! // See 4827828 for this change. There is no globals_core_i486.hpp. I can't

! // c1 doesn't have this problem because the fix to 4858033 assures us
! // the the vep is aligned at CodeEntryAlignment whereas c2 only aligns
! // the uep and the vep doesn't get real alignment but just slops on by
! // only assured that the entry instruction meets the 5 byte size requirement.
