Jakob Stoklund Olesen 3627a46293 Rewrite MachineInstr::addOperand() to avoid NumImplicitOps. 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		2011-09-29 00:40:51 +00:00
