Bill Currie 01a7af17e5 Beat __obj_exec_class into submission. 2011-02-10 00:15:19 +09:00
Bill Currie d66a441867 Write out the far data space as well as the near.
This causes the Objective-QC structs to be emitted now that they havve been
moved to the far data space. Relocs are broken, though.

Bill Currie 0d5ab6600d Store the source expression in a statement.
This makes problem reporting more informative.

Bill Currie 3c849b970b Handle union access now that they're detected properly. 2011-02-08 14:45:48 +09:00
Bill Currie ef2ad46f7a Convert complex types to a suitable low-level type.
This takes care of moving structures etc around.

Bill Currie 28ba4b5712 Correct a comment. 2011-02-07 09:56:33 +09:00
Bill Currie 76034861c9 Implement direct ivar access in methods.
A warning needs to be generated for access to ivars in a class method, but
it seems to work (unable to check due to other errors).
2011-02-07 08:32:52 +09:00
Bill Currie 2860a8b28b enum too is a scalar. 2011-02-06 20:01:55 +09:00
Bill Currie 2f7b892452 Fix passing messages to classes.
Rename class_pointer_def() to class_pointer_symbol() and use it when a
class name is used as the receiver of a message.
2011-02-06 14:34:40 +09:00
Bill Currie 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 d9446c5eb0 Fix builtin methods. 2011-02-04 22:31:22 +09:00

Bill Currie 04b86fcdb7 Move the Objective-QC structs from type.c to class.c 2011-02-04 12:07:32 +09:00
Bill Currie d12cdca758 Functions and enums now seem to be working properly.
find_type now operates recursively (depth-first) so built up typechains
work as expected.

@overload is treated as a specifier (directly as a storage class, similaar
to typedef).
2011-02-03 10:48:12 +09:00
Bill Currie 400abe7fce Allow freeing of typechains. 2011-02-02 15:15:24 +09:00
Bill Currie 1452da676d Allow types to be built from the outside in.
This is required for C style decl processing.
2011-02-02 15:07:44 +09:00
Bill Currie 80ce179bc2 Scan the param list for problems with void. 2011-02-01 21:18:08 +09:00
Bill Currie c53001800a Create a struct for representing specifiers.
The specifiers are yet to come (next few commits), but this will be
necessary when they do.
2011-02-01 21:15:51 +09:00
Bill Currie 917c5f08b0 Make a var representing the default type.
The default type for vars is integer for ruamoko and float for v6 qc.
2011-02-01 21:12:02 +09:00
Bill Currie 834417b8c8 Add "debug" diagnotic printing, and use it.
Debug diagnostics are silent for verbosity levels less than 1.
2011-01-28 13:28:45 +09:00
Bill Currie 90a2738459 Add the label to the block to which it refers. 2011-01-28 11:41:53 +09:00
Bill Currie 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
Bill Currie cdea1d07aa Produce code for progs.src mode.
Separate compilation will take fixing object files.

The generated code is broken due to various relocation fixups being
broken, and float immediates seem to be badly broken.

Debug information is broken too.
2011-01-27 15:44:11 +09:00
Bill Currie a6e65488ec Remove the "test" parameter from test_expr.
The parameter became redundant at some stage.
2011-01-27 08:31:51 +09:00
Bill Currie 36c99a8da1 Get function def creation working again. 2011-01-26 14:48:22 +09:00
Bill Currie 6ce3c5a59a Get statments being emitted to the code segment.
The first function seems to work fine, but there's a problems with the
scope of params causing params to get their knickers in a twist (tangled
linked list).
2011-01-25 15:46:48 +09:00
Bill Currie fd3b594ca5 Move label relocs to the relevant statement block. 2011-01-25 15:45:31 +09:00
Bill Currie f45919df09 Need alias defs after all. 2011-01-25 15:42:26 +09:00
Bill Currie a648f043de Give functions their own defspace.
The defspace is propogated through the function's sub-scopes.
2011-01-25 12:34:45 +09:00
Bill Currie 726f293d0d Allocate space for defs and handle basic initializations.
Block initializers (arrays and structs) are still broken.
2011-01-25 12:16:13 +09:00
Bill Currie 7e914b8c53 Fix copyright headers.
Add forgotten templates and fill in the information in places I had
forgotten. I hope I got the dates right (timezone issues).

Bill Currie d618e51dc8 Move save_string and make_string into strpool
Might not be the perfect place, but at least they're strongly related.
2011-01-24 21:32:48 +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.
2011-01-24 15:41:43 +09:00
Bill Currie 20b14af024 Add "is_math" type check and use for unary +/-. 2011-01-23 11:12:58 +09:00
Bill Currie 341f370662 Rename is_math() to is_math_op(). 2011-01-23 11:12:05 +09:00

Bill Currie d5f669af7a Nuke temp reference counting.
The whole reason for this crazy developement branch :)
2011-01-22 11:40:53 +09:00
Bill Currie 3b462e16cf Produce flow diagrams of the basic blocks. 2011-01-22 11:40:53 +09:00
Bill Currie 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
Bill Currie 4a24393d8d Temp expressions now use operands instead of defs. 2011-01-21 11:26:43 +09:00
Bill Currie 16e013ff5d Allow the operand to override the symbol's type. 2011-01-21 10:56:32 +09:00
Bill Currie 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
Bill Currie 5deda9c9b9 Clean out ex_def as ex_symbol replaces it. 2011-01-19 22:25:04 +09:00

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.
2011-01-17 22:34:41 +09:00
Bill Currie 85de101aa3 Break out the defspace code.

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.
2011-01-13 14:54:24 +09:00
Bill Currie 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

Bill Currie 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
Bill Currie 530e8fae34 Rework class_type_t to be more useful.
