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.

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.

cfdc2e5d6b Complete the documentation for relocations.
This covers only in-memory storage of relocation records, not object file
relocations.

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.

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.

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.

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.

1f8b453d58 Add some return statments for now.
At the moment, qfcc has no way of knowing that a function will never
return. This is needed until the time qfcc can know that.

Yay, I've wanted this feature in qfcc for many years :).

adeef4a4eb Copy named expressions.
Since expressions can be modified, making DAGs this early causes
corruption of the expression tree.

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.

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).

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.

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.

81125cff3a 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.
