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

Fix another double insertion of a symbol.

Fix the creation of enum values.
2011-02-13 15:19:55 +09:00
f24de89a2a
Handle type-modified constants.
...
The fix for pointers broke constants (particularly, enums). Oops.
2011-02-13 14:13:32 +09:00
fa6b8d773c
Correctly emit class and category symtab references.
2011-02-13 13:21:00 +09:00
c4f364fd37
Emit pointers properly.
...
Rename ReuseConstant to emit_value and use emit_value to emit any non-short
constant. This fixes the null pointer in the call to __obj_exec_class.
2011-02-13 10:09:42 +09:00

Move _OBJ_MODULE to the far data space.

Dump the contents of a pointer def.

2011-02-12 22:58:50 +09:00
3505de6868
Point the near and far data spaced into the merged data space.
...
This lets the relocations work on the final data without having to adjust
their locations.
2011-02-12 22:35:44 +09:00
181596f5bf
Make relocation records store the space of the relocation.
...
The space is meaningless for op_* relocations as they are always in the
code space, but def_* relocations need to know which space holds the
location to be adjusted.
2011-02-12 22:34:38 +09:00
cfdc2e5d6b
Complete the documentation for relocations.
...
This covers only in-memory storage of relocation records, not object file
relocations.
2011-02-12 15:55:58 +09:00
8c01497936
Give __obj_exec_class a sterner beating.
...
When linking a def into a defspace, ensure it can be removed. This fixes
the missing __obj_exec_class def in qwaq.
2011-02-11 22:29:57 +09:00

Propogate the specifiers through external_decl_list.

This fixes the undefined defs in qwaq.

Produce cleaner output for a = b op c.
2011-02-11 22:29:57 +09:00
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.
2011-02-11 22:29:38 +09:00

Remove a fixme.

Handle block expressions in is_indirect().
2011-02-11 22:29:30 +09:00
b01f960db9
Disable the subgraphs for now.
...
They tend to make large trees difficult to read. I might re-enable them
when I've gotten a better handle on dot.
2011-02-10 15:11:08 +09:00
2617f9e3ed
Update for the new syntax.
...
With this, qwaq will compile once I sort out the parameters for QC style
functions, and some non-executable warnings. However, as those are
compiler problems, this should be the final qwaq related commit.
2011-02-10 14:58:59 +09:00
c3a991e555
Support nil in initializers.
2011-02-10 14:51:52 +09:00

Yay, I've wanted this feature in qfcc for many years :).
2011-02-10 14:47:24 +09:00
adeef4a4eb
Copy named expressions.
...
Since expressions can be modified, making DAGs this early causes
corruption of the expression tree.
2011-02-10 14:43:49 +09:00

Oops :P
2011-02-09 22:40:16 +09:00
a43946abf3
Give short values special treatment.
...
As a short value fits directly into a statement, it needs a fake def that
holds its value in the def's offset in order for the value to be written to
the statement.
2011-02-09 22:13:43 +09:00

Fix some case&paste errors.
2011-02-09 22:04:54 +09:00
1b8edc07c9
Adjust the offsets of ivars in derived classes.
...
As ivar structs are not independent, their starting offset is not
necessarily zero (almost never will be for derived classes).
2011-02-09 22:02:52 +09:00
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.
2011-02-09 21:45:29 +09:00

Use the correct type object in emit_struct().
2011-02-09 17:15:29 +09:00
59a683d39e
Protect the name passed into emit_struct().
...
The name passed into emit_struct is sometimes created via va(), but the
struct creation code also uses va. This makes a mess of names.
2011-02-09 17:12:47 +09:00

Creation of .ctor now mostly works.

There seems to be problems with the actual code generation using incorrect
addresses, but a very simple test file compiles successfully.

da14c95bb8
Initialize current_symtab in class_init() when necessary.
...
If an objective-qc symbol is the first token to be read, class_init() is
called before the parser gets a chance to perform the initialization
action. However, class_init() setting current_symtab if the first
objective-qc symbol is seen in a function body would be bad.

Most, if not all, of the fixes needed to get qwaq building.

This is pretty much just changing [] to * and moving [N] to the other side
of the variable name.

Set the symbol type for structs etc as soon as the tag is created.

Do not change the type of the return operand.

Doing so made a mess of returning expressions. It was probably a holdover
from before getting instructions with void operand types working.

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

Partially resurrect field_expr()

For now, only entity.field and ivar access via a pointer have been

Make enum values visible.

Put them in the current symbol table as well as the enum symbol table. The
latter is really just for keeping track of what values are in the enum.
