[PATCH v4 0/5] MR786: vkd3d-shader/hlsl: Loop unrolling, part 1.
by Victor Chiletto (＠vitorhnn) 12 Apr '24

12 Apr '24

This is a simplified version of !748 that doesn't handle conditional jumps. I'll submit a cleaned up version of that after this. -- v4: vkd3d-shader/hlsl: Implement loop unrolling. vkd3d-shader/hlsl: Parse loop and unroll loop attributes. vkd3d-shader/hlsl: Pull evaluate_static_expression_as_uint upwards. https://gitlab.winehq.org/wine/vkd3d/-/merge_requests/786

[PATCH 0/6] MR748: vkd3d-shader/hlsl: Implement loop unrolling.
by Victor Chiletto (＠vitorhnn) 12 Apr '24

The general idea is: * Run copy prop initially, save the copy prop state. * Unroll one iteration, substitute all jumps by stores to synthetic control vars, move all instructions after the jumps to checks to those control vars. * Run copy prop on the iteration, using the previous iteration's or the root's state as the parent state. * Probe the copy prop state to check if the "loop_broken" control variable was set, stop unrolling if it true, otherwise continue. Some stuff I'm less sure about and would love comments on: * The way I deferred bounds checking. * Splitting the iter block from the body. This was needed because otherwise copy prop marks variable that are changed in iter blocks (e.g "i++") as invalidated and does not propagate them to subsequent iterations. * Messing around with copy prop internals. I attempted two other similar solutions that were less invasive: running copy prop on the entire block after each unroll and running copy prop once, after unrolling to `max_iterations`, both were too slow to be viable. -- https://gitlab.winehq.org/wine/vkd3d/-/merge_requests/748

[PATCH 0/5] MR5493: Extend minidump support in winedump.
by eric pouech (＠epo) 12 Apr '24

12 Apr '24

Improve minidump dumping in Wine dump: - support several -j options to only print relevant part of the file - support a bunch of new streams (memory list, token, thread names...) - several other cleanups and homogeinization of output -- https://gitlab.winehq.org/wine/wine/-/merge_requests/5493

[PATCH v11 0/1] MR364: kernel32/tests: Test module refcounting with forwarded exports.
by Jinoh Kang (＠iamahuman) 12 Apr '24

12 Apr '24

Test module references created by resolving forwarded exports. The following diagram (best viewed in light mode due to fixed colors) explains what happens in bug #52094 under the hood: ```mermaid graph TB subgraph state_00["Initial"] direction LR s00_ida[ida64.dll] ~~~ s00_idapy[idapython64.dll] -. "(import)" .-> s00_py3[python3.dll] -. "(forwards to)" .-> s00_py311[python311.dll] end state_00 -.

"<del>dynamic ref (deleted)</del>" .-> s03_py311 s03_idapy -- "static forwarded ref" --> s03_py311 end ``` On Windows, the static forwarded ref keeps `python311.dll` from being unloaded; however, Wine is missing this behavior, causing it to be unloaded and segfault immediately (since further initialization happens just after step 3 FreeLibrary). The tests aim to reproduce this condition. -- v11: kernel32/tests: Test module refcounting with forwarded exports. https://gitlab.winehq.org/wine/wine/-/merge_requests/364
