Description :
The absence of static inline attributes forces optional dependencies to be strict. This leads to undefined reference errors during compilation.
Test (inline.c): extern int do_mmap(int *a);
static inline int test_extern(int *a) // Static inline { return do_mmap(a); }
int main(void) { return 0; }
GCC Run: $ gcc ./inline.c # There is no error about do_mmap $ echo $? 0
Generated Code (inline_generated.c): ... /*@ assigns \result, *a; assigns \result \from *a; assigns *a \from *a; */ int __gen_e_acsl_do_mmap(int *a); ... __inline static int test_extern(int a) { int tmp; /@ behavior pre_do_mmap: assigns tmp, *a; assigns tmp \from *a; assigns *a \from *a; / tmp = __gen_e_acsl_do_mmap(a); return tmp; } ... /@ assigns \result, *a; assigns \result \from *a; assigns *a \from *a; */ int __gen_e_acsl_do_mmap(int *a) // <== ERROR { int __retres; __retres = do_mmap(a); return __retres; }
GCC Run:
$ gcc ./inline_generated.c
/tmp/cczBUd0r.o: In function __gen_e_acsl_do_mmap': inline_generated.c:(.text+0x24): undefined reference to do_mmap'
