However, commit # 450e7dd4001f ("powerpc/prom_init: don't use string functions from # lib/") copied memcmp as prom_memcmp to avoid KASAN instrumentation so # having bcmp be resolved to regular memcmp would break that assumption. # Furthermore, because the compiler is the one that inserted bcmp, we # cannot provide something like prom_bcmp. # # To prevent LLVM from being clever with optimizations like this, use # -ffreestanding to tell LLVM we are not hosted so it is not free to # make transformations like this. # # Reviewed-by: Nick Desaulneris <ndesaulniers@google.com> # Signed-off-by:
