/* Like vsprintf but provides a pointer to malloc'd storage, which must
be freed by the caller.
Update the libiberty sources with the latest patches found in the master sources. 2017-01-02 Richard Biener <rguenther@suse.de> PR lto/83452 * simple-object-elf.c (simple_object_elf_copy_lto_debug_section): Do not use UNDEF locals for removed symbols but instead just define them in the first prevailing section and with no name. Use the same gnu_lto_v1 name for all removed globals we promote to WEAK UNDEFs so hpux can use a stub to provide this symbol. Clear sh_info and sh_link in removed sections. 2017-10-30 Richard Biener <rguenther@suse.de> PR lto/82757 * simple-object-elf.c (simple_object_elf_copy_lto_debug_sections): Strip two leading _s from the __gnu_lto_* symbols. 2017-10-24 Alan Modra <amodra@gmail.com> PR lto/82687 PR lto/82575 * simple-object-elf.c (simple_object_elf_copy_lto_debug_sections): Only make __gnu_lto symbols hidden. 2017-10-20 Alan Modra <amodra@gmail.com> PR lto/82575 * simple-object-elf.c (simple_object_elf_copy_lto_debug_sections): Make discarded non-local symbols weak and hidden. 2017-10-18 Jakub Jelinek <jakub@redhat.com> PR lto/82598 * simple-object.c (handle_lto_debug_sections): Copy over also .note.GNU-stack section with unchanged name. * simple-object-elf.c (SHF_EXECINSTR): Define. (simple_object_elf_copy_lto_debug_section): Drop SHF_EXECINSTR bit on .note.GNU-stack section. 2017-09-25 Nathan Sidwell <nathan@acm.org> PR demangler/82195 * cp-demangle.c (d_encoding): Strip return type when name is a LOCAL_NAME. (d_local_name): Strip return type of enclosing TYPED_NAME. * testsuite/demangle-expected: Add and adjust tests. 2017-09-21 Nathan Sidwell <nathan@acm.org> PR demangler/82195 * cp-demangle.c (d_name): Revert addition of 'toplevel' parm. (has_return_type): Recurse for DEMANGLE_COMPONENT_LOCAL_NAME. (d_encoding): Revert d_name change. Use is_fnqual_component_type to strip modifiers that do not belong. (d_special_name, d_class_enum_type): Revert d_name call change. (d_expresion_1): Commonize DEMANGLE_COMPONENT_UNARY building. (d_local_name): Revert parsing of a function type.

Like @code{vsprintf}, but instead of passing a pointer to a buffer,
you pass a pointer to a pointer. This function will compute the size
of the buffer needed, allocate memory with @code{malloc}, and store a
pointer to the allocated memory in @code{*@var{resptr}}. The value
returned is the same as @code{vsprintf} would return. If memory could
not be allocated, minus one is returned and @code{NULL} is stored in
