to ensure freed and coalesced huge pages are treated as
such so the scavenger's assumptions about performance are more in line
with reality.
Unfortunately we do it way too often because we do it if there was any
change to the huge page count for the span we're coalescing into, not
taking into account that it could coalesce with its neighbors and not
actually create a new huge page.
This change makes it so that it only calls sysHugePage if the original
huge page counts between the span to be coalesced into and its neighbors
do not add up (i.e. a new huge page was created due to alignment). Calls
to sysHugePage will now happen much less frequently, as intended.

This change adds physHugePageShift which is defined such that
1 << physHugePageShift == physHugePageSize. The purpose of this variable
is to avoid doing expensive divisions in key functions, such as
(*mspan).hugePages.
This change also does a sweep of any place we might do a division or mod
operation with physHugePageSize and turns it into bit shifts and other
bitwise operations.
Finally, this change adds a check to mallocinit which ensures that
physHugePageSize is always a power of two. osinit might choose to ignore
non-powers-of-two for the value and replace it with zero, but mallocinit
will fail if it's not a power of two (or zero). It also derives
physHugePageShift from physHugePageSize.
This change helps improve the performance of most applications because
of how often (*mspan).hugePages is called.

Currently, GODEBUG=sbrk=1 mode aligns allocations by their type's
alignment. You would think this would be the right thing to do, but
because 64-bit fields are only 4-byte aligned right now (see #599),
this can cause a 64-bit field of an allocated object to be 4-byte
aligned, but not 8-byte aligned. If there is an atomic access to that
unaligned 64-bit field, it will crash.
This doesn't happen in normal allocation mode because the
size-segregated allocation and the current size classes will cause any
types larger than 8 bytes to be 8 byte aligned.
We fix this by making sbrk=1 mode use alignment based on the type's
size rather than its declared alignment. This matches how the tiny
allocator aligns allocations.
This was tested with
GOARCH=386 GODEBUG=sbrk=1 go test sync/atomic
This crashes with an unaligned access before this change, and passes
with this change.
This should be reverted when/if we fix#599.

Changes "was loaded as" to "was required as". This is slightly more
precise, since it hints at a requirement edge in the module version
graph.

With gccgo, if we generate getg inlined, the backend may cache
the address of the TLS variable, which will become invalid after
a thread switch.
Currently there is no known bug for this. But if we didn't
implement this carefully, we may get subtle bugs. This CL adds a
test that will fail loudly if this is wrong. (See also
https://go.googlesource.com/gofrontend/+/refs/heads/master/libgo/runtime/proc.c#333
and an incorrect attempt CL 185337.)
Note: at least on Linux/AMD64, even with an incorrect
implementation, this only fails if the test is compiled with
-fPIC, which is not the default setting for gccgo test suite. So
some manual work is needed. Maybe we could extend the test suite
to run the runtime test with more settings (e.g. PIC and static).

Do not allow a pseudo-version derived from a canonical tag to refer to
the same revision as the tag itself. It's unnecessary (because
canonical tags already have a total ordering) and confusing (the
pseudo-version appears to come after the tag, but actually refers to
the exact same revision).

This error occurs when a module is loaded with one name (for example,
github.com/golang/lint) but declares a different path in its go.mod
(golang.org/x/lint). The current text "unexpected module path" is
confusing. It doesn't explain why the path was unexpected, and it's
not clear what was expected.
With this change, the error text includes the module and version
containing the go.mod file with the error, the declared module path,
and the loaded module path. The paths are vertically aligned so
differences are visually obvious. As with other module version errors,
the shortest chain of requirements is printed.
This change supercedes CL 158477.

These functions are compiler generated, and as such are only available
in the internal ABI. Doing this avoids generating an alias symbol.
Doing that avoids confusion between unmangled and mangled type symbols.

If the module path declared in the go.mod file does not match the path
we are trying to resolve, a build using that module is doomed to fail.
Since we know that the module path does not match in the underlying
repo, we also know that the requested module does not exist at the
requested version.
Therefore, we should reject that version in Stat with a “not exist”
error — sooner rather than later — so that modload.Query will continue
to check other candidate paths (for example, with a major-version
suffix added or removed).
