Add cooperative suspend aware threads for hybrid suspend. (mono/mono#15204)

* Add cooperative suspend aware threads for hybrid suspend.

When running in hybrid suspend and having threads in blocking mode, GC Safe
mode, threads will still be preemptive suspended. This is done to make sure
compatibility is kept with embedders since current embedding API is not coop
aware. If, however the external attached threads promise to follow the coop
rules for a thread in Safe mode, it could still be possible to have them
running, making sure they won't be preempted when running STW. Unlocking this
possibility could have large performance wins if embedding threads runs a lot
of native code on threads attached to runtime.

This commit adds support for a new pair of API's where an external thread can
mark itself as cooperative suspend aware. Doing that guarantees the runtime
that it will follow all rules as dictated by cooperative suspend when a thread
is in safe mode. The change only goes one way since this is a lifetime commitment
for a thread. Once’s set, thread will be kept running when in safe mode.

[aot profiler] Listen for commands on given port (mono/mono#14936)

* [aot profiler] Listen for commands on given port

Extended the aot profiler so, that it can receive commands over the network.

Added new option `port=PORT`, which enables command server and specifies
the port the server should listen at.

We have 2 commands so far.

    save ... save the profile data to socket and close it
    quit ... quit the profiler. it also saves the profile to the file
             in case the output option was specified.

It makes the aot profiling much easier to use on Android as we don't need to
save the profile to a file on the device. That means we don't need to set
`<application android:debuggable="true"/>` flag, which changes the Android
app behavior and thus influence the profile itself. It is also convenient way
for IDEs to retrieve the aot profiles.

Example use for Xamarin.Android. Save and receive the profile data:

adb shell setprop debug.mono.profile aot:verbose,port=9999
adb forward tcp:9999 tcp:9999

Increase max size of localloc and localloc_imm on amd64. (mono/mono#15374)

We hit the following assert when doing full AOT of some assemblies:

wrong maximal instruction length of instruction localloc (expected 96, got 99)
Assertion: should not be reached at mono\mono\mini\mini-amd64.c:6801

Turns out that that size could be hit when a couple of things happens as part
of lowering OP_LOCALLOC and OP_LOCALLOC_IMM:

sreg1 is not RAX, RCX or RDI
dreg is not RAX, RCX or RDI
cfg->param_area is bigger than 127

Fix is to increase max size of the instruction, from 96 -> 120 (same as x86).

5 years ago[arm] set exception handling model to dwarf for iOS
Bernhard Urban [Fri, 21 Jun 2019 14:26:24 +0000 (16:26 +0200)]
[arm] set exception handling model to dwarf for iOS

We recently switched the AOT compiler for iOS armv7 from 32bit host to 64bit host. At the same time we _also_ switched from LLVM 3.6 to the newer LLVM 6.0 fork we support.

In a Xamarin.iOS Release build for iOS armv7 exception handling would crash. Specifically the problem was that the exception object wasn't properly injected into the handler block. The way it works is, that the exception handler machinery passes the pointer to the exception object via `r0`.

With the newer LLVM the generated code of the exception handling block
looks like this:
```
LBB1_15:                                @ %EH_CLAUSE0_BB3
Ltmp8:
ldr r0, [sp, mono/mono#24]
str r0, [sp, mono/mono#4]
ldr r0, [sp, mono/mono#28]
ldr r0, [sp, mono/mono#12]
ldr r0, [r0]
cmp r0, mono/mono#0
beq LBB1_17
```
thus overwriting `r0`, so that the pointer to the exception object is lost.  With the older LLVM 3.6 the generated code looks like this:
```
LBB1_8:                                 @ %EH_CLAUSE0_BB3
Ltmp8:
str r0, [sp, mono/mono#4]
ldr r0, [r6]
cmp r0, mono/mono#0
beq LBB1_10
```
correctly storing the exception object into a stack slot for later usage.

After some time I figured out that there are _different_ exception handling models. Depending on the model, the exception pointer is passed in `r0` or not:
https://github.com/mono/llvm/blob/mono/mono@2bd2f1db1803f7b36687e5abf912c69baa848305/lib/Target/ARM/ARMISelLowering.cpp#L14416-L14428

`SjLj` stands for "SetJump / LongJump" and  means that exception handling is implemented with this. On iOS this is the default model that is used. We want `dwarf` instead, so we tell this `llc` now and the generated code handles it correctly.

So why was it working before? In our older LLVM 3.6 fork we hardcoded it:
https://github.com/mono/llvm/blob/mono/mono@f80899cb3eb75f7f5640b4519e83bd96991bffb8/lib/Target/ARM/ARMISelLowering.cpp#L756-L762

The `-exception-model=` option is also not available in LLVM 3.6.

