From: Eric Christopher Date: Thu, 12 Mar 2015 21:04:46 +0000 (+0000) Subject: Migrate the AArch64 TargetRegisterInfo to its TargetMachine X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=94a887226dc9ea0e3b8386b59530b834c8b5c2a2;p=oota-llvm.git Migrate the AArch64 TargetRegisterInfo to its TargetMachine implementation. This requires a bit of scaffolding and a few fixups that'll go away once all of the ports have been migrated. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@232103 91177308-0d34-0410-b5e6-96231b3b80d8 --- diff --git a/lib/Target/AArch64/AArch64InstrInfo.cpp b/lib/Target/AArch64/AArch64InstrInfo.cpp index 8e0af2dd516..581a3b9a935 100644 --- a/lib/Target/AArch64/AArch64InstrInfo.cpp +++ b/lib/Target/AArch64/AArch64InstrInfo.cpp @@ -31,7 +31,7 @@ using namespace llvm; AArch64InstrInfo::AArch64InstrInfo(const AArch64Subtarget &STI) : AArch64GenInstrInfo(AArch64::ADJCALLSTACKDOWN, AArch64::ADJCALLSTACKUP), - RI(STI.getTargetTriple()), Subtarget(STI) {} + Subtarget(STI) {} /// GetInstSize - Return the number of bytes of code the specified /// instruction may be.
