[kvm-unit-tests PATCH] s390x: Align __bss_end to a halfword boundary

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

 



We are using the "larl" instruction to load the address of __bss_end,
and this instruction can only deal with even addresses, so we have
to make sure that this symbol is aligned accordingly. Otherwise this
will cause a failure with the new binutils 2.40 and Clang:

 /usr/bin/ld: s390x/cstart64.o(.init+0x6a): misaligned symbol `__bss_end'
              (0x2c0d1) for relocation R_390_PC32DBL
