Otherwise we'll end with random cyclic deps between libraries due to this.

Fix PR6047

Nodes that had children outside of the post dominator tree (infinite loops)

in the tree.

Improve llvm.dbg.declare intrinsic by referring directly to the storage in its first argument, via function-local metadata (instead of via a bitcast).
This patch also cleans up code that expects there to be a bitcast in the first argument and testcases that call llvm.dbg.declare.

Improve llvm.dbg.declare intrinsic by referring directly to the storage in its first argument, via function-local metadata (instead of via a bitcast).
This patch also cleans up code that expects there to be a bitcast in the first argument and testcases that call llvm.dbg.declare.

Remove DEBUG_DECLARE, looks like we don't need it.
Also, DEBUG_VALUE has side effects.

Fix cmp emission on msp430: we definitely should turn stuff like
"icmp lhs, rhs" into "cmp rhs, lhs". This should fix PR5979.

Added 16-bit Thumb Load/Store immediate instructions with encoding bits so that

add virtual methods to get the start/end of a MCParsedAsmOperand,
the default implementation returns "unknown".

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93470 91177308-0d34-0410-b5e6-96231b3b80d8

Split the TargetAsmParser "ParseInstruction" interface in half:
the new ParseInstruction method just parses and returns a list of
target operands.  A new MatchInstruction interface is used to
turn the operand list into an MCInst.

This requires new/deleting all the operands, but it also gives
targets the ability to use polymorphic operands if they want to.
