Bill Currie 05788e55e5 don't generate useless expression warnings when that expression was caused
by an error
2002-05-01 22:08:59 +00:00
Bill Currie 962dc8e46e rewrite the type and def parsing to allow more flexible types 2002-05-01 21:35:39 +00:00
Bill Currie 860e3ebb1d make unsigned arrays/pointers more useful by allowing them to be used as
unbounded arrays
2002-02-24 01:11:34 +00:00
Bill Currie 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

Bill Currie d1fcfd1939 Implement --traditional so qfcc can be a nicer qcc. This disables several
keywords (quaternion integer function for break continue switch case default
NIL struct enum typedef) and converts some errors to warnings (assignment to
constants, insufficient function arguments, return; from non-void function,
anal function `pointer' type checks)

Bill Currie cc34e5954f lots of work on better array/pointer/struct handline. doesn't quite work yet 2001-12-12 08:39:47 +00:00
Bill Currie 00b2a45ecd change the operator for "address" from "." to "&" so load.p can be implement.
this makes it so pointers in entities work.

Bill Currie 40d47e91cb win32 portability fixes 2001-11-15 03:54:35 +00:00
Bill Currie 7d9266a3f0 beginnings of array support. no array initialization yet and foo[i] = bar is
broken.
2001-11-15 00:46:36 +00:00
Bill Currie 3fe67eecd2 expr.c:
it helps if one understands /why/ something is done. I think this
	might be it for the reference count tweeks
switch.c:

Bill Currie 5ca785e7e8 uninitialized variable detection. not perfect (lots of false negatives, but
fewer than before;) but prozac isn't giving any false positives.
2001-10-18 20:05:26 +00:00
Bill Currie 79ac85b54f type checking now works much better and there is now a NIL builtin constant
