[PATCH] backends: Add support for EM_PPC64 GNU_ATTRIBUTES.
- From: Mark Wielaard <mark at klomp dot org>
- To: elfutils-devel at sourceware dot org
- Cc: Mark Wielaard <mark at klomp dot org>

- Subject: [PATCH] backends: Add support for EM_PPC64 GNU_ATTRIBUTES.
- Authentication-results: sourceware.org; auth=none
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.
