If it doesn't properly, we should fix that. Isn't this only worth when the SIMD instructions can be conditionalised per lane? I believe AVX512 and SVE have such abilities, but not NEON or SSE. Does SystemZ support conditionalisation in SIMD? cheers, --renato

Hi, Looking at bugzilla PR11087, I'd like to conditionalise a transformation in ARMIselLowering.cpp based on whether we're compiling for codesize or performance. -Os doesn't actually exist for llc, and I can't see an obvious place where that condition would be set. Where do we specify if we're optimizing for codesize or performance?...

Hi, it seems to be generally a bad idea to enable vectorization of conditional stores on SystemZ, because it will cost extra instructions both to 1. extract compare result element 2. Do a test-under-mask instruction on that element 3. conditional branch past the store block. Ideally, I would like to adjust the cost for the vector compare. I am not sure if this is feasable since I would need

...nt because it needs to allocate for each node in the tree). One difference is that filter here will match everything if there are no filter terms, so you can just always apply it: query = Xapian::Query(OP_FILTER, query, filter); The notmuch way will match nothing for that case so you need to conditionalise applying the filter (assuming you still want to match something when there are no filter terms). > With a set of integers I have (after sortable_serialise), would the > best way be to OP_OR a bunch of OP_VALUE_RANGE queries together? > > So, perhaps something like: > > Query(O...

I probably should've used boolean terms in addition to numeric values when indexing, but currently I have a set of numeric values[1] and trying to avoid having to reindex ~250GB DBs (and asking numerous users to do the same). Say I have a bunch of values which I want to filter a query against. If I had boolean terms, it could just OP_OR against the whole set. IOW, this is what notmuch does

As before several of the patches are not to be applied because they can be done better using infrastructure from Julien''s "Allow Xen to boot with a raw Device Tree" patch. They are included for completeness. With

Proposal for extending the Loop Vectorizer to handle Outer Loops ================================================================ Goal: ----- We propose to extend the innermost Loop Vectorizer to also handle outerloops (cf.[1]). Our aim is to best leverage the efforts already invested in the existing innermost Loop Vectorizer rather than introduce a separate pass dedicated to outerloop
