* Removed code related to "divided" option.Gravatar Unknown2012-08-13

* Barrier divergence checking now achieved via precondition.Gravatar Unknown2012-08-13
| | | | | | Race checking assertions contain tags to identify them. Attributes are passed correctly through the dualisation process.
* Unstructured and smart predication are now default options for GPUVerify.Gravatar Unknown2012-08-09
| | | | | | The executable produced by building the project is now GPUVerifyVCGen. Refactored the way "other" functions are handled to make this more easily extensible.

| * GPUVerify: merge blocks into predecessors before and after predicationGravatar Peter Collingbourne2012-07-09
|/ | | | | | | Because predication produces straight line control flow, merging after predication can dramatically reduce the number of blocks to 1 plus 2-3 per loop. We also merge before predication, which reduces VC complexity by reducing the number of possible values for cur.

* | GPUVerify: implement generic reduced strength analysis for loop countersGravatar Peter Collingbourne2012-06-26
| | | | | | | | | | | | | | | | | | | | All counters which we are able to infer facts about now receive a candidate invariant _before_ predication, dualisation etc. This is probably a more natural place to insert such invariants, and means that they are also subject to predication etc. without us having to do anything. Also, kill the id plus constant analyses, which are no longer used.

| * GPUVerify: implement is-a-constant analysisGravatar Peter Collingbourne2012-06-15
| | | | | | | | | | | | | | | | | | | | | | | | | | This analysis is used to generate race checking invariants for arbitrary (thread-level) constant offsets, in place of invariant generators for four specific constants (thread-id, global-id, 2D thread-id and 2D global-id) which are subsumed by the new analysis. The main motivation is to be able to recognise offsets used by word level accesses into byte arrays, which are formed from linear combinations of thread IDs and constants. This change allows us to remove the 2D and global size analyses, resulting in a 536-line net reduction in total code size.