Make copy_stack_data support configurable.

By default when called through macros like MONO_ENTER_GC_UNSAFE
code will always dump current registers into stack space on hybrid/coop.
The registers will be scanned but only when hitting a GC and when running
in GC unsafe, that will only happen when we block in the enter or hit a safe
point at a later point in time. There are currently a couple of frequent
scenarios where we go into GC safe when thread won't be suspended and in
that case the copy of the registers will only reflect the state when
entering GC unsafe.

Commits add option to enable/disable copy_stack_data support in configure step:
--enable-copy-stack-data, --disable-copy-stack-data.

copy_stack_data is enabled by default on all platforms except desktop platforms
macos, linux and windows (both 32/64-bit), since these platforms already support
full context as well as capabilities to scan the stack of a running thread.

[debugger] Debugger doesn't break on unhandled exceptions  (mono/mono#15234)

* I've tested the MonoTests.DebuggerTests.UnhandledException_2 test on VsWin using .net Framework and I think the test is wrong because the first break is in throw and the next break will be on breakpoint.
In our implementation we were ignoring the unhandled exception and stopping only on breakpoint.

[jit] Make alias analysis properly handle alias cloberring (mono/mono#15255)

Alias analysis attempts to remove indirection when using OP_LDADDR (which fetches the address of a variable). For example :

ldaddr r1 <- r0
load_mem r2 <- r1

is equivalent to

mov r2 <- r0

The remembered r1 alias needs to be forgotten in case r1 is changed. We were handling this for direct assignment with MOV, but not for the more subtle case where an alias to r1 would be passed to a call, which could lead to changing r1.

5 years agoFix race conditions in mono_lazy_initialize,
Jay Krell [Fri, 14 Jun 2019 07:52:48 +0000 (00:52 -0700)]
Fix race conditions in mono_lazy_initialize,
which is meant to be all about handling race conditions.

1. Less severe:
Add missing read barrier to mono_lazy_initialize().

This is unfortunate.

The general pattern of:

if initialized
  use the data
else:
  initialize the data, possibly with lots of locks and barriers
  mark initialized

is racy, because "use the data" can be scheduled ahead of "if initialized".

"Barriers come in pairs" generally, and this was missing one.

It depends somewhat. If the data is all pointers, initialized in the else path,
from null to non-null, and use includes dereferencing, which is a common
but not universal case, then it is ok on all non-Alpha processors, due
to "data dependency".

But if the data includes reading globals, then there is a race.

This is a bit of a slow down on fast paths on arm, and possibly
other architectures.

There are barrier-free ways to solve this, involving a thread local,
that should seriously be considered, and applied throughout the runtime.

The runtime has a lot of on-demand initialization and a lot of looks racy.

See www.open-std.org/jtc1/sc22/wg21/docs/papers/2008/n2660.htm.
Which would have to be adopted to be coop-friendly which should not be difficult.

Notice that the existing "lazy" mechanism is also not coop-friendly.
That is not changed by this PR.

2. Change `status` to `*lazy_init` to fix severe race condition.

5 years agoDeadlock in loader when using bundling. (mono/mono#15061)
Johan Lorensson [Fri, 14 Jun 2019 09:20:28 +0000 (11:20 +0200)]
Deadlock in loader when using bundling. (mono/mono#15061)

We can hit the following deadlock when loading assemblies (using reflection)
together with bundling:

One thread calls mono_assembly_open_from_bundle, that will take assemblies lock
and then try to load assembly. If this race with a different load of the
same assemblies, one will lose, and that method will call mono_image_close that
in turn will call unload hook (mono_class_unregister_image_generic_subclasses)
that will take loader lock.

If we at the same time have a different thread that calls mono_class_create_from_typedef
, it will take loader lock and then it might end up calling mono_assembly_load_reference
that will take assemblies lock, but since that thread takes the locks
in different order compare to first thread, they could deadlock.

Looking into the use of assemblies lock in mono_assembly_open_from_bundle it
uses a static variable, bundles, that is not protected in other scenarios
and only set by mono_register_bundled_assemblies, normally called during
boot. The method called in the loop mono_image_open_from_data_internal is called
at several places without locks (and looks internal using image lock), so that
doesn't need to be protected. The rest is local data access and the only thing the
lock could do is serialize the whole loop between threads (but that shouldn't be needed).

Fix will remove the locking and also eliminating the incorrect lock order
causing the deadlock.
