2015-04-23	Align .TOC. for PowerPC64	Alan Modra	1	-3/+3
	This change, with prerequisite 0e5fabeb, provides a toc base aligned to 256 bytes rather than 8 bytes. This is necessary for a minor gcc optimisation, allowing use of d-form instructions to correctly access toc-relative items larger than 8 bytes. bfd/ * elf64-ppc.c (TOC_BASE_ALIGN): Define.

2014-03-05	Support R_PPC64_ADDR64_LOCAL	Alan Modra	1	-0/+41
	This adds support for "func@localentry", an expression that returns the ELFv2 local entry point address of function "func". I've excluded dynamic relocation support because that obviously would require glibc changes. include/elf/ * ppc64.h (R_PPC64_REL24_NOTOC, R_PPC64_ADDR64_LOCAL): Define. bfd/ * elf64-ppc.c (ppc64_elf_howto_raw): Add R_PPC64_ADDR64_LOCAL entry.
