2011-09-29Rewrite MachineInstr::addOperand() to avoid NumImplicitOps.Jakob Stoklund Olesen
The function needs to scan the implicit operands anyway, so no performance is won by caching the number of implicit operands added to an instruction. This also fixes a bug when adding operands after an implicit operand has been added manually. The NumImplicitOps count wasn't kept up to date. MachineInstr::addOperand() will now consistently place all explicit operands before all the implicit operands, regardless of the order they are added. It is possible to change an MI opcode and add additional explicit operands. They will be inserted before any existing implicit operands. The only exception is inline asm instructions where operands are never reordered. This is because of a hack that marks explicit clobber regs on inline asm as <implicit-def> to please the fast register allocator. This hack can go away when InstrEmitter and FastIsel can add exact <dead> flags to physreg defs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@140744 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-28Have the SjLjEHPrepare pass do some more heavy lifting.Bill Wendling
Upon further review, most of the EH code should remain written at the IR level. The part which breaks SSA form is the dispatch table, so that part will be moved to the back-end. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@140730 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-28Check in a patch that has already been code reviewed by Owen that I'd ↵James Molloy
forgotten to commit. Build on previous patches to successfully distinguish between an M-series and A/R-series MSR and MRS instruction. These take different mask names and have a *slightly* different opcode format. Add decoder and disassembler tests. Improvement on the previous patch - successfully distinguish between valid v6m and v7m masks (one is a subset of the other). The patch had to be edited slightly to apply to ToT. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@140696 91177308-0d34-0410-b5e6-96231b3b80d8
