EQV, IMP, XOR

[blackborn66]

these operators are all implemented (no compile or link error)
but all results are FALSE (no pun intended ;)
version 0.8.2 and 0.8.3 show the same

the behaviour seems to be different for constant expressions and expressions depending on variables

[gooofy]

actually, these operators are all covered in the test suite, e.g.

https://github.com/gooofy/aqb/blob/master/tests/opint.bas

at least to some extend - do you have an example for what is not working for you?

[blackborn66]

As far as I can see, it isn't working for boolean constants.
Then the return is always FALSE (no pun intended ;)

DIM AS BOOLEAN b0, b1
b0 = TRUE
b1 = FALSE

TRACE "XOR"; " "; b0 XOR b0; " "; TRUE XOR TRUE
TRACE "XOR"; " "; b1 XOR b1; " "; FALSE XOR FALSE
TRACE "XOR"; " "; b0 XOR b1; " "; TRUE XOR FALSE
TRACE "XOR"; " "; b1 XOR b0; " "; FALSE XOR TRUE

TRACE "EQV"; " "; b0 EQV b0; " "; TRUE EQV TRUE
TRACE "EQV"; " "; b1 EQV b1; " "; FALSE EQV FALSE
TRACE "EQV"; " "; b0 EQV b1; " "; TRUE EQV FALSE
TRACE "EQV"; " "; b1 EQV b0; " "; FALSE EQV TRUE

TRACE "IMP"; " "; b0 IMP b0; " "; TRUE IMP TRUE
TRACE "IMP"; " "; b1 IMP b1; " "; FALSE IMP FALSE
TRACE "IMP"; " "; b0 IMP b1; " "; TRUE IMP FALSE
TRACE "IMP"; " "; b1 IMP b0; " "; FALSE IMP TRUE
