The big type-system rewrite. Horribly broken :)
...
While broken, it is good enough to compile modulo.r.
This gives qfcc C's type system with QC specifics bolted on top (rather
than trying to cram C's type system into QC's). Pointers and arrays now
use C syntax and semantics (though I think there's a lot of breakage in
there at the moment). Functions themselves are still dual mode: both QC
style and C style are available.

Get qfcc running again.
...
It segs when it tries to link, but that's because a real object file has
not been created yet. However, I can get my tree and flow diagrams :)

Add a missing break.
...
"return" falling through to "goto" was bad news :)

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

Produce flow diagrams of the basic blocks.

Use function pointer tables instead of switch.
...
This seems to be better for complicated code. switch seems to be better
suited for relatively simple code.

Break out print_expr into its own file.

Possibly get vector calls working.

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).

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

Make operator type overrides clear.

Get calls mostly working.
...
Bind seems to be broken, but parameters seem to be being set correctly.

Minor tweaks of the expression tree output.

Implement bind expressions.

Temp expressions now use operands instead of defs.
2011-01-21 11:26:43 +09:00
Bill Currie
2998e578fb
Get very basic deref assignments working.
...
More complicated expressions will not work yet.

Handle block sub-expressions that produce results.

Allow the operand to override the symbol's type.
2011-01-21 10:56:32 +09:00

Get a lot of statements being generated.

Move the statement printing near the top of the file.
2011-01-20 18:07:24 +09:00

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

Slight improvement to branch instruction nodes/labels.

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.

Get the label from the right expression.

Clean out ex_def as ex_symbol replaces it.
