Summary

0000728: Arguments are not checked when function call precedes function declaration

Description

Cil allows a function to be called before being defined but does not check that the number/types of argument correspond. See for instance tests/misc/call_variadic.i, which fails with frama-c -check, while the error should be reported directly when type-checking.

Tags

No tags attached.

has duplicate

Several types for the same function

Notes
(0001597) yakobowski (manager) 2011-03-11 13:29	Here is also an example that confuses deeply the value analysis, because of the absence of cast: int f(); void main () { char c = 1; f(c); } int f(int i) { return 2*i; }

(0002402) virgile (developer) 2011-10-20 15:19	tests/misc/call_variadic.i was removed from svn. Here it is: int G; int H; int main () { int T=99; H= f(2); return T; /* gcc -O0 -> 26; gcc -O3 -> 99 */ } int f(int x,int y, int z, int t,int t1,int t2,int t3,int t4,int t5,int t6) { x = 17; y=18; z=19; t=20; t1= 21; t2 = 22; t3 = 23; t4= 24; t5 = 25; t6 = 26; return x; }
