<pre>sys/boot/efi/boot1 loader hangs in QEMU if linked with lld.
I was able to reduce its code to minimal case:
#include <sys/param.h>
#include <machine/elf.h>
#include <machine/stdarg.h>
#include <stand.h>
#include <efi.h>
#include <eficonsctl.h>
#include "boot_module.h"
EFI_STATUS efi_main(EFI_HANDLE Ximage, EFI_SYSTEM_TABLE* Xsystab);
EFI_SYSTEM_TABLE *systab;
EFI_BOOT_SERVICES *bs;
static EFI_HANDLE *image;
EFI_STATUS
efi_main(EFI_HANDLE Ximage, EFI_SYSTEM_TABLE *Xsystab)
{
SIMPLE_TEXT_OUTPUT_INTERFACE *conout = NULL;
systab = Xsystab;
image = Ximage;
bs = Xsystab->BootServices;
//conout = Xsystab->ConOut; //1
conout = systab->ConOut; //2
conout->Reset(conout, TRUE);
return EFI_SUCCESS;
}
Now note that if line 1 is used, lld linked loader hangs. If line 2 is used, it
does not.
ld.bfd linked loader feels fine with any of these lines.
I am investigating the difference in output now.</pre>
