I think I have found the problem. It is related to the patch Ed sent. The new LD looks like it automagically turns on the --build-id option. I have not found out how turn it off. When this option is used it generates the .note.gnu.build-id section. When this section was discarded in the first ld pass (linuxbios_rom.ram creation) it was causing the segmentation fault crash. It looks like this same option is being called again when crt0.o is linked to create linuxbios. I have added the .note.gnu.build-id section to the .id section in the ldscript.ld file. SECTIONS { . = (_ROMBASE + ROM_IMAGE_SIZE - 0x10) - (__id_end - __id_start); .id (.) : { *(.id) *(.note.gnu.build-id) }
This has gotten me past the second crash but now linuxbios.strip is crashing.
Well done.
nm -n linuxbios | sort > linuxbios.map objcopy --gap-fill 0xff -O binary linuxbios linuxbios.strip objcopy: linuxbios.strip: Bad value objcopy: linuxbios.strip: Bad value make[1]: *** [linuxbios.strip] Error 1
So this does not look like a ld problem, but an added feature to ld is causing us grief. If anyone can figure out how to turn this option off, that may fix all of this without any patches... :-)
Still, it would be a nice gesture to the binutils guys to report it as a bug. Maybe there's some bug deeper down which triggers this.
