2009-07-04adapt emulator for generator changes:Benedikt Böhm14-219/+450
- new instructions (push, pop, call, ret) - new pseudo-registers (bp, sp, rv) - new binary format - dynamic register file size - removed obsolete instructions
2009-07-04implement the code generatorJana Rekittke2-3/+182
2009-07-04adapt parser for backend changesBenedikt Böhm3-34/+69
- emit a prologue/epilogue for functions - emit a "JMP main" instruction in the beginning - track the last function label across genrate calls - split scope in params and local variables (they have a different layout on the stack)

2009-06-30implemented scope and most of astAndreas Nüßlein5-172/+238
2009-06-29fix function_callBenedikt Böhm5-84/+41
- function_call is now an expression and a statement - call keyword is required to make lookahead = 1 work
2009-06-28fixed error with not newline at file endAlexander Sulfrian4-40/+43
moved __init__.py with testcode from src/front to src/ added in lexer "\n\n" at source end to have a newline at file end added unexpected end of file message, if matched token is None
2009-06-23added parserAlexander Sulfrian4-69/+232
- commited parser (Michael Popov) - changed encoding of parser.py to utf8

2009-05-26tac and ast updates - added eval to ast-elemsAndreas Nüßlein2-44/+162
every ast-element now has a .eval-method that creates the ThreeAddressCode for said element. Also: tac-elements are stored linear in a list (, duh)
2009-05-25add scope, and symbol class, obsoletes SymbolTableBenedikt Böhm3-30/+54
2009-05-22added ThreeAddressCode classAndreas Nüßlein1-0/+50

2009-05-20implemented lexer (with tokens and symbolTable)Alexander Sulfrian4-61/+215
todo: beautify code, implement token classes for parser implemented test function with testcode moved token class to single file (token.py)
