I have tried to compile to assembler my source code with next flags:
1. -flto
2. -flto -ffat-lto-objects
3. -flto -fno-fat-lto-objects
Third one provides optimized slim LTO code as written in documentation, but I don't see any difference in the output assembly file between first and second, why?
OS: linux
Compiler: GCC 4.7
