[qfcc] Mark ptr assignment offset as an operand
...
This fixes structptr. All current tests pass.

[qfcc] Set dag node value for movep
...
This fixes compilation of all tests. However, structptr still fails.

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

[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)

[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.

[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).

[qfcc] Point pointer tempop to the operand
...
It turns out I need the operand itself, not just the tempop.
2020-03-17 15:47:42 +09:00

[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.

[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.
2020-03-17 15:05:58 +09:00
c5cbe83f71
[qfcc] Initialize statement numbers to -1
...
This is to indicate the statement has not yet been flow analyzed.

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

[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.
2020-03-17 12:16:24 +09:00

[qfcc] Rework address expr calculation

This removes a bogus lea from the instruction stream (and there can be
many such).

Extraction is a little more complicated, though, so undecided on that.

[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.

[qfcc] Fix assigning to entity fields

At least for basic types. Compound types need testing.

[qfcc] Treat all dereferences and indirect

Why I had a const pointer test on there is beyond me.

[qfcc] Return correct value for is_const_ptr

It really helps if the logic is not inverted.

[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.

[gamecode] Bail if PR_SearchDefs is given 0 defs

[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).
2020-03-16 14:24:48 +09:00

[qfcc] Rewrite operand_address to be much simpler
...
It now creates a pointer value and returns that rather than generating
an address statement.
2020-03-16 14:24:47 +09:00

[qfcc] Support pointers to temp operands

[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.

[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.

No more guessing when accessing structure field members. Next is ivars,
I guess.

[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).

[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.
