* elf32-spu.c (spu_elf_special_sections): Add "._ea". (spu_elf_relocate_section): Handle relocations against symbols defined in ._ea specially. binutils/ * embedspu.sh: Take note of R_SPU_PPU32/64 relocs without a symbol, and if present, put image in ".data.speelf". Put program handle in ".data.spehandle". ld/emulparams/ * elf32_spu.sh (OTHER_SECTIONS): Add "._ea". * elf32ppc.sh: If building with spu support, put ".data.spehandle" sections at the start of ".data" and provide a symbol to locate the directory of embedded spe programs. ld/testsuite/ * ld-spu/ear.s: Align various sections. * ld-spu/embed.rd: Update.
