gcc -pedantic does not warn about bitfield overflow.
For example:
struct test
{
signed int a:16;
signed int b:8;
int pad:8;
};
struct test c = {32768, 256, 0};
signed short int d = 32768;
signed char e = 256;
compile with gcc -pedantic
and it will warn aboud d and e:
t.c:10: warning: overflow in implicit constant conversion
t.c:11: warning: overflow in implicit constant conversion
but nothing about the initialization of struct test c;
IMHO it should warn about those too.
>How-To-Repeat:
compile the example with gcc -pedantic and see that there are no
warnings generated for struc test c
