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 :)

The whole reason for this crazy developement branch :)

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.

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.

Bind seems to be broken, but parameters seem to be being set correctly.

Minor tweaks of the expression tree output.

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.

However, the statements are only printed as expressions.

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

Add support for function symbols.

Initialize data before types.

This is needed for string data. It might be better to init saved strings
separately, but this works for now.

Add my QuakePascal test program.

Trivial as it is...

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.
2011-01-17 22:34:41 +09:00
Bill Currie

Break out the defspace code.

This also makes some improvements to the free block handling code.

Add new_symbol_type to ease creation of typed symbols.
...
This is inteded for code generation functions that need to create
variables and structures.

Rework the lexer and parser to use symbols instead of defs.
...
Currently parses the test program just fine, but code generation is very
very broken.
2011-01-13 14:58:16 +09:00
Bill Currie
8f71986306
Add symbol expressions (like def expressions).
...
They will eventually replace def expressions. Currently quite broken.

Create a function to ease param list building.
...
This is especially useful for QuakePascal, but it will mean I'll be able to
get rid of the parameter reversals in Ruamoko later 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.
2011-01-13 00:46:46 +09:00
Bill Currie

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