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.

@deftypefn Supplemental double strtod (const char *@var{string}, @

This ISO C function converts the initial portion of @var{string} to a
|
|
@code{double}. If @var{endptr} is not @code{NULL}, a pointer to the
|
|
character after the last character used in the conversion is stored in

the location referenced by @var{endptr}. If no conversion is
|
|
performed, zero is returned and the value of @var{string} is stored in
|
|
the location referenced by @var{endptr}.
