------------------------------------------------------------------------ r360442 | maskray | 2019-05-10 10:09:25 -0700 (Fri, 10 May 2019) | 12 lines [MC][ELF] Copy top 3 bits of st_other to .symver aliases On PowerPC64 ELFv2 ABI, the top 3 bits of st_other encode the local entry offset. A versioned symbol alias created by .symver should copy the bits from the source symbol. This partly fixes PR41048. A full fix needs tracking of .set assignments and updating st_other fields when finish() is called, see D56586.
