Subject: [PATCH] Make link time optimization flags configurable
|
|
|
|
We want to use -flto=auto in Arch Linux to speed up building, but we
|
|
can't hardcode it in buildenv/lto.sh because other downstreams might
|
|
have clang < 13.0.0 which did not recognize -flto=auto as equivalent
|
|
to -flto=full.
|
|
|
|
Introducing an LTOFLAGS variable to makepkg.conf seems the way to go.
