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

broken.

928d343295 pr_comp.h:
o	add ev_uniteger to the types enum
	o	add opcodes for ifbe, ifb, ifae, ifa, jump, lt.ui, gt.ui, le.ui, ge.ui
progs.h:
	o	add uinteger accessors
pr_exec.c:
	o	implement ifbe, ifb, ifae, ifa, jump, lt.ui, gt.ui, le.ui, ge.ui

expr.h:
	o	prototype inc_users
qfcc.h:
	o	add externs for op_ifbe, op_ifb, op_ifae and op_ifa
emit.c:
	o	don't bother emiting an assignment to a temp def that's only used once
		(ie, it's never read, only written to)
	o	support the new if* instructions
expr.c:
	o	support the new if* insructions
	o	dectect expression loops in append_expr
	o	support unsigned integers
	o	re-work temp def usage counting
pr_def.c

f029687ff0 switch statement. could do with lots of improvements, but this should be a
good start.

3bba5398ba - audit malloc usage. now everything checks the return value :) 2001-10-24 22:50:06 +00:00

133ce647fb implement break and continue. only loops covered for now, but that's because
switch isn't implemented yet

237d238a65 beginnings of "if" uninitialized variable support. doesn't make any
difference yet

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.
--undefined-function-warning is now --no-undefined-function-warning and
the default is to detect called but undefined functions.

79ac85b54f type checking now works much better and there is now a NIL builtin constant
which can be assigned (/only/) to anything.
