| | | * Chalice: Update reference file for a test (a recent improvement makes the ↵Gravatar stefanheule2012-09-13

| * Chalice: Switch to latest Scala release (there seems to be a compiler bug ↵Gravatar stefanheule2012-09-12
| | | | | | | | with 2.8.1 that prevents the current code from compiling).
| * Chalice: Also add time information for reg_test, reg_test_all and runalltests.Gravatar stefanheule2012-09-11

| | | | | | | | | | | | | | | | | | | | up creating code that the Boogie parser gets a stack overflow while trying to parse!

|/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | in the code model) into the sink so that the different statement traversers used for things like if-then-else statements share the same stack. Fixed a problem in the dispatch table for whole program virtual dispatch so it works for generic methods. Found input that either crashed the translator or caused it to produce bad Boogie: "fixed" it by having the translator thrown an exception so the method containing the bad code is skipped.
| | * Chalice: added findFunctionAppsContaining(..) to Expression, which finds all ↵Gravatar Unknown2012-09-08
| | | | | | | | | | | | | | | | | | the function applications with at least one variable in common with a given list. This is a pre-cursor to writing a trigger-generating routine for quantifiers. Also corrected some copy-paste comments in Translator.scala
| | * Chalice: implemented the final cases of the "inside" feature for predicates. ↵Gravatar Unknown2012-09-08
| | | | | | | | | | | | | | | | | | At the same time, exhaling an unfolding expression now generates corresponding secondary permission information (this can in principle be useful; with fractional permissions it need not be the case that just because we exhale (part of) a predicate, we don't have any left. Also added a test case to test the new non-aliasing knowledge the "inside" encoding provides in various situations.
