Hi, Looking at the documents, it looks like all instructions, e.g. ADD, SUB work only on labels/registers and constants. e.g. %1 = add nsw i32 %value, 291 The only instructions that can work on the values on the stack or on the heap are LOAD and STORE. So the following is not possible: %local = alloca i32, align 4 %1 = add nsw i32* %local, 291 Is the above correct? Kind Regards James

Vhost log dirty pages directly to a userspace bitmap through GUP and kmap_atomic() since kernel doesn't have a set_bit_to_user() helper. This will cause issues for the arch that has virtually tagged caches. The way to fix is to keep using userspace virtual address. Fortunately, futex has a cmpxchg to userspace memory helper futex_atomic_cmpxchg_inatomic(). So switch to use it to exchange the

Hi R folks, I'd like to announce several new R users groups here in SF, LA, NYC, and Ottawa - as well as their next scheduled event. The goal of these user groups, besides gently explaining 'drop=TRUE' to the uninitiated, is to exchange knowledge, promote best practices, and spur the adoption of R for innovative applications. If I've missed any groups here, please feel to add on
