Title:
[UBUNTU 20.10] GCC: Accept vector alignment hints on z13
Status in linux package in Ubuntu:
New
Bug description:
On z13 we have that vector alignment hints are already accepted. This
backport enables GCC to emit such hints not only for target z14 but
also for z13 in case GAS accepts them on z13, too. Since GCC's default
target on Ubuntu is z13 for s390x, we could greatly benefit from such
alignment hints. (note a separate bugzilla entry for binutils/GAS
allowing to accept alignment hints for z13 has been opened)
This is a backport of upstream commits 313e02cfb97 and 710f7d977d1.
