create locations from loc + offset
This variant works for simple strings. However, it cannot handle even simple
macros:
format.c:1:18: warning: format ‘%d’ expects a matching ‘int’ argument
[-Wformat=]
#define FORMAT "%d"
^
format.c:8:24: warning: format ‘%d’ expects a matching ‘int’ argument
[-Wformat=]
__builtin_printf("a" FORMAT);
^
whereas Clang can:
format.c:7:20: warning: more '%' conversions than data arguments [-Wformat]
__builtin_printf(FORMAT);
^
format.c:1:18: note: expanded from macro 'FORMAT'
#define FORMAT "%d"
~^
format.c:8:25: warning: more '%' conversions than data arguments [-Wformat]
__builtin_printf("a" FORMAT);
^
format.c:1:18: note: expanded from macro 'FORMAT'
#define FORMAT "%d"
~^
