[dev.regabi] cmd/compile: split out package typecheck [generated]
This commit splits the typechecking logic into its own package,
the first of a sequence of CLs to break package gc into more
manageable units.

[dev.regabi] cmd/compile: move type size calculations into package types [generated]
To break up package gc, we need to put these calculations somewhere
lower in the import graph, either an existing or new package. Package types
already needs this code and is using hacks to get it without an import cycle.
We can remove the hacks and set up for the new package gc by moving the
code into package types itself.

[dev.regabi] cmd/compile: group known symbols, packages, names [generated]
There are a handful of pre-computed magic symbols known by
package gc, and we need a place to store them.
If we keep them together, the need for type *ir.Name means that
package ir is the lowest package in the import hierarchy that they
can go in. And package ir needs gopkg for methodSymSuffix
(in a later CL), so they can't go any higher either, at least not all together.
So package ir it is.
Rather than dump them all into the top-level package ir
namespace, however, we introduce global structs, Syms, Pkgs, and Names,
and make the known symbols, packages, and names fields of those.

[dev.regabi] cmd/compile: remove Node.Left etc [generated]
This automated CL adds type assertions on the true branches of
n.Op() equality tests, to redeclare n with a more specific type, when
it is safe to do so. (That is, when n is not reassigned with a more
general type, when n is not reassigned and then used outside the
scope, and so on.) All the "unsafe" times that the automated tool
would avoid have been removed or rewritten in earlier CLs, so that
after this CL and the next one, which removes the use of ir.Nod,
every use of the Left, Right, and so on methods is done using concrete
types, never the Node interface.
Having done that, the CL locks in the progress by deleting many of
the access methods, including Left, SetLeft and so on, from the
Node interface.
There are still uses of Name, Func, Sym, some of the tracking
bits, and a few other miscellaneous fields, but all the main access
methods are gone from the Node interface. The others will be cleaned
up in smaller CLs.
Passes buildall w/ toolstash -cmp.

[dev.regabi] cmd/compile: remove ir.Nod [generated]
Rewrite all uses of ir.Nod and friends to call the IR constructors directly.
This gives the results a more specific type and will play nicely with
introduction of more specific types throughout the code in a followup CL.
Passes buildall w/ toolstash -cmp.

[dev.regabi] cmd/dist: automatically bootstrap cmd subdirs
We want almost all cmd subdirectories anyway, and relative to the cost of the rest of toolchain bootstrapping, copying/rewriting a few extra source files is way cheaper than the engineering cost of forgetting to maintain these lists as we split out new packages. While here, also add cmd/internal/archive (and make it compile with Go 1.4) because it'll be needed in subsequent refactorings anyway; and skip files starting with # (emacs temporary files) and test files ending with _test.go.

cmd/link: handle grouped resource sections
The Go PE linker does not support enough generalized PE logic to properly handle .rsrc sections gracefully. Instead a few things are special cased for these. The linker also does not support PE's "grouped sections" features, in which input objects have several named sections that are sorted, merged, and renamed in the output file. In the past, more sophisticated support for resources or for PE features like grouped sections have not been necessary, as Go's own object formats are pretty vanilla, and GNU binutils also produces pretty vanilla objects where all sections are already merged. However, GNU binutils is lagging with arm support, and here LLVM has picked up the slack. In particular, LLVM has its own rc/cvtres combo, which are glued together in mingw LLVM distributions as windres, a command line compatible tool with binutils' windres, which supports arm and arm64. But there's a key difference between binutils' windres and LLVM's windres: the LLVM one uses proper grouped sections. So, this commit adds grouped sections support for resource sections to the linker. We don't attempt to plumb generic support for grouped sections, just as there isn't generic support already for what resources require. Instead we augment the resource handling logic to deal with standard two-section resource objects. We also add a test for this, akin to the current test for more vanilla binutils resource objects, and make sure that the rsrc tests are always performed. Fixes #42866. Fixes #43182.

test: trigger SIGSEGV instead of SIGTRAP in issue11656.go
In issue11656.go, it tests that if the runtime can get a reasonable traceback when it faults at a non-function PC. It does it by jumping to an address that contains an illegal or trap instruction. When it traps, the SIGTRAP crashes the runtime. This CL changes it to use an instruction that triggers SIGSEGV. This is due to two reasons: - currently, the handling of bad PC is done by preparePanic, which is only used for a panicking signal (SIGSEGV, SIGBUS, SIGFPE), not a fatal signal (e.g. SIGTRAP). - the test uses defer+recover to get a traceback, which only works for panicking signals, not fatal signals. Ideally, we should handle all kinds of faults (SIGSEGV, SIGBUS, SIGILL, SIGTRAP, etc.) with a nice traceback. I'll leave this for the future. This CL also adds RISCV64 support. Fixes #43283.

