[SCEV] Ensure ScalarEvolution::createAddRecFromPHIWithCastsImpl properly handles out of range truncations of the start and accum values

Summary:
 When constructing the predicate P1 in ScalarEvolution::createAddRecFromPHIWithCastsImpl() it is possible
for the PHISCEV from which the predicate is constructed to be a SCEVConstant instead of a SCEVAddRec. If
this happens, then the cast<SCEVAddRec>(PHISCEV) in the code will assert.

 Such a PHISCEV is possible if either the start value or the accumulator value is a constant value
that not equal to its truncated value, and if the truncated value is zero.

 This patch adds tests that demonstrate the cast<> assertion, and fixes this problem by checking
whether the PHISCEV is a constant before constructing the P1 predicate; if it is, then P1 is
equivalent to one of P2 or P3. Additionally, if we know that the start value or accumulator
value are constants then we check whether the P2 and/or P3 predicates are known false at compile
time; if either is, then we bail out of constructing the AddRec.

[X86] Remove unnecessary (v4f32 (X86vzmovl (v4f32 (scalar_to_vector FR32X)))) patterns

We had already disabled the pattern for SSE4.1 and SSE4.2. But it got re-enabled for AVX and AVX512.

With SSE41 we rely on a separate (v4f32 (X86vzmovl VR128)) pattern to select blendps with a xorps to create zeroess. And a separate (v4f32 (scalar_to_vector FR32X)) to select a COPY_TO_REG_CLASS to move FR32 to VR128

The same thing can happen for AVX with vblendps and those separate patterns already exist.

For AVX512, (v4f32 (X86vzmov VR128)) will select a VMOVSS instruction instead of VBLENDPS due to their not being a EVEX VBLENDPS. This is what we were getting out of the larger pattern anyway. So the larger pattern is unneeded for AVX512 too.

For SSE1-SSSE3 we can rely on (v4f32 (X86vzmov VR128)) selecting a MOVSS similar to AVX512. Again this is what the larger pattern did too.

So the only real change here is that AVX1/2 now properly outputs a VBLENDPS during isel instead of a VMOVSS to match SSE41. Most tests didn't notice because the two address instruction pass knows how to turn VMOVSS into VBLENDPS to get an independent destination register.

To maximize the opportunity, we do canonicalization of code sequence before merging compares.
For the above example, the input for this pass looks like:

cmplwi r3, 0
beq    0, .LBB0_3
cmpwi  r3, -1
bgt    0, .LBB0_4

So, before merging two compares, we canonicalize it as

cmpwi  r3, 0       ; cmplwi and cmpwi yield same result for beq
beq    0, .LBB0_3
cmpwi  r3, 0       ; greather than -1 means greater or equal to 0
bge    0, .LBB0_4

The generated code should be

cmpwi  r3, 0
beq    0, .LBB0_3
bge    0, .LBB0_4

can not (since the addresses they have been permanently bound to will change

[ORC] Refactor OrcRemoteTarget code to expose its RPC API, reduce
code duplication in the client, and improve error propagation.

This patch moves the OrcRemoteTarget rpc::Function declarations from
OrcRemoteTargetRPCAPI into their own namespaces under llvm::orc::remote so that
they can be used in new contexts (in particular, a remote-object-file adapter

Code duplication in OrcRemoteTargetClient (especially in loops processing the
code, rw-data and ro-data allocations) is removed by moving the loop bodies
into their own functions.

Error propagation is (slightly) improved by adding an ErrorReporter functor to
the OrcRemoteTargetClient -- Errors that can't be returned (because they occur
in destructors, or behind stable APIs that don't provide error returns) can be
sent to the ErrorReporter instead. Some methods in the Client API are also
changed to make better use of the Expected class: returning Expected<T>s rather
than returning Errors and taking T&s to store the results.

Other than saving on compile-time by pruning the possible MaxVF candidates, this patch fixes pr34438 which exposed the following flow:
1. Short trip count identified -> Don't bail out, set OptForSize:=True to avoid tail-loop and runtime checks.
2. Compute MaxVF returned 16 on a target supporting AVX512.

