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.