[dev.regabi] cmd/compile,cmd/link: initial support for ABI wrappers
Add compiler support for emitting ABI wrappers by creating real IR as opposed to introducing ABI aliases. At the moment these are "no-op" wrappers in the sense that they make a simple call (using the existing ABI) to their target. The assumption here is that once late call expansion can handle both ABI0 and the "new" ABIInternal (register version), it can expand the call to do the right thing. Note that the runtime contains functions that do not strictly follow the rules of the current Go ABI0; this has been handled in most cases by treating these as ABIInternal instead (these changes have been made in previous patches). Generation of ABI wrappers (as opposed to ABI aliases) is currently gated by GOEXPERIMENT=regabi -- wrapper generation is on by default if GOEXPERIMENT=regabi is set and off otherwise (but can be turned on using "-gcflags=all=-abiwrap -ldflags=-abiwrap"). Wrapper generation currently only workd on AMD64; explicitly enabling wrapper for other architectures (via the command line) is not supported. Also in this patch are a few other command line options for debugging (tracing and/or limiting wrapper creation). These will presumably go away at some point. Updates #27539, #40724.

runtime: correct error handling in several FreeBSD syscall wrappers
The FreeBSD syscall convention uses the carry flag to indicate whether an error has occured. The sys_umtx_op, thr_new, and pipe2 syscall wrappers were failing to account for this convention and silently suppressing errors as a result. This commit corrects these wrappers by copying the pattern used by the other fallible syscall wrappers. Note that futexsleep1 must now explicitly ignore the ETIMEDOUT error from sys_umtx_op. Previously ETIMEDOUT was implicitly ignored because sys_umtx_op never returned an error. Fixes #43106.

[dev.regabi] runtime: fix ABI targets in runtime.panic{Index,Slice} shims
Fix up the assembly shim routines runtime.panic{Index,Slice} and
friends so that their tail calls target ABIInternal and not ABI0
functions. This is so as to ensure that these calls don't go through
an ABI0->ABIInternal wrapper (which would throw off the machinery in
the called routines designed to detect whether the violation happened
in the runtime).
Note that when the compiler starts emitting real register calls to
these routines, we'll need to rewrite them to update the arg size and
ensure that args are in the correct registers. For example, the
current shim
TEXT runtime·panicIndex<ABIInternal>(SB),NOSPLIT,$0-16
MOVQ AX, x+0(FP)
MOVQ CX, y+8(FP)
JMP runtime·goPanicIndex<ABIInternal>(SB)
will need to change to
TEXT runtime·panicIndex<ABIInternal>(SB),NOSPLIT,$0
// AX already set up properly
MOVQ CX, BX // second argument expected in BX
JMP runtime·goPanicIndex<ABIInternal>(SB)

runtime: use _exit on darwin
On darwin, where we use libc for syscalls, when the runtime exits, it calls libc exit function, which may call back into user code, e.g. invoking functions registered with atexit. In particular, it may call back into Go. But at this point, the Go runtime is already exiting, so this wouldn't work. On non-libc platforms we use exit syscall directly, which doesn't invoke any callbacks. Use _exit on darwin to achieve the same behavior. No test for now, as it doesn't pass on all platforms (see trybot run of PS2). May fix #42465. May fix #43294.

Prior to CL 232298, sysmon could detect these overrun timers and manually start an M to run them. With this fallback gone, the bug actually prevents timer execution indefinitely.

runtime: skip wakep call in wakeNetPoller on Plan 9
This was part of a performance improvement made by CL 232298 to reduce timer latency. On multiprocessor Plan 9 machines, it triggers memory faults often enough that the builder test suite never completes successfully. See issue #42303 for discussion. As shown by the benchmark result below, worst case latency on plan9_arm is very bad even with the wakep call in place - in the tickers-per-P=1 case, a 3ms timer is 270ms late. Skipping the wakep call and running the benchmark again shows some cases worse, some better. The performance cost doesn't seem excessive for this temporary workaround which makes the plan9_arm builders usable again.