4. Bail out because TripCount = 8, VF = 16, TripCount % VF !=0 means we need a tail loop.

I believe this is causing us to generate some duplicate patterns because tablegen's isomorphism checks don't catch isomorphism between the patterns as written in the td. It only detects isomorphism in the commuted variants it tries to create. The the unmasked 231 and 132 memory forms are isomorphic as written in the td file so we end up keeping both. I think we precommute the 132 pattern to fix this.

Keith Wyss [Sun, 3 Sep 2017 00:03:47 +0000 (00:03 +0000)]
[XRay][tools] Function call stack based analysis tooling for XRay traces

This change introduces a subcommand to the llvm-xray tool called
"stacks" which allows for analysing XRay traces provided as inputs and
accounting time to stacks instead of just individual functions. This
gives us a more precise view of where in a program the latency is
actually attributed.

The tool uses a trie data structure to keep track of the caller-callee
relationships as we process the XRay traces. In particular, we keep
track of the function call stack as we enter functions. While we're
doing this we're adding nodes in a trie and indicating a "calls"
relatinship between the caller (current top of the stack) and the callee
(the new top of the stack). When we push function ids onto the stack, we
keep track of the timestamp (TSC) for the enter event.

When exiting functions, we are able to account the duration by getting
the difference between the timestamp of the exit event and the
corresponding entry event in the stack. This works even if we somehow
miss the exit events for intermediary functions (i.e. if the exit event
is not cleanly associated with the enter event at the top of the stack).

The output of the tool currently provides just the top N leaf functions
that contribute the most latency, and the top N stacks that have the
most frequency. In the future we can provide more sophisticated query
mechanisms and potentially an export to database feature to make offline
analysis of the stack traces possible with existing tools.

Summary:
ZExt and SExt from i8 to i16 aren't implemented in the autogenerated fast isel table because normal isel does a zext/sext to 32-bits and a subreg extract to avoid a partial register write or false dependency on the upper bits of the destination. This means without handling in fast isel we end up triggering a fast isel abort.

We had no custom sign extend handling at all so while I was there I went ahead and implemented sext i1->i8/i16/i32/i64 which was also missing. This generates an i1->i8 sign extend using a mask with 1, then an 8-bit negate, then continues with a sext from i8. A better sequence would be a wider and/negate, but would require more custom code.

Fast isel tests are a mess and I couldn't find a good home for the tests so I created a new one.

The test pr34381.ll had to have fast-isel removed because it was relying on a fast isel abort to hit the bug. The test case still seems valid with fast-isel disabled though some of the instructions changed.

Summary:
After a discussion with Rekka, i believe this (or a small variant)
should fix the remaining phi-of-ops problems.

Rekka's algorithm for completeness relies on looking up expressions
that should have no leader, and expecting it to fail (IE looking up
expressions that can't exist in a predecessor, and expecting it to
find nothing).

Unfortunately, sometimes these expressions can be simplified to
constants, but we need the lookup to fail anyway.  Additionally, our
simplifier outsmarts this by taking these "not quite right"
expressions, and simplifying them into other expressions or walking
through phis, etc.  In the past, we've sometimes been able to find
leaders for these expressions, incorrectly.

This change causes us to not to try to phi of ops such expressions.
We determine safety by seeing if they depend on a phi node in our
block.

This is not perfect, we can do a bit better, but this should be a
"correctness start" that we can then improve.  It also requires a
bunch of caching that i'll eventually like to eliminate.

The right solution, longer term, to the simplifier issues, is to make
the query interface for the instruction simplifier/constant folder
have the flags we need, so that we can keep most things going, but
turn off the possibly-invalid parts (threading through phis, etc).
This is an issue in another wrong code bug as well.

Disable 64bit file position on old 32 bit Androids.

This is needed for building LLVM on Android with new NDK (newer
than r15c) and API level < 24. Android C library (Bionic) didn't have
support for 64 bit file position until Android N.
