Replace DT_PPC_TLSOPT with DT_PPC_OPT.
|
|
|
7ab123 |
|
|
|
7ab123 |
This removes the DT_PPC_TLSOPT/DT_PPC64_TLSOPT dynamic tag and replaces
|
|
|
7ab123 |
it with DT_PPC_OPT/DT_PPC64_OPT tag to provide the same functionality
|
|
|
7ab123 |
and more. This isn't backwards compatible, but the TLSOPT tag hasn't
|
|
|
7ab123 |
been used since the tls optimisation support was never submitted to
|
|
|
7ab123 |
glibc.
