Fix a few FIXMEs.

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
ce02fe8660
Fix the order of paramenters in the tree output.
...
Also get call nodes looking a little better.
2011-01-23 12:59:30 +09:00
a79b6f0a6c
Partially implement casts.
2011-01-23 11:53:08 +09:00
bf626c9e00
Fix some simple fixmes
2011-01-23 11:13:56 +09:00
20b14af024
Add "is_math" type check and use for unary +/-.
2011-01-23 11:12:58 +09:00
341f370662
Rename is_math() to is_math_op().
2011-01-23 11:12:05 +09:00
dea6771d92
Create type_nil for passing nil into ...
2011-01-22 16:41:31 +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 :)
2011-01-22 15:52:01 +09:00
d5f669af7a
Nuke temp reference counting.
...
The whole reason for this crazy developement branch :)
2011-01-22 11:40:53 +09:00
3b462e16cf
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
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).
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.
2011-01-21 18:50:17 +09:00
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.
2011-01-21 15:54:53 +09:00
5c5fa67e43
Minor tweaks of the expression tree output.
2011-01-21 15:34:42 +09:00
96fae582e3
Implement bind expressions.
2011-01-21 11:27:40 +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.
2011-01-21 10:59:16 +09:00
ff6e2584da
Handle block sub-expressions that produce results.
2011-01-21 10:57:47 +09:00
16e013ff5d
Allow the operand to override the symbol's type.
2011-01-21 10:56:32 +09:00
3f2793ef72
Get a lot of statements being generated.
2011-01-20 23:26:13 +09:00
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.
2011-01-20 15:36:10 +09:00
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.
2011-01-20 15:23:19 +09:00
0594609b3a
Get the label from the right expression.
2011-01-19 22:25:43 +09:00
5deda9c9b9
Clean out ex_def as ex_symbol replaces it.
2011-01-19 22:25:04 +09:00
b5424bca7d
Start work on getting expressions converted to internal statements.
2011-01-19 15:47:45 +09:00
cac2e04b18
Avoid namespace issues with dstatements.
2011-01-19 11:35:34 +09:00
f2ef24d0cc
Make symbols use the new value struct for constants.
2011-01-19 11:09:54 +09:00
e08efe036b
Move the constant expression values into their own struct.
2011-01-19 08:43:24 +09:00
ff6e1b4d6c
Get functions attempting to generate code.
...
However, the statements are only printed as expressions.
2011-01-19 08:38:09 +09:00
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).
2011-01-18 22:22:18 +09:00
87ce9f5333
Get basic function creation working.
...
Even more FIXMEs, but the pascal parser can now create functions. The
function records even get emitted.
2011-01-18 12:47:13 +09:00
8fb1b49a9d
Add support for function symbols.
2011-01-18 10:46:42 +09:00
b186173d18
Fix a segfault in structure finalization.
2011-01-18 08:59:44 +09:00
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.
2011-01-18 08:58:43 +09:00
3fe7a7250a
Handle unnamed structures in make_structure.
...
Symbols may not have null names.
2011-01-18 08:56:47 +09:00
b76a5c5284
Add my QuakePascal test program.
...
Trivial as it is...
2011-01-17 22:44:58 +09:00
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.
2011-01-17 22:34:41 +09:00
85de101aa3
Break out the defspace code.
...
This also makes some improvements to the free block handling code.
2011-01-17 22:34:41 +09:00
d3a98af783
Make internal_error globally available.
2011-01-17 22:34:41 +09:00
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.
2011-01-17 12:04:41 +09:00
ffea505678
Cleanup QC's constant handling based on QP.
2011-01-14 12:10:28 +09:00
c38ea0b1bc
Correct the spelling of "nil".
