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/Support/APFloat.cpp | 1 + 1 file changed, 1 insertion(+) (limited to 'lib/Support/APFloat.cpp') diff --git a/lib/Support/APFloat.cpp b/lib/Support/APFloat.cpp index f4ca0fb014..8913dd6def 100644 --- a/lib/Support/APFloat.cpp +++ b/lib/Support/APFloat.cpp @@ -1172,6 +1172,7 @@ APFloat::roundAwayFromZero(roundingMode rounding_mode, case rmTowardNegative: return sign == true; } + llvm_unreachable("Invalid rounding mode found"); } APFloat::opStatus -- cgit v1.2.3-70-g09d2
