            Bug ID: 18846
           Summary: gold PowerPC --emit-relocs differ from ld
           Product: binutils
           Version: 2.25
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gold

gold_ppc_rela_addend.patch

When using --emit-relocs on PowerPC, gold recalculates the addend in the
relocation entry to include the symbol value. When using ld the symbol value is
not added to the addend.

Example: readelf -r test.elf

 Offset     Info    Type            Sym.Value  Sym. Name + Addend
gold
010004e2  00000304 R_PPC_ADDR16_LO   010200c0   .bss + 1020140

ld
010004e2  00000304 R_PPC_ADDR16_LO   010200c0   .bss + 80


I attached a patch that solves this. I don't know if it's a copy past error or
if the changed behavior is intended.
