Subject: [Lanai] Remove dead functions from LanaiRegisterInfo
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=e2aa191ac4d1725a2251b169634ba769ec1becc6;p=llvm

[Lanai] Remove dead functions from LanaiRegisterInfo

getEHExceptionRegister and getEHHandlerRegister are unused and were removed
from most backends in rL192099. This patch removes them from Lanai.

Differential Revision: https://reviews.llvm.org/D36829
