Detailed description:
|
|
I've implemented functions ALOb(), ObAL(), YbAL(),
|
|
ALXb() and eAXXv() from dis_groups.cc.
|
|
|
|
I've also changed dis_decode.cc to print cmpsd if code
|
|
is 32 bits and cmpsw if code is 16 bits. The same with
|
|
stosd, lodsd and scasd.
|
|
|
|
Patch was created with:
