[PATCH] D46326: ThinLTO+CFI: short-circuit direct calls to jump table entries

[Vlad Tsyrklevich via llvm-commits]

Based on a quick look at a couple of stack traces it looks like some direct
calls now call symbols that are no longer overriden by their replacements
in chromium, e.g. calls to realloc() from a DSO previously resolved to the
tcmalloc implementation in chromium instead of realloc.cfi(), the locally
linked tcmalloc implementation in that library.
