Temporarily disabled (broken) attempt at Regexp parsing	Vidar Hokstad	More...				12 months ago
Fixed selftest output	Vidar Hokstad	More...				over 3 years ago
For statically mentioned symbols we pre-create the symbols at startup, in which case we might as well reference those pre-created symbols from the vtable thunks as well.	Vidar Hokstad	More...				over 3 years ago
Not calling __int for constants shaves ~3k lines of asm off the compiler.	Vidar Hokstad	More...				over 3 years ago
Improve error reporting from shunting yard parser.	Vidar Hokstad	More...				over 3 years ago
Minor cleanup	Vidar Hokstad	More...				over 3 years ago
Make "kleene" method store scanner position and used that to shorted a couple of parser productions	Vidar Hokstad	More...				over 3 years ago
Temporarily disabled attempt at regexp parsing as it broke the selftest	Vidar Hokstad	More...				over 3 years ago
Very minimal and incomplete step towards the parser accepting regexps (but the runtime has no support yet, so even if/when they compile, it won't work yet)	Vidar Hokstad	More...				over 3 years ago
Handle class <<expr; end eigenclass opening.	Vidar Hokstad	More...				over 3 years ago
Holdover from the dark ages (1.8.x compat)	Vidar Hokstad	More...				over 3 years ago
Updated test case	Vidar Hokstad	More...				over 3 years ago
Updated README	Vidar Hokstad	More...				over 3 years ago
Type-tagging for Fixnum/Integer Adds the overhead of checking if bit 0 is set for all attempts to get the class for an object, but as a consequence significantly reduces object creation.	Vidar Hokstad	More...				over 3 years ago
This is a preliminary, experimental, broken first stab at some basic inline support, not currently enabled anywhere (it'd need to be added the transformation stages in transform.rb, but the current form does not work)	Vidar Hokstad	More...				over 3 years ago
Update compilation targets.	Vidar Hokstad	More...				over 3 years ago
Add a very primitive/basic peephole optimizer. This isn't likely to stay in the long run, but it papers over some of the awfulness of the current codegen quality until more serious overhauls are done.	Vidar Hokstad	More...				over 3 years ago
Add '#type' method, as part of slowly migrating towards a more structured AST node	Vidar Hokstad	More...				over 3 years ago
Revert direct references to "cached" integers to calls to (__int ..) in preparation for type tagging.	Vidar Hokstad	More...				over 3 years ago
Improved debugging.	Vidar Hokstad	More...				over 3 years ago
Cleanup	Vidar Hokstad	More...				over 3 years ago
Workaround for compiler bug.	Vidar Hokstad	More...				over 3 years ago
Cleanup	Vidar Hokstad	More...				over 3 years ago
More complete string initialization and avoiding unnecessary object creation.	Vidar Hokstad	More...				over 3 years ago
The Hash class is still absolutely awful and a mess, but committing current state prior to attempt at rewriting it, as this version "works" well enough to self-host the compiler.	Vidar Hokstad	More...				over 3 years ago
Performance fix.	Vidar Hokstad	More...				over 3 years ago
Off by one bug.	Vidar Hokstad	More...				over 3 years ago
Improve handling of global variables.	Vidar Hokstad	More...				over 3 years ago
Flush output	Vidar Hokstad	More...				over 3 years ago
Reduce overhead of method missing vtable thunks.	Vidar Hokstad	More...				over 3 years ago
