...il loop when the number of elements processed is not a multiple of the vector length. For this use case, the tail predicate pragma could be good user experience improvement, as it would for example allow this more compact form without any predicated intrinsics: #pragma tail_predicate do { VLD(..); // some vector load intrinsic VST(..); // some vector store intrinsic .. } while (N); which can then be transformed and predication made explicit through data dependencies like so: do { mask = vctp(N); // intrinsic that generates the mask of active lanes VLD(.., mas...

This probably isn't causing the hang, but it's bad practice in general, as it prevents the engines from running in parallel.

G92's seem to require some additional bit of initialization before the BSP engine can work. It feels like clocks are not set up for the underlying VLD engine, which means that all commands submitted to the xtensa chip end up hanging. VP seems to work fine though. This still allows people to force-enable the bsp engine if they want to play around with it, but makes it harder for the card to hang by default. Signed-off-by: Ilia Mirkin <imirkin...

No, I am afraid not without computing alignment based on the scalar code. In order to limit vectorization to 16-byte aligned data we need to know that data is 16-byte aligned. The way we vectorize we won’t know that until after we have vectorized. As you have observed we will pass “4” to getMemoryOpCost in the loop vectorizer (as that is the only thing that can be inferred from a consecutive

Ok any quick workaround to limit vectorization to 16-byte aligned 128-bit data then? All the memory copying done by ExpandUnalignedStore/ExpandUnalignedLoad is just too expensive.

Hi, We are now about halfway between the 3.4 and 3.5 releases, and I would like to start preparing for a 3.4.1 release. Here is my proposed release schedule: Mar 26 - April 9: Identify and backport additional bug fixes to the 3.4 branch. April 9 - April 18: Testing Phase April 18: 3.4.1 Release How you can help: - If you have any bug fixes you think should be included to 3.4.1, send me an
