Duraid Madina e8fd25f5c5 * OK, after changing to use liveIn/liveOut instead of IDEFs, ... to avoid redundant mov out3=r44 type instructions, we need to tell the register allocator the truth about out? registers. FIXME: unfortunately, since the list of allocatable registers is immutable, we can't simply 'delete r127' from the allocation order, say, if 'out0' is used. The only correct thing we can do is have a linear order of regs: out7, out6 ... out2, out1, out0, r32, r33, r34 ... r126, r127 and slide a 'window' of 96 registers along this line, depending on how many of the out? regs a function actually uses. The only downside of this is that the out? registers will be allocated _first_, which makes the resulting assembly ugly. :( Note this in the README. Hope this gets fixed soon. :) (note the 3rd person speech there) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21252 91177308-0d34-0410-b5e6-96231b3b80d8		2005-04-12 18:42:59 +00:00
