How to reuse my self function?
Dear all, I wrote a function test1 in test1.R. Right, I am writing another function test2 on test2.R and trying to use test1 function. How can I do? Is there any similar way like including test1.R in test2.R file? Thank You Very Much.

RE: A question on vmx loader in xen - how and when rombiosis loaded into memory
Thank you. I notice the system then jumps to F000:FFF0 to execute. But because VMX is turned on, switching to real-mode would incur problems? I don’t find any clue to turn on the vm86 mode as Readme in the tools/firmware directory puts.

Pairwise combination
...ents of the input vector. For example, the input vector is c(1,2,3,4). The output vector is c(1 and 2, 1 and 3, 1 and 4, 2 and 3, 2 and 4, 3 and 4). The representation here is generic. I can use a for loop to do it, but it gets slow when the number of elements of the input vector is large.

Will Xen support PCI add-on card for serial ports?
hi, It looks that Xen currently only support ISA serial port, which is onboard. Is there any plan to support the PCI serial port? Thanks, Neo -- I would remember that if researchers were not ambitious probably today we haven''t the technology we are using! _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com

Testing CFL alias analysis
Hi Geoff, Thank you so much for the effort! It's good to hear that cfl-aa didn't break anything. However, the fact that it doesn't quite affect code generation is also concerning. I'll definitely look into the issue.

[LLVMdev] There are compiling errors when converting bytecode to c by LLC
Hi Fei Jia, What revision are you using? I suggest you to try C backend with the most recent LLVM version, if possible. I recall I had some similar C backend breakages in July-August: structs definitions were lost somewhere. To my understanding, the correct result should look like this: /* Typedefs */ typed...
