10 years agosplit delinearization pass in 3 steps
Sebastian Pop [Wed, 7 May 2014 18:01:20 +0000 (18:01 +0000)]
split delinearization pass in 3 steps

To compute the dimensions of the array in a unique way, we split the
delinearization analysis in three steps:

- find parametric terms in all memory access functions
- compute the array dimensions from the set of terms
- compute the delinearized access functions for each dimension

The first step is executed on all the memory access functions such that we
gather all the patterns in which an array is accessed. The second step reduces
all this information in a unique description of the sizes of the array. The
third step is delinearizing each memory access function following the common
description of the shape of the array computed in step 2.

This rewrite of the delinearization pass also solves a problem we had with the
previous implementation: because the previous algorithm was by induction on the
structure of the SCEV, it would not correctly recognize the shape of the array
when the memory access was not following the nesting of the loops: for example,
see polly/test/ScopInfo/multidim_only_ivs_3d_reverse.ll

; void foo(long n, long m, long o, double A[n][m][o]) {
;
;   for (long i = 0; i < n; i++)
;     for (long j = 0; j < m; j++)
;       for (long k = 0; k < o; k++)
;         A[i][k][j] = 1.0;

Starting with this patch we no longer delinearize access functions that do not
contain parameters, for example in test/Analysis/DependenceAnalysis/GCD.ll

;;  for (long int i = 0; i < 100; i++)
;;    for (long int j = 0; j < 100; j++) {
;;      A[2*i - 4*j] = i;
;;      *B++ = A[6*i + 8*j];

these accesses will not be delinearized as the upper bound of the loops are
constants, and their access functions do not contain SCEVUnknown parameters.

  v0 = load v2i32
  v1 = BITCAST v2i32 v0 to v4i16
       store v4i16 v2

In big endian mode every memory access has an implicit byte swap. LDR and
STR do a 64-bit byte swap, whereas LD1/ST1 do a byte swap per lane - that
is, they treat the vector as a sequence of elements to be byte-swapped.
The two pairs of instructions are fundamentally incompatible. We've decided
to use LD1/ST1 only to simplify compiler implementation.

LD1/ST1 perform the equivalent of a sequence of LDR/STR + REV. This makes
the original code sequence:  v0 = load v2i32

  v1 = REV v2i32                  (implicit)
  v2 = BITCAST v2i32 v1 to v4i16
  v3 = REV v4i16 v2               (implicit)
       store v4i16 v3

But this is now broken - the value stored is different to the value loaded
due to lane reordering. To fix this, on every BITCAST we must perform two
other REVs:

  v0 = load v2i32
  v1 = REV v2i32                  (implicit)
  v2 = REV v2i32
  v3 = BITCAST v2i32 v2 to v4i16
  v4 = REV v4i16
  v5 = REV v4i16 v4               (implicit)
       store v4i16 v5

This means an extra two instructions, but actually in most cases the two REV
instructions can be combined into one. For example:
  (REV64_2s (REV64_4h X)) === (REV32_4h X)

There is also no 128-bit REV instruction. This must be synthesized with an
EXT instruction.

Most bitconverts require some sort of conversion. The only exceptions are:
  a) Identity conversions -  vNfX <-> vNiX
  b) Single-lane-to-scalar - v1fX <-> fX or v1iX <-> iX

Even though there are hundreds of changed lines, I have a fairly high confidence
that they are somewhat correct. The changes to add two REV instructions per
bitcast were pretty mechanical, and once I'd done that I threw the resulting
.td at a script I wrote which combined the two REVs together (and added
an EXT instruction, for f128) based on an instruction description I gave it.

This was much less prone to error than doing it all manually, plus my brain
would not just have melted but would have vapourised.

Summary:
The overall idea is to chop the Predicates list into subsets that are
usually overridden independently. This allows subclasses to partially
override the predicates of their superclasses without having to re-add all
the existing predicates.

This patch starts the process by moving HasStdEnc into a new
EncodingPredicates list and almost everything else into
AdditionalPredicates.

It has revealed a couple likely bugs where 'let Predicates' has removed
the HasStdEnc predicate.

No functional change (confirmed by diffing tablegen-erated files).

Do not make -pass-remarks additive.

Summary:
When I initially introduced -pass-remarks, I thought it would be a
neat idea to make it additive. So, if one used it as:

$ llc -pass-remarks=inliner --pass-remarks=loop.*

the compiler would build the regular expression '(inliner)|(loop.*)'.

The more I think about it, the more I regret it. This is not how
other flags work. The standard semantics are right-to-left overrides.

This is how clang interprets -Rpass. And I think the two should be
compatible in this respect.

Andrea Di Biagio [Tue, 6 May 2014 17:09:03 +0000 (17:09 +0000)]
[X86] Improve the lowering of BITCAST dag nodes from type f64 to type v2i32 (and vice versa).

Before this patch, the backend always emitted a store+load sequence to
bitconvert from f64 to i64 the input operand of a ISD::BITCAST dag node that
performed a bitconvert from type MVT::f64 to type MVT::v2i32. The resulting
i64 node was then used to build a v2i32 vector.

With this patch, the backend now produces a cheaper SCALAR_TO_VECTOR from
MVT::f64 to MVT::v2f64. That SCALAR_TO_VECTOR is then followed by a "free"
bitcast to type MVT::v4i32. The elements of the resulting
v4i32 are then extracted to build a v2i32 vector (which is illegal and
therefore promoted to MVT::v2i64).

This is in general cheaper than emitting a stack store+load sequence
to bitconvert the operand from type f64 to type i64.
