Started cleaning up the ext_op code
Trying to get rid of the case and use a table like the main opcodes not sure how to handle epilog/prolog... maybe another table? git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@2951 8ced0084-cf51-0410-be5f-012b33b47a6e

/* NOTES BY HERMES:
|
||||
|
||||
LZ flag: original opcodes andf and andcf are swaped. Also "jzr" and "jnz" are swaped but now named 'jlz' and 'jlnz'
|
||||
As you can see it obtain the same result but now LZ=1 correctly
|
||||
|
||||
Added conditional instructions:
|
||||
|
||||
conditional names:
|
||||
|
||||
NZ -> NOT ZERO
|
||||
Z -> ZERO
|
||||
|
||||
NS -> NOT SIGN
|
||||
S -> SIGN
|
||||
|
||||
LZ -> LOGIC ZERO (only used with andcf-andf instructions?)
|
||||
LNZ -> LOGIC NOT ZERO
|
||||
|
||||
G -> GREATER
|
||||
LE-> LESS EQUAL
|
||||
|
||||
GE-> GREATER EQUAL
|
||||
L -> LESS
|
||||
|
||||
Examples:
|
||||
|

jnz, ifs, retlnz

/* NOTES BY HERMES:
|
||||
|
||||
LZ flag: original opcodes andf and andcf are swaped. Also "jzr" and "jnz" are swaped but now named 'jlz' and 'jlnz'
|
||||
As you can see it obtain the same result but now LZ=1 correctly
|
||||
|
||||
Added conditional instructions:
|
||||
|
||||
conditional names:
|
||||
|
||||
NZ -> NOT ZERO
|
||||
Z -> ZERO
|
||||
|
||||
NS -> NOT SIGN
|
||||
S -> SIGN
|
||||
|
||||
LZ -> LOGIC ZERO (only used with andcf-andf instructions?)
|
||||
LNZ -> LOGIC NOT ZERO
|
||||
|
||||
G -> GREATER
|
||||
LE-> LESS EQUAL
|
||||
|
||||
GE-> GREATER EQUAL
|
||||
L -> LESS
|
||||
|
||||
Examples:

jnz, ifs, retlnz
