Subject: Silence LLVM 14 API deprecation warnings.
X-Git-Url: http://git.postgresql.org/gitweb/static/gitweb.js?a=commitdiff_plain;h=a56e7b66010f330782243de9e25ac2a6596be0e1;p=users%2Frhaas%2Fpostgres.git

Silence LLVM 14 API deprecation warnings.

We are going to need to handle the upcoming opaque pointer API
changes[1], possibly in time for LLVM 15, but in the meantime let's
silence the warnings produced by LLVM 14.
