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.

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.

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.

This makes problem reporting more informative.

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.

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).

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.

8f71986306 Add symbol expressions (like def expressions).
They will eventually replace def expressions. Currently quite broken.

008f4e1929 Don't return .return in advanced mode. 2011-01-13 14:50:25 +09:00

638f4445cc More return code cleanup.
Don't use the true void return in traditional mode.
Prefer the true void return over "done" at the end of functions.
Don't emit the above if the last emitted statement is a return and there is
no label at the end of the function.

3c9991364b Add a "void return" instruction.
I got fed up with always having to explicty return something.

96ba4605fa Fix the micro-optimization that avoided emitting x = x
The check was broken by alias defs. If a def is aliased, the alias must be
checked.

4da2657bfe Fix most of the notice spam (hacky).
The implementation and declaration of OP_DONE disagree (not sure what to do
about it yet), so give it special treatment when emitting.

75ec6bf244 Clean out some unnecessary types from the progs engine and clean up the mess.
This is a nasty commit, sorry, but 99% of the commit is interdependent.

f7df6fea17 instead of having cpp args in progs.src, potentially breaking some mods, generate progs.i as a series of #includes and then compile everything in one pass 2006-05-24 14:35:39 +00:00

762aefc9b1 implement Raven's calling convention (rcall: first 2 params in opb and
opc). should give a general speedup to most progs.
