[cfe-commits] [PATCH] [ubsan] Add support for -fsanitize-blacklist

[Richard Smith]

On the clang side, it seems messy and error-prone to distribute the
checking for blacklisting across all the callers of EmitCheck, but I
understand that you're trying to avoid generating the check condition
for blacklisted functions. Maybe we could make a separate struct
containing just the Sanitize* flags, and in the CodeGenFunction
constructor bind a reference to either the global set of flags or a
set of all-false flags, depending on whether we're blacklisted? This
would also make it easier to blacklist specific sanitizers in specific
functions later.
