Ensure alias operands are never nested.
...
No more than one level of aliasing is ever needed, so strip off any
intervening aliases that show up.

Use value for pointer operands.
...
This allows daglabels on pointer operands without a redundant daglabel
pointer.

Make values independent objects.
...
values are now uniquely allocated (for the current object file). With
this, constants in dags will work.

Fix the source of alias def chains.
...
The actual bug might still be elsewhere, but at least now I know the alias
chains were coming from accessing .return and .param_N, which are unions
(not directly usable by the progs engine). Emitting a reference to a union
(or struct) would create an alias def, but an alias expression was created
in the expression tree to simplify return/param access. The double layer
(sometimes 3 or 4) alias isn't really neaded, so rather than layering the
aliases, just re-alias the alaised def.

Nuke the rcsid stuff.

It's pretty useless in git.

8d3508cf20
Allocate space for temp defs using size rather than type.
...
Statement operands throw away the high level type information, so store
type size in the operand and use this size for allocating space for temps
rather than using the low-level type.

Fix constant value type handling.

Rename immediate.[ch] to value.[ch] and clean up the mess.

02a70ebe1c
Remove the auxfunction manipulation from the compiler proper.
...
It was broken code in the first place (realloc and pointers), and is
redundant with the new linking process.

Bring back the offset alias support.

Accidently nuked it when fixing .return etc.

Create and use alias operands for alias expressions.
...
This avoids the alias expression modifying the operand used in other
expressions.

9c9a71f1af
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.
2011-02-15 22:55:15 +09:00

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.

The fix for pointers broke constants (particularly, enums). Oops.

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
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.

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.

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.

The first function seems to work fine, but there's a problems with the

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.

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.

The implementation and declaration of OP_DONE disagree (not sure what to do
