From 732f05c41f177a0bc4d47e93a5d02120f146cb4c Mon Sep 17 00:00:00 2001 From: Chandler Carruth Date: Tue, 10 Jan 2012 18:08:01 +0000 Subject: Add 'llvm_unreachable' to passify GCC's understanding of the constraints of several newly un-defaulted switches. This also helps optimizers (including LLVM's) recognize that every case is covered, and we should assume as much. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147861 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/Spiller.cpp | 1 + 1 file changed, 1 insertion(+) (limited to 'lib/CodeGen/Spiller.cpp') diff --git a/lib/CodeGen/Spiller.cpp b/lib/CodeGen/Spiller.cpp index ec44d87a20..260eceab8a 100644 --- a/lib/CodeGen/Spiller.cpp +++ b/lib/CodeGen/Spiller.cpp @@ -194,4 +194,5 @@ llvm::Spiller* llvm::createSpiller(MachineFunctionPass &pass, case trivial: return new TrivialSpiller(pass, mf, vrm); case inline_: return createInlineSpiller(pass, mf, vrm); } + llvm_unreachable("Invalid spiller optimization"); } -- cgit v1.2.3
