Syntax fixes for ruamoko/gui.
...
Once aggregate initializers are working, ruamoko/gui will "compile"
(no object files, and still the bogus integer constant into ... warning).

Preserve the ivars inheritance chain across build_struct().
...
build_struct() unlinks the structure symbol table from its parent, but
that breaks the ivar inheritance chain.

Allow same-type re-declarations of uninitialized variables.

This is especially important for declaring variables that were previously
declared external.

Generate a warning when creating a var with no type.
...
This makes the internal error in new_def() non-functional, but the warning
will catch the bug and there's no harm in leaving the test in new_def().

Enable the small struct optimization.
...
For now, anyway. It would probably be much better to handle this sort of
thing in the optimizer stage.

Fix loading structs into params via an offset pointer.
...
For certain values of "fix" :/. The code is ugly, but it does the right
thing: calculate the effect address and use the resulting pointer in a
move instruction.

Handle null string pointers.
2011-02-14 23:10:45 +09:00

Treat small structs as integers (disabled).

This is more to stash away a potential optimization. I need to fix the
real problem first.

Put another bandaid on the type creation system.
...
It seems that building types is very fragile: all too easy to fix things
in one place and break something somewhere else. I guess the type system
will need a comlete rewrite at some stage.

Fix some problems found by the new qfcc.
...
With this, ruamoko/lib almost compiles (though no object files are output).
Just some bogus "redeclared" errors and an improperly implemented
statement that produces an ice.
2011-02-14 23:10:45 +09:00

Work around a warning about passing int constants into ...
...
I'm not sure why this is happening now when it didn't in the old qfcc,
but this will take care of the warning for now until I can get around to
fixing it.

And fix build_struct for built-in struct types.
...
The previous fix broke builtin structs (eg, @param). Calling find_type()
for built-in structs has proven to be a bad idea :)
2011-02-13 21:07:22 +09:00
a19b7ec8f9
Make struct decls actually work.
...
find_type() does type comparisons based on tag name for struct/union/enum
but when it returns the previous tag (eg, from "struct foo;") the returned
type has a null symtab pointer, so setting the symtab pointer in the type
before calling find_type() only throws away the symtab. Thus, since
find_type() doesn't check the symtab pointer when comparing the types, set
the symtab pointer after calling find_type().

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.

Handle @self and @this correctly.

Allow (void) qc-style functions.
2011-02-13 17:37:11 +09:00
d75c35ba30
Allow qc style function params.
...
Due to ambiguities in the grammar, qc-style function params and c-style
function params had to be completely separated. This means that qc-style
functions can not use pointers and must use qc-style function declarations
for parameters, and c-style functions must use c-style param declarations.
While this rule is tedious for converting the Ruamoko library, it does
actually make for a more consistent language.

Add a class type to symbols and rework the CLASS_NAME handling.

Rename ReuseConstant to emit_value and use emit_value to emit any non-short

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.

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.
