d5f669af7a Nuke temp reference counting.
The whole reason for this crazy developement branch :)

2f09efe547 Break out print_expr into its own file. 2011-01-21 20:31:40 +09:00

52b561f7cb Nuke bind expressions.
Since I'm planning on implementing CSE and other optimizations, they're
rather redundant (and I'm having trouble getting them to work).

0d01930056 Link a bool to its block rather than the block's head.
This makes the flow make a little more sense.

5c5fa67e43 Minor tweaks of the expression tree output. 2011-01-21 15:34:42 +09:00

35b7278967 Re-disable the next-edge constraints.
This gives a flatter layout.

08e387ebac Slight improvement to branch instruction nodes/labels. 2011-01-20 15:33:13 +09:00
Bill Currie
f8cc347dce Print expressions as dot files.
While the resulting images can be a little confusing, they're much easier
to read than my cryptic postfix notation.

b5424bca7d Start work on getting expressions converted to internal statements. 2011-01-19 15:47:45 +09:00

f2ef24d0cc Make symbols use the new value struct for constants. 2011-01-19 11:09:54 +09:00

e08efe036b Move the constant expression values into their own struct. 2011-01-19 08:43:24 +09:00
Bill Currie
87ce9f5333 Get basic function creation working.
Even more FIXMEs, but the pascal parser can now create functions. The
function records even get emitted.
2011-01-18 12:47:13 +09:00
Bill Currie
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.

d3a98af783 Make internal_error globally available. 2011-01-17 22:34:41 +09:00
Bill Currie
8f71986306 Add symbol expressions (like def expressions).
They will eventually replace def expressions. Currently quite broken.

c787923c99 Forgot to remove that print_expr. 2011-01-11 12:11:54 +09:00
Bill Currie
08bf7e24de Produce nicer code for post-op.
The temp notice is still there for arrays (that's caused by issues in
constfold.c, not easily fixilbe), but it's harmless and correct (and nice)
code is much more important.
2011-01-11 12:07:48 +09:00

ad787ae98a Set the expression type to the correct value for addresses. 2011-01-11 12:06:40 +09:00

21d7c78eb7 Allow deep copying of expression trees.
Certain expression types (eg labels) are created fresh.
2011-01-11 12:05:29 +09:00

abe471110c Make inc/dec_users return the the expression.
Just for convenience.
2011-01-11 08:44:43 +09:00
Bill Currie
18ae178eaf Make new_vector_expr and new_quaternion_expr const-correct. 2011-01-11 08:43:34 +09:00
Bill Currie
cd38bd71fa Swap the order of scale and base for calculating the array index.
fold_constants doesn't like dags very much, but it can do the right thing
if the expressions are in the right order. This is merely a workaround
until I get to work on the code generator itself.

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.

2011-01-03 16:25:29 +09:00

530e8fae34 Rework class_type_t to be more useful.
This allows current_class to refer to procols as well (for error
reporting).

52e844ee48 Produce slightly better v6 modulo code for complex inputs.
I'm having problems with temp defs, but I imagine this code is rarely used
so I won't worry about it for now. It will, however, make a good test case
for when I rework emit.c after I do some reading.
2010-12-19 11:23:33 +09:00
Bill Currie
d981968208 v6 modulo implementation now produces good code.
At least for simple inputs, anyway. That needs to be tested next.
2010-12-18 22:21:55 +09:00
Bill Currie
00e50c0ad3 Rewrite the v6 modulo implementation.
While trying to understand bind expressions, I discovered that the v6
modulo code was incorrect. This version is correct but uses one too many
temps. That's next.

the relevant sentences are now much easier to read.

dcb51dc586 expr.h:
get_type and extract_type prototypes and add extern for type_names
emit.c:
	use extract_type instead of get_type
expr.c:
	get_type now returns the type pointer rather than the qc type enum.
	extract_type uses get_type to return the qc type enum.
	make type_names global
	use get_type instead of ex_expr/ex_def to cover more cases
	clean up function call/return processing as a result of get_type
pr_opcode.c:
	use opcode_priority_type_table_ab when var_c is null and a minor
	cleanup in PR_Opcode_Find
