Untwist param's knickers.

6ce3c5a59a
Get statments being emitted to the code segment.
...
The first function seems to work fine, but there's a problems with the
scope of params causing params to get their knickers in a twist (tangled
linked list).

Give functions their own defspace.
...
The defspace is propogated through the function's sub-scopes.
2011-01-25 12:34:45 +09:00
27c5139612
Give defspaces some backing memory.
...
I'm not sure I want all defspaces to have backing memory, but this will do
for now.

Ensure current_symtab gets set at the start of parsing.
...
current_symtab must be set even if the first thing encountered is a syntax
error.

Might not be the perfect place, but at least they're strongly related.
2011-01-24 21:32:48 +09:00

Fix a few FIXMEs.
2011-01-24 21:13:37 +09:00
afc5b2827d
Simplify def handling, use far data.
...
Since there is now a proper symbol table, defs are now just references to
memory locations and the symbol table takes care of duplicates.
Also, start using far data for ObjQC structures.
The qfo functions have been stubbed out until I figure out what to do with
object files in the new scheme.
2011-01-24 15:41:43 +09:00

4ac80c2932
Get qfcc running again.
...
It segs when it tries to link, but that's because a real object file has
not been created yet. However, I can get my tree and flow diagrams :)
2011-01-22 15:52:57 +09:00
55d3d17807
Add a missing break.

"return" falling through to "goto" was bad news :)

The whole reason for this crazy developement branch :)

Produce flow diagrams of the basic blocks.
2011-01-22 11:40:53 +09:00
246778b5de
Use function pointer tables instead of switch.
...
This seems to be better for complicated code. switch seems to be better
suited for relatively simple code.
2011-01-22 11:40:53 +09:00

Break out print_expr into its own file.

52b561f7cb
Nuke bind expressions.
...
Since I'm planning on implementing CSE and other optimizations, they're
rather redundant (and I'm having trouble getting them to work).
2011-01-21 19:07:58 +09:00
0d01930056
Link a bool to its block rather than the block's head.
...
This makes the flow make a little more sense.

Make operator type overrides clear.

Print expressions as dot files.

While the resulting images can be a little confusing, they're much easier
to read than my cryptic postfix notation.
