Hi, I''m running Xen 4.2.0 with Linux kernel 3.7.0 and I''m seeing a flood of these messages in xen dmesg: (XEN) traps.c:3156: GPF (0060): ffff82c480159247 -> ffff82c4802170e4 (XEN) traps.c:3156: GPF (0060): ffff82c480159247 -> ffff82c4802170e4 (XEN) traps.c:3156: GPF (0060): ffff82c480159247 -> ffff82c4802170e4 (XEN) traps.c:3156: GPF (0060): ffff82c480159247 ->

On x86_64, the trap instruction is executed, and then you stop, so the PC is left after the stop. On arm64, when execution halts the pc is still pointing at the trap instruction. > > I don't think lldb should be in the business of telling

Hi all, My code: > temp<-outer(release.days,collection.days,'-') > temp<-ifelse(temp>=0,NA,temp) > release.diff<-apply(temp,2,max,na.rm=TRUE) works for one trap and does what I want. That is, it determines the time difference between the collection date of a trap and date of parasitoid release immediately before it, excluding releases that occurred on the same day

Hi, I''m doing some testing on Ubuntu 12.04 Alpha. All sounds comes out as static on the Dom0 system. (I can PCI passthrough the audio card to a DomU and that works). Native sound works fine.

In these test functions, when a test fails, the bash ‘trap’ command causes the cleanup function to be called. However bash does not annul or cancel the traps when cleanup is called, so at the end of the cleanup function when ‘exit’ is called, cleanup is called recursively. Avoid this by cancelling the traps at the top of the cleanup function. Also an extra debugging message is emitted here

[This mail could be an answer to the other responses as well, as they basically are the same.] Ah, I think I understand now what poison is for. Adds are defined to not have side-effects, so the dependence rule is needed so the optimizer is allowed to exploit undefined behavior. Is this correct? I forgot to mention in my original mail that our trapping arithmetic operations are fully

Several instruction set architectures include arithmetic operations that can trap on overflow, or support this feature with a separate trap-on-overflow-flag instruction (such as the x86 INTO instruction). I am adding a back-end to the Open Dylan compiler to generate LLVM IR. The original back-end, which generates x86 machine code, makes use of the INTO instruction, and the runtime turns the
