Linking with ld.lld via $ make LD=ld.lld produces the warning: ld.lld: warning: cannot find entry symbol _start; defaulting to 0x1000
Linking with ld.bfd shows the default entry is 0x1000: $ readelf -h arch/x86/realmode/rm/realmode.elf | grep Entry Entry point address: 0x1000 While ld.lld is being pedantic, just set the entry point explicitly, instead of depending on the implicit default. Link: https://github.com/ClangBuiltLinux/linux/issues/216 Signed-off-by: Nick Desaulniers <ndesaulni...@google.com> --- Changes V1 -> V2: * Use command line flag, rather than linker script, as ld.bfd produces a syntax error for `ENTRY(0x1000)` but is happy with `-e 0x1000` arch/x86/realmode/rm/Makefile | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/x86/realmode/rm/Makefile b/arch/x86/realmode/rm/Makefile index f60501a384f9..338a00c5257f 100644 --- a/arch/x86/realmode/rm/Makefile +++ b/arch/x86/realmode/rm/Makefile @@ -46,7 +46,7 @@ $(obj)/pasyms.h: $(REALMODE_OBJS) FORCE targets += realmode.lds $(obj)/realmode.lds: $(obj)/pasyms.h -LDFLAGS_realmode.elf := -m elf_i386 --emit-relocs -T +LDFLAGS_realmode.elf := -m elf_i386 --emit-relocs -e 0x1000 -T CPPFLAGS_realmode.lds += -P -C -I$(objtree)/$(obj) targets += realmode.elf -- 2.23.0.351.gc4317032e6-goog
