Can you identify these two? Sorry for being dense :-) I could using conditional breakpoints once I had unraveled how to identify the note number from an rtx. Here's what I found: note 374: (note 229 161 230 NOTE_INSN_EPILOGUE_BEG) (code_label 243 324 162 31 "" [1 uses]) .cfi_def_cfa 29, 80 .cfi_offset 16, -72 .cfi_offset 17, -64 .cfi_offset 18, -56 .cfi_offset 19, -48 .cfi_offset 20, -40 .cfi_offset 21, -32 .cfi_offset 22, -24 .cfi_offset 28, -16 .cfi_offset 64, -8 note 375: (note 229 161 230 NOTE_INSN_EPILOGUE_BEG) (code_label 243 324 375 31 "" [1 uses]) .cfi_def_cfa 29, 80 .cfi_offset 16, -72 .cfi_offset 17, -64 .cfi_offset 18, -56 .cfi_offset 19, -48 .cfi_offset 20, -40 .cfi_offset 21, -32 .cfi_offset 22, -24 .cfi_offset 28, -16 .cfi_offset 64, -8 Rainer
