Add is_float ().

For now, it checks just floats, but I might one day add doubles.

Create and use alias operands for alias expressions.

Write the linker output to progs.dat.
...
There is much breakage, but qfcc now produces a progs.dat from either
progs.src or object files. Better yet, the progs.src result is passed
through the linker, removing much duplicate code.

Clean up objective-qc type encoding.
...
Structures etc now never encode the fields as well (I might revert that
at some time). Type parsing has been removed: it has proven unnecessary
and overly complicated, and the new qfo encoding should be more useful.
2011-02-18 20:51:04 +09:00
Bill Currie

Enhanced type encoding.
...
This creates a compact representation of types as seen by qfcc. This is
intended mainly for debuggers.

Create structures for new qfo format.

This breaks a lot of existing code, so that code has been commented out

Allow defs to specify use of offset relocations.
...
Access to struct fields in near data can be done using only one operand,
but offset relocs need to be used. However, as not all defs want offset
relocs, a flag has been added to the def struct.

Move method function defs into the far data space.
...
As they are never referenced directly by instructions, there's no need for
them to be in the near data space, taking precious def locations.

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.

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.
