From b1042ce216eaef96099f263fb81141dbdec004fd Mon Sep 17 00:00:00 2001 From: Mark Wielaard Date: Wed, 15 Feb 2017 14:30:27 +0100 Subject: [PATCH] backends: Add support for EM_PPC64 GNU_ATTRIBUTES. ppc64 and ppc64le ELF files can also contain a power specific .gnu.attributes section. Add support for those and recognize the new GNU_Power_ABI_FP Single-precision hard float value.
