annotate src/os_cpu/solaris_x86/vm/orderAccess_solaris_x86.inline.hpp @ 4558:3706975946e4
Make graph dumping a bit more robust when there is no method, enable debug in the startCompiler method, add context and scope for snippets installation
Made IGV display graphs even if some edges are problematic
When schedule failed don't use it
