Evan Cheng 620fd19798 Experimental scheduler change to schedule / coalesce the copies added for function livein's. Take 2008-03-10-RegAllocInfLoop.ll, the schedule looks like this after these copies are inserted: ... entry: 0x12049d0, LLVM BB @0x1201fd0, ID#0: Live Ins: %EAX %EDX %ECX %reg1031<def> = MOVPC32r 0 %reg1032<def> = ADD32ri %reg1031, <es:_GLOBAL_OFFSET_TABLE_>, %EFLAGS<imp-def> %reg1028<def> = MOV32rr %EAX %reg1029<def> = MOV32rr %EDX %reg1030<def> = MOV32rr %ECX %reg1027<def> = MOV8rm %reg0, 1, %reg0, 0, Mem:LD(1,1) [0x1201910 + 0] %reg1025<def> = MOV32rr %reg1029 %reg1026<def> = MOV32rr %reg1030 %reg1024<def> = MOV32rr %reg1028 The copies unnecessarily increase register pressure and it will end up requiring a physical register to be spilled. With -schedule-livein-copies: entry: 0x12049d0, LLVM BB @0x1201fa0, ID#0: Live Ins: %EAX %EDX %ECX %reg1031<def> = MOVPC32r 0 %reg1032<def> = ADD32ri %reg1031, <es:_GLOBAL_OFFSET_TABLE_>, %EFLAGS<imp-def> %reg1024<def> = MOV32rr %EAX %reg1025<def> = MOV32rr %EDX %reg1026<def> = MOV32rr %ECX %reg1027<def> = MOV8rm %reg0, 1, %reg0, 0, Mem:LD(1,1) [0x12018e0 + 0] Much better! llvm-svn: 48307		2008-03-12 22:19:41 +00:00
