bit operator == in PCM v3.207
PostPosted: Tue Aug 24, 2004 12:35 am     Reply with quote
Hi to all,

I've found a problem with the "optimized" == operator for bit variables in v3.207:

EinAus_b1 bit adress is ".3"....normally..and as you can see in the lst-file, the "==" Operator asks for bit adress .0

.lst file:

Code:

....................    if(EinAus_b1 == 0) 
1317:  BTFSC  49.0     <--- ???
1318:  GOTO   31D
....................    { 
....................       delay_us(2); 
1319:  NOP
131A:  NOP
131B:  NOP
131C:  NOP
....................    } 
....................   
....................    if(!EinAus_b1) 
131D:  BTFSC  49.3  <--- ok
131E:  GOTO   323
....................    { 
....................       delay_us(2); 
131F:  NOP
1320:  NOP
1321:  NOP
1322:  NOP
....................    }

A very annoying bug and it will effect many programs!

This same bug in v3.207 was reported 5 days ago in this thread.

yes, this will affect many many programs and I can't believe the dilettantish testing of the "optimized" == bit operation.
