81fd718403 codegen: emit vardecl initializer 2019-09-27 22:49:33 -03:00
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

3f48be3420 codegen: prepare for variable emitting 2019-09-27 17:18:38 -03:00
7def9abc5a add "variable metadata"
this is inserted in the analysis pass into a map from expr ptrs to
metadata in the compilation context itself, this enables codegen to
fetch that metadata with the expr pointer

the other approach was embedding it into the variable expr itself (as
seen by VariableExpr), but that causes a compiler crash

362fc7e3ef analysis: add name type resolution
this only adds resolution for the types. for the actual metadata, such
as e.g parameters, that isn't available, so codegen isn't helped by
this.

2019-09-26 22:22:11 -03:00
dfb954c39c analysis: insert "incomplete" function as soon as possible
by inserting it before we analyze statements, we allow ourselves to
analyze statements *with the data we already have*, for example, we can
now check the return statements' type, and see if it matches with the
functions' declared return type.

this is done via setting CompilationContext.cur_function on insertFn()

 - don't just ignore function analysis if its incomplete, do an error

also, yeet the := operator from the parser.
