Summary0002304: E-ACSL: compilation fail: generated functions doesn't have static inline attributes
DescriptionThe 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' collect2: error: ld returned 1 exit status
