[LLVMdev] using the constant pool during select
In ARM, constants that are too large to be used as immediate are
usually placed in a constant pool and loaded.
What I am trying to do is to have a select function that checks the if
a constant can be an immediate and, if it can't, produces a load:

[LLVMdev] Altivec vs the type legalizer
Hi Dale, I think Bob is right: the type legalizer shouldn't be turning v16i8
into v16i32, what should happen is that the return type of the BUILD_VECTOR
continues to be v16i8, but the type of the operands changes to i32, so you
end up with a BUILD_VECTOR that takes 16 lots of i32, and produces a v16i8.
The target then has all the info it needs to produce the best code, but needs
to be careful
