Subject: [Bug target/97327] New: -mcpu=cortex-m55 warns without -mfloat-abi=hard or -march=armv8.1-m.main
Date: Wed, 07 Oct 2020 21:52:00 +0000	[thread overview]
Message-ID: <bug-97327-4@http.gcc.gnu.org/bugzilla/> (raw)

            Bug ID: 97327
           Summary: -mcpu=cortex-m55 warns without -mfloat-abi=hard or
                    -march=armv8.1-m.main
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: clyon at gcc dot gnu.org
  Target Milestone: ---

When compiling with
-mthumb -mcpu=cortex-m55
I get:
cc1: warning: switch '-mcpu=cortex-m55' conflicts with '-march=armv8.1-m.main'
switch

unless I add -mfloat-abi=hard
or -march=armv8.1-m.main 
which is a bit counter-intuitive.
