| | | | | | | | | | | | | | As detected by the new warning in Coq 8.12. The use of Fixpoint here is not warranted and either an oversight or a leftover from an earlier version.

| | * Explicit error messages for ill-formed section attributes (#232)Bernhard Schommer2020-03-292-10/+23
| | | | | | | | | | | | | | | | | | | | | | | | Introduce an error message for section attributes with non string arguments,and another for multiple, ambiguous section attributes. This is more consistent with the handling of other attributes, like packed, than the old behavior of silently ignoring them.

| | | | | | | | | | | | | | | | | | | | The proof script for Events.excall_free_ok was incomplete if Archi.ptr64 is unknown (as in the RISC-V case).
| | | * Define the semantics of `free(NULL)` (#226)Xavier Leroy2020-03-021-14/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to ISO C, `free(NULL)` is correct and does nothing. This commit updates accordingly the formal semantics of the `free` external function and the reference interpreter. Closes: #334
| | | * Weaker ec_readonly condition over external calls (#225)Xavier Leroy2020-03-021-15/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently we require the memory to be unchanged on readonly locations. This is too strong. For example, current permissions could decrease from readonly to none. This commit weakens the ec_readonly condition to the strict minimum needed to show the correctness of value analysis for const globals.

| | * | Refine the type of function results in AST.signatureXavier Leroy2020-02-219-80/+189
| | |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | Before it was "option typ". Now it is a proper inductive type that can also express small integer types (8/16-bit unsigned/signed integers). One benefit is that external functions get more precise types that control better their return values. As a consequence, the CompCert C type preservation property now holds unconditionally, without extra typing hypotheses on external functions.
