Bug ID: 431157
Summary: PPC_FEATURE2_SCV needs to be masked in AT_HWCAP2
Product: valgrind
Version: unspecified
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: vex
Assignee: jsew...@acm.org
Reporter: fwei...@redhat.com

valgrind cannot run glibc binaries with SCV support on current kernels:

AT_HWCAP2 contains the SCV bit even though valgrind does not support the SCV
instruction.
Seen with valgrind-3.16.1-11.fc33.ppc64le.
