| Summary | 0002413: missing E-ACSL code when ignoring asm annotation |
| Description | Hi,
//////////////// asm.c
void func()
{
int i = 0;
int *ptr=&i;
/*@ assert \valid(ptr); */
*ptr = 0;
}
int main(int argc, char **argv)
{
func();
__asm__ ("");
return 0;
}
//////////////// |
| Steps To Reproduce | $ frama-c -machdep gcc_x86_64 asm.c -e-acsl -then-last -print -ocode eacsl_asm.c
[kernel] Parsing FRAMAC_SHARE/e-acsl/e_acsl_gmp_api.h (with preprocessing)
[kernel] Parsing FRAMAC_SHARE/e-acsl/e_acsl.h (with preprocessing)
[kernel] Parsing asm.c (with preprocessing)
[e-acsl] beginning translation.
[e-acsl] asm.c:11: Warning:
E-ACSL construct `asm' is not yet supported. Ignoring annotation.
[e-acsl] translation done in project "e-acsl".
$ gcc -DE_ACSL_SEGMENT_MMODEL -Wno-attributes -I$(frama-c -print-share-path)/e-acsl/ -o asm eacsl_asm.c $(frama-c -print-share-path)/e-acsl/e_acsl_rtl.c $(frama-c -print-share-path)/../../lib/libeacsl-dlmalloc.a $(frama-c -print-share-path)/../../lib/libeacsl-gmp.a -lm
$ ./asm
Assertion failed at line 5 in function func.
The failing predicate is:
\valid(ptr).
Aborted
|
| Additional Information | When one comments the __asm__ line and compare the generated code, it seems that the list of missing functions are :
__e_acsl_memory_clean
__e_acsl_store_block
__e_acsl_delete_block
__e_acsl_initialize
__e_acsl_full_init
The problem is similar on Chlorine and Argon.
i and ptr could also be global static variables, it doesn't change anything
