Expressions Within Enum Broken

[djulien 0]

Bug description:

BoostC is not correctly handling expressions within enum.

 

Example code:

#include <system.h>

enum { Constant1 = 0x1A0 };
enum { Constant2 = Constant1 + 1*1 };

int debug @0x70;

void main(void)
{
debug = Constant1; //should be 0x1A0; this one works
debug = Constant2; //should be 0x1A1, actually is 0x0A1
}

 

The code that is being generated is:

MOVLW 0xA0
MOVWF gbl_debug
MOVLW 0x01		;//this is correct
MOVWF gbl_debug+D'1'
MOVLW 0xA1
MOVWF gbl_debug
CLRF gbl_debug+D'1'  ;// this is wrong
RETURN

 

 

Expected behavior:

Compiler should generate the correct opcodes to assign the value.

 

Is the problem 100% reproduceable:

yes

 

Compiler:

BoostC

 

Compiler version:

7.1+

 

Target device:

PIC16F1827, etc.

 

OS:

Windows XP
