    gdbserver: Suffix generated C files with -generated
    
    I noticed that there were some missing files in gdbserver's gitignore
    (some generated register format .c files).  Of course the easy fix would
    be to add those files to .gitignore, but I think we can do a better job,
    so that we don't have to worry about adding generated files to
    .gitignore or the clean Makefile target.
    
    I suggest naming all generated source files -generated.c.  This way, we
    can use a single rule in .gitignore and do a "rm -f *-generated.c" to
    clean them up.
    
    New in v2:
    
      - Don't rename version.o and xml-builtin.o
    
    gdb/gdbserver/ChangeLog:
    
    	* .gitignore: Remove generated files, replace with wildcard.
    	* (clean): Replace removal of generated files with wildcard.
    	(version.c): Replace with...
    	(version-generated.c): ...this.
    	(xml-builtin.c): Replace with...
    	(xml-builtin-generated.c): ...this.
    	(%-ipa.o: %-generated.c, %.o: %-generated.c): New rules.
    	(%.c: *regformats*): Replace with...
    	(%-generated.c: *regformats*): ...this.

    Fix classification of `module.type' in D lexer.
    
    The two-tier lexer in gdb/d-exp.y, which resolves fully qualified names
    missed a case where `module.type' was not being classified as one token.
    And so when the grammar takes over, it matched the remaining tokens
    against the rule `TypeExp . IdentifierExp', where we were expecting to
    instead match cast expression `( TypeExp ) UnaryExpression'.
    
    Adding a case for TYPE_CODE_MODULE in type_aggregate_p means that
    classify_inner_name will get a chance to lookup the symbol.
    
    This was noticed when using `watch -l', and got the rather confusing
    response:
    
        A syntax error in expression, near `) 0x0add4e55'.
    
    So it's been included in the testsuite, along with another test that
    does effectively the same expression, but explicitly.
    
    gdb/ChangeLog:
    
    	* d-exp.y (type_aggregate_p): Treat TYPE_CODE_MODULE as being
    	aggregate-like.

    arc: Add disassembler helper
    
    Add disassembler helper for GDB, that uses opcodes structure arc_instruction
    and adds convenience functions to handle instruction operands.  This interface
    solves at least those problems with arc_instruction:
    
      * Some instructions, like "push_s", have implicit operands which are not
        directly present in arc_instruction.
      * Operands of particular meaning, like branch/jump targets, have various
        locations and meaning depending on type of branch/target.
      * Access to operand value is abstracted into a separate function, so callee
        code shouldn't bother if operand value is an immediate value or in a
        register.
    
    Testcases included in this commit are fairly limited - they test exclusively
    branch instructions, something that will be used in software single stepping.
    Most of the other parts of this disassembler helper are tested during prologue
    analysis testing.

    gdb/cp-name-parser.y: Eliminate make_empty, use cplus_demangle_fill_component
    
    The demangler exports the cplus_demangle_fill_component function that
    clients should use to initialize demangle_component components that
    use the "s_binary" union member.  cp-name-parser.y uses it in some
    places, via the fill_comp wrapper, but not all.  Several places
    instead use a GDB-specific "make_empty" function.  Because this
    function does not call any of the demangler "fill" functions, we had
    to patch it recently to clear the allocated demangle_component's
    "d_printing" field, which is supposedly a "private" demangler field.
    To avoid such problems in the future, this commit switches those
    places to use "fill_comp" instead, and eliminates the "make_empty"
    function.

    	* cp-name-parser.y (make_empty): Delete.
    	(demangler_special, nested_name, ptr_operator, array_indicator)
    	(direct_declarator, declarator_1): Use fill_comp instead of
    	make_empty.

    cplus_demangle_fill_component: Handle DEMANGLE_COMPONENT_RVALUE_REFERENCE
    
    This patch almost a decade ago:
    
    ...
        2007-08-31  Douglas Gregor  <doug.gregor@gmail.com>
    
            * cp-demangle.c (d_dump): Handle
            DEMANGLE_COMPONENT_RVALUE_REFERENCE.
            (d_make_comp): Ditto.
    ...
    
    ... missed doing the same change to cplus_demangle_fill_component that
    was done to d_make_comp.  I.e., teach it to only validate that we're
    not passing in a "right" subtree.  GDB has recently (finally) learned
    about rvalue references, and a change to make it use
    cplus_demangle_fill_component more ran into an assertion because of
    this.
    
