Cameron Zwarich 8e7dc068c9 Make repairIntervalsInRange() more robust. There are now no longer any liveness-
related failures when running 'make check' without LiveVariables with the
verifier enabled. Some of the remaining failures elsewhere may still be fallout
from incorrect updating of LiveIntervals or the few missing cases left in the
two-address pass.

Arnold Schwaighofer 3f9568e921 DAGCombiner: Fold pointless truncate, bitcast, buildvector series
(2xi32) (truncate ((2xi64) bitcast (buildvector i32 a, i32 x, i32 b, i32 y)))
can be folded into a (2xi32) (buildvector i32 a, i32 b).

Such a DAG would cause uneccessary vdup instructions followed by vmovn
instructions.

We generate this code on ARM NEON for a setcc olt, 2xf64, 2xf64. For example, in
the vectorized version of the code below.

double A[N];
double B[N];

void test_double_compare_to_double() {
  int i;
  for(i=0;i<N;i++)
    A[i] = (double)(A[i] < B[i]);
}

Daniel Malea c6a70063cb Fix invalid TestBitfields case (thanks Filipe!), and xfail one case due to GCC compiler bug.
Turns out unnamed bit fields should not be accessed ever in C (C99 section 4.7.8) or C++
(C++11 section 9.6). 

Unrelated to the above, this commit marks TestBitfields as expected-to-fail with GCC as 4.7
has problems with padding... the size of the struct with a uint32_t member is reported as 12
when GCC is used. Clang emits correct code.

Parts of this patch prepared by Filipe Cabecinhas!

Jakob Stoklund Olesen 623d8329e3 Use LiveRangeUpdater instead of mergeIntervalRanges.
Performance is the same, but LiveRangeUpdater has a more flexible
interface.

llvm-svn: 175645
2013-02-20 18:18:15 +00:00
Jakob Stoklund Olesen 521c708e6e Add a LiveRangeUpdater class.
Adding new segments to large LiveIntervals can be expensive because the
LiveRange objects after the insertion point may need to be moved left or
right. This can cause quadratic behavior when adding a large number of
segments to a live range.

The LiveRangeUpdater class allows the LIveInterval to be in a temporary
invalid state while segments are being added. It maintains an internal
gap in the LiveInterval when it is shrinking, and it has a spill area
for new segments when the LiveInterval is growing.

The behavior is similar to the existing mergeIntervalRanges() function,
except it allocates less memory for the spill area, and the algorithm is
turned inside out so the loop is driven by the clients.

- When extloading from a vector with non-byte-addressable element, e.g.

  fix the case where the element type is not byte-addressable by loading
  all bytes, bit-extracting/packing each element.
