locals.

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? :/

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
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.

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.

ae98ed8603 field types are parsed correctly, but parameters have been lost for the

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

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
