Subject: Tweak ppc32 tls_get_addr optimisation
X-Git-Tag: users/hjl/linux/release/2.25.51.0.2~2^2~36^2~13
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=f01f1741df37f0330fbf2809df0ffddc992ff60c;p=thirdparty%2Fbinutils-gdb.git

Tweak ppc32 tls_get_addr optimisation

This patch is cosmetic.  It prevents references to __tls_get_addr_opt
(an alias for __tls_get_addr) when the optimisation isn't possible.

	* elf32-ppc.c (ppc_elf_tls_setup): Set no_tls_get_addr_opt if
	not PLT_NEW.
