Hi, It looks like your patch introduced the new failures shown below. Please investigate and fix them before resubmitting your patch. If they are not new, fixing them anyway would help a lot. Otherwise please ask for the known failures list to be updated. The tests also ran into some preexisting test failures. If you know how to fix them that would be helpful.

[PATCH vkd3d 2/3] vkd3d-shader: Introduce a compile option to use Unknown format for typed UAV reads.

[PATCH v2] ntdll/signalx86_64: Add CFI for __wine_syscall_dispatcher
by Keno Fischer July 29, 2022

July 29, 2022

In a debugger that is capable of loading both PE and ELF libraries (e.g. the wine-enhanced GDB version at [1]), this unwind information will allow proper unwind across the __wine_syscall_dispatcher. The CFI itself is relatively straightforward, though the implementation looks a little complex, because support for proper CFI encoding is somewhat limitied in the GNU toolchain. Essentially, as registers are stored in the rcx buffer in this function, we switch their cfi description to point at that rcx buffer, so the registers may be freely used thereafter without affecting the unwind. Eventually the rcx buffer is tracked in rbp instead at which point we pivot the CFI information as well and keep it there for most of the rest of the function.

[PATCH] ntdll/signalx86_64: Add CFI for __wine_syscall_dispatcher
by Keno Fischer July 29, 2022

July 29, 2022

In a debugger that is capable of loading both PE and ELF libraries (e.g. the wine-enhanced GDB version at [1]), this unwind information will allow proper unwind across the __wine_syscall_dispatcher. The CFI itself is relatively straightforward, though the implementation looks a little complex, because support for proper CFI encoding is somewhat limitied in the GNU toolchain. Essentially, as registers are stored in the rcx buffer in this function, we switch their cfi description to point at that rcx buffer, so the registers may be freely used thereafter without affecting the unwind. Eventually the rcx buffer is tracked in rbp instead at which point we pivot the CFI information as well and keep it there for most of the rest of the function.
