            Bug ID: 85490
           Summary: Missing STAGE4_CFLAGS in bootstrap-cet.mk

           Version: 8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
          Assignee: unassigned at gcc dot gnu.org
          Reporter: hjl.tools at gmail dot com
                CC: igor.v.tsimbalist at intel dot com
            Blocks: 81652
  Target Milestone: ---
            Target: x86_64-*-*, i?86-*-*

Since profiledbootstrap uses

STAGEfeedback_CFLAGS = $(STAGE4_CFLAGS) -fprofile-use

bootstrap-cet.mk should define STAGE4_CFLAGS  to support profiledbootstrap
with CET.
