llvm-6502/test/CodeGen/X86/unreachable-stack-protector.ll
Cameron Zwarich 53aac15a60 Fix the GCC test suite issue exposed by r127477, which was caused by stack
protector insertion not working correctly with unreachable code. Since that
revision was rolled out, this test doesn't actual fail before this fix.
