llvm dev - Jun 2009 - [LLVMdev] physical registers content/data print out

Hi 

I am using LLVM version 2.5. I am trying to build traces, using lli
-print-machineinstrs to print out the machine instructions. But I don't get
access to the physical registers values (e.g.  %R4=??). Is it possible to
print out this physical registers values? I'd tried to modify the
MachineInstr.cpp, but I can't find the right place/value.

 

I hope anybody can help me

-print-machineinstrs will print instructions after the codegen, not
traces. There is currently no way to obtain neither traces nor values
of registers. LLVM executes stuff on per-function basis, not per
instruction, also JIT does not model registers in any way.
