[llvm-commits] [PATCH] AddressSanitizer Initialization Order Checking

[Reid Watson]

Kostya,

I completely missed that (caught in a poorly written email filter).
Thanks for reviewing it for me, and I'll use rietveld when submitting
the update d version.
I'm looking at the code now, and I'll update when I've implemented the
suggested changes.
