The target in this case is 8-bit, accumulator based, however it is Von Neumann; so - good to know it's not *quite* the "Trifecta of Doom". LLVM offers some very attractive features for our usage, and it would be disappointing to abandon it as an option all together. Faced with the alternative being to write the compiler from scratch, is the consensus that doing so will be a better path forward for us than a new LLVM b...

I''ve got a test suite trifecta going here; all three need review, comments and (hopefully) approval: http://dev.rubyonrails.org/ticket/9019 "Fix time_with_datetime_fallback on really old dates" This is a bug in time_with_datetime_fallback. The test suite currently fails for me without this patch. http://dev.rubyonra...

I've been looking closely at LLVM as a means to developing a new toolchain for an MCU core of very similar architecture. To that end, the once included PIC16 backend might be a valuable reference. I found a message in April of this year that indicated it had been dropped from new releases however, and that were it to be resumed "it will be largely a rewrite". I'm wondering if
