[PATCH 0/4] MR9429: Avoid a few compiler warnings.
by Bernhard Übelacker Nov. 13, 2025

Nov. 13, 2025

Gitlab CI uses `--enable-werror` for its builds, but to improve backtraces with my recent address sanitizer experiments I am using these flags `-g -O1 -fno-omit-frame-pointer -mno-omit-leaf-frame-pointer -fno-optimize-sibling-calls -fno-inline-functions` with both, gcc at the unix side and llvm-mingw at the pe side. Therefore these warnings would turn into errors. This four patches are helping gcc at the unix side. Would these patches be acceptable? Should they be separate merge requests? <details> <summary>Details</summary> ``` ccache gcc -m64 -c -o tools/winebuild/utils.o .../wine/tools/winebuild/utils.c \ -Itools/winebuild -I.../wine/tools/winebuild -Iinclude \ -I.../wine/include -D__WINESRC__ -DWINE_UNIX_LIB -Wall -pipe \ -fcf-protection=none -fvisibility=hidden -fno-stack-protector -fno-strict-aliasing \ -Wdeclaration-after-statement -Wempty-body -Wignored-qualifiers -Winit-self -Wlogical-op \ -Wno-packed-not-aligned -Wpointer-arith -Wshift-overflow=2 -Wstrict-prototypes -Wtype-limits \ -Wunused-but-set-parameter -Wvla -Wwrite-strings -Wno-misleading-indentation -gdwarf-4 -Werror \ -g -O1 -fno-omit-frame-pointer -mno-omit-leaf-frame-pointer -fno-optimize-sibling-calls -fno-inline-functions .../wine/tools/winebuild/utils.c: In function 'find_tool': .../wine/tools/winebuild/utils.c:230:8: error: 'file' may be used uninitialized [-Werror=maybe-uninitialized] 230 | if (!file && cc_command.count) file = find_clang_tool( cc_command, name ); | ^ .../wine/tools/winebuild/utils.c:214:17: note: 'file' was declared here 214 | const char *file; | ^~~~ cc1: all warnings being treated as errors make: *** [Makefile:610992: tools/winebuild/utils.o] Error 1 ccache gcc -m64 -c -o dlls/ntdll/unix/file.o .../wine/dlls/ntdll/unix/file.c -Idlls/ntdll \ -I.../wine/dlls/ntdll -Iinclude \ -I.../wine/include -D__WINESRC__ -DLTC_NO_PROTOTYPES \ -DLTC_SOURCE -D_NTSYSTEM_ -D_ACRTIMP= -DWINBASEAPI= -DWINE_UNIX_LIB \ -I/usr/include/x86_64-linux-gnu -Wall -pipe -fcf-protection=none -fvisibility=hidden \ -fno-stack-protector -fno-strict-aliasing -Wdeclaration-after-statement -Wempty-body \ -Wignored-qualifiers -Winit-self -Wlogical-op -Wno-packed-not-aligned -Wpointer-arith \ -Wshift-overflow=2 -Wstrict-prototypes -Wtype-limits -Wunused-but-set-parameter -Wvla \ -Wwrite-strings -Wno-misleading-indentation -gdwarf-4 -Werror -fPIC -fasynchronous-unwind-tables \ -g -O1 -fno-omit-frame-pointer -mno-omit-leaf-frame-pointer -fno-optimize-sibling-calls -fno-inline-functions .../wine/dlls/ntdll/unix/file.c: In function 'NtReadFile': .../wine/dlls/ntdll/unix/file.c:5758:23: error: 'avail_mode' may be used uninitialized [-Werror=maybe-uninitialized] 5758 | if (total && avail_mode) | ~~~~~~^~~~~~~~~~~~~ .../wine/dlls/ntdll/unix/file.c:5755:18: note: 'avail_mode' was declared here 5755 | BOOL avail_mode; | ^~~~~~~~~~ cc1: all warnings being treated as errors make: *** [Makefile:318598: dlls/ntdll/unix/file.o] Error 1 ccache gcc -m64 -c -o dlls/sane.ds/unixlib.o .../wine/dlls/sane.ds/unixlib.c -Idlls/sane.ds \ -I.../wine/dlls/sane.ds -Iinclude \ -I.../wine/include -D__WINESRC__ -DWINE_UNIX_LIB -Wall -pipe \ -fcf-protection=none -fvisibility=hidden -fno-stack-protector -fno-strict-aliasing \ -Wdeclaration-after-statement -Wempty-body -Wignored-qualifiers -Winit-self -Wlogical-op \ -Wno-packed-not-aligned -Wpointer-arith -Wshift-overflow=2 -Wstrict-prototypes -Wtype-limits \ -Wunused-but-set-parameter -Wvla -Wwrite-strings -Wno-misleading-indentation -gdwarf-4 -Werror \ -fPIC -fasynchronous-unwind-tables -g -O1 -fno-omit-frame-pointer -mno-omit-leaf-frame-pointer -fno-optimize-sibling-calls -fno-inline-functions .../wine/dlls/sane.ds/unixlib.c: In function 'read_data': .../wine/dlls/sane.ds/unixlib.c:332:8: error: 'status' may be used uninitialized [-Werror=maybe-uninitialized] 332 | if (status == SANE_STATUS_EOF) return TWCC_SUCCESS; | ^ .../wine/dlls/sane.ds/unixlib.c:321:17: note: 'status' was declared here 321 | SANE_Status status; | ^~~~~~ cc1: all warnings being treated as errors make: *** [Makefile:366624: dlls/sane.ds/unixlib.o] Error 1 ccache gcc -m64 -c -o server/directory.o .../wine/server/directory.c -Iserver \ -I.../wine/server -Iinclude \ -I.../wine/include -D__WINESRC__ -DWINE_UNIX_LIB -Wall -pipe \ -fcf-protection=none -fvisibility=hidden -fno-stack-protector -fno-strict-aliasing \ -Wdeclaration-after-statement -Wempty-body -Wignored-qualifiers -Winit-self -Wlogical-op \ -Wno-packed-not-aligned -Wpointer-arith -Wshift-overflow=2 -Wstrict-prototypes -Wtype-limits \ -Wunused-but-set-parameter -Wvla -Wwrite-strings -Wno-misleading-indentation -gdwarf-4 -Werror \ -g -O1 -fno-omit-frame-pointer -mno-omit-leaf-frame-pointer -fno-optimize-sibling-calls -fno-inline-functions .../wine/server/directory.c: In function 'create_session': .../wine/server/directory.c:327:44: error: 'snprintf' output may be truncated before the last format character [-Werror=format-truncation=] 327 | snprintf( id_strA, sizeof(id_strA), "%u", id ); | ^ .../wine/server/directory.c:327:5: note: 'snprintf' output between 2 and 11 bytes into a destination of size 10 327 | snprintf( id_strA, sizeof(id_strA), "%u", id ); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ cc1: all warnings being treated as errors make: *** [Makefile:607457: server/directory.o] Error 1 ``` </details> -- https://gitlab.winehq.org/wine/wine/-/merge_requests/9429

