77806f4b1b [qfcc] Get dag code generation mostly working
There's an ICE in return-ivar, but assignchain passes let alone builds.

16bda66785 [qfcc] Add more statement types for move/memset
They ease the statement checks between assign/move/memset and the
pointer versions (don't need all those strcmps)

3c2f6c8447 [qfcc] Simplify flow_analyize_pointer_operand
and its usage. The parts of flow_analyze_statement that use it know
where the returned operand needs to go. Unfortunately, this breaks dags
pretty hard, but that's because dags needs to learn about the fancy
assignment-type statements.

dec2e6249e [qfcc] Increase flow operand count to 5
MOVEP instructions have up to 5 operands: 2 pointers, the count, and 0-2
referenced variables (when known).

6ec92fb83b [qfcc] Point pointer tempop to the operand
It turns out I need the operand itself, not just the tempop.

0de011d0bf [qfcc] Add some disabled additional statement info
It's a bit cluttered for normal debugging, but I haven't decided how to
make it optional just yet.

0cbe438ac1 [util] Make va slight robust against chained use
va now cycles through a set of four dstrings rather than using just the
one. This allows for some simple chaining of va usage.

c5cbe83f71 [qfcc] Initialize statement numbers to -1
This is to indicate the statement has not yet been flow analyzed.

d02a01c282 [qfcc] Make tempop pointer strings more informative
Now that the address of a tempop can be taken, their op strings need to
be visible.

c5400c4581 [qfcc] Make anonstruct test robust against pointer math
I noticed that pointer math is currently incorrect in qfcc, but it would
be nice for fixing it to not break anonstruct since it is testing
something else.

0d784d9ef4 [qfcc] Rework address expr calculation
This removes a bogus lea from the instruction stream (and there can be
many such).

9cb3ee01d6 [qfcc] Add pointer value check
Extraction is a little more complicated, though, so undecided on that.

c3f04384d5 [qfcc] Make a general integral value extractor
All too often I just want the value.

888192a9ea [qfcc] Resurrect ex_def expression type
It turns out to be useful still as using symbol expressions isn't always
appropriate and the workarounds were getting nasty.

8e6baf1bde [qfcc] Fix assigning to entity fields
At least for basic types. Compound types need testing.

1d10136f2e [qfcc] Treat all dereferences and indirect
Why I had a const pointer test on there is beyond me.

69924fe717 [qfcc] Return correct value for is_const_ptr
It really helps if the logic is not inverted.

db06300ddd [qfcc] Make print_operand usable from gdb
It not emitting a \n made life difficult, especially whenever gdb
decided to make access to printf or puts awkward.

b544a052bf [gamecode] Bail if PR_SearchDefs is given 0 defs
Fixes the hang when searching for a field in progs that don't have any.

c8e45c6cfc [qfcc] Use operand_address in expr_deref
This fixes the technically correct but horrible mess of temps and
addressing when dealing with ivars, and the resulting uninitialized
temps due to the non-constant pointers (do need statement level constant
folding, though).

b58deb5680 [qfcc] Rewrite operand_address to be much simpler
It now creates a pointer value and returns that rather than generating
an address statement.

0fe3fda44d [qfcc] Fix protocol adorned id as message receiver
This took a bit as type_id has no class data, only protocols attached to
the type_obj_object instance, and then protocol lists can get deep.

fb33a7f2a7 [qfcc] Remove "impossible" code
It is not possible to adorn Class with protocols, so no need to check
for them when checking if a type is a class.

99f89840f9 [gamecode] Show containing def and relative offset
No more guessing when accessing structure field members. Next is ivars,
I guess.

3d62a7f253 [gamecode] Use fuzzy bsearch to find defs by address
The idea is to find th def that contains the address. Had to write my
own bsearch (well... lifted from wikipedia) because libc's is exact. The
defs are assumed to be sorted (which qfcc now ensures when it writes
progs and sym files).

327d692992 [qfcc] Correct order of @zero fields
This is part of what messed up float_val in the encoding for @params.
The other part is something in the linker type encoding merge code: it
may be too aggressive. It's also what messed up the size of @params.

fea6381574 [gamecode] Rework debug type handling a little
Type encodings are used whenever they are available. For now, if they
are not, then everything is treated as void (which prints <void>, not
very useful). Most return statements and references to .return are now
very readable (excluding structs), and only params going through "..."
are a messy union.

877ad35a82 [qwaq] Rework the hierarchy again
It doesn't work right now because View unconditionally sends refresh to
its textContext, but textContext can be a draw buffer which does not
respond to refresh. Still, these changes (notably the assignment chain
in qwaq-group.r really pushed qfcc).

72f4b8ccb5 [qfcc] Give address operands a good expression
That is, those created by operand_address. The dag code needs the
expression that is attached to the statement to have the correct
expression type in order to do the right thing with the operands and
aliasing, especially when generating temps. This fixes assignchain when
optimizing (all tests pass again).
