CL 198544 broke the linux/arm64 build because it declares emptyfunc for GOARCH=arm64, but only freebsd/arm64 defines it. Make it a static assembly function specific for freebsd/arm64 and remove the stub.

Previously, TestAtomicStop used a hard-coded 2-second timeout. That empirically is not long enough on certain builders. Rather than adjusting it to a different arbitrary value, use a slice of the overall timeout for the test binary. If everything is working, we won't block nearly that long anyway.

Currently, shrinkstack will not shrink a stack on Windows if gp.m.libcallsp != 0. In general, we can't shrink stacks in syscalls because the syscall may hold pointers into the stack, and in principle this is supposed to be preventing that for libcall-based syscalls (which are direct syscalls from the runtime). But this test is actually broken and has been for a long time. That turns out to be okay because it also appears it's not necessary. This test is racy. g.m points to whatever M the G was last running on, even if the G is in a blocked state, and that M could be doing anything, including making libcalls. Hence, observing that libcallsp == 0 at one moment in shrinkstack is no guarantee that it won't become non-zero while we're shrinking the stack, and vice-versa. It's also weird that this check is only performed on Windows, given that we now use libcalls on macOS, Solaris, and AIX. This check was added when stack shrinking was first implemented in CL 69580044. The history of that CL (though not the final version) suggests this was necessary for libcalls that happened on Go user stacks, which we never do now because of the limited stack space. It could also be defending against user stack pointers passed to libcall system calls from blocked Gs. But the runtime isn't allowed to keep pointers into the user stack for blocked Gs on any OS, so it's not clear this would be of any value. Hence, this checks seems to be simply unnecessary. Rather than simply remove it, this CL makes it defensive. We can't do anything about blocked Gs, since it doesn't even make sense to look at their M, but if a G tries to shrink its own stack while in a libcall, that indicates a bug in the libcall code. This CL makes shrinkstack panic in this case. For #10958, #24543, since those are going to rearrange how we decide that it's safe to shrink a stack.

The x86 assembler supports an "ADJSP" pseudo-op that compiles to an ADD/SUB from SP. Unfortunately, while this seems perfect for an instruction that would allow obj to continue to track the SP/FP delta, obj currently doesn't do that. As a result, FP-relative references won't work and, perhaps worse, the pcsp table will have the wrong frame size. We don't currently use this instruction in any assembly or generate it in the compiler, but this is a perfect instruction for solving a problem in #24543. This CL makes ADJSP useful by incorporating it into the SP delta logic. One subtlety is that we do generate ADJSP in obj itself to open a function's stack frame. Currently, when preprocess enters the loop to compute the SP delta, it may or may not start at this ADJSP instruction depending on various factors. We clean this up by instead always starting the SP delta at 0 and always starting this loop at the entry to the function. Why not just recognize ADD/SUB of SP? The danger is that could change the meaning of existing code. For example, walltime1 in sys_linux_amd64.s saves SP, SUBs from it, and aligns it. Later, it restores the saved copy and then does a few FP-relative references. Currently obj doesn't know any of this is happening, but that's fine once it gets to the FP-relative references. If we taught obj to recognize the SUB, it would start to miscompile this code. An alternative would be to recognize unknown instructions that write to SP and refuse subsequent FP-relative references, but that's kind of annoying. This passes toolstash -cmp for std on both amd64 and 386.

According to MSDN, "If the data has the REG_SZ, REG_MULTI_SZ or REG_EXPAND_SZ type, this size includes any terminating null character or characters unless the data was stored without them. [...] If the data has the REG_SZ, REG_MULTI_SZ or REG_EXPAND_SZ type, the string may not have been stored with the proper terminating null characters. Therefore, even if the function returns ERROR_SUCCESS, the application should ensure that the string is properly terminated before using it; otherwise, it may overwrite a buffer." It's therefore dangerous to pass it off unbounded as we do, and in fact this led to crashes on real systems.

