annotate src/share/vm/shark/sharkContext.hpp @ 5763:a3d71693e0ce
removed bytecode disassembly from CodeCacheRuntime into separate BytecodeDisassembler class
removed VM call for doing bytecode disassembly
added support for explicitly excluding classes from JaCoCo (put '// JaCoCo Exclude' somewhere in the source file)
added node intrinsics to MaterializeNode
added snippets for the UnsignedMath classes
each file opened by CFGPrinter now includes a unique id in its name to avoid a race of multiple threads writing to the same file
the IdealGraphPrinter uses the new BytecodeDisassembler mechanism
teh UnsignedMath class is exclude from JaCoCo processing as it is used in snippets
