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

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

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.

87ce9f5333 Get basic function creation working.
Even more FIXMEs, but the pascal parser can now create functions. The
function records even get emitted.

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.

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.

21d7c78eb7 Allow deep copying of expression trees.
Certain expression types (eg labels) are created fresh.

abe471110c Make inc/dec_users return the the expression.
Just for convenience.

18ae178eaf Make new_vector_expr and new_quaternion_expr const-correct. 2011-01-11 08:43:34 +09:00

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.

a4635d79e8 Slightly more informative error locations.
Inside a class or protocol definition is not "at top level" ;)

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.

d981968208 v6 modulo implementation now produces good code.
At least for simple inputs, anyway. That needs to be tested next.

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.

997102fea8 audit the usage of "only"
There are still a few iffy places (notably around certain prepositions), but
the relevant sentences are now much easier to read.

There are probably other situations, but I'll fix them as they show up.
