- Loop signatures are likely incorrect.

[llvm-mca] Move the logic that computes the scheduler's queue usage to the BackendStatistics view.

This patch introduces two new callbacks in the event listener interface to
handle the "buffered resource reserved" event and the "buffered resource
released" event. Every time a buffered resource is used, an event is generated.

Before this patch, the Scheduler (with the help of the ResourceManager) was
responsible for tracking the scheduler's queue usage. However, that design
forced the Scheduler to 'publish' scheduler's queue pressure information through
the Backend interface.

The goal of this patch is to break the dependency between the BackendStatistics
view, and the Backend. Now the Scheduler knows how to notify "buffer
reserved/released" events.  The scheduler's queue usage analysis has been moved
to the BackendStatistics.

Add an analysis printer for must execute reasoning

Many of our loop passes make use of so called "must execute" or "guaranteed to execute" facts to prove the legality of code motion. The basic notion is that we know (by assumption) an instruction didn't fault at it's original location, so if the location we move it to is strictly post dominated by the original, then we can't have introduced a new fault.

At the moment, the testing for this logic is somewhat adhoc and done mostly through LICM. Since I'm working on that code, I want to improve the testing. This patch is the first step in that direction. It doesn't actually test the variant used by the loop passes - I need to move that to the Analysis library first - but instead exercises an alternate implementation used by SCEV. (I plan on merging both implementations.)

[Hexagon] Improve scheduling heuristic for large basic blocks

This patch changes the isLatencyBound heuristic to look at the
path length based upon the number of packets needed to schedule
a basic block. For small basic blocks, the heuristic uses a small
threshold for isLatencyBound. For large basic blocks, the
heuristic uses a large threshold.

The goal is to increase the priority of an instruction in a small
basic block that has a large height or depth relative to the code
size. For large functions, the height and depth are ignored
because it increases the live range of a register and causes more
spills. That is, for large functions, it is more important to
schedule instructions when available, and attempt to keep the defs
and uses closer together.

Bjorn Pettersson [Tue, 20 Mar 2018 09:06:37 +0000 (09:06 +0000)]
[CGP] Avoid segmentation fault when doing PHI node simplifications

Summary:
Made PHI node simplifiations more robust in several ways:

- Minor refactoring to let the SimplificationTracker own the
sets with new PHI/Select nodes that are introduced. This is
maybe not mapping to the original intention with the
SimplificationTracker, but IMHO it encapsulates the logic behind
those sets a little bit better.

- MatchPhiNode can sometimes populate the Matched set with
several entries, where it maps one PHI node to different candidates
for replacement. The Matched set is changed into a SmallSetVector
to make sure we get a deterministic iteration when doing
the replacements.

- As described above we may get several different replacements
for a single PHI node. The loop in MatchPhiSet that is doing
the replacements could end up calling eraseFromParent several
times for the same PHI node, resulting in segmentation faults.
This problem was supposed to be fixed in rL327250, but due to
the non-determinism(?) it only appeared to be fixed (I still
got crashes sometime when turning on/off -print-after-all etc
to get different iteration order in the DenseSets).
With this patch we follow the deterministic ordering in the
Matched set when replacing the PHI nodes. If we find a new
replacement for an already replaced PHI node we replace the
new replacement by the old replacement instead. This is quite
similar to what happened in the rl327250 patch, but here we
also recursively verify that the old replacement hasn't been
replaced already.

- It was really hard to track down the fault described above
(segementation fault due to doing eraseFromParent multiple
times for the same instruction). The fault was intermittent and
small changes in the code, or simply turning on -print-after-all
etc could make the problem go away. This was basically due to
the iteration over PhiNodesToMatch in MatchPhiSet no being
deterministic. Therefore I've changed the data structure for
the SimplificationTracker::AllPhiNodes into an SmallSetVector.
This gives a deterministic behavior.

6 years ago[ORC] Rename SymbolSource to MaterializationUnit, and make the materialization
Lang Hames [Tue, 20 Mar 2018 03:49:29 +0000 (03:49 +0000)]
[ORC] Rename SymbolSource to MaterializationUnit, and make the materialization
operation all-or-nothing, rather than allowing materialization on a per-symbol
basis.

This addresses a shortcoming of per-symbol materialization: If a
MaterializationUnit (/SymbolSource) wants to materialize more symbols than
requested (which is likely: most materializers will want to materialize whole
modules) then it needs a way to notify the symbol table about the extra symbols
being materialized. This process (checking what has been requested against what
is being provided and notifying the symbol table about the difference) has to
be repeated at every level of the JIT stack. Making materialization
all-or-nothing eliminates this issue, simplifying both materializer
implementations and the symbol table (VSO class) API. The cost is that
per-symbol materialization (e.g. for individual symbols in a module) now
requires multiple MaterializationUnits.

Support embedding natvis files in PDBs.

Natvis is a debug language supported by Visual Studio for

PDB with a special name of /src/files/<natvis file name>

[X86] Remove OUT32rr/OUT8rr/OUT32ri/OUT8ri from Sandybridge scheduler model.

PR35590 was already filed for this information being wrong. It's probably better to default to WriteSystem behavior instead of using something completely wrong.

We never codegen this instruction so this doesn't affect much just trying to get them all into a single generated scheduler class in the output.

[X86] Correct regular expression in Zen scheduler model that was excluding JECXZ instruction.

The regex was looking for JECXZ_32 or JECXZ_64, but their is just one instruction called JECXZ. They used to exist as separate instructions, but were merged over 3 years ago.
