Bradley Smith	48f5a392cb	[IR] Add vscale_range IR function attribute ... This attribute represents the minimum and maximum values vscale can take. For now this attribute is not hooked up to anything during codegen, this will be added in the future when such codegen is considered stable. Additionally hook up the -msve-vector-bits=<x> clang option to emit this attribute. Differential Revision: https://reviews.llvm.org/D98030	2021-03-22 12:05:06 +00:00
