[interp] Remove return value indirection (#37004)

* [interp] Remove return value indirection

When returning from a method we used to save the return value into frame->retval. We would then have separate opcodes for normal and void call and, depending on the type of call, we would access the retval and push it on the stack. In case of valuetype returns, the value is not returned in the proper space so we have an additional MINT_VTRESULT that copies the return around in the caller frame. In addition to this we had retval, is_void locals, saved as part of the current frame state which just make things confusing and are not needed.

This commit simplifies the call procedure by completely moving the responsability of the return to the called method. Simply put, once a method is ready for the call, it will leave its stack and vtstack to the state after pop-ing the arguments. The called method will then directly push the result to the parent frame's stack/vtstack. This means the calling code doesn't care about the type of the return anymore, the IL instructions after the call will just expect the return on the stack, if any, and use it naturally.

We still make use of frame->retval for interp entry frames (since we don't have a parent frame to push to), for pinvoke and jit_call frames out of convenience, but we should consider removing this variable to further trim down InterpFrame.

* [interp] Remove call opcodes that are no longer necessary

* [interp] Split up CALL and CALLVIRT opcodes

MINT_CALLVIRT is soon to be removed while MINT_CALL is the most common call opcode.

* [interp] Fix jit calls done through MINT_CALLVIRT

The callee should push the vt stack if there is a vt return, except when we are calling out of the interpreter, in which case the calling opcodes handle the push explicitly. We weren't handling the case of exiting the interpreter when doing a jit call through MINT_CALLVIRT. In order to keep the same structure for MINT_CALLVIRT, which doesn't need to know about the vt_res_size, we handle the vtstack change when doing a jit call by caching the return size in the InterpMethod, together with other jit_call information. Maybe we can refactor this later.

* [interp] Cleanup call opcode emitting

Add the opcode and set its data in the same place, making the code
easier to follow.

* [interp] Split up MINT_CALL_NAT in 2 opcodes

This opcode had two different cases embedded in it. Clean up the code,
split the opcode in two, removing also a dirty recursive call.

* [tests] Disable a few tests that fail with this PR due to false pinning

There are over a hundred tests calling GC.WaitForPendingFinalizers and potentially flaky with mono. We might have to disable all of them or tweak them to be mono friendly.

Simple sideloaded profile guided optimization support (#36887)

1. Add code so the runtime can read profile data from a text file and then
make this data available to the jit, so it will be easier to test the jit's
behavior when profile data is available.
2. Add code so the runtime can create profile text files by telling the jit
to insert probes into jitted code that write into a persistent buffer, which
is saved to text at shutdown. This is mainly intended to make creation of the
sideloaded profile data files easier, since their internal structure must
exactly match artifacts from jitted methods.
3. Add a mode where jit-instrumented Tier0 code can feed counts into Tier1
jitting. This is an experiment to see what benefit, if any, might accrue from
having  profile data available for Tier1 jitting.

External format is text so it can be edited by hand or checked into the repo
alongside tests. Binary format would be more compact but opaque.

In all cases the jit internally sees a profile buffer identical to the one it
sees with IBC; the only minor changes in the jit are to initialize the count
field of each probe entry to zero and to only emit the entry helper call for
prejitted IBC.

Only root methods are instrumented, and only root method blocks are given
profile weights. Broadening to handle inlinees is future work, facilitated by
the new capabilites added here.

When it gets to an assignment to a local variable or a local field,
it checks whether the assignment is the first reference to the local
(or to the parent of the local field), and, if so, it may do one of two
optimizations:
1. If the following conditions are true:
        the local is untracked,
        the rhs of the assignment is 0,
        the local is guaranteed to be fully initialized in the prolog,
   then the explicit zero initialization is removed.
2. If the following conditions are true:
        the assignment is to a local (and not a field),
        the local is not lvLiveInOutOfHndlr or no exceptions can be thrown
             between the prolog and the assignment,
        either the local has no gc pointers or there are no gc-safe points
             between the prolog and the assignment,
    then the local is marked with lvHasExplicitInit, which tells the codegen
    not to insert zero initialization for this local in the prolog.

This addresses one of the examples in #2325 and 5 examples in #1007.

integrate into other runtimes, replacing current C++ library
implementation, when time permits.

