4de2c6b30e [qfcc] Move alias expr inside call block expression 
This fixes the trampled return value when the first expression aliases
the return result.

98eac2afbc [qfcc] Hide dependency generation commands 2020-03-26 20:16:32 +09:00
Bill Currie
15d4186fff [qfcc] Show line numbers in block sub expressions 
Seems more useful than expression index.
 2020-03-26 20:15:50 +09:00
Bill Currie
5fd63b95db [qfcc] Add a new failing test 
The struct alias is somehow blocking the detection of the call so the
return value gets corrupted.

1f8cc7186c [qfcc] Hide "function" type behind an @ 
I'm not sure it's all that useful and thus it clutters the namespace.

4cef9792f4 [util] Make hash-tables semi-thread-safe 
They take a pointer to a free-list used for hashlinks so the hashlink
pools can be per-thread. However, hash tables that are not updated are
always thread-safe, so this affects only updates. progs_t has been set
up such that it is easy for multiple progs within one thread can share
hashlinks.

9bfd14b687 [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
Bill Currie
298fcbbf70 [qfcc] Add ExitCode support to quake-pascal 
gcd now passes :)
 2020-03-20 12:59:25 +09:00
Bill Currie
ed03eeb8d2 [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
Bill Currie
f64038b872 [qfcc] Add gcd.pas to the tests 2020-03-20 12:59:25 +09:00

7447854d7c [qfcc] Recover from syntax errors in abstract_decl 2020-03-19 11:01:26 +09:00
Bill Currie
4c6e1b7fc4 [qfcc] Fix some uninitialized variable warnings 
I really wish gcc would catch more issues when not optimizing.
 2020-03-18 01:51:52 +09:00

0293d335d0 [qfcc] Mark known source def live for movep 
This fixes ivar-struct-return (and qwaq).
 2020-03-18 00:02:36 +09:00
Bill Currie
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
Bill Currie
22cd39c853 [qfcc] Mark ptr assignment offset as an operand 
This fixes structptr. All current tests pass.
 2020-03-17 23:05:57 +09:00
Bill Currie
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
Bill Currie
34c9ec51bb [qfcc] Make opcode and statement type names available 2020-03-17 22:46:23 +09:00
Bill Currie
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
Bill Currie
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
Bill Currie
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
Bill Currie
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).

fa2cbc72d8 [qfcc] Analyze tempop pointers in move/memset statements 2020-03-17 15:48:06 +09:00
Bill Currie
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
Bill Currie
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
Bill Currie
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
Bill Currie
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.
 2020-03-17 15:05:58 +09:00
Bill Currie
441e7b99bc [qfcc] Correctly implement pointer arithmetic 2020-03-17 13:39:22 +09:00
Bill Currie
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
Bill Currie
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
Bill Currie
0d751dcdc5 [qfcc] Improve robustness of do_op_integer 2020-03-17 12:12:06 +09:00
Bill Currie
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
Bill Currie
c3f04384d5 [qfcc] Make a general integral value extractor 
All too often I just want the value.
 2020-03-17 11:18:37 +09:00
Bill Currie
80967e1471 [qfcc] Support def exprs in integral value extractors 2020-03-17 10:56:45 +09:00
Bill Currie
e4a403bbb3 [qfcc] Improve integral value extraction readability 2020-03-17 10:55:27 +09:00
Bill Currie
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
Bill Currie
fd06cd2b00 [qfcc] Analyze assignment through const pointers 
This fixes a false-positive uninitialized warning.
 2020-03-17 01:40:35 +09:00
Bill Currie
8e6baf1bde [qfcc] Fix assigning to entity fields 
At least for basic types. Compound types need testing.
 2020-03-17 01:39:35 +09:00
Bill Currie
f9face0cef [qfcc] Make is_indirect easier to read 2020-03-16 23:26:39 +09:00
Bill Currie
5c0c056e2c [qfcc] Add is_entity type test helper 2020-03-16 21:07:31 +09:00
Bill Currie
ede7dd6d7e [qfcc] Catch attempts to emit a bad operand type 2020-03-16 20:31:21 +09:00
Bill Currie
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
Bill Currie
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
Bill Currie
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
Bill Currie
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
Bill Currie
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
Bill Currie
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
Bill Currie
2f07d9a310 [qfcc] Improve accuracy of some more diagnostics 2020-03-16 10:42:18 +09:00
Bill Currie
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
Bill Currie
ea042cf87a [qfcc] Split out the obj-qc specific expr code 2020-03-16 10:34:16 +09:00
Bill Currie
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.
