| C statement placed wrong in the lst file... v5.95 & 5.94 |

C statement placed wrong in the lst file...
Small test c file and the generated lst file from version 5.95 and my old version 5.66.
In the latest 5.95 (and version 5.94 and maybe other) the c statement and generated assembler code are placed wrong.
Right: 5.66
Left: 5.95
Link to a pic.

Problem is random, some file look ok and other have the placement error...
Anyone see the same? |

The 'source line' placement, is only really for guidance. So it is deciding here
to put it after the generated code, instead of before. Not really important.
Why are you worried about this?. Sometimes the lines are miles away from
the actual assembler code.
Must admit it'd seem to make more logic to keep it at least roughly in
order, but it might actually give some quite interesting 'clues' about how
the optimiser approaches things. |

It have worked nice in my .66.
You cant compare file if the statement are placed random.
The included compare tools in the pcw compiler cant too.
Must hard to read in fast view when it is placed in random...
Try to remove all \n and space and other format guideline from a c file, most hard to read but it work:-) |

What PIC ? I made your .LST fragments into a source file and it works
fine with an 18F46K22. All addresses are in order:

I see the same on some file no problem and other have problem...
Test code and PIC.
| Code: |
//#include <18f26k22.h>
#include <12f1840.h>
#use delay(clock=8M,int)
#ID CHECKSUM_PROGRAM
#ID CHECKSUM
void StaticVar(){
int8 i8_Nostatic=0x10;
static int8 i8_Static=0x20;
I8_Nostatic=0x11;
i8_Static=0x21;
}
void Calc(){
const int8 MaxAD = 245;//ad res 0..255 but pot only get about 245 for max.
const int8 Decimal= MaxAD*0.5;//245*0,5=122 samme som at lægge 0.5 til.
const int16 StateStep=20;//max step
static int8 stateold=255;
int8 ad,state;
if (ad>MaxAD) {ad=MaxAD;}
state = (ad*StateStep+Decimal)/MaxAD;//245*0,5=122 samme som at lægge 0.5 til.
}
void main(void){
StaticVar();
Calc();
}

| When using the #ID CHECKSUM_PROGRAM then the problem is there! |

Question.. How can you have two #ID statements?. Makes no sense.
Presumably the second will override the first.
However it looks as if when you specify #ID CHECKSUM_PROGRAM, the
compiler is re-ordering the fie when it calculates the checksum. :( |

Right!
The c code file are for error testing only!
It was me reporting some of the bug fix for the 5.95 and one fix was the #ID statement for checksum. Therefore not a production file just for compiler testing. |
