fix a silly stanfu with goto
qc-parse.y:
	suffle the debug code
2001-06-27 05:45:20 +00:00
Bill Currie 673e6e66b7 turns out qcc wasn't so stupid about = vs ||/&& precedence after all (just
my interpretation of the code was:/) why oh why didn't John use bison or yacc
in the first place? :/

Bill Currie d783a024b3 record an expression's line number and file and sort of handle state
expressions
2001-06-26 16:23:21 +00:00
Bill Currie 3242c04798 fix the redef error 2001-06-26 16:12:01 +00:00
Bill Currie c1753046a9 start on actually generating code. doesn't work yet (getting a weird type
redeclaration error and not all expressions are handled yet).
2001-06-26 07:21:20 +00:00
Bill Currie e99796c4cf new expression type: ex_block. forms a linked list of expressions for fast
appending and ease of manipulation.

Bill Currie 749d460041 duplicate code cleanup 2001-06-26 02:46:02 +00:00
Bill Currie 3fa3ab59a9 clean up error reporting a little 2001-06-25 23:42:49 +00:00
Bill Currie 625915288c hopefully make line directives work 2001-06-25 23:38:32 +00:00
Bill Currie 90b5c57266 fix lost initial char of string constants
make expression strings char * instead of string_t (don't put them into
pr_strings prematurely);
2001-06-25 22:53:15 +00:00
Bill Currie 53b66ef2e0 better label handling and strings are now completely parsed (including escapes) 2001-06-25 22:11:20 +00:00
Bill Currie 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.

Bill Currie 2d87eeb57d functions are now initialized, but no code is yet generated 2001-06-25 18:23:29 +00:00
Bill Currie df897255ff make usage of the new parser easier to configure 2001-06-25 18:22:53 +00:00
Bill Currie 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.

Bill Currie c12ac3278e a little progress on functions 2001-06-21 07:08:34 +00:00
Bill Currie ae98ed8603 field types are parsed correctly, but parameters have been lost for the
moment
2001-06-20 23:32:13 +00:00
Bill Currie aac91d8cd6 more expression handling. turns out I'm mis-parsing field types, so that's next 2001-06-20 21:18:04 +00:00
Jeff Teunissen ba17807833 whitespace. 2001-06-20 19:53:37 +00:00

Bill Currie 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

Bill Currie 327e95a3c8 gcc 3.0 fixes 2001-06-20 02:07:20 +00:00
Bill Currie 90a0cdfedf now seems to get through CustomTF properly, but better def handling is needed 2001-06-19 23:35:09 +00:00
Adam Olsen 67e4fa85bf add support for \<, \>, and \^ to qfcc. \< bolds all characters (toggles bold really) until \>, and \^ bolds (toggles) the next character. 2001-06-19 23:27:07 +00:00
Bill Currie 20bf698330 fix \x handling for 0-9 2001-06-19 22:26:16 +00:00
Bill Currie f50ce04ccb d'oh, forgot to add 10 for a-f and A-F 2001-06-19 22:13:35 +00:00
