Chris Lattner 600dee4aae * Convert to be a MachineFunctionPass instance ... * Use new FunctionFrameInfo object to manage stack slots instead of doing it directly * Adjust to new MRegisterInfo API * Don't take a TM as a ctor argument * Don't keep track of which callee saved registers are modified * Don't emit prolog/epilog code or spill/restore code for callee saved regs * Use new allocation_order_begin/end iterators to simplify dramatically the logic for picking registers to allocate * Machine PHI nodes can no longer contain constant arguments * Use a bitvector to keep track of registers used instead of a set * Fix problem where explicitly referenced registers would be added to regsused set and never removed git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@5196 91177308-0d34-0410-b5e6-96231b3b80d8		2002-12-28 20:42:14 +00:00
