Based on experience on Debian (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=960157) Docker image I found I was required to use "-flto-binary=/usr/lib/LLVMgold.so" in addition to "-flto=full".
Is it Debian specific issue or required for other distributions as well?
For example on Archlinux the liblphobos package provides two files:
So probably adding "-defaultlib=phobos2-ldc-lto,druntime-ldc-lto" will be fine.
But is "-flto-binary" is still required? What is it used for?
Can we please improve some information about proper flags usage for LTO enabled code in LDC?
