Fariborz Jahanian 2b9fc83db5 Fixes a code gen bug related to accessing a now 
non-existing 'isa' field of a non-existing struct type
all related to legacy type definition for 'id' which we have
dropped in clang in favor of a built-in type.
(fixes radar 7470820).

Chris Lattner 2f3da9b205 update to match LLVM API change: 
Remove isPod() from DenseMapInfo, splitting it out to its own
isPodLike type trait.  This is a generally useful type trait for
more than just DenseMap, and we really care about whether something
acts like a pod, not whether it really is a pod.

-fcatch-undefined-behavior if we aren't optimizing.  WIP.

Anders Carlsson adbe4249d6 Fix regression in my last commit - if a struct has a trivial destructor but no usual deallocation function we don't need a cookie.

Anders Carlsson 21122cf657 More array cookie improvements. 
llvm-svn: 91247
 2009-12-13 20:04:38 +00:00
Anders Carlsson f5af8dead7 If the usual array deallocation function of a class takes two arguments, we need to pass the number of bytes allocated to the deallocation function, just not the number of bytes in a single element.

Jeffrey Yasskin 1615d45daa Un-namespace-qualify llvm_unreachable. It's a macro, so the qualification gave 
no extra safety anyway.

Mike Stump d954638f02 Implement runtime checks for undefined behavior. WIP. 
This implements a new flag -fcatch-undefined-behavior.  The flag turns
on additional runtime checks for:

  T a[I];

  a[i]    abort when i < 0 or i >= I.

Future stuff includes shifts by >= bitwidth amounts.

Anders Carlsson fd7dfeb779 Improve linkage of RTTI data structures. Introduce CodeGenModule::GetAddrOfRTTI which figures out the right linkage of the RTTI information for the given type and whether it should be defined or not. I will migrate clients over to GetAddrOfRTTI in subsequent commits (with tests).
