Luna 61c8493484 add basics of stack-stored arguments 
this requires some changes regarding the const-ability of the passed
nodes into codegen.
 2019-09-28 11:40:56 -03:00
Luna 178acc656f codegen: allow for mutable statements 
- ast: add llvm_alloca llvmvalueref pointer in VarDeclStmt
 2019-09-28 11:30:21 -03:00
Luna d235ce0d13 add codegen for allocating vardecls onto stack (not init yet) 
codegen pass needs type information about the variable. thankfully,
analyze pass already did the hard work for it, and scope info has types
of all its declared names. we use that info to generate the alloca

to have information about which current scope we are, we add a "child
index" to scopes so we can repoint current context at them instead of
bumpScope(), which always creates new, empty ones.

initializer exprs are next
 2019-09-27 22:36:35 -03:00

- comp_ctx: replace Function.symbols to Function.env
 2019-09-26 00:11:48 -03:00
Luna 45275d73db change variable declarations to statements 
doing them as expressions was a hack since no 'var' keyword,
also, yeet the := operator from the parser.
