bc1b483525 Nuke the rcsid stuff. 
It's pretty useless in git.

6ead583195 Ruamoko: Implement infinity. 
The special token __INFINITY__, like __FILE__ and friends, will expand to
a floating-point expression containing a value the C compiler considers
infinite. Obviously, this assumes that the system has relatively modern
float hardware -- but if it doesn't, having Ruamoko be able to represent
float infinity is the least of your problems. :)

Bill Currie
55cc0f9206 Bring back the unsigned type (PROGS version bump) 
This is only low-level support (the unsigned keyword still does not work),
but sufficient to make switch statements using jump tables work.

237f11c472 Fix cast expressions. 
Casting between ints and floats needs special treatment to get the
conversion operator, but other casts need to be aliases.

f1d9570dc8 Fix constant value type handling. 
Rename immediate.[ch] to value.[ch] and clean up the mess.

Add convert_value() to convert the type of a value (only scalar types).

f66e20db17 Set the dereferenced type in the field value. 2011-03-08 19:29:36 +09:00
Bill Currie
7198be5726 Treat entities a bit like structures in field_expr (). 
Look in the entity field symbol table for the field before looking in the
normal symbol table. This allows entity fields to be accessed even when
the current scope has symbol of the same name. However, checking the
normal symbol table where there is no such field allows for field
variables when I get around to implementing them.

Bill Currie
993d05b3d3 Support taking the address of alias expressions. 
Taking the address of an alias expression undoes the alias but uses the
aliased type.

45de7327dc Implement alias expressions (finally). 
Alias expressions are like cast expressions, but never do any conversions.

4fd6bdae6f Allow nil to be assigned to field variables. 
Note, this is the field variable itself, not the field in the entity.
eg:
	.integer x = nil;

b2d4aee61e Reimplement selector expressions to work with far data. 
They currently execute a lea instruction every method call, but the
optimizer should take care of that once its written.

976ff8a6bb Allow cast expressions to be lvalues. 
These really need to be alias expressions rather than cast expressions
so the two can be separated as cast expressions should not be lvalues.

0b5565396b Add a class type to symbols and rework the CLASS_NAME handling. 
This fixes the problem with [Array alloc] producing a warning about Class
not repsonding to -alloc.
 2011-02-13 16:05:09 +09:00
Bill Currie
d93d8d7d46 Remove the dirty hack used for accessing params and the return value. 
Instead of using the equivalent of *(float*)&.return, now use the
equivalent of (float).return. No conversion is done in the "cast".

NOTE: this sort of cast should be separated from normal casts.

adeef4a4eb Copy named expressions. 
Since expressions can be modified, making DAGs this early causes
corruption of the expression tree.

3025e04ac5 Partially resurrect field_expr() 
For now, only entity.field and ivar access via a pointer have been
implemented. The rest will come later as needed.

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

Bill Currie
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.

52b561f7cb Nuke bind expressions. 
Since I'm planning on implementing CSE and other optimizations, they're

0d01930056 Link a bool to its block rather than the block's head.

f8cc347dce Print expressions as dot files.

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

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.

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.

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.

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
Bill Currie
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.
