96fae582e3
Implement bind expressions.
2011-01-21 11:27:40 +09:00
4a24393d8d
Temp expressions now use operands instead of defs.
2011-01-21 11:26:43 +09:00
2998e578fb
Get very basic deref assignments working.
...
More complicated expressions will not work yet.
2011-01-21 10:59:16 +09:00
ff6e2584da
Handle block sub-expressions that produce results.
2011-01-21 10:57:47 +09:00
16e013ff5d
Allow the operand to override the symbol's type.
2011-01-21 10:56:32 +09:00
3f2793ef72
Get a lot of statements being generated.
2011-01-20 23:26:13 +09:00
e45ea4b2ae
Move the statement printing near the top of the file.
2011-01-20 18:07:24 +09:00
35b7278967
Re-disable the next-edge constraints.
...
This gives a flatter layout.
2011-01-20 15:36:10 +09:00
08e387ebac
Slight improvement to branch instruction nodes/labels.
2011-01-20 15:33:13 +09:00
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.
2011-01-20 15:23:19 +09:00
0594609b3a
Get the label from the right expression.
2011-01-19 22:25:43 +09:00
5deda9c9b9
Clean out ex_def as ex_symbol replaces it.
2011-01-19 22:25:04 +09:00
b5424bca7d
Start work on getting expressions converted to internal statements.
2011-01-19 15:47:45 +09:00
cac2e04b18
Avoid namespace issues with dstatements.
2011-01-19 11:35:34 +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
ff6e1b4d6c
Get functions attempting to generate code.
...
However, the statements are only printed as expressions.
2011-01-19 08:38:09 +09:00
33db650161
Add QuatInverse to calculate 1/q.
...
There's still no direct quaternion division because I don't know if the
definition of q1/q2 is (1/q2)*q1 or q1*(1/q2) (it does make a difference).
2011-01-18 22:22:18 +09:00
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
8fb1b49a9d
Add support for function symbols.
2011-01-18 10:46:42 +09:00
b186173d18
Fix a segfault in structure finalization.
2011-01-18 08:59:44 +09:00
21c0c960ae
Initialize data before types.
...
This is needed for string data. It might be better to init saved strings
separately, but this works for now.
2011-01-18 08:58:43 +09:00
3fe7a7250a
Handle unnamed structures in make_structure.
...
Symbols may not have null names.
2011-01-18 08:56:47 +09:00
b76a5c5284
Add my QuakePascal test program.
...
Trivial as it is...
2011-01-17 22:44:58 +09:00
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.
2011-01-17 22:34:41 +09:00
85de101aa3
Break out the defspace code.
...
This also makes some improvements to the free block handling code.
2011-01-17 22:34:41 +09:00
d3a98af783
Make internal_error globally available.
2011-01-17 22:34:41 +09:00
537b930ba6
Add new_symbol_type to ease creation of typed symbols.
...
This is inteded for code generation functions that need to create
variables and structures.
2011-01-17 12:04:41 +09:00
ffea505678
Cleanup QC's constant handling based on QP.
2011-01-14 12:10:28 +09:00
c38ea0b1bc
Correct the spelling of "nil".
2011-01-14 12:07:40 +09:00
fb8b3d1211
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
8f71986306
Add symbol expressions (like def expressions).
...
They will eventually replace def expressions. Currently quite broken.
2011-01-13 14:54:24 +09:00
008f4e1929
Don't return .return in advanced mode.
2011-01-13 14:50:25 +09:00
5b8725ca66
Rewrite the symbol (table) management in light of actual usage.
2011-01-13 14:48:38 +09:00
ac14db7b1b
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.
2011-01-13 14:45:53 +09:00
258c896e4d
Create a function to build if/else blocks.
2011-01-13 14:33:16 +09:00
638f4445cc
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
3c9991364b
Add a "void return" instruction.
...
I got fed up with always having to explicty return something.
2011-01-13 00:29:56 +09:00
9ce9b70484
Add variadic functions.
...
Already extending QuakePascal, and many basics aren't there yet :P
2011-01-12 23:39:59 +09:00
02b3dde83b
Make QuakePascal programs runnable.
...
Generate a mini-main function (".main", to avoid namespace pollution) that
calls the function named by "program", and make qwaq check for ".main" as
well as "main". If both are present, ".main" will take priority.
2011-01-12 23:39:22 +09:00
332b7da127
Minor header cleanup.
2011-01-12 23:34:15 +09:00
96ba4605fa
Fix the micro-optimization that avoided emitting x = x
...
The check was broken by alias defs. If a def is aliased, the alias must be
checked.
2011-01-12 23:33:51 +09:00
c787923c99
Forgot to remove that print_expr.
2011-01-11 12:11:54 +09:00
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
c73ac30e3f
Turns out decrementing the users was very very bad.
2011-01-11 10:56:36 +09:00
099eb2d31c
Ignore the new files.
2011-01-11 09:08:27 +09:00
4af5dad424
More math identities.
...
I forgot about 0 for multiplication and division. Detects division by zero.
2011-01-11 08:49:43 +09:00
5b43fc1de3
Improve interaction between temps and const_folding.
...
Unfortunately, this seems to overdo the decrementing, so it could be
dangerous, but the ruamoko directory builds properly.
