git-svn-id: svn://svn.valgrind.org/valgrind/trunk@15838
The test none/tests/ppc64/test_isa_2_07.c steps beyond the data array in a
number of places. The issue is the array is declared to be of size N. The for
loop is: for (i=0; i<N; i=i+2). In the body of the loop the array elements
A[i] and A[i+1] are accessed. On the last iteration i=N-1 and the second array
access becomes A[N-1+1] which accesses one element past the declared array
size.
This commit fixes the array bounds by making the for loop read:
for (i=0; i<N-1; i=i+2)
The expected output files

The new script (tests/check_ppc64_auxv_cap) in the first patch was

sh maps to bash on a lot of systems but on some it maps to dash. The
script is not compatible with dash.
In retesting the second patch with a fresh svn pull, I found that I
forgot to do the svn add for the new script file. Which causes the
regression test to fail with the second patch applied.
So, I have decided it will be best to just back out patch 1 and 2 for now.

The test case for the transaction memory instructions executes the
failure path when run under valgrind. This is since the initial
Transaction Memory implemnetation is to simply fail the TBEGIN instruction
forcing the execution flow to take the failure path. When the
test case is executed on the real hardware, the success path will
be taken. Only the TBEGIN instruction actually does anything. All other
transactional memory instructions are NOPs since only failure path is executed
and it assumed to not have any transactional memory instructions on it.

When you only specify -many (and not one of -mpower4, -mpower5, etc.),
the assembler/disassembler will choose a default -m<CPU> value for
you. That has changed over time, but is generally one of the newer
server cpus. For example, for binutils trunk, the default is now
-mpower8 and for your 2.23.x binutils, it is -mpower7.
That should force the assembler and disassembler to assemble
the instruction using the server operand order you want, but the bug
above (which is in 2.23) basically resets it to an old cpu, so it
chooses to use the embedded/old cpu setting.
The patch from Amodra fixes the issue by manually generating the correct
hex value for the instruction rather then leaving it to the assembler to
generate the hex value from the symbolic assembly instruction name.
This is the fix for Bugzilla 324765.

behavior of the xscvspdp instruction, indicating that if the source argument
is a SNaN, it is first changed to a QNaN before being converted from
single-precision to double-precision. This updated information about the
xscvspdp instruction exposed a bug in the VEX implementation for that
instruction and also a bug in the testing for all instructions having
special behavior for single-precision SNaN arguments.
The VEX code fix for this issue is r2760.
This patch fixes the test cases for the ISA 2.07.
Testing bug: In several ppc[64] test cases, an array of special
double-precision floating point values is set up, and then all elements of
that array are copied via assignment to a single-precision array ('float'
type). Assignment from a double to a float works fine for all cases, except for
SNaN values. In the case of a SNaN, the source is changed to a QNaN and then
converted to single-precision. So the end result was that our array of floats
did not have an actual SNaN value, and, therefore, any instructions that had
special behavior for a single-precision SNaN input argument was never being
properly tested. This patch makes some functional changes in the following
testcases:
none/tests/ppc[32|64]/test_isa_2_06_part2.c
none/tests/ppc[32|64]/test_isa_2_06_part3.c
none/tests/ppc[32|64]/test_isa_2_07_part2.c
These changes impacted the associated *.stdout.exp files, so the patch also
updates those files. Additionally, there were several errors in testcase
source comments that misidentified QNaN and SNaN bit patterns which this patch
corrects.

The IBM Power ISA 2.07 has been published on power.org, and IBM's new POWER8
processor is under development to implement that ISA. This patch provides
initial runtime and testsuite support for running Valgrind on POWER8 systems
running a soon-to-be released Linux distribution. This Linux distro will
include a POWER8-tuned libc that uses a subset of the new instructions from
ISA 2.07. Since virtually all applications link with libc, it would be
impossible to run an application under Valgrind on this distro without adding
support for these new instructions to Valgrind, so that's the intent of this
patch. Note that applications built on this distro will *not* employ new POWER8
instructions by default. There are roughly 150 new instructions in the Power
ISA 2.07, including hardware transaction management (HTM). Support for these
new instructions (modulo the subset included in this bug) will be added to
Valgrind in a phased approach, similar to what we did for Power ISA 2.06.
