Craig Topper 004867312e [X86] Stop printing moves between VR64 and GR64 with 'movd' mnemonic. Use 'movq' instead.
This behavior existed to work with an old version of the gnu assembler on MacOS that only accepted this form. Newer versions of GNU assembler and the current LLVM derived version of the assembler on MacOS support movq as well.

Francis Visoiu Mistrih 25528d6de7 [CodeGen] Unify MBB reference format in both MIR and debug output
As part of the unification of the debug format and the MIR format, print
MBB references as '%bb.5'.

The MIR printer prints the IR name of a MBB only for block definitions.

Simon Pilgrim 9df7d08cb2 [X86][MMX] Fix folding of shift value loads to cover whole 64-bits
rL230225 made the assumption that only the lower 32-bits of an MMX register load is used as a shift value, when in fact the whole 64-bits are reloaded and treated as a i64 to determine the shift value.

This patch reverts rL230225 to ensure that the whole 64-bits of memory are folded and ensures that the upper 32-bit are zero'd for cases where the shift value has come from a scalar source.

Found during fuzz testing.

David Blaikie a79ac14fa6 [opaque pointer type] Add textual IR support for explicit type parameter to load instruction
Essentially the same as the GEP change in r230786.

A similar migration script can be used to update test cases, though a few more
test case improvements/changes were required this time around: (r229269-r229278)

import fileinput
import sys
import re

pat = re.compile(r"((?:=|:|^)\s*load (?:atomic )?(?:volatile )?(.*?))(| addrspace\(\d+\) *)\*($| *(?:%|@|null|undef|blockaddress|getelementptr|addrspacecast|bitcast|inttoptr|\[\[[a-zA-Z]|\{\{).*$)")

for line in sys.stdin:
  sys.stdout.write(re.sub(pat, r"\1, \2\3*\4", line))

Bruno Cardoso Lopes 7b6c1ec22d [X86][MMX] Remove widening experimental flag from MMX tests.
Turns out that after the past MMX commits, we don't need to rely on this
flag to get better codegen for MMX. Also update the tests to become
triple neutral.

Bruno Cardoso Lopes 1eb8376ca7 [X86][MMX] Fix test to reflect current codegen
This test failed in several buildbots, a bit unclear how that happen
since this was the previous behavior before r230248.

Bruno Cardoso Lopes f488e2ae69 [X86][MMX] Add MMX instructions to foldable tables
Teach the peephole optimizer to work with MMX instructions by adding
entries into the foldable tables. This covers folding opportunities not
handled during isel.

Bruno Cardoso Lopes ab9ae87623 [X86][MMX] Handle i32->mmx conversion using movd
Implement a BITCAST dag combine to transform i32->mmx conversion patterns
into a X86 specific node (MMX_MOVW2D) and guarantee that moves between
i32 and x86mmx are better handled, i.e., don't use store-load to do the
conversion..

Bruno Cardoso Lopes cc6089d2e0 [X86][MMX] Add several bitcast tests
Avoid regression in previously supported MMX code by adding different
combinations of tests which exercise MMX bitcasts. Small improvements
to these patterns should come next.
