PowerPC64 --plt-align
Alignment of plt stubs was broken, firstly because the option was
being dropped due to the alignment value not being set in the "params"
struct used in elf64-ppc.c, and secondly due to not calculating the
number of alignment boundary crossings correctly.
bfd/
* elf64-ppc.c (plt_stub_pad): Correct.
ld/
* ld.texinfo: Correct --plt-align documentation.
* emultempl/ppc64elf.em (plt_stub_align): Delete. Use and set
params.plt_stub_align instead.
