[InstCombine] When adding an Instruction and its Users to the worklist at the same time, make sure we put the Users in first. Then put in the instruction.

This way we ensure we immediately revisit the instruction and do any additional optimizations before visiting the users. Otherwise we might visit the users, then the instruction, then users again, then instruction again.

Do not translate rint into nearbyint, but truncate it like nearbyint.

A common way to implement nearbyint is by fiddling with the floating
point environment and calling rint. This is used at least by the BSD
libm and musl. As such, canonicalizing the latter to the former will
create infinite loops for libm and generally pessimize performance, at
least when the generic C versions are used.

This change preserves the rint in the libcall translation and also
handles the domain truncation logic, so that rint with float argument
will be reduced to rintf etc.

[mips][msa] Prevent output operand from commuting for dpadd_[su].df ins

Implementation of TargetInstrInfo::findCommutedOpIndices for MIPS target,
restricting commutativity to second and third operand only for
dpaadd_[su].df instructions therein.

Prior to this change, there were cases where the vector that is to be added
to the dot product of the other two could take a position other than the
first one in the instruction, generating false output in the destination
vector.

Such behavior has been noticed in the two functions generating v2i64 output
values so far. Other ones may exhibit such behavior as well, just not for
the vector operands which are present in the test at the moment.

Tests altered so that the function's first operand is a constant splat so
that it can be loaded with a ldi instruction, since that is the case in
which the erroneous instruction operand placement has occurred. We check
that the register which is present in the ldi instruction is placed as the
first operand in the corresponding dpadd instruction.

Max Kazantsev [Fri, 31 Mar 2017 12:05:30 +0000 (12:05 +0000)]
[ScalarEvolution] Re-enable Predicate implication from operations

The patch rL298481 was reverted due to crash on clang-with-lto-ubuntu build.
The reason of the crash was type mismatch between either a or b and RHS in the following situation:

  LHS = sext(a +nsw b) > RHS.

This is quite rare, but still possible situation. Normally we need to cast all {a, b, RHS} to their widest type.
But we try to avoid creation of new SCEV that are not constants to avoid initiating recursive analysis that
can take a lot of time and/or cache a bad value for iterations number. To deal with this, in this patch we
reject this case and will not try to analyze it if the type of sum doesn't match with the type of RHS. In this
situation we don't need to create any non-constant SCEVs.

This patch also adds an assertion to the method IsProvedViaContext so that we could fail on it and not
go further into range analysis etc (because in some situations these analyzes succeed even when the passed
arguments have wrong types, what should not normally happen).

The patch also contains a fix for a problem with too narrow scope of the analysis caused by wrong
usage of predicates in recursive invocations.

7 years ago[CodeGen] Pass SDAG an ORE, and replace FastISel stats with remarks.
Ahmed Bougacha [Thu, 30 Mar 2017 17:49:58 +0000 (17:49 +0000)]
[CodeGen] Pass SDAG an ORE, and replace FastISel stats with remarks.

In the long-term, we want to replace statistics with something
finer-grained that lets us gather per-function data.
Remarks are that replacement.

Create an ORE instance in SelectionDAGISel, and pass it to
SelectionDAG.

SelectionDAG was used so that we can emit remarks from all
SelectionDAG-related code, including TargetLowering and DAGCombiner.
This isn't used in the current patch but Adam tells me he's interested
for the fp-contract combines.

Use the ORE instance to emit FastISel failures as remarks (instead of
the mix of dbgs() dumps and statistics that we currently have).

Eventually, we want to have an API that tells us whether remarks are
enabled (http://llvm.org/PR32352) so that we don't emit expensive
remarks (in this case, dumping IR) when it's not needed.  For now, use
'isEnabled' as a crude replacement.

This does mean that the replacement for '-fast-isel-verbose' is now
'-pass-remarks-missed=isel'.  Additionally, clang users also need to
enable remark diagnostics, using '-Rpass-missed=isel'.

This also removes '-fast-isel-verbose2': there are no static statistics
that we want to only enable in asserts builds, so we can always use
the remarks regardless of the build type.

Revert "Make naming in Host.h in line with coding standards."

This reverts r299062, which caused build failures on Windows.
It also reverts the attempts to fix the windows builds in r299064 and r299065.
The introduction of namespace llvm::sys::detail makes MSVC, and seemingly also
mingw, complain about ambiguity with the existing namespace llvm::detail.
E.g.:
C:\b\slave\sanitizer-windows\llvm\include\llvm/Support/MathExtras.h(184): error C2872: 'detail': ambiguous symbol
C:\b\slave\sanitizer-windows\llvm\include\llvm/Support/PointerLikeTypeTraits.h(31): note: could be 'llvm::detail'
C:\b\slave\sanitizer-windows\llvm\include\llvm/Support/Host.h(80): note: or       'llvm::sys::detail'

In r299064 and r299065 I tried to fix these ambiguities, based on the errors
reported in the log files. It seems however that the build stops early when
this kind of error is encountered, and many build-then-fix-iterations on
Windows may be needed to fix this. Therefore reverting r299062 for now to
get the build working again on Windows.
