Here is a testcase for more problems:
[hjl@gnu-12 prev-gcc]$ cat /tmp/x.i
struct rtx_def;
typedef struct rtx_def *rtx;
extern int foo;
extern int bar;
extern int xxx;
int
test (void)
{
if (((rtx) 0 != (rtx) 0) && xxx ? foo : bar)
return 1;
else if ((foo & 0) && xxx)
return 2;
else if (foo & 0)
return 3;
else if (0 && xxx)
return 4;
else if (0)
return 5;
else
return 0;
}
[hjl@gnu-12 prev-gcc]$ ./xgcc -B./ -Wall -W -O2 -Werror -S /tmp/x.i
cc1: warnings being treated as errors
