[PATCH] D15728: [cfi] Support for dlopen and dlclose

[Evgeniy Stepanov via llvm-commits]

eugenis updated this revision to Diff 45288.
eugenis added a comment.

The previous approach contained a data race on the shadow pointer, which can not be updated without a lock in __cfi_slowpath. That would not be acceptable performance-wise. Probably.

This new version is linux-only as it requires mremap().
