Assembly instrumentation: handle more instructions #282

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
On X86, almost any instruction can have a memory argument. At the moment we 
instrument only a minority of them.

We could use MCInstrInfo/MCRegisterInfo to guess instruction memory properties.

Attached (very hackish) patch almost passes ffmpeg.
- it passes TargetMachine through global var, just because
- mishandles movzbl and, in general, determines memory access size from the 
size of the other argument. It's wrong for a lot of instructions.

I may work on it some more later.
