s390x: Don't emit "vector or with complement" on z13
|
||||
|
||||
The z/Architecture instruction "vector or with complement" (VOC) can be
|
||||
used as an optimization to combine "vector or" with "vector nor". This is
|
||||
exploited in Valgrind since commit 6c1cb1a0128b00858b973e. However, VOC
|
||||
requires the vector-enhancements facility 1, which is not installed on a
|
||||
z13 CPU. Thus Valgrind can now run into SIGILL on z13 when trying to
|
||||
execute vector string instructions.
|
||||
|
||||
Fix this by suppressing the VOC optimization unless the
|
||||
vector-enhancements facility 1 is recognized on the host.
