I am running into a problem when I turn on post-RA scheduler with mode "ANTIDEP_CRITICAL" for mips. I'd appreciate if someone could explain what is going wrong here. This is the basic block before post RA scheduling (at PostRASchedulerList.cpp:322): *(gdb) #3 0x0000000000ed3d26 in runOnMachineFunction (this=0x20aa470, Fn=...) at lib/CodeGen/PostRASchedulerList.cpp:322 3...

All these passes are pretty sensitive to correct register liveness information.

hi, I have few question about breaking anti-dependence of postRAScheduler in LLVM. when I use command line "clang -target arm -mcpu=cortex-a8 -O2 -integrated-as -c test.c -o test.o" and get objdump file as follows: ldrr1, [r0,#16]----(1 str r1, [r0,#32]----(2 ldr r1, [r0,#12]----(3 str r1, [r0,#36]----(4 ldr r1, [r0,#08]----(5 str r1, [r0,#40]----(6 However, I expect that instruction
