From 396618b43a85e12d290a90b181c6af5d7c0c5f11 Mon Sep 17 00:00:00 2001 From: Jakob Stoklund Olesen Date: Fri, 1 Jun 2012 23:28:30 +0000 Subject: Switch all register list clients to the new MC*Iterator interface. No functional change intended. Sorry for the churn. The iterator classes are supposed to help avoid giant commits like this one in the future. The TableGen-produced register lists are getting quite large, and it may be necessary to change the table representation. This makes it possible to do so without changing all clients (again). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157854 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/RegisterClassInfo.cpp | 5 ++--- 1 file changed, 2 insertions(+), 3 deletions(-) (limited to 'lib/CodeGen/RegisterClassInfo.cpp') diff --git a/lib/CodeGen/RegisterClassInfo.cpp b/lib/CodeGen/RegisterClassInfo.cpp index 17165fa726..d5b7f309db 100644 --- a/lib/CodeGen/RegisterClassInfo.cpp +++ b/lib/CodeGen/RegisterClassInfo.cpp @@ -50,9 +50,8 @@ void RegisterClassInfo::runOnMachineFunction(const MachineFunction &mf) { CSRNum.clear(); CSRNum.resize(TRI->getNumRegs(), 0); for (unsigned N = 0; unsigned Reg = CSR[N]; ++N) - for (const uint16_t *AS = TRI->getOverlaps(Reg); - unsigned Alias = *AS; ++AS) - CSRNum[Alias] = N + 1; // 0 means no CSR, 1 means CalleeSaved[0], ... + for (MCRegAliasIterator AI(Reg, TRI, true); AI.isValid(); ++AI) + CSRNum[*AI] = N + 1; // 0 means no CSR, 1 means CalleeSaved[0], ...
