Flesh out the options supported for the instruction. Shuffle tests a bit and
add entries for the rest of the options. Add an alias to handle the default
operand of "sy".

llvm-svn: 135107

Add a target-indepedent entry to MCInstrDesc to describe the encoded size of an opcode.  Switch ARM over to using that rather than its own special MCInstrDesc bits.

llvm-svn: 135106

The frameless unwind stack has a special encoding, the algorithm for which is in
"permuteEncode".

llvm-svn: 135103

Add range checking and testing for parsing and encoding of DBG instruction.

general version of X86ISD::ANDNP also opened the room for a little bit
of refactoring.

it's later selected to a ANDNPD/ANDNPS instruction instead of the PANDN
instruction. Rename it.

Combine redundant base classes and such. No indended functional change.

Make sure we don't combine a large displacement and a frame index in the same addressing mode on x86-64.  It can overflow, leading to a crash/miscompile.

They're all Thumb2 only, not just some of them. More refactoring cleanup
coming.

llvm-svn: 135081

Some pysical registers create split solutions that would spill anywhere.
They should not even be considered in future multi-way global splits.

This does not affect code generation (yet).

llvm-svn: 135080

Refactor out checking for displacements on x86-64 addressing modes.  No functionality change.  Refactoring in preparation for an additional safety check in FoldOffsetIntoAddress.

Part of <rdar://problem/9763308>.

This is in preparation of supporting multiple global split candidates in
a single live range split operation.

The immediate is of limited range and the operand type should reflect that.

It's not safe to fold (fptrunc (sqrt (fpext x))) to (sqrtf x) if there is another use of sqrt. rdar://9763193

Catch potential cascading errors on a malformed so_reg operand and bail after
the first error.

Add some tests for the diagnostics we do want.

Now works for parsing register shifted register and register shifted
immediate arithmetic instructions, including the 'rrx' rotate with extend.

llvm-svn: 135047

Update the debug output interface for MCParsedAsmOperand to have a print()
method which takes an output stream argument, an << operator which invokes
the print method using the given stream, and a dump() method which prints
the operand to the dbgs() stream. This makes the interface more consistent
with the rest of LLVM, and more convenient to use at the debugger command
line.
