9f6dcec9dd --save-temps support for qfcc. It'll leave files with the same filenames 
they're generated from, with the exception that they will have an
extension of .p. Obviously, depends on cpp support.

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:
	o	better control over whether case ranges are built
	o	/always/ append the temp = test expression and use temp instead of
		test for the != check
	o	only ever build case ranges if the switch expression is integer
 2001-11-14 06:45:31 +00:00

da36feff7f oops, failed to notice that relocs on temp defs weren't being done correctly 
memset wasn't such a good idea :P
 2001-11-13 23:21:23 +00:00
Bill Currie
cfa47717c6 expr.c: 
once again, temp def ref counts seem to be correct

Bill Currie
f2f8e096f3 qfcc.h: 
o	add a "freed" marker to def_t to prevent double freeing of
		temp def offsets
emit.c:
	o	break out the bind code into emit_bind_expr (doesn't /really/
		emit code, but still:)
	o	make bind work with disparate types (forces def_t->freed 1)
pr_def.c:
	o	mark array pointers as initialized and constant.
	o	don't free the offset for already freed temp defs
pr_imm.c
	o	fix a bug in uinteger support

cb4ce6a634 remove the default label from the switch label table while fetching it. 2001-11-06 20:39:42 +00:00
Bill Currie
13a177f217 use 'b' (bind) instead of '=' (assign) for switch's test temp def so simple 
expressions (ie, just a def) don't generated wasted assignments and clean up
switch's debug info so you get the switch line rather than the line for the
closing }
 2001-11-05 19:12:33 +00:00
Bill Currie
9b784e331b remove '(' (never used, don't remember what it was intended for) and add 
'b' (bind), 's' (state) and 'c' (call) to get_op_string.
 2001-11-05 19:11:03 +00:00

5f5060cbf0 move the users and used setting code from emit_statement to 
PR_AddStatementRef. This removes essentially duplicate code and 3 ifs :)

b499d7e1e8 I've decided that shuffling the `sections' like that doesn't really gain 
anything, so I'm reverting that change.
 2001-10-31 17:55:35 +00:00
Bill Currie
3b2d2a1c88 re-arrange the order of the `sections' of a .dat file to match the header 
order. this also `happens' to put the strings section just before the globals
section (both at the end) which will make pointer bounds checking easier.

b07d60f6d6 add getopt.c and getopt1.c to the makefile. There is preprocessor 
stuff in these files to detect when they need to be compiled, so they
don't need anything in configure.

5cbd50d835 count the number of digits needed rather than relying on -lm (now it's not

f8a41cb1bc completely nuke the concept of "priority" from opcodes and use get_op_string

Bill Currie
133ce647fb implement break and continue. only loops covered for now, but that's because

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
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.

dcb51dc586 expr.h: 
get_type and extract_type prototypes and add extern for type_names
emit.c:
	use extract_type instead of get_type
expr.c:
	get_type now returns the type pointer rather than the qc type enum.
	extract_type uses get_type to return the qc type enum.
	make type_names global
	use get_type instead of ex_expr/ex_def to cover more cases
	clean up function call/return processing as a result of get_type
pr_opcode.c:
	use opcode_priority_type_table_ab when var_c is null and a minor
	cleanup in PR_Opcode_Find
