[MCA] Highlight kernel bottlenecks in the summary view.

This patch adds a new flag named -bottleneck-analysis to print out information
about throughput bottlenecks.

MCA knows how to identify and classify dynamic dispatch stalls. However, it
doesn't know how to analyze and highlight kernel bottlenecks.  The goal of this
patch is to teach MCA how to correlate increases in backend pressure to backend
stalls (and therefore, the loss of throughput).

From a Scheduler point of view, backend pressure is a function of the scheduler
buffer usage (i.e. how the number of uOps in the scheduler buffers changes over
time). Backend pressure increases (or decreases) when there is a mismatch
between the number of opcodes dispatched, and the number of opcodes issued in
the same cycle.  Since buffer resources are limited, continuous increases in
backend pressure would eventually leads to dispatch stalls. So, there is a
strong correlation between dispatch stalls, and how backpressure changed over
time.

This patch teaches how to identify situations where backend pressure increases
due to:
 - unavailable pipeline resources.
 - data dependencies.

Data dependencies may delay execution of instructions and therefore increase the
time that uOps have to spend in the scheduler buffers. That often translates to
an increase in backend pressure which may eventually lead to a bottleneck.
Contention on pipeline resources may also delay execution of instructions, and
lead to a temporary increase in backend pressure.

Internally, the Scheduler classifies instructions based on whether register /
memory operands are available or not.

An instruction is marked as "ready to execute" only if data dependencies are
fully resolved.
Every cycle, the Scheduler attempts to execute all instructions that are ready
to execute. If an instruction cannot execute because of unavailable pipeline
resources, then the Scheduler internally updates a BusyResourceUnits mask with
the ID of each unavailable resource.

ExecuteStage is responsible for tracking changes in backend pressure. If backend
pressure increases during a cycle because of contention on pipeline resources,
then ExecuteStage sends a "backend pressure" event to the listeners.
That event would contain information about instructions delayed by resource
pressure, as well as the BusyResourceUnits mask.

Note that ExecuteStage also knows how to identify situations where backpressure
increased because of delays introduced by data dependencies.

The SummaryView observes "backend pressure" events and prints out a "bottleneck
report".

Example of bottleneck report:

```
Cycles with backend pressure increase [ 99.89% ]
Throughput Bottlenecks:
  Resource Pressure       [ 0.00% ]
  Data Dependencies:      [ 99.89% ]
   - Register Dependencies [ 0.00% ]
   - Memory Dependencies   [ 99.89% ]
```

A bottleneck report is printed out only if increases in backend pressure
eventually caused backend stalls.

About the time complexity:

Time complexity is linear in the number of instructions in the
Scheduler::PendingSet.

The average slowdown tends to be in the range of ~5-6%.
For memory intensive kernels, the slowdown can be significant if flag
-noalias=false is specified. In the worst case scenario I have observed a
slowdown of ~30% when flag -noalias=false was specified.

We can definitely recover part of that slowdown if we optimize class LSUnit (by
doing extra bookkeeping to speedup queries). For now, this new analysis is
disabled by default, and it can be enabled via flag -bottleneck-analysis. Users
of MCA as a library can enable the generation of pressure events through the
constructor of ExecuteStage.

5 years ago[WebAssembly] Delete ThrowUnwindDest map from WasmEHFuncInfo
Heejin Ahn [Sun, 3 Mar 2019 22:35:56 +0000 (22:35 +0000)]
[WebAssembly] Delete ThrowUnwindDest map from WasmEHFuncInfo

Summary:
Before when we implemented the first EH proposal, 'catch <tag>'
instruction may not catch an exception so there were multiple EH pads an
exception can unwind to. That means a BB could have multiple EH pad
successors.

Now after we switched to the new proposal, every 'catch' instruction
catches an exception, and there is only one catchpad per catchswitch, so
we at most have one EH pad successor, making `ThrowUnwindDest` map in
`WasmEHInfo` unnecessary.

Keeping `ThrowUnwindDest` map in `WasmEHInfo` has its own problems,
because other optimization passes can split a BB that contains possibly
throwing calls (previously invokes), and we have to update the map every
time that happens, which is not easy for common CodeGen passes.

This also correctly updates successor info in LateEHPrepare when we add
a rethrow instruction.

Make the new SanitizerMask code added in r355190 constexpr.

Then, as a consequence, remove the complex set of workarounds for

specific to kNumElem == 2, and will need to be updated if that
constant is increased in the future.

Unfortunately, the current code caused an initialization-order runtime
failure for me in some compilation modes. It appears that in a
toolchain without init-array enabled, the order of initialization of
static data members of a template can be reversed w.r.t. the order
within a file.

In some cases, MaxBECount can be less precise than ExactBECount for AND
and OR (the AND case was PR26207). In the OR test case, both ExactBECounts are
undef, but MaxBECount are different, so we hit the assertion below. This
patch uses the same solution the AND case already uses.

Assertion failed:
   ((isa<SCEVCouldNotCompute>(ExactNotTaken) || !isa<SCEVCouldNotCompute>(MaxNotTaken))
     && "Exact is not allowed to be less precise than Max"), function ExitLimit

This patch also consolidates test cases for both AND and OR in a single
test case.

[Reproducers] Capture and replay interpreter commands.

This patch adds the necessary logic to capture and replay commands
entered into the command interpreter. A DataRecorder shadows the input
and writes its data to a know file. During replay this file is used as
the command interpreter's input.

It's possible to the command interpreter more than once, with a
different input source. We support this scenario by using multiple
buffers. The synchronization for this takes place at the SB layer, where
we create a new recorder every time the debugger input is changed.
During replay we use the corresponding buffer as input.

Daniel Sanders [Sat, 2 Mar 2019 00:12:57 +0000 (00:12 +0000)]
[tblgen] Track CodeInit origins when possible

Summary:
Add an SMLoc to CodeInit that records the source line it originated from.
This allows tablegen to point precisely at portions of code when reporting
errors within the CodeInit. For example, in the upcoming GlobalISel
combiner, it can report undefined expansions and point at the instance of
the expansion. This is achieved using something like:
  SMLoc::getFromPointer(SMLoc::getPointer() +
                        (StringRef - CodeInit::getValue()))

The location is lost when producing a CodeInit by string concatenation so
a fallback SMLoc is required (e.g. the Record::getLoc()) but that's pretty
rare for CodeInits.

There's a reasonable case for extending tracking of a couple other Init
objects, for example StringInit's are often parsed and it would be good to
point inside the string when reporting errors about that. However, location
tracking also harms de-duplication. This is fine for CodeInit where there's
only a few hundred of them (~160 for X86) and it may be worth it for
StringInit (~86k up to ~1.9M for roughly 15MB increase for X86).
However the origin tracking would be a _terrible_ idea for IntInit, BitInit,
and UnsetInit. I haven't measured either of those three but BitInit would
most likely be on the order of increasing the current 2 BitInit values up
to billions.