[PATCH v3 0/1] MR9449: winex11.drv: Fix xinerama_get_fullscreen_monitors() not working correctly with...
by Zhiyi Zhang (＠zhiyi) Nov. 13, 2025

Nov. 13, 2025

winex11.drv: Fix xinerama_get_fullscreen_monitors() not working correctly with non-fullscreen rects. xinerama_get_fullscreen_monitors() was supposed to be called with fullscreen rects. Thus, we could assume the monitor indices are all zero when there is only one monitor as an optimization. However, after baf65867, xinerama_get_fullscreen_monitors() can be called with non-fullscreen rects. So we need to remove the optimization so that it works correctly for non-fullscreen rects as well. Fix the Guild Wars 2 game window having an offset in fullscreen mode. -- v3: winex11.drv: Fix xinerama_get_fullscreen_monitors() not working correctly with non-fullscreen rects. https://gitlab.winehq.org/wine/wine/-/merge_requests/9449

[PATCH 0/5] MR9448: opengl32: Match native GL_VENDOR and GL_RENDERER strings.
by Rémi Bernon Nov. 13, 2025

Nov. 13, 2025

As much as possible at least. Some applications expect the GL_RENDERER strings to be shorter than 64 chars, as they copy it to some local buffer. They also seem to crash after GL_VENDOR call, possibly expecting native names too, so lets try to match both. The GPU name table is taken from wined3d, and it should then be possible to get rid of the names there and always use the descriptions from the registry / GL_RENDERER strings instead. The vendor names differ between OpenGL and the registry on Windows, GL_VENDOR names are taken from https://feedback.wildfiregames.com/report/opengl/feature/GL_VENDOR.

