d5b637ae06 first stab at implementing ObjC like features. The parser doesn't generate
any code for the new features yet (I need to learn more about how objc
/works/) but nothing seems to have been broken.

80723fdec7 o don't ice when ex_name or ex_nil expressions show up in emit_expr.
instead, treat as useless epxression.
 o  mark rvalue expressions as such
 o  increment the users of a managed temp def when in an rvalue expr

5ca785e7e8 uninitialized variable detection. not perfect (lots of false negatives, but
fewer than before;) but prozac isn't giving any false positives.

96e4e1a232 the beginning of unititialized var detection. first victim: functions.

the default is to detect called but undefined functions.

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.
