I have a pass that modifies my machine dependent instructions and I have
ran into a situation where I want to remove all instructions that an
instruction is dependent on when I remove an instruction.
Is there a way to do this using the API calls?
For example, I have a sequence of instructions
a = b + c
d = c * c
store d, *a
load e, *a
f = e + d
since the store and load are pointless I want to turn them into a simple
move turning the code into
a = b + c
d = c * c
tmp = d
e = tmp
f = e + d
however I also want to remove the `a = b + c` instruction.
Any idea's?
Thanks,
