From 52a250afa53215190e1714ee2c858ab0bbfa0953 Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Mon, 11 Dec 2017 09:45:30 +0100 Subject: [PATCH] efi_loader: helloworld.c: Reduce file size The efi linker script includes sections needed for the dynamic linker. However, in our EFI application environment we don't have a dynamic linker. So let's remove them. That way we save on 4k padding and reduce the file size of the hello world efi binary from ~4k to ~1k.
