From a24f44c96603aff88e235e5ea46285e84aeb85f5 Mon Sep 17 00:00:00 2001 From: Leonard Chan <leonardchan@google.com> Date: Thu, 20 Jun 2019 19:44:51 +0000 Subject: [PATCH] [clang][NewPM] Do not eliminate available_externally durng `-O2 -flto` runs This fixes CodeGen/available-externally-suppress.c when the new pass manager is turned on by default. available_externally was not emitted during -O2 -flto runs when it should still be retained for link time inlining purposes. This can be fixed by checking that we aren't LTOPrelinking when adding the EliminateAvailableExternallyPass.
