Floating-Point instructions support #12

Closed arkup closed 5 years ago

arkup commented 5 years ago

Hi, would be great if you could implement floating-point instructions support..seems only IDA, objdump can disasm the FPU instructions e.g.

10 60 02 D1     efscfsi   r3, r0
13 a3 02 c9     efsdiv  r29,r3,r0

even the NSA baby (Ghidra 9.0.1) failed on this :(
