6614f9f559
* config/bfin/bfin.opt (mfdpic): New option. * config/bfin/t-bfin-elf (EXTRA_PARTS): Add crtbeginS.o and crtendS.o. (EXTRA_MULTILIB_PARTS): Likewise. (CRTSTUFF_T_CFLAGS, TARGET_LIBGCC2_CFLAGS): Use -fpic. (MULTILIB_OPTIONS, MULTILIB_EXCEPTIONS): Build one extra -mfdpic multilib. * config/bfin/elf.h (STARTFILE_SPEC): Don't link in crt0.o if -shared. (CRT_CALL_STATIC_FUNCTION): New. * config/bfin/uclinux.h (STARTFILE_SPEC): Don't link in crt0.o if -shared. (CRT_CALL_STATIC_FUNCTION): New. * config/bfin/bfin.c (legitimize_pic_address): Now static. Handle FD-PIC moves. (n_pregs_to_save): PIC register doesn't need to be saved with FD-PIC. (print_operand): Handle UNSPEC_MOVE_FDPIC and UNSPEC_FUNCDESC_GOT17M4. (initialize_trampoline): Changed to handle FD-PIC code generation. (expand_move): If TARGET_FDPIC, use emit_pic_move as needed. (bfin_expand_call): Generate FD-PIC calls if TARGET_FDPIC. (override_options): Disallow -mid-shared-library -mfdpic combination. Can't do unaligned ops if FD-PIC. Turn off flag_pic if trying to generate non-id-shared-library non-fdpic code, since it's not supported. (bfin_assemble_integer): New function. (TARGET_ASM_INTEGER): Define. * config/bfin/crti.s (__init, __fini): Save P3 on the stack if __BFIN_FDPIC__. * config/bfin/crtn.s: Restore them. * config/bfin/bfin.h (TARGET_CPU_CPP_BUILTINS): Define __BFIN_FDPIC__ if TARGET_FDPIC. (DRIVER_SELF_SPECS, SUBTARGET_DRIVER_SELF_SPECS, LINK_GCC_C_SEQUENCE_SPEC, ASM_SPEC, LINK_SPEC): New macros. (FDPIC_FPTR_REGNO, FDPIC_REGNO, OUR_FDPIC_REG): New macros. (TRAMPOLINE_SIZE, TRAMPOLINE_TEMPLATE): Adjust for FD-PIC. (CONDITIONAL_REGISTER_USAGE): If TARGET_FDPIC, FDPIC_REGNO is call-used. (enum reg_class, REG_CLASS_CONTENTS, REG_CLASS_NAMES): Add FDPIC_REGS and FDPIC_FPTR_REGS. (REG_CLASS_FROM_LETTER): Use 'Z' and 'Y' for them. * config/bfin/bfin.md (UNSPEC_MOVE_FDPIC, UNSPEC_FUNCDESC_GOT17M4, UNSPEC_VOLATILE_LOAD_FUNCDESC): New constants. (load_funcdescsi): New pattern. (call_symbol_fdpic, sibcall_symbol_fdpic, call_value_symbol_fdpic, sibcall_value_symbol_fdpic, call_insn_fdpic, sibcall_insn_fdpic, call_value_insn_fdpic, sibcall_value_insn_fdpic): New patterns.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the file COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs.html for how to report bugs usefully.
