c1753046a9 start on actually generating code. doesn't work yet (getting a weird type
redeclaration error and not all expressions are handled yet).

e99796c4cf new expression type: ex_block. forms a linked list of expressions for fast
appending and ease of manipulation.

90b5c57266 fix lost initial char of string constants
make expression strings char * instead of string_t (don't put them into
pr_strings prematurely);

53b66ef2e0 better label handling and strings are now completely parsed (including escapes) 2001-06-25 22:11:20 +00:00

1779a124c5 expr.h:
nuke the ex_statement and estatement_[st] stuff
	add label_expr prototype
expr.c:
	ex_statement nukage
	correct new_expr's decl
	add label_expr to ease label creation
	don't crash when printing a null expression (bare return)
qc-parse.y:
	estatement_t nukage
	statement statements and statement_block are type expr
	generate `expressions' for statements

a full parse tree for each function is now generated. there are several
special expression opcodes for statements:
	d	done    \
	r	return  -> unary: expression to return or null
	i	if      binary:   evaluated expression, destination label
	n	ifnot   binary:   evaluated expression, destination label
	c	call    binary:   function def, args (expr list, rev order)
	s	state   binary:   frame const, function def
	g	goto    unary:    destination label
	l	label   unary:    label number
in a top level expression, l (label) defines the label, otherwise it is a
reference.

ab051248e8 expr.h:
add prototype for print_expr
expr.c:
	add print_expr
	correct string accessors
	currect the result type for unary operators
qc-lex.l:
	correct string, vector and quaternion parsing
qc-parse.y:
	precedence corrections and more function scope work

CustomTF gets through the parsing again.

aac91d8cd6 more expression handling. turns out I'm mis-parsing field types, so that's next 2001-06-20 21:18:04 +00:00

56aafce20c qfcc.h:
rearrange def_t a little and add def_next (leaving next free for other
	uses)
pr_def.c:
	use def_next instead of next to link /all/ of the named defs
qfcc.c:
	ditto

bbc97079e0 pr_comp.h:
define PROG_ID_VERSION as 6 and redefine PROG_VERSION as 0x00fff001
	(0.fff.001) for the new qc features.
pr_edict.c:
	support version 6 and version 0.fff.001 progs
qfcc.h:
	add version field to options_t
	add min_version field to opcode_t
pr_opcode.c:
	set the minumum version of each opcode (gee, that table is getting ugly)
	filter out opcodes with too high a min_version when initializing the opcode
	hash tables.
qfcc.c:
	update help output.
	accept --id to limit code generation to id compatable (ver 6) progs.
	default progs generation to 0.fff.001

7ef4c2776e Immidiate sharing now /works/ (shaved off two pr_globals from CustomTF, too:).
Detect assignments to initialized globals and give an error, unless the --cow
(copy on write) option is given, and then allocate a new global for the var,
clear its initialized flag.
Relocate all globals.

bbb37d0080 customTF is now down to 4989 pr_globals. all parameters, local veriables and
termporary variables sit in one pool of memory (at the end of the globals)
thus drasticly reducing globals requirements. This works because the whole
lot is declared to be in the function's local variable space which is copied
to the locals stack in the progs engine.

a26f799de4 allocate temps based on size rather than type (get better re-usage this way)
put temps onto the local scope.

17e19f3892 regain about 5000 globals for customTF, but this fixes possible breakage with
premature temp var re-usage (ie, it puts the temps back into the locals space).

e090f3c9e3 do proper temp def handling so we don'e use any where near as many defs for
temporary variables (customTF went from 35941 to 12587 pr_globals).

e339e82c01 hash.h is now const correct as is a lot of qfcc 2001-06-04 04:52:14 +00:00

ddcd172a03 re-write the opcode selection to be a hash table lookup and statment generation
to get the opcode from the table record rather than the location within the
table (ewww). gives a nice speed boost /and/ makes the opcode table easier to
maintain.

09118bc01e pr_comp.h:
add OP_ADD_S. WARNING!!! this /will/ move.
progs.h:
	add prototype for PR_PrintStatement
pr_edict.c:
	add OP_ADD_S support in the progs checker
pr_exec.c:
	implement OP_ADD_S
tools/qfcc/include/.gitignore:
	add config.h.in
qfcc.h:
	nuke PR_NameImmediate and change PR_ParseImmediate's prototype (see
	pr_imm.c)
pr_comp.c:
	add ADD_S, adjust for PR_ParseImmediate's prototype, make
	PR_ParseExpression work with non-sequential opcodes (slow, will work on
	that next). Fix up initialised global parsing.
pr_imm.c:
	nuke PR_NameImmediate. didn't work well and wasn't such a good idea anyway.
	PR_ParseImmediate now accepts a def_t * arg. if null, will allocate a
	new global def, otherwise it will initialize the def passed in.
qwaq/main.c:
	sports some debugging code (dumps info about the progs it's running)
qwaq/main.qc:
	better ADD_S testing

02b09f4e5c no more redundant strings. costs ~7ms, though, but HALVING the strofs size
in frikbot seems worth it.

59e55834ed Another massive speadup caused by using hash tables to lookup already
generated immediate values. frikbot now compiles in just over 1s on my
machine.

43ea8f4fc0 Rip out I_FloatTime from cmdlib.
Use Sys_DoubleTime instead of I_FloatTime and print out ms for compilation

ec16ffaa65 move to using hash tables for variable lookups.
WARNING: this fixes a scope bug in qcc and thus you WILL get different (but
now correct) code for the following:

float foo;

void () bar =
{
	local float foo;
	foo = 0;
}

ie, the local foo will, as is correct, now be a separate var to the global
foo.

cb5c262ffc qtypes.h:
remove includes of qdefs.h and compat.h
pr_comp.h:
	merge pr_comp.h from quake and qfcc, removing the copy in qfcc
cmdlib.[ch]:
	nuke the endian code.
qendian.c:
	initialise the LittleLong etc pointers at compile time rather than run
	time
com.c (both nq and qw):
	nuke the LittleLong etc init code
everything else:
	fix up after the qtypes.h cleanup

2dd03876af QFCC -- the QuakeForge Code Compiler -- an autoconfiscated qcc.
It sucks, but it works, and will form the basis for something that Does
Not Suck.
