[LLVMdev] Vectorizing alloca instructions
...ut, i32 %index) {
entry:
%0 = extractelement <4 x i32> <i32 0, i32 1, i32 2, i32 3>, i32 %index
store i32 %0, i32 addrspace(1)* %out
}
I've slightly modified the SLPVectorizer (see the attached patch) so
that it will vectorize small trees, and I've also fixed a crash in the
BoUpSLP::Gather() function when it is passed a list of store
instructions. With this patch, the command:
opt -slp-vectorizer -debug -march=r600 -mcpu=redwood -o - vector-alloca.ll -S -slp-threshold=-20
Produces the following output and the program remains unchanged:

...tly about
getting the SLPVectorizer to handle the dynamic GEP. As soon as it does
that, everything else will fall away.
Not sure how much this helps, just wanted to point it out.
