Evan Cheng 71fa36ef12 - Fixed some priority calculation bugs that were causing bug 478. Among them: ... a predecessor appearing more than once in the operand list was counted as multiple predecessor; priority1 should be updated during scheduling; CycleBound was updated after the node is inserted into priority queue; one of the tie breaking condition was flipped. - Take into consideration of two address opcodes. If a predecessor is a def&use operand, it should have a higher priority. - Scheduler should also favor floaters, i.e. nodes that do not have real predecessors such as MOV32ri. - The scheduling fixes / tweaks fixed bug 478: .text .align 4 .globl _f _f: movl 4(%esp), %eax movl 8(%esp), %ecx movl %eax, %edx imull %ecx, %edx imull %eax, %eax imull %ecx, %ecx addl %eax, %ecx leal (%ecx,%edx,2), %eax ret It is also a slight performance win (1% - 3%) for most tests. llvm-svn: 26470		2006-03-02 21:38:29 +00:00
