    Any chance to change this to asmjit in x64dbg? It seems to be using XEDParse which has issues.

    I can’t get it to assemble “movss dword ptr ss:[rsp+0x18], xmm2”

    int 10

    debugger shows
    CD 10 00 00

    where it is supposed to show:
    0A 00 00 00

    For xdbg plugin, it is better not to call IsDialogMessage, because it will modify the flow of the system message processing call, causing some unpredictable consequences. For example, for Chinese character set, raedit supports gbk encoding, but after the message processed by IsDialogMessage, the encoding received by WM_CHAR in the raedit message loop will be changed to unicode encoding. I spent a lot of time debugging to understand why it kept messing up after setting the font. Finally I commented out the following two lines and found that everything worked.
    //if(IsDialogMessage(hWnd, lpMsg))
    // return TRUE.

    • I’m not using Chinese, so I never experienced this problem. `IsDialogMessage` is used for other things, too, such as navigation with the tab key. There must be a more correct fix for that. If you find a better fix, let me know and I’ll consider including it in the plugin.
