Fixes powerpc64le ld segfaults when --emit-relocs is used.
|
||
|
|
|
||
|
|
ELFv2 needs fewer relocs to annotate plt call stubs. I correctly
|
||
|
|
allocated a smaller buffer and wrote the proper relocs, but stupidly
|
||
|
|
bumped the reloc count as for ELFv1.
|
||
|
|
|
||
|
|
* elf64-ppc.c (ppc_build_one_stub): Correct reloc count passed
|
||
|
|
to get_relocs for ELFv2.
