[LLVMdev] How to locate the start if an address mode in an X86 MachineInstr?
...imizations on X86 instructions, which would require identifying memory reference instructions.
In the X86 back end instructions, memory addresses consist of a set of five operands. The offset to the start of the five operands depends on the format of the instruction. For instance, the instructions ADC32rm, ADD32rm, AND32rm, ANDN32rm, CMOVA32rm, CMOVAE32rm, CMOVB32rm, et al. all have a 32 bit memory address set starting at operand 2.
There does not seem to be any way to obtain the offset to the start of a memory reference in an X86 MachineInstr.
Tablegen code is able to determine the offset when it...
