hpt27xx_lib.o
I found that when tried to link kernel.
Minimal reproduce is:
-flavor gnu -o kernel.debug hpt27xx_lib.o
File is attached.
Problem is that file contains symbols which combines STT_SECTION and
are associated with a SHT_RELA/SHT_STRTAB/SHT_SYMTAB sections.
And we do not create section for those and that triggers this error.
For example:
Section {
Index: 2
Name: .rela.text (27)
Type: SHT_RELA (0x4)
Flags [ (0x0)
]
Address: 0x0
Offset: 0x9C138
Size: 220176
Link: 14
Info: 1
AddressAlignment: 8
EntrySize: 24
}
Symbol {
Name: (0)
Value: 0x0
Size: 0
Binding: Local (0x0)
Type: Section (0x3)
Other: 0
Section: .rela.text (0x2)
}
There are in total 7 symbols affected in this file assotiated with one of next
sections:
.rela.text, .rela.rodata, .rela.data, .rela.eh_frame, .shstrtab, .symtab,
.strtab</pre>
