    • compiler: fix missing case in Array_type::get_value_pointer · 36f1a35f 
          
    Update the code in Array_type::get_value_pointer that handles
    "lvalue" context to look for both regular var expressions
    and temp var expressions, since both can appear in array/slice
    index expressions on the left hand side of assignments.

      libgo: remove old MIPS architecture names
    
    This removes the old names for the 3 main MIPS ABIs: mipso32, mipsn32
    and mipsn64. It also removes the mipso64 ABI which has no equivalent
    architecture name in go. This ABI has been dead for sometime and I doubt
    anyone will miss it.

    This means that the gc tools and gofrontend agree on the architecture names

    • libgo, syscall: fix ptrace implementation on MIPS · a8bc65cd 
          
    On MIPS, the correct structure for PtraceRegs is 'struct pt_regs' which
    is declared in linux/ptrace.h. Previously no PtraceRegs structure was
    created on MIPS because 'struct user_regs_struct' doesn't exist there.
    
    Fallback to using pt_regs when the PtraceRegs structure is generated in
    mksysinfo.sh, then adjust syscall_linux_mipsx.go to read the program
    counter from the correct field.
    
    In addition, implement PtraceGetRegs and PtraceSetRegs on all 3 ABI
    variants.
    
    syscall_linux_mips64x.go can now be removed since the ptrace code on

    • DWARF: make it possible to emit debug info for declarations only · ff9baa5f 
      The DWARF back-end used to systematically ignore file-scope function and
variable declarations.  While this is justified in language like C/C++,
where such declarations can appear in several translation units and thus
bloat uselessly the debug info, this behavior is counter-productive in
languages with a well-defined module system.  Specifically, it prevents
the description of imported entities, that belong to foreign languages,
making them unavailable from debuggers.

Take for instance:

    package C_Binding is
        function My_C_Function (I : Integer) return Integer;
        pragma Import (C, My_C_Function, "my_c_function");
    end C_Binding;

This makes available for Ada programs the C function "my_c_function"
under the following name: C_Binding.My_C_Function.  When GCC compiles
it, though, it is represented as a FUNCTION_DECL node with DECL_EXTERNAL
set and a null DECL_INITIAL, which used to be discarded unconditionally
in the DWARF back-end.

This patch moves such filter from the DWARF back-end to the relevant
callers: passes.c:rest_of_decl_compilation and
godump.c:go_early_global_decl. It also This patch also updates the Ada
front-end to call debug hooks for functions such as in the above
example, so that we do generate debugging information for them.

	* dwarf2out.c (gen_decl_die): Remove the guard to skip file-scope
	FUNCTION_DECL declarations.
	(dwarf2out_early_global_decl): Remove the guard to skip FUNCTION_DECL
	declarations.
	(dwaf2out_decl): Likewise.
	* godump.c (go_early_global_decl): Skip call to the real debug hook
	for FUNCTION_DECL declarations.
	* passes.c (rest_of_decl_compilation): Skip call to the
	early_global_decl debug hook for FUNCTION_DECL declarations, unless
	-fdump-go-spec is passed.

	* gcc-interface/ada-tree.h (DECL_FUNCTION_IS_DEF): Update copyright
	notice.  New macro.
