(758) constant conditional branch: possible use of "=" instead of "=="
There is an expression inside an if or other conditional construct, where a constant is being assigned
to a variable. This may mean you have inadvertently used an assignment = instead of a compare ==,
e.g.:
will assign the value 4 to a, then , as the value of the assignment is always true, the comparison can
be omitted and the assignment to b always made. Did you mean:
which checks to see if a is equal to 4.
(759) expression generates no code
This expression generates no output code. Check for things like leaving off the parentheses in a
function call, e.g.:
Some devices require that special function register need to be read to clear hardware flags. To
accommodate this, in some instances the code generator does produce code for a statement which
only consists of a variable ID. This may happen for variables which are qualified as volatile.
Typically the output code will read the variable, but not do anything with the value read.
(760) portion of expression has no effect
Part of this expression has no side effects, and no effect on the value of the expression, e.g.:
376
/* this can never be false;
if(a == 4)
int fred;
fred;
int a, b, c;
a = b,c; /* “b” has no effect,
int a, b;
/* this can never be false;
if(a = 4)
always perform the true statement */
b = 6;
b = 6;
always perform the true statement */
/* this is valid, but has no effect at all */
was that meant to be a comma? */
