V
__VA_ARGS__ can only appear in the expansion of a C99 variadic macro
The predefined macro __VA_ARGS should be used in the substitution part of a macro
definition using ellipses.
value computed is not used
A value computed is not used.
variable name declared inline
The keyword inline should be used with functions only.
variable %s might be clobbered by longjmp or vfork
A non-volatile automatic variable might be changed by a call to longjmp. These
warnings are possible only in optimizing compilation.
volatile register variables dont work as you might wish
Passing a variable as an argument could transfer the variable to a different register
(w0-w7) than the one specified (if not w0-w7) for argument transmission. Or the
compiler may issue an instruction that is not suitable for the specified register and may
need to temporarily move the value to another place. These are only issues if the
specified register is modified asynchronously (i.e., though an ISR).
W
-Wformat-extra-args ignored without -Wformat
-Wformat must be specified to use -Wformat-extra-args.
-Wformat-nonliteral ignored without -Wformat
-Wformat must be specified to use -Wformat-nonliteral.
-Wformat-security ignored without -Wformat
-Wformat must be specified to use -Wformat-security.
-Wformat-y2k ignored without -Wformat
-Wformat must be specified to use.
-Wid-clash-LEN is no longer supported
The option -Wid-clash-LEN is no longer supported.
-Wmissing-format-attribute ignored without -Wformat
-Wformat must be specified to use -Wmissing-format-attribute.
-Wuninitialized is not supported without -O
Optimization must be on to use the -Wuninitialized option.
identifier was declared extern and later static
The specified identifier was previously declared extern and is now being declared as
static.
identifier was declared implicitly extern and later static
The specified identifier was previously declared implicitly extern and is now being
declared as static.
identifier was previously implicitly declared to return int
There is a mismatch against the previous implicit declaration.
