ld.bfd's internal linker script considers .text.hot AND .text.hot.* to be part of .text, as well as .text.unlikely and .text.unlikely.*. ld.lld will produce .text.hot.*/.text.unlikely.* sections. Make sure to group these together. Otherwise these orphan sections may be placed outside of the the _stext/_etext boundaries.
