Bill Currie 52e844ee48 Produce slightly better v6 modulo code for complex inputs. 
I'm having problems with temp defs, but I imagine this code is rarely used
so I won't worry about it for now. It will, however, make a good test case
for when I rework emit.c after I do some reading.
 2010-12-19 11:23:33 +09:00
Bill Currie d981968208 v6 modulo implementation now produces good code. 
At least for simple inputs, anyway. That needs to be tested next.
 2010-12-18 22:21:55 +09:00
Bill Currie 00e50c0ad3 Rewrite the v6 modulo implementation. 
While trying to understand bind expressions, I discovered that the v6
modulo code was incorrect. This version is correct but uses one too many
temps. That's next.

Bill Currie 997102fea8 audit the usage of "only"

the relevant sentences are now much easier to read.

client_menu.[ch]:
	use the InputLine object instead of directly using the api
InputLine.r:
	builint functions are = #0, not = 0 :P
function.[ch]:
	provide copy_params
method.[ch]
	provide copy_keywordargs
expr.c:
	call inc_users for the parm temp if it's a bind expression
	revers a copy of the selector when building the selector name so the
	selector doesn't get mangled
qc-parse.y:
	catch erronous func = const inintializers (should be func = #const)

Bill Currie 102eab0d84 linker.[ch]: 
start working on the linker.
class.[ch]:
	redo class defs so the pointer works (needs relocs still)
obj_file.h:
	add prototype for read_obj_file, QFO_* data access macros and include
	pr_debug.h
type.[ch]:
	separate type system initialisation and recording of the standard types
	so find_type works properly in multiple compilation
def.c:
	don't mark static defs as initialized
expr.c:
	proper class pointer def stuff
immediate.c:
	clean out dead vars/code
obj_file.c:
	allocate space for the line info and bail if the file can't be opened.
qfcc.c:
	register the standard types for each compile pass and start linking the
	files
