Chris Lattner c7d7e0cbe0 make simplifycfg insert an llvm.trap before the 'unreachable' it introduces ... when it detects undefined behavior. llvm.trap generally codegens into some thing really small (e.g. a 2 byte ud2 instruction on x86) and debugging this sort of thing is "nontrivial". For example, we now compile: void foo() { *(int*)0 = 42; } into: _foo: pushl %ebp movl %esp, %ebp ud2 Some may even claim that this is a security hole, though that seems dubious to me. This addresses rdar://7958343 - Optimizing away null dereference potentially allows arbitrary code execution git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103356 91177308-0d34-0410-b5e6-96231b3b80d8		2010-05-08 22:15:59 +00:00
