llvm-mirror/test/Assembler/auto_upgrade_intrinsics.ll
Elad Cohen 3908e15a8b Support arbitrary address space pointers in masked gather/scatter intrinsics. 
Fixes PR31789 - When loop-vectorize tries to use these intrinsics for a
non-default address space pointer we fail with a "Calling a function with a
bad singature!" assertion. This patch solves this by adding the 'vector of
pointers' argument as an overloaded type which will determine the address
space.
