* configure.ac: Add --enable-secureplt.
(HAVE_AS_REL16): Test for R_PPC_REL16 relocs. * config.in: Regenerate. * configure: Regenerate. * config.gcc (powerpc64-*-linux*, powerpc-*-linux*): Add rs6000/secureplt.h to tm_file when enable_secureplt. * doc/invoke.texi (msecure-plt, mbss-plt): Document. * doc/install.texi: Document --enable-targets and --enable-secureplt. Correct xrefs to "Using the GNU Compiler Collection (GCC)". * config/rs6000/secureplt.h: New file. * config/rs6000/sysv4.h (TARGET_SECURE_PLT): Define. (SUBTARGET_OVERRIDE_OPTIONS): Error if -msecure-plt given without assembler support. (CC1_SECURE_PLT_DEFAULT_SPEC): Define. (CC1_SPEC): Delete duplicate mno-sdata. Invoke cc1_secure_plt_default. (SUBTARGET_EXTRA_SPECS): Add cc1_secure_plt_default. * config/rs6000/sysv4.opt (msecure-plt, bss-plt): Add options. * config/rs6000/rs6000.h (TARGET_SECURE_PLT): Define. * config/rs6000/rs6000.c (rs6000_emit_load_toc_table): Handle TARGET_SECURE_PLT got register load sequence. (rs6000_emit_prologue): Call rs6000_emit_load_toc_table when TARGET_SECURE_PLT. (rs6000_elf_declare_function_name): Don't emit toc address offset word when TARGET_SECURE_PLT. * config/rs6000/rs6000.md (elf_high, elf_low): Move past load_toc_*. (load_toc_v4_PIC_1) Enable for TARGET_SECURE_PLT. (load_toc_v4_PIC_3b, load_toc_v4_PIC_3c): New insns. (call, call_value): Mark pic_offset_table_rtx used for sysv pic and TARGET_SECURE_PLT. (call_nonlocal_sysv, call_value_nonlocal_sysv, sibcall_nonlocal_sysv, sibcall_value_nonlocal_sysv): Add 32768 offset when TARGET_SECURE_PLT and -fPIC. * config/rs6000/tramp.asm (trampoline_initial): Use "bcl 20,31". (__trampoline_setup): Likewise. Init r30 before plt call. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@100415 138bc75d-0d04-0410-961f-82ee72b054a4
