--- Comment #8 from Robin Dapp <rdapp at gcc dot gnu.org> --- Created attachment 58037 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=58037&action=edit Expand dump Dump attached. Insn 209 is the problematic one. The changing from _911 to 1078 happens in internal-fn.cc:expand_call_mem_ref (and not via TER). The lookup there is simple and I was also wondering if there is some single_imm_use or so missing.
