--- Comment #4 from Martin Liška <marxin at gcc dot gnu.org> --- Started with r8-2488-g8e941ae950ddce17 i386: Don't use frame pointer without stack access When there is no stack access, there is no need to use frame pointer even if -fno-omit-frame-pointer is used and caller's frame pointer is unchanged. which seems as a reasonable explanation to not emit stack pointer?
