[cfe-commits] adding attribute no_address_safety_analysis, please review

[Kostya Serebryany]

Hello,

The following patch adds __attribute__((no_address_safety_analysis)) which
will allow to disable
address safety analysis (such as e.g. AddressSanitizer or SAFECode) for a
specific function.

When building with AddressSanitizer, add AddressSafety function attribute
to every generated function
except for those that have __attribute__((no_address_safety_analysis)).

With this patch we will be able to
1. disable AddressSanitizer for a particular function
2. disable AddressSanitizer-hostile optimizations (such as some cases of
load widening) when AddressSanitizer is on.
