[PATCH 1/3] AArch64: Update relocations for ILP32
- From: Will Newton <will dot newton at linaro dot org>
- To: libc-alpha at sourceware dot org
- Date: Tue, 18 Nov 2014 16:43:28 +0000
- Subject: [PATCH 1/3] AArch64: Update relocations for ILP32
- Authentication-results: sourceware.org; auth=none
- References: <1416329010-8683-1-git-send-email-will dot newton at linaro dot org>
The latest version of the binutils ELF header defines a new set of
dynamic relocations for ILP32 and renames some to make the naming
more uniform.
ChangeLog:
2014-11-18 Will Newton <will.newton@linaro.org>
Andrew Pinski <andrew.pinski@caviumnetworks.com>
