f2ef24d0cc Make symbols use the new value struct for constants. 2011-01-19 11:09:54 +09:00
Bill Currie
e08efe036b Move the constant expression values into their own struct. 2011-01-19 08:43:24 +09:00
Bill Currie
ff6e1b4d6c Get functions attempting to generate code. 
However, the statements are only printed as expressions.
 2011-01-19 08:38:09 +09:00
Bill Currie
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
Bill Currie
8fb1b49a9d Add support for function symbols. 2011-01-18 10:46:42 +09:00
Bill Currie
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.
 2011-01-17 12:04:41 +09:00
Bill Currie
fb8b3d1211 Rework the lexer and parser to use symbols instead of defs. 
Currently parses the test program just fine, but code generation is very
very broken.
 2011-01-13 14:58:16 +09:00
Bill Currie
8f71986306 Add symbol expressions (like def expressions). 
They will eventually replace def expressions. Currently quite broken.

5b8725ca66 Rewrite the symbol (table) management in light of actual usage. 2011-01-13 14:48:38 +09:00
Bill Currie
ac14db7b1b Create a function to ease param list building. 
This is especially useful for QuakePascal, but it will mean I'll be able to
get rid of the parameter reversals in Ruamoko later on.
 2011-01-13 14:45:53 +09:00

abe471110c Make inc/dec_users return the the expression.

a1f36a9944 Make new_function take a def rather than a name. 
Moves into new_function some code that should have been there in the first
place.
 2011-01-03 16:25:29 +09:00

530e8fae34 Rework class_type_t to be more useful.

reporting).

4481ba9b0d Allow explicit references to classes and categories. 
Use "@reference ClassName;" or "@reference ClassName(CategoryName);" to
create a refence to the class or category, forcing the defining object file
to be linked into the program when the object file is part of a library.

64cc8c60d2 compile time protocol support seems to be complete now. fortunatly, protocols had never been written out so the corrections to the protocol related stuctures do not need a progs version bump. runtime protocol support hasn't been fully tested yet. 
+load runtime support seems to be working.

This is an imperfect revision of history.

385a90e8fb correct pr_symtab_t to include the pointer to the array of selectors used