Until that happens, we will need to make sure changes done in C++
code base gets ported over to C library. The amount of changes going
into the native library should however be small and if major changes
needs to be done, we should first make sure to move over to use the
shared version of event pipe C-library in CoreCLR and then only do
changes into shared version of the library.

Port is currently mapping existing C++ code base, no focus on rewrite
or change current implementation (unless needed to port code over to C).

Library source files are currently placed into mono/eventpipe folder
and build as a separate library, linked into runtime, but will be
moved when ready to be shared between runtimes. We might also move
all code into a loadable library and p/invokes, depending on size,
at least for Mono runtime targeting mobile devices.

There is also a unit test runner under mono/eventpipe/tests using
eglib test runner, running through a set of unit tests covering
the eventpipe library implementation.

Library is split up over a couple of source files closely mapping
corresponding coreclr source files. Most code could be shared between
runtimes and artifacts that are runtime specific, like
locks/lists/maps/strings/pal layer etc, a shim API is defined in ep-rt.h
and ep-rt-types.h that gets implemented by the targeted runtime consuming
the event pipe C library, like ep-rt-mono.h and ep-rt-types-mono.h.
All function in the shim API is small and should be inlinable. For example,
locking the configuration lock is declared like this in ep-rt.h:

bool
ep_rt_config_aquire (void);
and in ep-rt-mono.h it is implemented like this:

static
inline
bool
ep_rt_config_aquire (void)
{
ep_rt_spin_lock_aquire (ep_rt_mono_config_lock_get ());
return true;
}

and CoreCLR should implement the function using its corresponding
locking primitives. NOTE, since we primarily target Mono in initial
port there might smaller adjustments needed to the shim API once
bringing it over to CoreCLR, but those changes/adjustments can be
done when needed.

Since library could be shared, it tries to standardize on common C99
data types when available. If there are runtime specific types needed,
they are declared in ep-rt-types.h and implemented by each runtime in
corresponding file. Most of library is currently following Mono coding
guidelines.

For shared types naming is done like this, EventPipe[Type], like
EventPipeProvider. This naming follow naming of other types in Mono
as well as CoreCLR. There is one exception to this rule, types that
are runtime specific implementation, naming is following function
naming with a _t prefix, like ep_rt_session_provider_list_t,
that is a list specific type, implemented by each runtime. This is
done to make it easier to see difference of types implemented in
the runtime specific shim and types implemented in the shared
library API surface.

Since library shim implemented by targeted runtime will be called
by C code, it can't throw exceptions, the C library should however
compile under C++, meaning that CoreCLR's shim should be able to
use C++ constructions as long as it don't throw any exceptions.

Library function naming follows the following pattern, for "public"
functions included in ep-*.h , ep_ + object + action, so for example,
ep_config_create_provider, corresponds to EventPipe::Configuration::CreateProvider
in C++ library. For "private/internal" functions not, ep_ prefix is
dropped, but object + action is still preserved, for example
config_create_provider and function is marked as being static
when possible. If a function assumes a lock is held when getting
called, it is using _lock_held (similar to SAL annotations) postfix
to indicate that function doesn't claim lock and if function needs
lock to be held by caller, it will assert that condition on enter
(similar to PRECONDITION(EventPipe::IsLockOwnedByCurrentThread())).

Library uses asserts internally to validate state and conditions.
This is a debug/checked build assert that should be excluded in
release builds. It is defined in EP_ASSERT and should be redefined
by targeted runtime. Private/internal functions asserts incorrect
input parameters and state, while "public" functions return back
error to caller when detecting incorrect input parameters.
Incorrect state can still be assert in all kinds of functions.

Getters/Setters are setup for accessing type members. All functions
except a type's own alloc/init/fini/free implemented in ep-*.c are
not allowed to use direct type member access and should go through
available inlinable getter/setter functions. There is also a way
to build the library that catches incorrect use of members at
compile time (not in ep-*-internals.c since it include
alloc/init/fini/free implementations, but in other source files).

Types that can be stack allocated offers a init/fini function pairs.
Types that should only be heap allocated, alloc/free, and types
supporting both stack/heap, implements alloc/init/fini/free. Since C
can't prevent incorrect usage patterns, the implementation needs to
follow correct life time management patterns. Types allocated using
alloc should be freed with corresponding free function. For example,
ep_event_alloc should be freed by ep_event_free, the init/fini methods
are then called by the alloc/free implementations. For types supporting
stack allocation and allocated on stack or aggregated within other types,
init must be called before first use and fini before going out of scope.

