| |
Hi Linus,
I just did a git pull on sparse and it produced a new and I believe bogus warning when trying to assign a value to a bit field member. The warning is:
warning: generating address of non-lvalue (1)
Below is an example program that triggers the warning when you run:
sparse sparse-test.c
Best regards,

--- sparse-test.c ---
int main(void) { struct { unsigned bit1:1; unsigned bit2:1; } bits = { 0, 0 };
bits.bit1 = 1; /* sparse warns here! */ bits.bit2 = 0; /* sparse warns here! */ return 0; } - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
