+
+ Sparc64 merge:
+ * configure.in: Change up subdirectories, rename sparc8->sparcv8.
+
+ * csu/Makefile: Nuke need-nopic-initfini bits. The problem was
+ that sparc64 ld did not recognize pic relocs at all.

+ * elf/dl-deps.c: Include <string.h>.
+ * elf/do-rel.h (elf_dynamic_do_rel): Take reloc address and size
+ directly instead of the DT names to get them from.
+ * elf/dynamic-link.h (_ELF_DYNAMIC_DO_RELOC): New macro distilled
+ from ELF_DYNAMIC_DO_REL{,A}. Define a second version that accounts
+ for the possibility that DT_RELA and DT_JMPPLT overlap, as such is
+ the case on the Sparc.
+
+ * elf/elf.h: Stub out Elf64_Ver*, and make them the same as the
+ Elf32_Ver* bits. The linker does not even know to differentiate
+ between the word sizes. Someone should examine this and figure
+ out what the proper sizes of things should be for 64-bit hosts
+ before the sparc64 libraries are distributed.
+
+ * shlib-versions: Rename sparc64 ld.so to not conflict with sparc32
+ on the same machine.

+ Move old sysdeps/sparc contents to sysdeps/sparc/sparc32,
+ rename sparc8 subdir to sparcv8, move sysdeps/sparc64 content to
+ sysdeps/sparc/sparc64. Same for sysdeps/unix/sysv/linux/sparc.

+
+ * sysdeps/sparc/sparc32/dl-machine.h (elf_machine_load_address):
+ Use uninitialized .got to find load address instead of AT_BASE, as
+ the later does not exist when running ld.so directly.
+
+ * sysdeps/sparc/sparc32/fpu/fpu_control.h: Move from ../.
+ * sysdeps/sparc/sparc64/fpu/fpu_control.h: Likewise.

+ and setjmp entry points.
+
+ * sysdeps/sparc/sparc64/dl-machine.h: Finish real implementation.
+
+ * sysdeps/sparc/sparc64/elf/crtbegin.S: Add copyright, fix PIC.
