* elfcode.h (elf_object_p): Also restore the bfd mach field on
to the relocation offset. Its interpretation is dependent upon
the howto. For example, on the 68k the code:
-
| char foo[];
| main()
| {
| unlk fp
| rts
-
This could create a reloc pointing to <<foo>>, but leave the
offset in the data, something like:
-
|RELOCATION RECORDS FOR [.text]:
|offset type value
|00000006 32 _foo
|0000000c 4e5e ; unlk fp
|0000000e 4e75 ; rts
-
Using coff and an 88k, some instructions don't have enough
space in them to represent the full address range, and
pointers have to be loaded in two parts. So you'd get something like:
-
| or.u r13,r0,hi16(_foo+0x12345678)
| ld.b r2,r13,lo16(_foo+0x12345678)
| jmp r1
-
This should create two relocs, both pointing to <<_foo>>, and with
0x12340000 in their addend field. The data would consist of:
-
|RELOCATION RECORDS FOR [.text]:
|offset type value
|00000002 HVRT16 _foo+0x12340000
|00000004 1c4d5678 ; ld.b r2,r13,0x5678
|00000008 f400c001 ; jmp r1
-
The relocation routine digs out the value from the data, adds
it to the addend to get the original offset, and then adds the
value of <<_foo>>. Note that all 32 bits have to be kept around
Both relocs contain a pointer to <<foo>>, and the offsets
contain junk.
-
|RELOCATION RECORDS FOR [.text]:
|offset type value
|00000004 HI22 _foo+0x12345678
|0000000c 81c7e008 ; ret
|00000010 81e80000 ; restore
