8ddce20949 pr_*: add storep.p so pointers can be stored into entities
emit.c: convert & (address) to . in unary .
        rewrite emit_assign_expr
expr.c: remove debug code and make unary . less agressive on address calcs
        also convert & (address) to . for lvals

00b2a45ecd change the operator for "address" from "." to "&" so load.p can be implement.
this makes it so pointers in entities work.

7d9266a3f0 beginnings of array support. no array initialization yet and foo[i] = bar is

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

da36feff7f oops, failed to notice that relocs on temp defs weren't being done correctly
memset wasn't such a good idea :P

cfa47717c6 expr.c:
once again, temp def ref counts seem to be correct

f2f8e096f3 qfcc.h:
o	add a "freed" marker to def_t to prevent double freeing of
		temp def offsets

	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)

	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

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 }

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.

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.

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.
