--- Comment #3 from Teresa Johnson <tejohnson at google dot com> --- Yes, there is a NOTE_INSN_SWITCH_TEXT_SECTIONS note emitted for functions that are split. In the attached test case the symbol-symbol expression is being generated across the split boundary of main(), and I confirmed that the NOTE is there in between the hot/cold sections.
