[PATCH] D36829: [Lanai] Remove dead functions from LanaiRegisterInfo

[Alex Bradbury via Phabricator via llvm-commits]

asb created this revision.

getEHExceptionRegister and getEHHandlerRegister are unused and were removed from most backends in https://reviews.llvm.org/rL192099. This patch removes them from Lanai.
