Summary: Preprocessor doesn't support GNU extension?
Product: clang
Version: unspecified
Platform: PC
OS/Version: FreeBSD
Status: NEW
Severity: normal
Priority: P2
Component: preprocessor
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
Blocks: 3696
The following code doesn't get preprocessed by Clang properly:
#define fail(...) \
foo("Failed" , ## __VA_ARGS__, NULL)
int
main(int argc, char *argv[])
{
fail();
}
GCC does accept it and processes it as follows:
int
main(int argc, char *argv[])
{
foo("Failed", NULL);
}
