811167e2c9 cmd/link: do not pass -Bsymbolic for PE DLLs
This is only a valid option on ELF. Binutils accepts it, but LLVM
rejects it, so for Windows, it's best to just omit it.

a51daac840 cmd/link: set SizeOfRawData rather than VirtualSize in COFF files for .bss section
GCC and Clang both set the SizeOfRawData field rather than the
VirtualSize field for communicating the size of the .bss section. As a
consequence, LLD does not look at VirtualSize and collapses the .bss
section into whatever is around it, resulting in runtime crashes. This
commit changes the logic so that if the requested "file size" is 0, then
the SizeOfRawData field is set rather than the VirtualSize field as the
sole length marker.

b3b65f2176 runtime: enable race detector on openbsd/amd64
Now that this commit[1] has landed in LLVM the .syso file can be generated for
OpenBSD.

With the changes to src/runtime running the sample race[2] detects the data
race as expected.

Based on golang/go#39464 (https://go-review.googlesource.com/c/go/+/237057) from
Aaron Bieber <deftly@gmail.com>, however the race_openbsd_amd64.syso file has
been built on OpenBSD 6.4 and necessary changes added to race.bash.

5e804ba17d cmd/compile: use transitive relations for slice len/cap in poset
Currently, we keep track of slice len by mapping from slice ID to
len/cap SSA value. However, slice len/cap can have multiple SSA values,
so when updating fact table for slice len/cap, we only update in one
place.

Instead, we can take advantage of the transitive relations provided by
poset. So all duplicated slice lens are set as equal to one another.
When updating fact table for one, that fact will be reflected to all
others. The same mechanism is applied for slice cap.

Removes 15 bounds checks from std/cmd.

Fixes #42603

1126bbb82a go/parser: return ast.BadExpr for missing index operands
The parser was returning the indexed operand when a slice or index or
instance expression was missing any index arguments (as in the
expression `a[]`). This can result in returning an *ast.Ident for the
LHS of the (invalid) assignment `a[] = ...` -- in this case parsing the
LHS as just `a`. Unfortunately, as the indexed operand `a` has already
been resolved, this results in a panic for duplicate resolution.

Fix this by instead returning an ast.BadExpr. This can suppress some
subsequent errors from the typechecker, but those errors may or may not
be correct anyway. Other interpretations, such as an *ast.IndexExpr with
bad or missing X, run into potential misinterpretations downstream (both
caused errors in go/types and/or gopls).

04903476fe cmd/compile: reject some rare looping CFGs in shortcircuit
One CFGs that shortcircuit looks for is:
 
p   q
 \ /
  b
 / \
t   u

The test case creates a CFG like that in which p == t.
That caused the compiler to generate a (short-lived) invalid phi value.

Fix this with a relatively big hammer: Disallow single-length loops entirely.
This is probably overkill, but it such loops are very rare.
This doesn't change the generated code for anything in std.

It generates worse code for the test case:
It no longer compiles the entire function away.

0f66fb7b85 go/internal/gccgoimporter: fix up gccgo installation test
Change the TestInstallationImporter testpoint to query type
information for sort.Search instead of sort.Ints. The latter function
changed recently (1.16 timeframe), parameter "a" is now "x". A better
candidate for this sort of query is sort.Search, which has been stable
for a while.

Fixes #44425.

e78e04ce39 cmd/compile: fix panic in DWARF-gen handling obfuscated code
DWARF generation uses variable source positions (file/line/col) as a
way to uniquely identify locals and parameters, as part of the process
of matching up post-optimization variables with the corresponding
pre-optimization versions (since the DWARF needs to be in terms of the
original source constructs).

This strategy can run into problems when compiling obfuscated or
machine-generated code, where you can in some circumstances wind up
with two local variables that appear to have the same name, file,
line, and column. This patch changes DWARF generation to skip over
such duplicates as opposed to issuing a fatal error (if an
obfuscation tool is in use, it is unlikely that a human being will be
able to make much sense of DWARF info in any case).

Fixes #44378.

26713b5fef go/types: don't write during sanitizeInfo if nothing has changed
In its final phase, the typechecker walks the types it produces to
ensure that no unexpanded type instances leak through the API. However,
this also walks shared types (such as those in the universe scope),
resulting in a potential data race during concurrent typechecking
passes.

Fix this by being careful not to write if nothing needs to be changed.
Since any shared types should already be sanitized, this should
eliminate data races.

06b86e9803 cmd/compile: fix check to avoid creating new closure function when typechecking inline body
By default, when typechecking a closure, tcClosure() creates a new
closure function. This should really be done separate from typechecking.
For now, we explicitly avoid creating a new closure function when
typechecking an inline body (in ImportedBody). However, the heuristic
for determining when we are typechecking an inline body was not correct
for double nested closures in an inline body, since CurFunc will then be
the inner closure, which has a body.

So, use a simple global variable to indicate when we typechecking an
inline body. The global variable is fine (just like ir.CurFunc), since
the front-end runs serially.

Fixes #44325

02e5a8fdfc runtime: ignore SPWRITE in syscall functions
netbsd/amd64's Syscall9 changes SP using ADD and SUB,
which are treated as SPWRITEs (they are not accounted for
in the sp-adjust tracking, and there are too many functions that
would report mismatched stack adjustments at RET if they were).
A traceback starting in Syscall9 as saved by entersyscall complains
about the SPWRITE-ness unnecessarily, since the PC/SP are saved
at the start of the function. Ignore SPWRITE in that case.

netbsd/arm's Syscall6 also changes SP (R13), using a direct write.
So even if we could handle the ADD/SUB in the amd64 case or
rewrote that assembly, we'd still be stuck with a more difficult
problem in this case. Ignoring the SPWRITE fixes it.

Example crashes:

fa18f224c3 runtime/pprof: disable TestMorestack on macOS under race detector
This is failing but only under the race detector.
It doesn't really seem fair to expect pprof to find
specific profile events with the race detector slowing
everything down anyway.
