PowerPC64 __tls_get_addr_desc

Browse Source 
This implements register saving and restoring in the __tls_get_addr
call stub, so that when glibc supports the optimized tls call stub gcc
can generate code that assumes only r0, r12 and of course r3 are
changed on a __tls_get_addr call.  When gcc expects __tls_get_addr
calls to preserve registers the call will be to __tls_get_addr_desc,
which will be translated by the linker to a call to __tls_get_addr_opt.

These options control how PowerPC64 @command{ld} uses a special

an optimization that allows the second and subsequent calls to
@code{__tls_get_addr} for a given symbol to be resolved by the special
stub without calling in to glibc. By default the linker enables this
option when glibc advertises the availability of __tls_get_addr_opt.

@option{--tls-get-addr-regsave} forces generation of a stub that saves
and restores volatile registers around the call into glibc. Normally,
this is done when the linker detects a call to __tls_get_addr_desc.
Such calls then go via the register saving stub to __tls_get_addr_opt.
@option {--no-tls-get-addr-regsave} disables generation of the
