Function never called
Function not void and does not return a value.
Info:
Interrupt level changed
Interrupts disabled during call to prevent re-entrancy.
Linker Warning: "%s" already defined in object "%s"; second definition ignored.
Linker Warning: Address and size of section "%s" in module "%s" exceeds maximum range for
this processor. The section will be ignored.
Linker Warning: The module "%s" doesn't have a valid chip id. The module will be considered
for the target chip "%s".
Linker Warning: The target chip "%s" of the imported module "%s" doesn't match the target chip
"%s" of the source.
Linker Warning: Unsupported relocation type in module "%s".
Memory not available at requested location.
Operator precedence rules may not be as intended, use() to clarify
Some combinations of operators are confusing to some programmers. This warning is issued
for expressions where adding() would help to clarify the meaning. For example:
if( x << n + 1 )
would be more universally understood when expressed:
if( x << (n + 1) )
Option may be wrong
Structure passed by value
Structures are usually passed by reference to a function. This warning is generated if the
structure is being passed by value. This warning is not generated if the structure is less than 5
bytes. For example:
void myfunct( mystruct s1 )
myfunct( s2 );
void myfunct( mystruct * s1 )
myfunct( &s2 );
void myfunct( mystruct & s1 )
// Pass by value - Warning
// Pass by reference - OK
// Pass by reference - OK
myfunct( s2 );
Undefined identifier
The specified identifier is being used but has never been defined. Check the spelling.
Unprotected call in a #INT_GLOBAL
The interrupt function defined as #INT_GLOBAL is intended to be assembly language or very
simple C code. This error indicates the linker detected code that violated the standard memory
allocation scheme. This may be caused when a C function is called from a #INT_GLOBAL
interrupt handler.
Unreachable code
Code included in the program is never executed. For example:
if(n==5)
goto do5;
goto exit;
if(n==20)
// No way to get to this line
return;
Unsigned variable is never less than zero
