RH-Commit: [21/23] 17e89c1a3ca01b9de4683aebdbd06c5350422d27 (thuth/qemu-kvm-cs9)
|
|
|
|
The assembler directive .align [1] has architecture-dependent behavior,
|
|
which may be ambiguous for the reader. Some architectures perform the
|
|
alignment in bytes, others in power of two. s390 does in bytes.
|
|
|
|
Use the directive .balign [2] instead, to clarify that the alignment
|
|
request is in bytes. No functional change.
