C30 User’s Guide
built-in function 'identifier' declared as non-function
The specified function has the same name as a built-in function, yet is declared as
something other than a function.
C
C++ style comments are not allowed in ISO C89
Use C style comments '/*' and '*/' instead of C++ style comments '//'.
call-clobbered register used for global register variable
Choose a register that is normally saved and restored by function calls (W8-W13), so
that library routines will not clobber it.
cannot inline function 'main'
The function 'main' is declared with the inline attribute. This is not supported, since
main must be called from the C start-up code, which is compiled separately.
can't inline call to 'identifier' called from here
The compiler was unable to inline the call to the specified function.
case value 'n' not in enumerated type
The controlling expression of a switch statement is an enumeration type, yet a case
expression has the value n, which does not correspond to any of the enumeration
values.
case value 'value' not in enumerated type 'name'
'value' is an extra switch case that is not an element of the enumerated type 'name'.
cast does not match function type
The return type of a function is cast to a type that does not match the function's type.
cast from pointer to integer of different size
A pointer is cast to an integer that is not 16-bits wide.
cast increases required alignment of target type
When compiling with the -Wcast-align command-line option, the compiler verifies
that casts do not increase the required alignment of the target type. For example, this
warning message will be given if a pointer to char is cast as a pointer to int, since the
aligned for char (byte alignment) is less than the alignment requirement for int (word
alignment).
character constant too long
Character constants must not be too long.
comma at end of enumerator list
Unnecessary comma at the end of the enumerator list.
comma operator in operand of #if
Not expecting a comma operator in the #if directive.
comparing floating point with == or != is unsafe
Floating-point values can be approximations to infinitely precise real numbers. Instead
of testing for equality, use relational operators to see whether the two values have
ranges that overlap.
comparison between pointer and integer
A pointer type is being compared to an integer type.
