I am currently playing with Alienware 15 R2 with the following CPU: Intel(R) Core(TM) i7-6820HK. Interestingly, my preliminary experiments indicate that adding MPX bounds checking via Pointer Checker in gcc is usually

...inion here is too biased) I am glad that LLVM already has the support for MPX instructions, but I see no good reason to add the MPX-based checker to LLVM. Yes, it will allow us to detect intra-object overflows, something that asan can not do by default <https://github.com/google/sanitizers/wiki/AddressSanitizerIntraObjectOverflow>, but it's not worth the extreme complexity of the MPX-based checker. --kcc On Thu, Jan 28, 2016 at 9:14 AM, David Chisnall via llvm-dev < llvm-dev at lists.llvm.org> wrote: > On 28 Jan 2016, at 17:03, Dmitrii Kuvaiskii via llvm-dev < > llvm-dev at lists.llvm.org> wrote:...