Generate inline code at defer time to save the args of defer calls to unique (autotmp) stack slots, and generate inline code at exit time to check which defer calls were made and make the associated function/method/interface calls. We remember that a particular defer statement was reached by storing in the deferBits variable (always stored on the stack). At exit time, we check the bits of the deferBits variable to determine which defer function calls to make (in reverse order). These low-cost defers are only used for functions where no defers appear in loops. In addition, we don't do these low-cost defers if there are too many defer statements or too many exits in a function (to limit code increase). When a function uses open-coded defers, we produce extra FUNCDATA_OpenCodedDeferInfo information that specifies the number of defers, and for each defer, the stack slots where the closure and associated args have been stored. The funcdata also includes the location of the deferBits variable. Therefore, for panics, we can use this funcdata to determine exactly which defers are active, and call the appropriate functions/methods/closures with the correct arguments for each active defer. In order to unwind the stack correctly after a recover(), we need to add an extra code segment to functions with open-coded defers that simply calls deferreturn() and returns. This segment is not reachable by the normal function, but is returned to by the runtime during recovery. We set the liveness information of this deferreturn() to be the same as the liveness at the first function call during the last defer exit code (so all return values and all stack slots needed by the defer calls will be live). I needed to increase the stackguard constant from 880 to 896, because of a small amount of new code in deferreturn(). The -N flag disables open-coded defers. '-d defer' prints out the kind of defer being used at each defer statement (heap-allocated, stack-allocated, or open-coded). Cost of defer statement [ go test -run NONE -bench BenchmarkDefer$ runtime ] With normal (stack-allocated) defers only: 35.4 ns/op With open-coded defers: 5.6 ns/op Cost of function call alone (remove defer keyword): 4.4 ns/op Text size increase (including funcdata) for go binary without/with open-coded defers: 0.09% The average size increase (including funcdata) for only the functions that use open-coded defers is 1.1%. The cost of a panic followed by a recover got noticeably slower, since panic processing now requires a scan of the stack for open-coded defer frames. This scan is required, even if no frames are using open-coded defers: Cost of panic and recover [ go test -run NONE -bench BenchmarkPanicRecover runtime ] Without open-coded defers: 62.0 ns/op With open-coded defers: 255 ns/op A CGO Go-to-C-to-Go benchmark got noticeably faster because of open-coded defers: CGO Go-to-C-to-Go benchmark [cd misc/cgo/test; go test -run NONE -bench BenchmarkCGoCallback ] Without open-coded defers: 443 ns/op With open-coded defers: 347 ns/op Updates #14939 (defer performance) Updates #34481 (design doc) Change-Id: I63b1a60d1ebf28126f55ee9fd7ecffe9cb23d1ff Reviewed-on: https://go-review.googlesource.com/c/go/+/202340Reviewed-by:

A Rat is represented via a quotient a/b where a and b are Int values. To make it possible to use an uninitialized Rat value (with a and b uninitialized and thus == 0), the implementation treats a 0 denominator as 1. Rat.Num and Rat.Denom return pointers to these values a and b. Because b may be 0, Rat.Denom used to first initialize it to 1 and thus produce an undesirable side-effect (by changing the Rat's denominator). This CL changes Denom to return a new (not shared) *Int with value 1 in the rare case where the Rat was not initialized. This eliminates the side effect and returns the correct denominator value. While this is changing behavior of the API, the impact should now be minor because together with (prior) CL https://golang.org/cl/202997, which initializes Rats ASAP, Denom is unlikely used to access the denominator of an uninitialized (and thus 0) Rat. Any operation that will somehow set a Rat value will ensure that the denominator is not 0. Fixes #33792. Updates #3521.

To make it possible to use an uninitialized Rat value (with a and b uninitialized and thus == 0), the implementation treats a 0 denominator as 1. For each operation we check if the denominator is 0, and then treat it as 1 (if necessary). Operations that create a new Rat result, normalize that value such that a result denominator 1 is represened as 0 again. This CL changes this behavior slightly: 0 denominators are still interpreted as 1, but whenever we (safely) can, we set an uninitialized 0 denominator to 1. This simplifies the code overall.

On ARM and ARM64, during a VDSO call, the g register may be temporarily clobbered by the VDSO code. If a signal is received during the execution of VDSO code, we may not find a valid g reading the g register. In CL 192937, we conservatively assume g is nil. But this approach has a problem: we cannot handle the signal in this case. Further, if the signal is not a profiling signal, we'll call badsignal, which calls needm, which wants to get an extra m, but we don't have one in a non-cgo binary, which cuases the program to hang. This is even more of a problem with async preemption, where we will receive more signals than before. I ran into this problem while working on async preemption support on ARM64. In this CL, before making a VDSO call, we save the g on the gsignal stack. When we receive a signal, we will be running on the gsignal stack, so we can fetch the g from there and move on. We probably want to do the same for PPC64. Currently we rely on that the VDSO code doesn't actually clobber the g register, but this is not guaranteed and we don't have control with. Idea from discussion with Dan Cross and Austin. Should fix #34391.

benchcmp was moved out of misc into x/tools in CL 60100043 in 2014, and then replaced by a forwarding script in CL 82710043. Five years have since passed, and the forwarding script has outlived its usefulness. It's now more confusing than helpful. Delete it.

It turns out that Windows has "legitimate" keys that have bogus type values or bogus lengths that don't correspond with their type. On up to date Windows 10 systems, this test always fails for this reason. These keys exist because of bugs in Microsoft's code. This commit works around the problem by simply blacklisting known instances. It also expands the error message a bit so that we can make adjustments should the problem ever happen again, and reformats the messages so that it makes copy and pasting into the blacklist easier.

Since CL 194600, search.CleanPaths preserves characters after '@' in each argument. This was done so that paths could be cleaned while version queries were preserved. However, local and absolute file paths may contain '@' characters. With this change, '@' is treated as a normal character by search.CleanPaths in local and absolute paths.

This was disabled due to a report that the App Store rejects the symbol __sysctl. However, we use the sysctl symbol, which is fine. The __sysctl symbol is used by x/sys/unix, which needs fixing instead. So, this commit reenables sysctl on iOS, so that things like net.InterfaceByName can work again. This reverts CL 193843, CL 193844, CL 193845, and CL 193846.

Since the new timers run on g0, which does not have a race context, we add a race context field to the P, and use that for timer functions. This works since all timer functions are in the standard library.
