            Bug ID: 87419
           Summary: -mfentry generates assembly codes as string instead of
                    RTL
           Product: gcc
           Version: 9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: hjl.tools at gmail dot com
                CC: wei3.xiao at intel dot com, xuepeng.guo at intel dot com
  Target Milestone: ---
            Target: i386,x86-64

FUNCTION_PROFILER, aka x86_function_profiler, used by -mfentry,
generates assembly codes as strings.  It is better for -mfentry
to generate RTLs instead.
