From f3e8502cc18b4e8e49d99d6910c15c4d68658d1d 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. llvm-svn: 147861 --- llvm/lib/MC/MCExpr.cpp | 2 ++ 1 file changed, 2 insertions(+) (limited to 'llvm/lib/MC') diff --git a/llvm/lib/MC/MCExpr.cpp b/llvm/lib/MC/MCExpr.cpp index 00465153b3c..455c03d1614 100644 --- a/llvm/lib/MC/MCExpr.cpp +++ b/llvm/lib/MC/MCExpr.cpp @@ -17,6 +17,7 @@ #include "llvm/MC/MCSymbol.h" #include "llvm/MC/MCValue.h" #include "llvm/Support/Debug.h" +#include "llvm/Support/ErrorHandling.h" #include "llvm/Support/raw_ostream.h" using namespace llvm; @@ -216,6 +217,7 @@ StringRef MCSymbolRefExpr::getVariantKindName(VariantKind Kind) { case VK_Mips_GOT_PAGE: return "GOT_PAGE"; case VK_Mips_GOT_OFST: return "GOT_OFST"; } + llvm_unreachable("Invalid variant kind"); } MCSymbolRefExpr::VariantKind -- cgit v1.2.3
