I noticed that there is a Todo comment here. This variable is only used for filename when dump a function's ssa passes result in details. It is no problem to print a function alone, but may be edited by not only one goroutine if dump multiple functions at the same time. Although it looks only dump one function's ssa passes now. As far as I am concerned this variable can be a member variable of the struct Func. I'm not sure if this change is necessary. Looking forward to your advices, thank you very much.

This was done by adding context to their callers, and then
adding context to all call-sites, and then repeating adding

If we are parsing a test output, and the test does not end in the
usual PASS or FAIL line (say, because it panicked), then we need the
exit status of the test binary in order to determine whether the test
passed or failed. If we don't have that status available, we shouldn't
guess arbitrarily — instead, we should omit the final "pass" or "fail"
action entirely.
(In practice, we nearly always DO have the final status, such as when
running 'go test' or 'go tool test2json some.exe'.)

Currently, the GC stores the object marks for checkmarks mode in the
heap bitmap using a rather complex encoding: for one word objects, the
checkmark is stored in the pointer/scalar bit since one word objects
must be pointers; for larger objects, the checkmark is stored in what
would be the scan/dead bit for the second word of the object. This
encoding made more sense when the runtime used the first scan/dead bit
as the regular mark bit, but we moved away from that long ago.
This encoding and overloading of the heap bitmap bits causes a great
deal of complexity in many parts of the allocator and garbage
collector and leads to some subtle bugs like #15903.
This CL moves the checkmarks mark bits into their own per-arena bitmap
and reclaims the second scan/dead bit as a regular scan/dead bit.
I tested this by enabling doubleCheck mode in heapBitsSetType and
running in both regular and GODEBUG=gccheckmark=1 mode.
Fixes#15903.
No performance degradation. (Very slight improvement on a few
benchmarks, but it's probably just noise.)

string indexing in a note handler (which isn't allowed to use the

eliminate the index function, but this CL does down-scope it so make

There is an optimization rule that removes calls to racefuncenter and
racefuncexit, if there are no other race calls in the function. The
rule removes the call to racefuncenter, but it does *not* remove the
store of its argument to the outargs section of the frame. If the
outargs section is now size 0 (because the calls to racefuncenter/exit
were the only calls), then that argument store clobbers the frame
pointer instead.
The fix is to remove the argument store when removing the call to
racefuncenter. (Racefuncexit doesn't have an argument.)

These operations are async unsafe on architectures that use
frame pointers.
The reason is they rely on data being safe when stored below the stack
pointer. They do:
45da69: 48 89 6c 24 f0 mov %rbp,-0x10(%rsp)
45da6e: 48 8d 6c 24 f0 lea -0x10(%rsp),%rbp
45da73: e8 7d d0 ff ff callq 45aaf5 <runtime.duffzero+0x115>
45da78: 48 8b 6d 00 mov 0x0(%rbp),%rbp
This dance ensures that inside duffzero, it looks like there is a
proper frame pointer set up, so that stack walkbacks work correctly if
the kernel samples during duffzero.
However, this instruction sequence depends on data not being clobbered
even though it is below the stack pointer.
If there is an async interrupt at any of those last 3 instructions,
and the interrupt decides to insert a call to asyncPreempt, then the
saved frame pointer on the stack gets clobbered. The last instruction
above then restores junk to the frame pointer.
To prevent this, mark these instructions as async unsafe.
(The body of duffzero is already async unsafe, as it is in package runtime.)

The default ctrl+c handler should process exits in situations where it
makes sense, like console apps, but not in situations where it doesn't,
like libraries or services. Therefore, we should remove the exit(2) so
that the default handler is used for this. This also uses the more
proper windows exit code of STATUS_CONTROL_C_EXIT, with the base case
handler installed by KernelBase.dll. In particular, this helps in the
case of services, which previously would terminate when receiving
shutdown signals, instead of passing them onward to the service program.
In this CL, contrary to CL 244959, we do not need to special case
services with expensive detection algorithms, or rely on hard-coded
library/archive flags.
