    • [Ada] Don't split AND THEN expressions in GNATprove_Mode · 270c6b4d 
      Splitting AND THEN expressions in contracts into separate pragma Check
is only useful for compilation when the error message points to a failed
conjunct. For proof it is of no use; for flow analysis it is annoying.
Also, it makes debugging harder. Now it is disabled in GNATprove_Mode.

Compilation is not affected, so no test provided.

    • [Ada] Fix handling of Pre/Post contracts with AND THEN expressions · f062a975 
      Pre- and postconditions with top-level AND THEN expressions are broken down
into checks of indivudial conjuncts for more precise error reporting. This
rewrite interfers with detection of potentially unevaluadted use of 'Old,
e.g. a contract like "Pre => Foo and then Bar" is rewritten into a two
pragmas Check, for expressions "Foo" and "Bar", but the latter remains
potentially unevaluted. This patch fixes detection of the AND THEN rewrite.

This fixes inlining in the GNATprove mode, i.e. the following testc case must
not emit a warning like:

contract1.adb:14:07: info:
  no contextual analysis of "Foo" (in potentially unevaluated context)

    • [Ada] Performance degradation with references · 692918a9 
      This patch modifies the creation of markers for variable references in the
context of SPARK elaboration checks. Previously, prior to checking whether a
reference requires such a marker, the compiler performed a logarithmic look up
to determine whether the reference appears within a call. This action caused
the compiler to degrade when a source program contains multiple (100,000s)
references. Now, the compiler no longer performs the look up immediately.
