integers in that the code to handle split alloca-wide integer loads or
stores doesn't come first. It should, for the same reasons as with
integers, and the PR attests to that. Also had to fix a busted assert in
that this test case also covers.

Instead of recomputing relative pointer information just prior to fusing,
cache this information (which also needs to be computed during the
candidate-pair selection process). This cuts down on the total number of
SE queries made, and also is a necessary intermediate step on the road toward
including shuffle costs in the pair selection procedure.

No functionality change is intended.

Stop propagating the FlipMemInputs variable into the routines that
create the replacement instructions. Instead, just flip the arguments
of those routines. This allows for some associated cleanup (not all
of which is done here). No functionality change is intended.

the MachineInstr MayLoad/MayLoad flags are based on the tablegen implementation.
For inline assembly, however, we need to compute these based on the constraints.

Revert r166929 as this is no longer needed, but leave the test case in place.

is unreliable, and thus ignored). No functionality change is intended.

Speedup SciMark by 1%

This patch expands FSQRT for floating point vector types when altivec is
used.

llvm-svn: 167034

The attached patch adds eValueTypeVector to lldb_private::Value.  The nested struct Vector is patterned after RegisterValue::m_data.buffer.  This change to Value allows ClangExpressionDeclMap::LookupDecl to return vector register data for consumption by InterpreterStackFrame::ResolveValue.  Note that ResolveValue was tweaked slightly to allocate enough memory for vector registers.
 
An immediate result of this patch is that "expr $xmm0" generates the same results on Linux as on the Mac, which is good enough for TestRegisters.py.  In addition, the log of m_memory.PrintData(data_region.m_base, data_region.m_extent) shows that the register content has been resolved successfully.  On the other hand, the output is glaringly empty:
    runCmd: expr $xmm0
    output: (unsigned char __attribute__((ext_vector_type(16)))) $0 = {}
    Expecting sub string: vector_type

This fixes Clang :: CodeGen/complex-builtints.c on PowerPC.

llvm-svn: 167013

When the switch-to-lookup tables transform landed in SimplifyCFG, it
was pointed out that this could be inappropriate for some targets.
Since there was no way at the time for the pass to know anything about
the target, an awkward reverse-transform was added in CodeGenPrepare
that turned lookup tables back into switches for some targets.

This patch uses the new TargetTransformInfo to determine if a
switch should be transformed, and removes
CodeGenPrepare::ConvertLoadToSwitch.
