Chad Rosier 07a4cb9382 [avx] Adjust the VINSERTF128rm pattern to allow for unaligned loads.
This results in things such as

	vmovups	16(%rdi), %xmm0
	vinsertf128	$1, %xmm0, %ymm0, %ymm0

to be combined to

    vinsertf128	$1, 16(%rdi), %ymm0, %ymm0

Bill Wendling 7315c4b9cd It's possible to have a constant expression who's size is quite big (e.g.,
i128). In that case, we may not be able to print out the MCExpr as an
expression. For instance, we could have an MCExpr like this:

    0xBEEF0000BEEF0000 | (0xBEEF0000BEEF0000 << 64)

The MCExpr printer handles sizes up to 64-bits, but this expression would
require 128-bits. In this situation, try to evaluate the constant expression and
emit that as the value into 64-bit chunks.

Craig Topper b34d96c614 Remove code that prevented lowering shuffles if they are used by load and themselves used by a extract_vector_elt. This was done to allow the DAG combiner to collapse to a single element load. Unfortunately, sometimes the extract_vector_elt would disappear before DAG combine could do the transformation leaving a vector_shuffle that isel couldn't handle. New code lets the shuffle be converted to a target specific node, but then adds a combine routine that can convert target specific nodes back to vector_shuffles if the folding criteria are met.

Eric Christopher 60e01c560a Do everything up to generating code to try to get a register for
a variable. The previous code would break the debug info changing
code invariant. This will regress debug info for arguments where
we elide the alloca created.

Chris Lattner 0a2ac90525 Fix two bugpoint bugs:
1) opt is not usually in the same path as the target program. Even for
the bugpoint as a standalone app, it should be more portable to search
in PATH, isn't it?
2) bugpoint driver accounts opt plugins, but does not list them in the
final output command.

Preston Gurd 48ccc4df0b This patch adds X86 instruction itineraries for non-pseudo opcodes in
X86InstrCompiler.td.
 
It also adds –mcpu-generic to the legalize-shift-64.ll test so the test
will pass if run on an Intel Atom CPU, which would otherwise
produce an instruction schedule which differs from that which the test expects.

Suggestions on still better / more consistent formatting would be
welcome. I'm actually tempted to use a macro to define all of the

Bill Wendling 23f8c4a50c Check if we can handle the arguments of a call (and therefore the call) in
fast-isel before emitting code. If the program bails after code was emitted,
then it could lead to the stack being adjusted more than once (two
CALLSEQ_BEGINs emitted) but being adjuste back only once after the call. This
leads to general badness and gnashing of teeth.

Jim Grosbach 905686a82a ARM ldm/stm register lists can be out of order.
It's not a good style idea, as the registers will be laid down in memory in
numerical order, not the order they're in the list, but it's legal. vldm/vstm
are stricter.
