view src/share/vm/graal/graalJavaAccess.hpp @ 5760:87e8baf5447c
added snippets for lowering array creation and initialization (in NewObjectSnippets)
made it possible to use node intrinsics with arguments that may only be constant when a snippet template is created
rename: NewTypeArrayNode -> NewPrimitiveArrayNode
removed HotSpotVMConfig.getArrayOffset() - Kind.arrayBaseOffset() is used instead
renamed field prototypeHeader to initialMarkWord in HotSpotResolvedJavaType
rename: NewInstanceSnippets -> NewObjectSnippets
renamed node intrinsics in DirectObjectStoreNode to include the type of the value being stored (to avoid accidental misuse)
extended WordTypeRewriterPhase such that ObjectEqualsNodes are replaced with IntegerEqualsNodes when the values being compared are words (which allows '==' and '!=' to be used between Word values in Java source code)
