Valgrind on s390x currently lacks support for the miscellaneous
instruction extensions facility 2.
Signed-off-by: Ilya Leoshkevich <iii@linux.ibm.com>
Fix false positives when invoking s390-check-opcodes.pl. Also clean up
some code formatting issues in that script. Add the instructions TPEI and
IRBM to guest_s390_toIR.c and s390-opcodes.csv, so they are not longer
warned about.
Sync VEX/LICENSE.GPL with top-level COPYING file. We used 3 different
addresses for writing to the FSF to receive a copy of the GPL. Replace
all different variants with an URL <http://www.gnu.org/licenses/>.
The following files might still have some slightly different (L)GPL
copyright notice because they were derived from other programs:
- files under coregrind/m_demangle which come from libiberty:
cplus-dem.c, d-demangle.c, demangle.h, rust-demangle.c,
safe-ctype.c and safe-ctype.h
- coregrind/m_demangle/dyn-string.[hc] derived from GCC.
- coregrind/m_demangle/ansidecl.h derived from glibc.
- VEX files for FMA detived from glibc:
host_generic_maddf.h and host_generic_maddf.c
- files under coregrin/m_debuginfo derived from LZO:
lzoconf.h, lzodefs.h, minilzo-inl.c and minilzo.h
- files under coregrind/m_gdbserver detived from GDB:
gdb/signals.h, inferiors.c, regcache.c, regcache.h,
regdef.h, remote-utils.c, server.c, server.h, signals.c,
target.c, target.h and utils.c
Plus the following test files:
- none/tests/ppc32/testVMX.c derived from testVMX.
- ppc tests derived from QEMU: jm-insns.c, ppc64_helpers.h
and test_isa_3_0.c
- tests derived from bzip2 (with embedded GPL text in code):
hackedbz2.c, origin5-bz2.c, varinfo6.c
- tests detived from glibc: str_tester.c, pth_atfork1.c
- test detived from GCC libgomp: tc17_sembar.c
- performance tests derived from bzip2 or tinycc (with embedded GPL
text in code): bz2.c, test_input_for_tinycc.c and tinycc.c
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.
This adds test cases and some internal stuff to the z/Architecture vector
integer and string instruction support.

This adds z/Architecture vector integer and string instruction support.
The main author of this patch is Vadim Barkov <vbrkov@gmail.com>. Some
fixes were provided by Andreas Arnez <arnez@linux.ibm.com>.
This implements various z/Architecture instructions that conditionally
yield a data exception ("trap"). The condition is either based on a
comparison being true ("compare and trap") or on a loaded value being
zero ("load and trap"). These instructions haven't been widely used in
the past, but may now be emitted by newer compilers. Note that the
resulting signal for a data exception is SIGFPE, not SIGTRAP. Thus this
patch also adds a new jump kind Ijk_SigFPE.

Valgrind currently lacks support for the z/Architecture vector "support"
instructions introduced with z13. These are documented in the
z/Architecture Principles of Operation, Eleventh Edition (March, 2015),
chapter 21: "Vector Overview and Support Instructions".
