[LLVMdev] Packed instructions generaetd by LoopVectorize?
...ugh it should not be required I tried doing the same to the input arrays of my dot product example but it still doesn't generate packed float or double instructions. Is the loop vectorizer supposed to generate packed float and double instructions? Is this a bug, or am I doing something wrong?

Help in understanding physreg LiveVariables

[LLVMdev] Use list preservation when using Instruction::clone
...copy over the function body. Now, consider a phi node p in F, and an instruction I in F which uses p. The problem is, the cloned phi node p' in G still lists I as a user. Is this intended behavior? And if so, is there a way I can remove these Use edges in my cloned function? Thanks, Tyler

[LLVMdev] Splitting basic block results in unknown instruction type assertion
Hello, I would like to see if this issue is a result of a misunderstanding on my part before I file a bug. I am using LLVM 3.4, built from the source tarballs. My system's uname is "Darwin tyler-air 12.5.0 Darwin Kernel Version 12.5.0: Sun Sep 29 13:33:47 PDT 2013; root:xnu-2050.48.12~1/RELEASE_X86_64 x86_64". All I'm trying to do is add a runtime check after all call instructions. To do this I would (eventually) like to add a branch to an "error" block that abo...

[LLVMdev] Generate scalar SSE instructions instead of packed instructions
Thanks for the reply, they were very helpful. Is it enough to prevent BBVectorize from packing together double precision instructions? If a non-clang frontend is used, such as ISPC, is it possible that the IR may contain packed double instruction?

dyn.load in linux: missing libraries?

Rebooting to hard drive from DOS floppy
...ut it does not support the localboot option like pxelinux and isolinux do. Basically, I want to boot DOS from a floppy, run some DOS stuff, then reboot to the hard drive while leaving the floppy disk in the drive. Loadlin would be perfect if it supported OSes other than Linux. Suggestions? TIA! Tyler
