[LLVMdev] JIT on Windows x64
..._bug.cgi?id=3739. I checked out the revision the patch was created for (66183) and applied it but the assembler generated seems to fail whenever it reaches a movaps insctruction. eg. movaps xmmword ptr [rsp+20h],xmm8 movaps xmmword ptr [rsp+30h],xmm7 movaps xmmword ptr [rsp+40h],xmm6 Would this have something to do with the stack alignment? I am wondering if anybody else has had any success using that patch to get Windows x64 JIT to work correctly. Or if my problem may be unrelated. Any suggestions would be useful.

Comboot Menu
Since lot of people want this thing, I will try to take a stab at it. For now, I will hard code the menu in the code, and then somebody else can remove that restriction. May be we can add some kind of keyword to the config file which syslinux ignores and the comboot menu does something with it. I have one question about comboot: If I write a DOS program using C (compiled using watcom -3 -mt -osx

Enhanced MDISKCHK.COM and MEMDISK patches
Good day to all, Gert Hulselmans requested a feature for MDISKCHK.COM that would function roughly like GETARGS.COM[1] by Murali Krishnan Ganapathy: DOS SET command output for MEMDISK kernel arguments passed by previous boot-loaders. He also needed to support the case for MEMDISK-in-a-MEMDISK type situations, where all MEMDISK kernel arguments could be gathered together and output as a list

Hmm, I'm not able to get those .ll files to compile if I disable SSE and I end up with SSE instructions(including sqrtpd) if I don't disable it.
