[PATCH] vmlinux.lds: consider .text.{hot|unlikely}.* part of .text too

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
