From 38842eab49794d04186e3ca51a18090ba9ee5383 Mon Sep 17 00:00:00 2001 From: Heiko Stuebner Date: Wed, 26 Oct 2022 13:18:37 +0200 Subject: [PATCH 1/7] efi/riscv: libstub: mark when compiling libstub We want to runtime-optimize some core functions (str*, mem*) but not have this leak into libstub. Instead libstub for the short while it's running should just use the generic implementation. To be able to determine whether functions are getting compiled as part of libstub or not, add a compile-flag we can check via #ifdef.
