Hello, I am fighting with 16f690 processor. I have two INT variables and add
them together. SDCC generates following code:
; .line 349; "main.c" gYfilter = gYfilter + gYrotation;
BANKSEL _gYrotation
MOVF _gYrotation,W
BANKSEL _gYfilter
ADDWF _gYfilter,F
BANKSEL _gYrotation
MOVF (_gYrotation + 1),W
BTFSC STATUS,0
INCF (_gYrotation + 1),W
BTFSC STATUS,2
GOTO _00004_DS_
BANKSEL _gYfilter
ADDWF (_gYfilter + 1),F
_00004_DS_:
Is it correct ? if both low bytes are 0x00, first btfsc skips and the second
skips as well. so there will be no addition at all.
Or did I miss something ?
Thank you,
Vasek
