Not so; relative path works just fine.

The patch was submitted by Will Schmidt (will_schmidt@vnet.ibm.com).
A handful of cosmetic changes to the ppc32 and ppc64 makefiles.
Cleans up some whitespace issues, spaces/tabs/etc,
Rearranges some of the contents so they are logically group, and
more consistent between the 32- and 64- bit versions of the same.

The patch was submitted by Will Schmidt (will_schmidt@vnet.ibm.com).
Update all vgtest files to reference the new capability check helper.
This includes a few adjustments to ensure the test is checking for
the specific capability. I.e. isa_2_07 is a requirement for htm, but
does not indicate htm support is actually present.

The new script (tests/check_ppc64_auxv_cap) in the first patch was
written for the bash shell. I was told by fkrohm that there was an
issue with bash sometime ago and the decision was to use sh instead.
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.
I will fix the script and do this again.

324181 was previously closed with a solution to always make
MAP_32BIT fail. This is technically correct/according to the doc,
but is not very usable.
This patch ensures that MAP_32BIT mmap is succesful, as long as
aspacemgr gives a range in the first 2GB
(so, compared to a native run, MAP_32BIT will fail much more quickly
as aspacemgr does not reserve the address space below 2GB on a 64 bits).
Far to be perfect, but this is better than nothing.
Added a regression test that test succesful mmap 32 bits till
the 2GB limit is reached.

Add a helper script to determine if the platform is ppc64le.
This is specifically used to help exclude the 32-bit tests from being

The VG_(extend_stack) call needs to be properly guarded because the
passed-in address is not necessarily part of an extensible stack
segment. And an extensible stack segment is the only thing that
function should have to deal with.
Previously, the function VG_(am_addr_is_in_extensible_client_stack)
was introduced to guard VG_(extend_stack) but it was not added in all
places it should have been.
Also, extending the client stack during signal delivery (in sigframe-common.c)
was simply calling VG_(extend_stack) hoping it would do the right thing.
But that was not always the case. The new testcase
none/tests/linux/pthread-stack.c exercises this (3.10.1 errors out on it).
Renamed ML_(sf_extend_stack) to ML_(sf_maybe_extend_stack) and add
proper guard logic for VG_(extend_stack).

The objective of libvex_test is to verify that the VEX lib
can be used in 'single arch mode' (host == guest).
The objective of libvexmultiarch_test is to verify that the VEX lib
can be used in 'multi arch mode' (freely choose host and guest).
(but not many combinations are working: if wordsize or endianess
differs, then libVEX quickly asserts somewhere).
libvex_test.c is somewhat bizarre, as it uses the architecture
for which we have compiled as the guest, and use a 'foreign' arch
as the host.
That allows to avoid having to define in the test a bunch
of arch specific asm instructions : the test just decode a part
of its own code, and translate it to other archs.
By default, only the combination host == guest is run.
Arguments must be given to run other combinations.
See libvex_test.c for a description on how to specify which combinations
to run.
LibVEX host != guest does not (yet?) work when endianess or word size differs
between host and guest.
Also, currently, TILEGX host is not working properly (unless guest is also
TILEGX), as the evcheck instructions generated differs according to
the offset of the host_EvC_{FAILADDR,COUNTER}.
So, using TILEGX as host is only done when guest is also TILEGX.
Note that it is possible to specify a specific host arch to use.
For example, to force TILEGX to be used, do:
./none/tests/libvexmultiarch_test 1034
(where 1034 is the decimal value corresponding to the enum VexArchTILEGX.
This currently aborts with:
...
------------------------ Assembly ------------------------
EvCheck (evCheck) ld r11, 8(r50); addli r11, r11, -1; st r11, 8(r50); bgez r11, nofail; jalr *(r50); nofail:
vex: priv/host_tilegx_defs.c:2353 (emit_TILEGXInstr): Assertion `evCheckSzB_TILEGX() == (UChar*)p - (UChar*)p0' failed.
//// failure exit called by libVEX
Whe TILEGX is fixed, we can remove the specific condition that avoids using
TILEGX as host.
Small changes have been done on VEX to allow more combinations
to work:
* host_mips_defs.c : when not compiled on mips,
a lot of mips specific code is not compiled at all, because
one of _MIPSEL or _MIPSEB must be defined to have either the
little endian code or big endian code.
emit32 function must however work to use mips as host.
So, for this function, if _MIPSEL is not defined, then
the big endian code is compiled in by default.
(the mips endianess should probably be handled like the ppc
endianess, for which the endianness to use is decided at runtime).
* host_arm64_isel.c : addition of a 'do not emit anything' for
ABI HINT (avoid an assert e.g. for amd64 guest, arm64 host)
* libvex_guest_amd64.h : when I was still hoping mixing amd64 and x86,
a first assert was firing up due to size/alignment
of VexGuestAMD64State when compiled in 32 bits.
=> addition of pad elements to ensure the size and alignment
of VexGuestAMD64State stays the same when compiled in 32 and
64 bits (the 64 bits layout is unchanged).
The new tests have been run on x86/amd64/ppc64/s390x.
It is very well possible that the tests will fail on untested archs
(ppc32 or mips* or arm* or tilegx)
(e.g. because the hardcoded hwcaps in libvex_test.c are not ok).
It should be relatively trivial to fix these hwcaps problems.
Some other problems might be less easy to understand and fix
(e.g. similar to the TILEGX evcheck or mips emit32 problem).
