Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
various fixes and enhancements * correct refmap->oopmap conversion (register numbering, stack slot numbering) * fixes for inlining (correct scoping in exception handler lookup, NPE in scope conversion) * support for "jump to runtime stub" (patching code needs to be aware of jmp instruction) * provide more information about methods (to allow inlining: has_balanced_monitors, etc.) * fixes to signature type lookup * isSubTypeOf: correct handling of array classes * RiType: componentType/arrayOf * prologue: inline cache check, icmiss stub * klass state check (resolved but not initialized) in newinstance * card table write barriers * c1x classes are optional (to allow running c1 without them) * correct for stored frame pointer in calling conventions (methods with arguments on stack) * getType(Class<?>) for some basic types, used for optimizations and folding * RiMethod/RiType: throw exception instead of silent failure on unsupported operations * RiType: resolved/unresolved array type support * refactoring: new on-demand template generation mechanism * optimizations: template specialization for no_null_check, given length, etc.
