            Bug ID: 97637
           Summary: Compiling with LTO causes a bigger binary
           Product: gcc
           Version: 10.2.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: lto
          Assignee: unassigned at gcc dot gnu.org
          Reporter: christer.solskogen at gmail dot com
                CC: marxin at gcc dot gnu.org
  Target Milestone: ---

I've been experimenting with amiberry
(https://github.com/midwan/amiberry/tree/dev) a Amiga emulator to compile it
with LTO. The emulator requires a ARM machine (Raspberry Pi will do)

The final binary are 0.4MB bigger when compiled with LTO. 
I've added "flto -march=native" to CFLAGS and "flto=$(shell nproc) $(CFLAGS)
-fuse-linker-plugin -fuse-ld=gold -Wl,--sort-common" to LDFLAGS.

I've tried with both gold and ld.bfd.
