* | | | | Value analysis: keep track of pointer values that leak through arithmetic ↵ | Xavier Leroy | 2015-07-19 | 5 | -163/+171 | |
| | | | | | | | | | | | | | | | | | | | | | | | | operations with undefined behaviors. Consider (x ^ 1) ^ 1 where x is a intptr_t containing a pointer value. "x ^ 1" evaluates to Vundef in the CompCert semantics, hence the value analysis, in strict mode, gives abstract result Ifptr Pbot (= any number but not a pointer). In relaxed mode, we now give abstract result Ifptr (poffset p) where p is the abstraction of the pointer, thus keeping track of the actual leak of the pointer value. | |||||
* | | | | ValueDomain.aptr_of_aval: be more conservative with pointers synthesized ↵ | Xavier Leroy | 2015-07-18 | 2 | -6/+14 | |

With this change, in relaxed value analysis mode, it is treated as interfering with any load except those from the current stack frame. | |||||

| * | | Turn off copy optimization when returning a composite by reference. | Xavier Leroy | 2015-07-08 | 4 | -5/+50 | |
| | | | | | | | | | | | | | | | | | | The copy optimization is not correct in case of overlap between destination and source. We would need to use an hypothetical __builtin_memmove_aligned that can cope with overlap to implement the copy at return of callee. | |||||

| | | | | | | | | | | | | | | | | | | | | | | | | As per ISO C99, "hosted environment". "return 0" is added at the end of any function named "main" that has "int" as return type. If the name is "main" but the return type is not "int", emit a warning and do not add anything. | |||||
