Auto-cast between enums and the default type.

Make adding a symbol to multiple tables an internal error.
2011-02-06 20:00:14 +09:00
67957a14df
Bring back convert_name(), but siimplified.
...
It is now mainly for converting __FILE__ etc, handling expression symbols,
and checking for undefined identifiers.
2011-02-06 14:29:14 +09:00
1f6abb2cce
Minor cleanups to message_expr().
...
Fix for class names no longer being pointers to the class.
2011-02-04 23:22:51 +09:00
eff3957487
Resurrect the address expression code for arrays etc.
...
This fixes selector finding.
2011-02-04 23:20:37 +09:00

Fix conversion of nil to a real type.
2011-02-03 21:37:15 +09:00
c158b14286
Remove the labels list from the pr struct.
...
I'm not sure they were ever needed.
2011-01-28 11:40:25 +09:00
a6e65488ec
Remove the "test" parameter from test_expr.
...
The parameter became redundant at some stage.
2011-01-27 08:31:51 +09:00
5231e8e9f8
Handle .zero, .return and .param* properly.
2011-01-26 08:01:24 +09:00

Move the diagnostic functions into their own file.
2011-01-24 21:54:57 +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

Fix some simple fixmes
2011-01-23 11:13:56 +09:00

Add "is_math" type check and use for unary +/-.
2011-01-23 11:12:58 +09:00

Rename is_math() to is_math_op().

Create type_nil for passing nil into ...

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

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

Re-disable the next-edge constraints.
...
This gives a flatter layout.
2011-01-20 15:36:10 +09:00

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
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
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
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
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
d3a98af783
Make internal_error globally available.
2011-01-17 22:34:41 +09:00
8f71986306
Add symbol expressions (like def expressions).
...
They will eventually replace def expressions. Currently quite broken.
2011-01-13 14:54:24 +09:00
258c896e4d
Create a function to build if/else blocks.
2011-01-13 14:33:16 +09:00
c787923c99
Forgot to remove that print_expr.
2011-01-11 12:11:54 +09:00
08bf7e24de
Produce nicer code for post-op.
...
The temp notice is still there for arrays (that's caused by issues in
constfold.c, not easily fixilbe), but it's harmless and correct (and nice)
code is much more important.
2011-01-11 12:07:48 +09:00
ad787ae98a
Set the expression type to the correct value for addresses.
2011-01-11 12:06:40 +09:00
21d7c78eb7
Allow deep copying of expression trees.
...
Certain expression types (eg labels) are created fresh.

abe471110c
Make inc/dec_users return the the expression.
...
Just for convenience.
2011-01-11 08:44:43 +09:00
18ae178eaf
Make new_vector_expr and new_quaternion_expr const-correct.
2011-01-11 08:43:34 +09:00
cd38bd71fa
Swap the order of scale and base for calculating the array index.
...
fold_constants doesn't like dags very much, but it can do the right thing
if the expressions are in the right order. This is merely a workaround
until I get to work on the code generator itself.
2011-01-10 12:26:11 +09:00

Clean out some unnecessary types from the progs engine and clean up the mess.

This is a nasty commit, sorry, but 99% of the commit is interdependent.

More expression docs.
2011-01-03 16:25:59 +09:00

Use the method's selector rather than its def name in error messages.
2011-01-03 16:25:29 +09:00
a4635d79e8
Slightly more informative error locations.
...
Inside a class or protocol definition is not "at top level" ;)
2011-01-03 16:25:29 +09:00
530e8fae34
Rework class_type_t to be more useful.
...
This allows current_class to refer to procols as well (for error
reporting).
2011-01-03 16:25:29 +09:00
52e844ee48
Produce slightly better v6 modulo code for complex inputs.
...
I'm having problems with temp defs, but I imagine this code is rarely used
so I won't worry about it for now. It will, however, make a good test case
for when I rework emit.c after I do some reading.
2010-12-19 11:23:33 +09:00
d981968208
v6 modulo implementation now produces good code.
...
At least for simple inputs, anyway. That needs to be tested next.
2010-12-18 22:21:55 +09:00
00e50c0ad3
Rewrite the v6 modulo implementation.
...
While trying to understand bind expressions, I discovered that the v6
modulo code was incorrect. This version is correct but uses one too many
temps. That's next.
2010-12-18 22:21:55 +09:00
