[qwaq] Bring in qc gcd to use for debugger testing
...
It was even recent enough to compile first try.
2020-03-24 23:02:19 +09:00
298fcbbf70
[qfcc] Add ExitCode support to quake-pascal
...
gcd now passes :)
2020-03-20 12:59:25 +09:00

[qfcc] Resync qc and qp common symbols
...
Forgot I needed to remove PAS from pascal as well.
2020-03-20 12:59:25 +09:00

[qfcc] Add gcd.pas to the tests

[qfcc] Recover from syntax errors in abstract_decl
2020-03-19 11:01:26 +09:00
4c6e1b7fc4
[qfcc] Fix some uninitialized variable warnings
...
I really wish gcc would catch more issues when not optimizing.

[qfcc] Mark known source def live for movep
...
This fixes ivar-struct-return (and qwaq).
2020-03-18 00:02:36 +09:00
43ea34535e
[qfcc] Make ivar-struct-return fail
...
It turns out that assignments to struct fields are not counted as live
when the whole struct is later used via a pointer move.
2020-03-17 23:39:17 +09:00
22cd39c853
[qfcc] Mark ptr assignment offset as an operand
...
This fixes structptr. All current tests pass.
2020-03-17 23:05:57 +09:00
578bf9a16f
[qfcc] Set dag node value for movep
...
This fixes compilation of all tests. However, structptr still fails.
2020-03-17 22:54:27 +09:00
34c9ec51bb
[qfcc] Make opcode and statement type names available
2020-03-17 22:46:23 +09:00
77806f4b1b
[qfcc] Get dag code generation mostly working
...
There's an ICE in return-ivar, but assignchain passes let alone builds.
2020-03-17 22:35:36 +09:00
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)
2020-03-17 21:39:49 +09:00
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.
2020-03-17 21:30:16 +09:00
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).

[qfcc] Analyze tempop pointers in move/memset statements
2020-03-17 15:48:06 +09:00
6ec92fb83b
[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
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.
2020-03-17 15:23:24 +09:00
c5cbe83f71
[qfcc] Initialize statement numbers to -1
...
This is to indicate the statement has not yet been flow analyzed.
2020-03-17 15:05:58 +09:00
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.

[qfcc] Correctly implement pointer arithmetic
2020-03-17 13:39:22 +09:00
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.
2020-03-17 12:16:24 +09:00
0d784d9ef4
[qfcc] Rework address expr calculation
...
This removes a bogus lea from the instruction stream (and there can be
many such).
2020-03-17 12:13:09 +09:00

[qfcc] Improve robustness of do_op_integer
2020-03-17 12:12:06 +09:00
9cb3ee01d6
[qfcc] Add pointer value check
...
Extraction is a little more complicated, though, so undecided on that.
2020-03-17 11:19:12 +09:00
c3f04384d5
[qfcc] Make a general integral value extractor
...
All too often I just want the value.
2020-03-17 11:18:37 +09:00
80967e1471
[qfcc] Support def exprs in integral value extractors
2020-03-17 10:56:45 +09:00

[qfcc] Improve integral value extraction readability
2020-03-17 10:55:27 +09:00
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.
2020-03-17 01:42:46 +09:00
fd06cd2b00
[qfcc] Analyze assignment through const pointers
...
This fixes a false-positive uninitialized warning.
2020-03-17 01:40:35 +09:00
8e6baf1bde
[qfcc] Fix assigning to entity fields
...
At least for basic types. Compound types need testing.
2020-03-17 01:39:35 +09:00

[qfcc] Make is_indirect easier to read
2020-03-16 23:26:39 +09:00

[qfcc] Add is_entity type test helper
2020-03-16 21:07:31 +09:00

[qfcc] Catch attempts to emit a bad operand type
2020-03-16 20:31:21 +09:00
1d10136f2e
[qfcc] Treat all dereferences and indirect
...
Why I had a const pointer test on there is beyond me.
2020-03-16 20:24:22 +09:00
69924fe717
[qfcc] Return correct value for is_const_ptr
...
It really helps if the logic is not inverted.
2020-03-16 20:21:07 +09:00
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.
2020-03-16 20:20:07 +09:00
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).
2020-03-16 14:24:48 +09:00
b58deb5680
[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
a0c28a5ac5
[qfcc] Support pointers to temp operands
...
This is necessary for correctly taking the address of operands.
2020-03-16 14:24:47 +09:00

[qfcc] Improve accuracy of some more diagnostics
2020-03-16 10:42:18 +09:00
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.
2020-03-16 10:42:18 +09:00
ea042cf87a
[qfcc] Split out the obj-qc specific expr code
2020-03-16 10:34:16 +09:00
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.

How do you have -1 def?

[qfcc] Ensure progs defs are sorted by address
2020-03-15 01:32:38 +09:00

[qfcc] Set local def size in debug sym file
...
It was getting random garbage. Not good for debuggers.
2020-03-14 22:08:27 +09:00
20fd5eb80c
[qfcc] Show def size when dumping defs
2020-03-14 22:07:36 +09:00
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.
