Add VEX support for the s390x "compare and signal" instructions KEBR,
KDBR, KXBR, KEB, and KDB. For now, let them behave exactly like their
non-signalling counterparts. Enhance the bfp-4 test case to cover these
instructions as well. Update the list of supported instructions in
s390-opcodes.csv. Add a disclaimer to README.s390, explaining that FP
signalling is not handled accurately on s390x at the moment.
Add IBM z14 and IBM z14 ZR1 to the list of known machine models. Add an
expected output variant for z14 to the s390x-specific "ecag" test case.
In README.s390, refer to a current version of the z/Architecture
Principles of Operation that describes the instructions introduced with
IBM z14.
Add test cases for the z13 vector FP support. Bring s390-opcodes.csv
up-to-date, reflecting that the z13 vector instructions are now supported.
Also remove the non-support disclaimer for the vector facility from
README.s390.
The patch was contributed by Vadim Barkov, with some clean-up and minor
adjustments by Andreas Arnez.
that the prerequisites for lock elision are met. Then it may use TBEGIN
and other transactional-execution instructions which are not implemented
by Valgrind. Likewise, the upcoming glibc 2.23 will exploit vector
instructions if they are advertised by HWCAP; and those are currently
not implemented by Valgrind either. In general, the increased use of
ifunc may lead to more such cases in the future.
This patch suppresses the advertising of those hardware features via
HWCAP which are either not known to Valgrind or currently unsupported.
