483cbeba03 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.

Also get call nodes looking a little better.

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 :)

55d3d17807 Add a missing break.
"return" falling through to "goto" was bad news :)

d5f669af7a Nuke temp reference counting.
The whole reason for this crazy developement branch :)

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.

2f09efe547 Break out print_expr into its own file. 2011-01-21 20:31:40 +09:00

bcb2667b73 Possibly get vector calls working. 2011-01-21 19:40:46 +09:00

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).

0d01930056 Link a bool to its block rather than the block's head.
This makes the flow make a little more sense.

977c48d728 Make operator type overrides clear. 2011-01-21 15:57:53 +09:00

aec9f256a7 Get calls mostly working.
Bind seems to be broken, but parameters seem to be being set correctly.

5c5fa67e43 Minor tweaks of the expression tree output. 2011-01-21 15:34:42 +09:00

4a24393d8d Temp expressions now use operands instead of defs. 2011-01-21 11:26:43 +09:00

2998e578fb Get very basic deref assignments working.
More complicated expressions will not work yet.

e45ea4b2ae Move the statement printing near the top of the file. 2011-01-20 18:07:24 +09:00

35b7278967 Re-disable the next-edge constraints.
This gives a flatter layout.

08e387ebac Slight improvement to branch instruction nodes/labels. 2011-01-20 15:33:13 +09:00

f8cc347dce 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.

ff6e1b4d6c Get functions attempting to generate code.
However, the statements are only printed as expressions.

33db650161 Add QuatInverse to calculate 1/q.
There's still no direct quaternion division because I don't know if the
definition of q1/q2 is (1/q2)*q1 or q1*(1/q2) (it does make a difference).

87ce9f5333 Get basic function creation working.
Even more FIXMEs, but the pascal parser can now create functions. The
function records even get emitted.

21c0c960ae Initialize data before types.
This is needed for string data. It might be better to init saved strings
separately, but this works for now.

Symbols may not have null names.

ea3895805b Rewrite much to use symbols and symtabs. Gut emit.c. Massive breakage.
That which isn't rewritten is horribly broken. However, this does include a
nice mechanism for building QC structs for emitting data.

emit.c has been gutted in the spirit of "throw one away".

There is much work to be done to get even variables emitted, let alone
code. Things should be a little more fun from here on.

85de101aa3 Break out the defspace code.
This also makes some improvements to the free block handling code.

537b930ba6 Add new_symbol_type to ease creation of typed symbols.
This is inteded for code generation functions that need to create
variables and structures.
