Error and Warning Messages
(764) mismatched comparison
A comparison is being made between a variable or expression and a constant value which is not in
the range of possible values for that expression, e.g.:
(765) degenerate unsigned comparison
There is a comparison of an unsigned value with zero, which will always be true or false, e.g.:
will always be true, because an unsigned value can never be less than zero.
(766) degenerate signed comparison
There is a comparison of a signed value with the most negative value possible for this type, such
that the comparison will always be true or false, e.g.:
will always be true, because an 8 bit signed char has a maximum negative value of -128.
(768) constant relational expression
There is a relational expression that will always be true or false. This may be because e.g. you are
comparing an unsigned number with a negative value, or comparing a variable with a value greater
than the largest number it can represent, e.g.:
(769) no space for macro definition
The assembler has run out of memory.
unsigned char c;
if(c > 300)
unsigned char c;
if(c >= 0)
char c;
if(c >= -128)
unsigned int a;
if(a == -10)
close();
b = 9;
/* if a is unsigned, how can it be -10? */
/* woops -- how can this be true? */
