Bug #: 53229
Summary: macro unwinder for preprocessing errors
Classification: Unclassified
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: preprocessor
AssignedTo: [email protected]
ReportedBy: [email protected]
struct x {
int i;
};
struct x x;
#define TEST(X) x.##X
void foo (void)
{
TEST(i) = 0;
}
manuel@gcc12:~$ ~/trunk/187148M/build/gcc/cc1 test.c
foo
test.c: In function ‘foo’:
test.c:10:1: error: pasting "." and "i" does not give a valid preprocessing
token
TEST(i) = 0;
^
manuel@gcc12:~$ clang test.c
test.c:10:3: error: pasting formed '.i', an invalid preprocessing token
TEST(i) = 0;
^
test.c:6:19: note: expanded from macro 'TEST'
#define TEST(X) x.##X
^
GCC should say:
test.c:6:19: error: pasting "." and "i" does not give a valid preprocessing
token (did you mean 'x.X'?)
#define TEST(X) x.##X
^
test.c:10:3: note: in expansion of macro 'TEST' requested here
TEST(i) = 0;
^
