Adapting R code for different traps
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

Sound not working properly on Xen Dom0, but works on native

[PATCH nbdkit] tests: Cancel trap in cleanup function to avoid recursive traps.
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

Is trapping allowed when an add with nsw flag overflows?
...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 speculable. This means that the trap won't happen until the result is e.g. stored to memory. A bit like poison values in hardware. Something is still unclear to me: while, according to the examples in LangRef, a volatile store has undefined behavior when a...

[LLVMdev] Overflow trap
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

[PATCH 2/2 V2] drm/nv50: Improve PGRAPH interrupt handling.
This makes nouveau recognise and report more kinds of PGRAPH errors, as well as prevent GPU lockups resulting from some of them. Lots of guesswork was involved and some part of this is probably incorrect. Some potential-lockuop situations are handled by just resetting a whole PGRAPH subunit, which doesn't sound like a "proper" solution, but seems to work just fine... for now.
