the first source operand is tied to the destination operand.
This is to accurately model the corresponding instructions where the upper
bits are unmodified.

If HA can only partially fit into VFP registers, we add padding to make sure
HA will be on stack and later VFP CPRCs will be on stack as well.

later, '-L <dir>' is allowed, but rewrite these in the driver as '-L<dir>' to
maintain backward compatibility. The same is true for the -I option.

"~rc" via getpwnam() instead of doing tilde expansion and doing soft-link
dereferencing via realpath() - if we're pointing to a softlink, leave it
as-is.

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.

SE was being called during the instruction-fusion process (when the result
is unreliable, and thus ignored). No functionality change is intended.

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 = {}

This patch adds more support for vector type comparisons using altivec.
It adds correct support for v16i8, v8i16, v4i32, and v4f32 vector
types for comparison operators ==, !=, >, >=, <, and <=.
