Update.
2004-01-14 Steven Munroe <sjmunroe@us.ibm.com> * include/libc-symbols.h [HAVE_ASM_GLOBAL_DOT_NAME] (_symbol_version): Use C_SYMBOL_DOT_NAME to create '.'ed symbols. (_default_symbol_version): Use C_SYMBOL_DOT_NAME to create '.'ed symbols. * sysdeps/powerpc/Makefile: Add rtld-global-offsets.sym to gen-as-const-headers. * sysdeps/powerpc/elf/rtld-global-offsets.sym: New file. * sysdeps/powerpc/sysdep.h: Define v# symbols for vector registers. Define PPC_FEATURE_* masks for Aux Vector AT_HWCAP. * sysdeps/unix/sysv/linux/kernel-features.h (__ASSUME_SWAPCONTEXT_SYSCALL): Define for PPC and 2.6.0 kernels. * sysdeps/unix/sysv/linux/powerpc/sys/ucontext.h [!__WORDSIZE == 32]: Declare mcontext_t inline and include altivec state for 64-bit. * sysdeps/unix/sysv/linux/powerpc/powerpc64/Versions: Add GLIBC_2.3.4 versions for setcontext, getcontext, and swapcontext. * sysdeps/unix/sysv/linux/powerpc/powerpc64/Versions: Add GLIBC_2.3.4 versions for setcontext, getcontext, swapcontext, and makecontext. * sysdeps/unix/sysv/linux/powerpc/powerpc64/getcontext.S (__getcontext): Upgrade to save Altivec regs and version GLIBC_2_3_4. [SHLIB_COMPAT (libc, GLIBC_2_3, GLIBC_2_3_4)](__novec_getcontext): Compatible with GLIBC_2.3.3 release. * sysdeps/unix/sysv/linux/powerpc/powerpc64/makecontext.S (__makecontext): Use parm save area instead of compiler_dw to hold context pointer. * sysdeps/unix/sysv/linux/powerpc/powerpc64/setcontext.S (__setcontext): Upgrade to restore Altivec regs and version GLIBC_2_3_4. [SHLIB_COMPAT (libc, GLIBC_2_3, GLIBC_2_3_4)](__novec_setcontext): Compatible with GLIBC_2.3.3 release. * sysdeps/unix/sysv/linux/powerpc/powerpc64/swapcontext.S (__swapcontext): Upgrade to swap Altivec regs and version GLIBC_2_3_4.