[PATCH 0/1] MR9445: opencl: Silence warnings on macOS for functions deprecated by OpenCL 1.2.
by Brendan Shanks (＠bshanks) Nov. 12, 2025

Nov. 12, 2025

There are 6 functions that were deprecated in OpenCL 1.2 and are marked deprecated in the macOS headers (without any way to disable the `deprecated` attribute other than `#pragma diagnostic ignored`). Fixes these warnings: ``` ../dlls/opencl/unix_thunks.c:38:25: warning: 'clCreateImage2D' is deprecated: first deprecated in macOS 10.8 [-Wdeprecated-declarations] 38 | *params->__retval = clCreateImage2D( params->context, params->flags, params->image_format, params->image_width, params->image_height, params->image_row_pitch, params->host_ptr, params->errcode_ret ); | ^ /Applications/Xcode26.1.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks/OpenCL.framework/Headers/cl.h:1170:1: note: 'clCreateImage2D' has been explicitly marked deprecated here 1170 | clCreateImage2D(cl_context /* context */, | ^ ../dlls/opencl/unix_thunks.c:46:25: warning: 'clCreateImage3D' is deprecated: first deprecated in macOS 10.8 [-Wdeprecated-declarations] 46 | *params->__retval = clCreateImage3D( params->context, params->flags, params->image_format, params->image_width, params->image_height, params->image_depth, params->image_row_pitch, params->image_slice_pitch, params->host_ptr, params->errcode_ret ); | ^ /Applications/Xcode26.1.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks/OpenCL.framework/Headers/cl.h:1180:1: note: 'clCreateImage3D' has been explicitly marked deprecated here 1180 | clCreateImage3D(cl_context /* context */, | ^ ../dlls/opencl/unix_thunks.c:124:12: warning: 'clEnqueueBarrier' is deprecated: first deprecated in macOS 10.8 [-Wdeprecated-declarations] 124 | return clEnqueueBarrier( params->command_queue ); | ^ /Applications/Xcode26.1.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks/OpenCL.framework/Headers/cl.h:1201:1: note: 'clEnqueueBarrier' has been explicitly marked deprecated here 1201 | clEnqueueBarrier(cl_command_queue /* command_queue */) CL_EXT_SUFFIX__VERSION_1_1_DEPRECATED; | ^ ../dlls/opencl/unix_thunks.c:203:12: warning: 'clEnqueueMarker' is deprecated: first deprecated in macOS 10.8 [-Wdeprecated-declarations] 203 | return clEnqueueMarker( params->command_queue, params->event ); | ^ /Applications/Xcode26.1.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks/OpenCL.framework/Headers/cl.h:1192:1: note: 'clEnqueueMarker' has been explicitly marked deprecated here 1192 | clEnqueueMarker(cl_command_queue /* command_queue */, | ^ ../dlls/opencl/unix_thunks.c:266:12: warning: 'clEnqueueWaitForEvents' is deprecated: first deprecated in macOS 10.8 [-Wdeprecated-declarations] 266 | return clEnqueueWaitForEvents( params->command_queue, params->num_events, params->event_list ); | ^ /Applications/Xcode26.1.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks/OpenCL.framework/Headers/cl.h:1196:1: note: 'clEnqueueWaitForEvents' has been explicitly marked deprecated here 1196 | clEnqueueWaitForEvents(cl_command_queue /* command_queue */, | ^ ../dlls/opencl/unix_thunks.c:551:12: warning: 'clUnloadCompiler' is deprecated: first deprecated in macOS 10.8 [-Wdeprecated-declarations] 551 | return clUnloadCompiler(); | ^ /Applications/Xcode26.1.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks/OpenCL.framework/Headers/cl.h:1204:1: note: 'clUnloadCompiler' has been explicitly marked deprecated here 1204 | clUnloadCompiler(void) CL_EXT_SUFFIX__VERSION_1_1_DEPRECATED; | ^ 6 warnings generated. ``` -- https://gitlab.winehq.org/wine/wine/-/merge_requests/9445

[PATCH v2 0/5] MR9437: win32u, vulkan-1: Test D3DKMT fence signal / wait / Vulkan interop.
by Rémi Bernon Nov. 12, 2025

Nov. 12, 2025

This adds D3DKMT sync object monitored fence tests, showing that the fences can be rewound when requested explicitly. Also adds some interop tests between D3D11 / D3D12 / Vulkan. The vulkan-1 tests show that timeline semaphores are rewindable on Windows even when not shared (at least with NVIDIA GPU), which is forbidden by spec but useful if not required for D3D12 fence interop. -- v2: vulkan-1/tests: Add timeline semaphore tests. win32u/tests: Add external semaphore / fences tests. win32u/tests: Test NtGdiDdDDI(Signal|WaitFor)SynchronizationObjectFromCpu. win32u: Stub NtGdiDdDDI(Signal|WaitFor)SynchronizationObjectFromCpu. winevulkan: Force copy some missing semaphore / fence structs. https://gitlab.winehq.org/wine/wine/-/merge_requests/9437
