Subject: [PATCH 06/27] [AARCH64] Use PTR_REG/PTR_SIZE/PTR_SIZE_LOG in dl-tlsesc.S
Date: Tue, 21 Jun 2016 08:06:50 +0300	[thread overview]
Message-ID: <1466485631-3532-8-git-send-email-ynorov@caviumnetworks.com> (raw)
In-Reply-To: <1466485631-3532-1-git-send-email-ynorov@caviumnetworks.com>

From: Andrew Pinski <apinski@cavium.com>

This converts dl-tlsdesc.S code over to use the new macros which allows for
sharing between ILP32 and LP64 code.

* sysdeps/aarch64/dl-tlsdesc.S (_dl_tlsdesc_return): Use PTR_REG.
(_dl_tlsdesc_undefweak): Use PTR_REG, PTR_SIZE.
(_dl_tlsdesc_dynamic): Likewise.
(_dl_tlsdesc_resolve_rela): Likewise.
(_dl_tlsdesc_resolve_hold): Likewise.
