[LLVMdev] [llvm-commits] Vectors of Pointers and Vector-GEP
...at does the non-unit stride case look like? I have two ways I think
about a gather/scatter or non-unit stride access.
1. Vector-of-indices
This looks something like:
V1 <- Base + V2
where Base is a base address and V2 is a vector of offsets from the
base.
2. Vector-of-addresses
This looks omsething like:
V1 <- Offset + V2
Where Offset is an offset value applied to each address in V2.
The first form is somewhat more convenient for striding through an array
while the second is somewhat more convenient for doing gather/scatter on
a set of "random" address locations (think oper...

[LLVMdev] Vectors of Pointers and Vector-GEP
Hi,
Following the discussion in last week's LLVM developers conference I started working on support for vectors-of-pointers. Vectors of pointers are needed for supporting scatter/gather operations and are the first step in the direction of supporting predicated architectures. In the attached patch, I change the LLVM-IR in order to support vectors-of-pointers and added basic support for
