Ark Linux Dockyard (Linux 2.4.21pre5, glibc 2.3.2)
>Description:
The following code used to work with older gcc versions, doesn't work with almost-3.3 anymore:
static unsigned char test[1024];
int main(int argc, char **argv)
{
__asm__ __volatile__ ("
call test");
}
Changing it into either
static unsigned char test[1024];
int main(int argc, char **argv)
{
__asm__ __volatile__ (" \
call test");
}
or
static unsigned char test[1024];
int main(int argc, char **argv)
{
__asm__ __volatile__ ("call test");
}
Works.
Intentional change, or bug?
>How-To-Repeat:
Try to compile the code above.
Results with gcc 3.3:
test.c:4:31: missing terminating " character
test.c: In function `main':
test.c:5: error: syntax error before "call"
test.c:5:34: missing terminating " character