Ownership of allocated objects is only considered complete on successful
function calls. If a function fails, caller still owns resource and need
to take actions.

Library uses UTF8 strings internally, mainly since Mono runtime already
uses that and it is more portable. Number of strings in the library is
limited, and in cases where stream protocol uses UTF16 strings,
a prealloc string is stored on the type, reducing need to do multiple
UTF8 -> UTF16 conversions over the lifetime of the type.

NOTE, this is first commit setting up most of the direction of the library
and (as part of doing that) ported a great deal of eventpipe code and
added ~40 native unittests. It is however not complete, or fully working,
so there will be several follow up commit building on top of this work
in order to get complete library.

4 years agoOptimize decommit (#35896)
Peter Sollich [Tue, 26 May 2020 12:21:47 +0000 (05:21 -0700)]
Optimize decommit (#35896)

Optimize the way we decommit memory on both SVR and WKS GC.

Key ideas for SVR GC:
 - in decommit_ephemeral_segment_pages, instead of decommitting right there, just remember what we intended to decommit.

- in gc_thread function, have the thread with heap_number 0 periodically wake up and do gradual decommits for all heaps by calling the new method decommit_ephemeral_pages_step on them. This way, the decommit is not part of the GC pause and does not contribute to it.

- decommit_ephemeral_pages_step will decommit a "reasonable" amount of space per heap and time interval, and return how much it decomitted. A return value of 0 indicates no further progress.

- take into account Gen 1 budget size and Gen 1 free list when computing how much memory we are likely to need soon.

For WKS GC:

- As for SVR GC, take Gen 1 budget size and Gen 1 free list into account.

- Decommit gradually, taking into account the elapsed time since the last GC to make sure decommit does not become a major part of the GC pause.

As the validation scenario, I used an enhanced version of GCPerfSim that can be made to go through "phases", where the phases are programmed by an input text file. To cause decommits, I varied the amount of survivorship between phases - in one phase, one object out of 30 survived, in the next phase 1 out of 300 survived. 10 GB were allocated on each thread in each phase, and the phases with high and low survivorship were repeated 10 times. Test machine was an i9-7900X, 1 allocating thread was used for WKS GC, and 10 allocating threads for SVR GC.

Metrics directly influenced by decommitting memory were selected:
- Wall clock time (influenced both by GC pause time and page faults during allocation)
- GC pause time (especially in SVR GC, impacted by decommitting during GC pause)
- CPU samples spent decommitting
- CPU samples spend in KiPagefault triggered by allocator

Comparison with the master branch gave these results (numbers are medians of 3 runs):

SVR                                       Baseline    Optimized
================================
Wallclock time (secs):         127.456        106.581
GC pause time (secs):          50.120           41.293
Samples in decommit:           5,467            1,918
Samples in KiPagefault        77,872          21,449
 from allocator

WKS                                      Baseline    Optimized
================================
Wallclock time (secs):          57.213            54.321
GC pause time (secs):          21.422            22.060
Samples in decommit:             465                   48
Samples in KiPagefault         5,505               3,509
 from allocator

So all metrics are noticeably improved, with the exception of GC pause time for WKS. Given the scatter in the pause time numbers, it seems likely that this slight apparent regression is spurious.

Today on Unix, we create an anonymous pipe via pipe/pipe2 to be used for stdin/stdout/stderr on processes created by Process.Start.  We then wrap the resulting file descriptors with FileStreams to hand out via Process.StandardInput/Output/Error.  This has a few issues, however. Any async operations on the resulting stream (or wrapping stream reader) will actually be async-over-sync, and that in turn means that a) any async read will end up blocking a thread pool thread until it's satisified, and b) the operation isn't cancelable.  The implications of (b) are obvious, and the problem with (a) is that code which launches a bunch of processes and uses BeginOutput/ErrorReadLine or the like will end up blocking a bunch of thread pool threads.

This change replaces the pipe/pipe2 calls with socketpair calls, and instead of wrapping the resulting file descriptors with FileStream, wraps them in Sockets and NetworkStreams.  This gives us the full capabilities of the networking stack, which fully supports asynchronous and cancelable reads and writes.
