Use unique location catalogs to encode Dex register maps.
- For each CodeInfo object (i.e. for each method), compute a
variable index size location catalog of unique Dex
register locations. In Dex register maps, instead of
storing the actual location of a (live) Dex register,
store the index of the location catalog entry containing
that Dex register location.
- Adjust art::StackMapStream,
art::CheckReferenceMapVisitor::CheckOptimizedMethod,
art::StackVisitor::GetVRegFromOptimizedCode, and
art::StackVisitor::SetVRegFromOptimizedCode.
- Add LoadBits and StoreBits methods to art::MemoryRegion
to load and store a block of adjacent bits in a memory
region.
- Update compiler/optimizing/stack_map_test.cc.
- Remove the default value for parameter EmptyFn of
art::HashMap. This default value did not seem to make
sense, as it would create an "empty function" for type Key
by default, whereas art::HashMap expects an "empty
function" for type std::pair<Key, Value>.
