Description: Issues related in creating a compiler

Open Issues

JRUBY-1268	UNRESOLVED	Disabling JIT is not sufficient for tracing, since tracing may be enabled during execution of a JITed method
JRUBY-2853	UNRESOLVED	Examine each deoptimization case in ASTInspector to see if it's still valid or could be eliminated
JRUBY-2112	UNRESOLVED	Incorrect lines in exception backtraces
JRUBY-2680	UNRESOLVED	When JIT Compiler compiles the append_features in the ruby\site_ruby\1.8\builtin\javasupport\proxy\interface.rb the compiled code slows down by a factor of 10
JRUBY-2765	UNRESOLVED	Attr assign for block arguments is still slow, both in bytecode and in not call-site caching
JRUBY-2349	UNRESOLVED	Bug in constant lookup on non Module or Class
JRUBY-2555	UNRESOLVED	CLONE -JIT max and JIT threshold should be adjusted for improvements in JRuby over the past months
JRUBY-2048	UNRESOLVED	Call site caches may not be thread safe

JRUBY-2621	UNRESOLVED	Something in ruby_parser is too long to compile, but doesn't get broken apart correctly
JRUBY-2600	UNRESOLVED	Specific-arity call paths through compiled code have extraneous stack frames
JRUBY-2180	UNRESOLVED	break performance is slower than MRI, sometimes slower than interpreted
JRUBY-1852	UNRESOLVED	define_method methods do not JIT and are generally slower unless the code that contains them is compiled before they are defined
JRUBY-48	UNRESOLVED	Ability to write JUnit4+ tests in JRuby
JRUBY-1603	UNRESOLVED	Boxed variable compilation could use lighter-weight scopes
JRUBY-1602	UNRESOLVED	Boxed variable compilation doesn't detect eval within closures

JRUBY-2755	UNRESOLVED	Precompiled scripts do not set initial position information correctly
