when determining validity of matching constraint. Allow i1
types access to the GR8 reg class for x86.

Fixes PR10352 and rdar://9777108

llvm-svn: 135180

Consolidate the individual declarations together for ease of reference. This
mirrors the organization in X86, as well, so is good for consistency. No
functional change.

ldm/stm are the cannonical spellings for ldmia/stmia, so use them as such.
Update the parsing/encoding tests accordingly.

The ISB instruction takes an optional operand, just like DMB/DSB. Typically
only 'sy' is meaningful.

[VECTOR-SELECT]
During type legalization we often use the SIGN_EXTEND_INREG SDNode.
When this SDNode is legalized during the LegalizeVector phase, it is
scalarized because non-simple types are automatically marked to be expanded.
In this patch we add support for lowering SIGN_EXTEND_INREG manually.
This fixes CodeGen/X86/vec_sext.ll when running with the '-promote-elements'
flag.

TargetAsmInfo, which in turn pulls in TargetRegisterInfo, etc. :-( There are
other cases of violations, but this is probably the worst.

This patch is but one small step towards fixing this. 500 more steps to go. :-(

Don't emit a bit test if there is only one case the test can yield false. A simple SETNE is sufficient.

llvm-svn: 135126

Fix up assertion in r135018 so it doesn't trigger on 32-bit; when we're in 32-bit, it doesn't matter whether the operation overflows because the computed address is not wider than the immediate.

llvm-svn: 135120

Add instalias for default 'sy' option. Add tests.

llvm-svn: 135116

llvm-svn: 135112

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: 135109

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.

llvm-svn: 135087

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

llvm-svn: 135085

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

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>.

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

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.
