Fix MergeConsecutiveStore for non-byte-sized memory accesses.

The bug showed up as a compile-time assertion failure:
  Assertion `NumBits >= MIN_INT_BITS && "bitwidth too small"' failed
when building msan tests on x86-64.

Prior to r236850, this bug was masked due to a bogus alignment check,
which also accidentally rejected non-byte-sized accesses. Afterwards,
an invalid ElementSizeBytes == 0 got further into the function, and
triggered the assertion failure.

It would probably be a good idea to allow it to handle merging stores
of unusual widths as well, but for now, to un-break it, I'm just
making the minimal fix.

[Fast-ISel] Don't mark the first use of a remat constant as killed.

When emitting something like 'add x, 1000' if we remat the 1000 then we should be able to
mark the vreg containing 1000 as killed.  Given that we go bottom up in fast-isel, a later
use of 1000 will be higher up in the BB and won't kill it, or be impacted by the lower kill.

However, rematerialised constant expressions aren't generated bottom up.  The local value save area
grows downwards.  This means that if you remat 2 constant expressions which both use 1000 then the
first will kill it, then the second, which is *lower* in the BB will read a killed register.

This is the case in the attached test where the 2 GEPs both need to generate 'add x, 6680' for the constant offset.

Note that this commit only makes kill flag generation conservative.  There's nothing else obviously wrong with
the local value save area growing downwards, and in fact it needs to for handling arbitrarily complex constant expressions.

However, it would be nice if there was a solution which would let us generate more accurate kill flags, or just kill flags completely.

TargetParser: FPU/ARCH/EXT parsing refactory - NFC

This new class in a global context contain arch-specific knowledge in order
to provide LLVM libraries, tools and projects with the ability to understand
the architectures. For now, only FPU, ARCH and ARCH extensions on ARM are

Current behaviour it to parse from free-text to enum values and back, so that
all users can share the same parser and codes. This simplifies a lot both the
ASM/Obj streamers in the back-end (where this came from), and the front-end
parsers for command line arguments (where this is going to be used next).

The previous implementation, using .def/.h includes is deprecated due to its
inflexibility to be built without the backend support and for being too
cumbersome. As more architectures join this scheme, and as more features of
such architectures are added (such as hardware features, type sizes, etc) into
a full blown TargetDescription class, having a set of classes is the most
sane implementation.

The ultimate goal of this refactor both LLVM's and Clang's target description
classes into one unique interface, so that we can de-duplicate and standardise
the descriptions, as well as make it available for other front-ends, tools,

The FPU parsing for command line options in Clang has been converted to use
this new library and a number of aliases were added for compatibility:
 * A bogus neon-vfpv3 alias (neon defaults to vfp3)
 * armv5/v6
 * {fp4/fp5}-{sp/dp}-d16

Next steps:
 * Port Clang's ARCH/EXT parsing to use this library.
 * Create a TableGen back-end to generate this information.
 * Run this TableGen process regardless of which back-ends are built.
 * Expose more information and rename it to TargetDescription.
 * Continue re-factoring Clang to use as much of it as possible.

Extend the statepoint intrinsic to allow statepoints to be marked as transitions from GC-aware code to code that is not GC-aware.

This extension offers the backend the opportunity to insert (somewhat) arbitrary code to manage the transition from GC-aware code to code that is not GC-aware and back.

In order to support the injection of transition code, this extension wraps the STATEPOINT ISD node generated by the usual lowering lowering with two additional nodes: GC_TRANSITION_START and GC_TRANSITION_END. The transition arguments that were passed passed to the intrinsic (if any) are lowered and provided as operands to these nodes and may be used by the backend during code generation.

Eventually, the lowering of the GC_TRANSITION_{START,END} nodes should be informed by the GC strategy in use for the function containing the intrinsic call; for now, these nodes are instead replaced with no-ops.

[X86] Teach 'getTargetShuffleMask' how to look through ISD::WrapperRIP when decoding a PSHUFB mask.

The function 'getTargetShuffleMask' already knows how to deal with PSHUFB nodes
where the mask node is a load from constant pool, and the constant pool node
is wrapped by a X86ISD::Wrapper node. This patch extends that logic by teaching
it how to also look through X86ISD::WrapperRIP.

This helps function combineX86ShufflesRecusively to combine more shuffle
sequences containing PSHUFB nodes if we are in RIPRel PIC mode.

Before this change, llc (with -relocation-model=pic -march=x86-64) was unable
to decode a pshufb where the mask was loaded from a constant pool. For example,
the no-op shuffle from test 'x86-fold-pshufb.ll' was not folded into its
operand, so instead of generating a single 'movaps' the backend always
generated a sub-optimal 'movdqa + pshufb' sequence.

Added test x86-fold-pshufb.ll.

Fix alignment checks in MergeConsecutiveStores.

1) check whether the alignment of the memory is sufficient for the
*merged* store or load to be efficient.

Not doing so can result in some ridiculously poor code generation, if
merging creates a vector operation which must be aligned but isn't.

2) DON'T check that the alignment of each load/store is equal. If
you're merging 2 4-byte stores, the first *might* have 8-byte

7 years agoYAML: Enable the YAMLParser tests.
Alex Lorenz [Thu, 7 May 2015 18:08:46 +0000 (18:08 +0000)]
YAML: Enable the YAMLParser tests.

This commit enables the tests located in test/YAMLParser directory.
Those tests were never actually enabled, as llvm-lit didn't pick up the
files with the 'data' extension. The commit renames those test files to files
with the 'test' extension so that llvm-lit would find them.

This commit also modifies yaml-bench so that it returns an error status
if an error occurred during parsing. It also adds the '-use-color'
command line option to yaml-bench (to make sure that file check matches
the error messages in the output stream).

This commit modifies some of the renamed tests so that they wouldn't
fail. It gets rid of XFAILs and uses the 'not' command instead for
some of the tests that have to fail during parsing. This commit
also adds some 'FIXME' comments to a couple of tests that are
supposed to fail but currently pass because of various bugs
in the implementation of the yaml parser.

Diego Novillo [Thu, 7 May 2015 17:22:06 +0000 (17:22 +0000)]
Fix information loss in branch probability computation.

This addresses PR 22718. When branch weights are too large, they were
being clamped to the range [1, MaxWeightForBB]. But this clamping is
only applied to edges that go outside the range, so it distorts the
relative branch probabilities.

This patch changes the weight calculation to scale every branch so the
relative probabilities are preserved. The scaling is done differently
now. First, all the branch weights are added up, and if the sum exceeds
32 bits, it computes an integer scale to bring all the weights within
the range.

The patch fixes an existing test that had slightly wrong branch
probabilities due to the previous clamping. It now gets branch weights
scaled accordingly.
