Sweet! Can you send me the latest template? ... I haven't implemented the opcodes for anything more than a disassembly, so if you try to emit C code, Sun, 05 Jul 2009 00:44:54 GMT Neil Bradley http://tech.groups.yahoo.com/group/staticrecompilers/message/323 http://tech.groups.yahoo.com/group/staticrecompilers/message/323 ... Well, that's lucky! Usually it completely goes off into the weeds when it attempts to disassemble data. ... The 6502 module wasn't complete and probably Sun, 05 Jul 2009 00:41:30 GMT Graham Toal http://tech.groups.yahoo.com/group/staticrecompilers/message/322 http://tech.groups.yahoo.com/group/staticrecompilers/message/322 ... and when I made the $FF opcode into data, it generated an output file just fine, and the few missing code sections all look to be there now...

That's pretty good! Comparing it manually to http://www.brouhaha.com/~eric/retrocomputing/apple/apple1/basic/a1basic.dis all I've seen so far is a missing Sat, 04 Jul 2009 22:10:27 GMT Neil Bradley http://tech.groups.yahoo.com/group/staticrecompilers/message/320 http://tech.groups.yahoo.com/group/staticrecompilers/message/320 ... Well, that wouldn't have worked as it hit several opcodes that weren't implemented. Here is a new recomp.exe, template, and ROM image for the Apple1: Sat, 04 Jul 2009 21:04:19 GMT Neil Bradley http://tech.groups.yahoo.com/group/staticrecompilers/message/319 http://tech.groups.yahoo.com/group/staticrecompilers/message/319 ... It's looking for the vectors at 0xfff8-0xffff, which is probably all 0s unless you load something there.

Of course! LLVM is a compiler back-end - you feed it your AST and it does all the optimisations on the AST for you, and has a choice of target code Sat, 04 Jul 2009 18:59:37 GMT Neil Bradley http://tech.groups.yahoo.com/group/staticrecompilers/message/317 http://tech.groups.yahoo.com/group/staticrecompilers/message/317 ... Are you referring to AST + target or just target? I would think the AST route is the way to go. ... Does someone have a copy of the Apple 1 EPROM?

As far as I understand it, SSA is part of LLVM so using LLVM provides you with SSA optimised code for free, which is good.

Hi Neil - Cris Cranford over in "compilers101" is in the early stages of writing a BASIC as well - I can't remember if I ever dragged you into that group Sun, 31 Aug 2008 07:28:43 GMT Neil Bradley http://tech.groups.yahoo.com/group/staticrecompilers/message/312 http://tech.groups.yahoo.com/group/staticrecompilers/message/312 Yeah, I know, not strictly on topic, but I just got my expression evaluator emitting correct uOps for a BASIC interpreter. Anyway, a sequence like this: Dim
