0f5f68623f it's as broken as all-get-out, but object files can now be linked 2002-07-11 22:38:23 +00:00

24e242ed35 move the type strings into their own string pool so the progs strings don't 
get cluttered

46bad45c7a move s_file, pr_source_line and pr_error_count into pr, make the linker 
errors more meaningful, and fix a blasted string.h issue (damn old gcc;P)

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

f90f78990a ok, I'm happy with this now (bit fields anent' so great for portable file 
formats:/)
 2002-06-18 21:00:41 +00:00

331df31f6a get the function number early so things don't get mixed up when new functions 
get created while parsing a function

f7d8c2968f better global (and other space) def re-use 2002-06-10 23:14:32 +00:00

1e57351be1 there, no more PR_* functions or pr_* files :) 2002-06-09 04:30:02 +00:00

Bill Currie
e17604f9c2 remove all arbitrary limits except for globals. they'll need a little more 
work. Once they're done, it should take quite a big mod to crash qfcc due
to too many strings/statements/etc :)
