--- Comment #22 from Richard Biener <rguenth at gcc dot gnu.org> ---
There is target specific sanitizing of symbol names - if the name is really=
 the
issue then it should be _much_ more prevalent since all IPA cloning uses
dots as well.  clone_function_name produces them and ASM_FORMAT_PRIVATE_NAME
is the "sanitizer" that's supposed to mangle it to correct form.  But as the
name suggests the definition of a local private symbol isn't supposed to go
away without all of its uses so the real issue must be elsewhere in
optimization.
(thus asking for IPA dumps, specifically the .000i.cgraph dump which should
mention when the compiler thinks the .LTHUNK5.lto_priv.0 goes away)=
