Bill Currie 0c58cd9067 Generate only one daglabel for value operands.
As each value is now unique, their labels can also be unique, which will
improve CSE.

Bill Currie 28ce35f1c1 Make values independent objects.
values are now uniquely allocated (for the current object file). With
this, constants in dags will work.

Bill Currie 9095e1eabc Rework build_switch to use initialize_def.
This required support for label reference expressions, whose purpose is to
represent the address of a label.

Bill Currie bc1b483525 Nuke the rcsid stuff.
It's pretty useless in git.

Bill Currie d910c14935 Clean up some doxygen warnings. 2011-07-10 19:12:07 +09:00
Bill Currie 55cc0f9206 Bring back the unsigned type (PROGS version bump)
This is only low-level support (the unsigned keyword still does not work),
but sufficient to make switch statements using jump tables work.

Bill Currie 39278ba8cc Explicitly select between direct and indirect moves. 2011-03-09 10:30:57 +09:00
Bill Currie 8cfa80b5d4 Implement think expressions. 2011-03-05 18:01:37 +09:00
Bill Currie c5ecc170b6 Give labels a usage count to detect unused labels. 2011-03-03 15:28:49 +09:00
Bill Currie 45de7327dc Implement alias expressions (finally).
Alias expressions are like cast expressions, but never do any conversions.
2011-03-03 11:06:10 +09:00
Bill Currie 19f6faf0ad Fix aggregate initializers.
Initializing arrays and structs seems to be working.

Bill Currie d162838299 Resurrect constant_expr(). 2011-02-15 09:28:27 +09:00
Bill Currie 681ded9375 Fix debug line number information. 2011-02-09 09:59:43 +09:00
Bill Currie 3c849b970b Handle union access now that they're detected properly. 2011-02-08 14:45:48 +09:00
Bill Currie 28ba4b5712 Correct a comment. 2011-02-07 09:56:33 +09:00
Bill Currie 67957a14df Bring back convert_name(), but siimplified.
It is now mainly for converting __FILE__ etc, handling expression symbols,
and checking for undefined identifiers.
2011-02-06 14:29:14 +09:00
Bill Currie a6e65488ec Remove the "test" parameter from test_expr.
The parameter became redundant at some stage.
2011-01-27 08:31:51 +09:00
Bill Currie 0624408317 Move the diagnostic functions into their own file. 2011-01-24 21:54:57 +09:00
Bill Currie afc5b2827d Simplify def handling, use far data.
Since there is now a proper symbol table, defs are now just references to
memory locations and the symbol table takes care of duplicates.

Also, start using far data for ObjQC structures.

The qfo functions have been stubbed out until I figure out what to do with
object files in the new scheme.

Bill Currie 341f370662 Rename is_math() to is_math_op(). 2011-01-23 11:12:05 +09:00
Bill Currie d5f669af7a Nuke temp reference counting.
The whole reason for this crazy developement branch :)
2011-01-22 11:40:53 +09:00
Bill Currie 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).
2011-01-21 19:07:58 +09:00
Bill Currie 4a24393d8d Temp expressions now use operands instead of defs. 2011-01-21 11:26:43 +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.
2011-01-20 15:23:19 +09:00
Bill Currie 5deda9c9b9 Clean out ex_def as ex_symbol replaces it. 2011-01-19 22:25:04 +09:00
Bill Currie b5424bca7d Start work on getting expressions converted to internal statements. 2011-01-19 15:47:45 +09:00
Bill Currie e08efe036b Move the constant expression values into their own struct. 2011-01-19 08:43:24 +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.

Bill Currie 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.

Bill Currie 258c896e4d Create a function to build if/else blocks. 2011-01-13 14:33:16 +09:00
Bill Currie 21d7c78eb7 Allow deep copying of expression trees.
Certain expression types (eg labels) are created fresh.
2011-01-11 12:05:29 +09:00
Bill Currie 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 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.

Bill Currie 40fefff847 fix incorrect users for temps resulting from casting the result of ?:
There are probably other situations, but I'll fix them as they show up.

Bill Currie 66257e3a88 run in fear, function overloading is here
This is an imperfect revision of history.

Bill Currie 4d044bfea4 make entity.vector.x work properly by making relative field offset work. also don't emit a field def for the resulting immediate
This is an imperfect revision of history.

Bill Currie 7b28c555ba quaternion field access now works 2004-04-09 04:12:44 +00:00
Bill Currie c3f41e3e69 new opcode: state.f. same as state, but takes a 3rd float operand to
specify the step for calculating nextthink. accessed using
[frame, think, step] (state is [frame, think])
2004-02-11 01:43:33 +00:00
Bill Currie 51b0a66ac7 better constant folding with auto-conversion between scalar types (might
make that optional for non-constants)
2004-01-25 08:55:03 +00:00
Bill Currie 945006494f short circuit logic for && and || (as per C). forces standard precedence
(ie, breaks --traditional) when enabled (no choice at the moment, next fix)
