Rich Felker f4936735c5 SH FDPIC backend support
gcc/ChangeLog
	* config.gcc: Handle --enable-fdpic.
	* config/sh/constraints.md (Ccl): New constraint.
	* config/sh/linux.h (SUBTARGET_LINK_EMUL_SUFFIX): Handle -mfdpic.
	* config/sh/sh-c.c (sh_cpu_cpp_builtins): Add __FDPIC__ and
	__SH_FDPIC__.
	* config/sh/sh-mem.cc (expand_block_move): Support FDPIC for calls
	to library functions.
	* config/sh/sh-protos.h (function_symbol_result): New struct.
	(function_symbol): Return function_symbol_result.
	(sh_get_fdpic_reg_initial_val, sh_load_function_descriptor): New
	declarations.
	* config/sh/sh.c (TARGET_ASM_INTEGER, sh_assemble_integer):
	Implement target hook.
 	(TARGET_CANNOT_FORCE_CONST_MEM, sh_cannot_force_const_mem_p):
	Likewise.
	(sh_option_override): Force -fPIC if FDPIC is in effect.
 	(sh_asm_output_addr_const_extra): Add UNSPEC_GOTFUNCDESC and
	UNSPEC_GOTOFFFUNCDESC cases.
	(prepare_move_operands): Use FDPIC initial GOT register for
	TLS-related GOT access; inhibit cross-section address offset
	constants for FDPIC.
	(sh_assemble_integer): New function.
	(sh_cannot_copy_insn_p): Inhibit copying insns that are FDPIC
	PC-relative call sites.
	(expand_ashiftrt): Adapt invocation of function_symbol.
	(sh_expand_prologue): Inhibit PC-relative GOT address load for
	FDPIC.
	(nonpic_symbol_mentioned_p): Add cases for UNSPEC_GOTFUNCDESC and
	UNSPEC_GOTOFFFUNCDESC.
	(legitimize_pic_address): Resolve function symbols to function
	descriptors for FDPIC.  Do not use GOT-relative addressing for
	local data that may be read-only on FDPIC.

	(sh_trampoline_init): Generate FDPIC trampolines.
	(sh_function_ok_for_sibcall): Add TARGET_FDPIC check.
	(sh_expand_sym_label2reg): Don't assume sibcalls are local.
	(sh_output_mi_thunk): Generate FDPIC call.
	(function_symbol): Return function_symbol_result.  For
	SFUNC_STATIC on FDPIC, generate call site labels to use
	PC-relative addressing rather than GOT-relative addressing.
	(sh_conditional_register_usage): Make PIC register fixed and call used
	when FDPIC is in effect.
	(sh_legitimate_constant_p): Impose FDPIC
	constant constraints.
	(sh_cannot_force_const_mem_p, sh_load_function_descriptor)
	(sh_get_fdpic_reg_initial_val): New functions.
	* config/sh/sh.h (SUBTARGET_ASM_SPEC, SUBTARGET_LINK_EMUL_SUFFIX):
	Handle -mfdpic.
	(FDPIC_SELF_SPECS, SUBTARGET_DRIVER_SELF_SPECS)
	(PIC_OFFSET_TABLE_REG_CALL_CLOBBERED)
	(SH_OFFSETS_MUST_BE_WITHIN_SECTIONS_P): New macros.
	(DRIVER_SELF_SPECS): Add SUBTARGET_DRIVER_SELF_SPECS and
	FDPIC_SELF_SPECS.
	(TRAMPOLINE_SIZE): Select trampoline size for FDPIC.
	(ASM_PREFERRED_EH_DATA_FORMAT): Add EH format constraints for
	FDPIC.
	(ASM_MAYBE_OUTPUT_ENCODED_ADDR_RTX): Handle FDPIC case.
	* config/sh/sh.md (UNSPEC_GOTFUNCDESC, UNSPEC_GOTOFFFUNCDESC): New
	constants.
	(calli_fdpic, call_valuei_fdpic, sibcalli_fdpic)
	(sibcalli_pcrel_fdpic, sibcall_pcrel_fdpic, sibcall_valuei_fdpic)

	*divsi_inv_call_combine, divsi3_i4, divsi3_i4_single, divsi3)
	(ashlsi3, ashlsi3_d_call, ashrsi3_n, lshrsi3, lshrsi3_d_call)
	(calli, call_valuei, call, call_value, sibcalli, sibcalli_pcrel)
	(sibcall_pcrel, sibcall, sibcall_valuei, sibcall_valuei_pcrel)

	(block_move_real_i4, block_lump_real_i4): Add support for FDPIC
	calls.
	(mulsi3, ic_invalidate_line, initialize_trampoline, call_pop,
	call_value_pop): Adjust for new function_symbol signature.
	* config/sh/sh.opt (-mfdpic): New option.
	* doc/install.texi (Options specification): Document
	--enable-fdpic.
	* doc/invoke.texi (SH Options): Document -mfdpic.

include/ChangeLog:
	* longlong.h (udiv_qrnnd): Add FDPIC compatible version for SH.

libitm/ChangeLog:
	* config/sh/sjlj.S (_ITM_beginTransaction): Bypass PLT calling
	GTM_begin_transaction for compatibility with FDPIC.

		   README for GNU development tools

This directory contains various GNU compilers, assemblers, linkers, 
debuggers, etc., plus their support routines, definitions, and documentation.

If you are receiving this as part of a GDB release, see the file gdb/README.
If with a binutils release, see binutils/README;  if with a libg++ release,
see libg++/README, etc.  That'll give you info about this
package -- supported targets, how to use it, how to report bugs, etc.

It is now possible to automatically configure and build a variety of
tools with one command.  To build all of the tools contained herein,
run the ``configure'' script here, e.g.:

	./configure 
	make

To install them (by default in /usr/local/bin, /usr/local/lib, etc),
then do:
	make install

(If the configure script can't determine your type of computer, give it
the name as an argument, for instance ``./configure sun4''.  You can
use the script ``config.sub'' to test whether a name is recognized; if
it is, config.sub translates it to a triplet specifying CPU, vendor,
and OS.)

If you have more than one compiler on your system, it is often best to
explicitly set CC in the environment before running configure, and to
also set CC when running make.  For example (assuming sh/bash/ksh):

	CC=gcc ./configure
	make

A similar example using csh:

	setenv CC gcc
	./configure
	make

Much of the code and documentation enclosed is copyright by
the Free Software Foundation, Inc.  See the file COPYING or
COPYING.LIB in the various directories, for a description of the
GNU General Public License terms under which you can copy the files.

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
