* | | Value analysis: keep track of pointer values that leak through small ↵Xavier Leroy2015-07-192-21/+21
| | | | | | | | | | | | | | | | | | integers with Uns or Sgn abstract values. This is a follow-up to commit 2932b53. It adds provenance tracking to the Uns and Sgn abstract values.
* | | Value analysis: keep track of pointer values that leak through arithmetic ↵Xavier Leroy2015-07-191-2/+2
| |/ |/| | | | | | | | | 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.

| * Extended inline asm: revised treatment of clobbered registers.Xavier Leroy2015-05-093-27/+43
| | | | | | | | | | | | | | | | | | | | - Treat clobbered registers as being destroyed by EF_inline_asm builtins (which is the truth, semantically). - To enable the above, represent clobbers as Coq strings rather than idents and move register_by_name from Machregsaux.ml to Machregs.v. - Side benefit: more efficient implementation of Machregsaux.name_of_register. -# Please enter the commit message for your changes.