    (GDB is the only user of cplus_demangle_fill_component in both the gcc
    and binutils-gdb trees.)

    Fix gdb_xml_debug/gdb_xml_error ATTRIBUTE_PRINTF use
    
    The declarations of gdb_xml_debug and gdb_xml_error are passing "0" as
    "first-to-check" argument to ATTRIBUTE_PRINTF, as if they were va_args
    functions.  Consequently, the arguments to gdb_xml_debug /
    gdb_xml_error aren't being checked against the format strings.

    Remove some unnecessary inferior_ptid setting/restoring when fetching/storing registers
    
    Now that the to_fetch_registers, to_store_registers and
    to_prepare_to_store target methods don't rely on the value of
    inferior_ptid anymore, we can remove a bunch of now unnecessary setting
    and restoring of inferior_ptid.
    
    The asserts added recently in target_fetch_registers and
    target_store_registers, which validate that inferior_ptid matches the
    regcache's ptid, must go away.  It's the whole point of this effort, to
    not require inferior_ptid to have a particular value when calling these
    functions.
    
    One thing that I noticed is how sol-thread.c's ps_lgetregs and friends
    use the current value of inferior_ptid instead of what's passed as
    argument (ph->ptid), unlike proc-service.c's versions of the same
    functions.  Is it expected?  I left it like this in the current patch,
    but unless there's a good reason for it to be that way, I guess we
    should make it use the parameter.
    
    gdb/ChangeLog:
    
    	* fbsd-tdep.c (fbsd_corefile_thread): Don't set/restore
    	inferior_ptid.

    	Remove asserts.

    Remove constness of libdir in do_start_initialization
    
    The patch "Fix memory leak in python.c:do_start_initialization"
    (https://sourceware.org/ml/gdb-patches/2017-03/msg00407.html) introduced a
    compilation error on some platforms:
    
      ../../binutils-gdb/gdb/python/python.c: In function bool do_start_initialization():
      ../../binutils-gdb/gdb/python/python.c:1556:16: error: invalid conversion from const void* to void* [-fpermissive]
       xfree (libdir);
                    ^
    
    This is fixed by removing the constness of libdir's data type.
    
    gdb/ChangeLog:
    
    	* python/python.c (do_start_initialization): Remove 'const' from
    	data type of libdir.

    Fix memory leak in python.c:do_start_initialization
    
    When intializing Python the path to the python binary is build the
    following way
    
    progname = concat (ldirname (python_libdir), SLASH_STRING, "bin",
    		   SLASH_STRING, "python", (char *) NULL);
    
    This is problematic as both concat and ldirname allocate memory for the
    string they return.  Thus the memory allocated by ldirname cannot be
    accessed afterwards causing a memory leak.  Fix it by temporarily storing
    libdir in a variable and xfree it after concat.
    
    gdb/ChangeLog:
    	python/python.c (do_start_initialization): Fix memory leak.

    Sanitize RISC-V GAS help text, documentation
    
    It looks like I missed the GAS help text when going through all the
    documentation last time, so it printed some of the old-format (never
    upstream) arguments.  I fixed this, and when I went to check doc/ I
    noticed it was missing the '-fpic'/'-fno-pic' options.

+@section WebAssembly backend
+The WebAssembly module file format, at present, is a very simple
+object file format with up to 11 numbered sections plus named
+``custom'' sections. At present, there is no standard for relocations
+or symbols, though a @code{"name"} subsection can assign names to
+function indices and local variables.
+
+As such, it offers no real advantages over ELF, and intermediate ELF
+files can be used to produce WebAssembly modules. The WebAssembly
+backend aims to enable the opposite: reading a WebAssembly module and
+producing an ELF file containing the same information, which can then
+be manipulated and inspected with standard tools.
+
+When writing WebAssembly modules, the WebAssembly backend attempts to
+determine based on the section name whether to use a numeric section
+id, a named section header, or to include the section verbatim,
+assuming it already contains any necessary header.
+
+Function names are supported as symbols; local names and WebAssembly
+relocation sections are currently unsupported.
+
+There are slight differences in the LEB128 integer implementations
+between the WebAssembly specification and the BFD code; these result
+in some malformed WebAssembly modules being treated as valid.
