Fastcall calling convention
by Damjan Jovanovic 23 Mar '10

23 Mar '10

Hi Wine doesn't seem to support the fastcall calling convention: include/winternl.h: /* These are implemented as __fastcall, so we can't let Winelib apps link with them */ dlls/hal/hal.c: #ifdef __i386__ #define DEFINE_FASTCALL1_ENTRYPOINT( name ) \ __ASM_STDCALL_FUNC( name, 4, \ "popl %eax\n\t" \ "pushl %ecx\n\t" \ "pushl %eax\n\t" \ "jmp " __ASM_NAME("__regs_") #name __ASM_STDCALL(4)) GCC seems to support fastcall from version 3.4: http://www.ohse.de/uwe/articles/gcc-attributes.html Should we support it? Its absence makes kernel driver code a lot uglier (eg. irp->Tail.Overlay.s.u2.CurrentStackLocation instead of IoGetCurrentIrpStackLocation()). We also can't declare fastcall functions in header files, so some functions that are actually implemented are missing from header files and thus unusable from inside Wine. Thank you Damjan Jovanovic

If you mean here that native oleaut32 uses this call, a general FIXME is enough. If you really don't want to survive from such call you don't need this stub at all.

Re: 4/4 wined3d: move color keyed blitting in its own function

When you create a "new" function, try to make it at least somewhat sane and consistent, rather than just cutting and pasting something together.

[PATCH] dlls/msxml3: Using strlenW instead of SysStringLen to check node name length
by Eric Lanz 22 Mar '10

22 Mar '10

Hello, Decided to keep it simple for my first patch. SysStringLen was returning 0 for bstrs from our updater application which caused the domdoc_createNode function to exit early even though the bstr actually contained a valid name. It seems that other functions in this file use strlenW for this purpose which seems to always return the correct length. Eric

Re : shell32: Add IShellFolderView:: GetSelectedObjects implementation for IShellView.
by Juan Lang 22 Mar '10

22 Mar '10

Hi Nikolay, I know this one's already been comitted, but I have a small complaint about a comment: + /* it's documented that caller shouldn't PIDLs, only array itself */ I think you're missing a verb there. A caller shouldn't do what to PIDLs, exactly? Perhaps it should be obvious to me, but I couldn't guess by looking at it. Thanks, --Juan

Warnings on ignored returned values
by Octavian Voicu 22 Mar '10

22 Mar '10

Hello, I'm trying to compile wine with --enable-maintainer-mode and I get lots of errors like `ignoring return value of ‘xxx’, declared with attribute warn_unused_result'. I would like to submit a few patches to fix them. I noticed there's a page on the wiki for this: http://wiki.winehq.org/IgnoredReturnValues On the other hand, there are no indications on the policy of handling them. Sometimes we just don't care about the return value, but I haven't found a way to tell this to the compiler other than actually using the return value. In other cases, errors might be relevant. For example, for the code: if (newdir) chdir(newdir); would the following be an acceptable fix? if (newdir) if (chdir(newdir) == -1) /* ignore error */ ; Should I use WARNs to print the error, in cases where it might be relevant? Thanks, Octavian
