[PATCH] testsuite tcl portability fix - avoid lreverse
Hi!
I've noticed
ERROR: (DejaGnu) proc lreverse {{ASAN_OPTIONS 0}} does not exist.
errors when regtesting gcc 4.8 on RHEL 5, it seems lreverse has been added
to tcl only in version 8.5.
Fixed thusly, ok for trunk?

Does that help? Perhaps the M-N feature isn't supported by your version
of tcl.
* lib/target-supports-dg.exp (dg-process-target): Use expr to
evaluate the end index in string range.
Yes, this seems to help for tcl 8.4.13 and works also with 8.5.11 (where it
worked before too).
So, ok for trunk, thanks.

[PATCH][ARM] use vsel instruction for floating point conditional moves in ARMv8
Hi all,
This patch uses the new ARMv8 AArch32 vsel instruction to implement
conditional moves of floating point numbers.
For example, an instruction of the form:
vselcond.f32 s0, s1, s2
means
s0 := cond ? s1 : s2
This can be useful, among other places, in Thumb2 because it doesn't require
an enclosing IT block.
A small catch: The condition code used in vsel can only be one of {GE, GT,
EQ, VS}. If we want to use their negations {LT, LE, NE, VC} we just flip the
source operands.
A new predicate is introduced that checks that the comparison yields an ARM
condition code in the set {GE, GT, EQ, VS, LT, LE, NE, VC}.
New compilation tests are added. They pass on a model and no new regressions
on arm-none-eabi with qemu.
Ok for trunk?
Thanks,
Kyrill

Re: [PATCH] Vtable pointer verification (corruption/attach detection -- new feature
On 11/01/2012 09:07 PM, Caroline Tice wrote: We have been developing a new security hardening feature for GCC that is designed to detect and handle (during program execution) when a vtable pointer that is about to be used for a virtual function call is not a valid vtable pointer for that call (i.e. it has become corrupted, possibly due to a hacker attack). We gave a presentation on this work at the Gnu Tools Cauldron in Prague last July. We now have the implementation fully working and are submitting this patch for review. We would like to get this into the next release of GCC if possible. Thanks for posting this collection of interesting patches. As far as I understand it, this changes ABI in the sense that every object file needs to contain the constructors that register the vtables, otherwise verification will later fail. If this data could be emitted in a declarative fashion, it might be possible to emit it by default, in a separate ELF section. This way, it is always there when needed, and it wouldn't have any performance impact if not used. I didn't look at the actual permitted-vtable set lookup in detail. How expensive is it? C++ virtual method calls are efficient, but they have their problems. The vtable needs relocation (contributing to startup cost), and we have the fragile base class problem (which severely constrains the evolution of separately-compiled base classes). Assuming that we need the vtable check and it has non-trivial cost, it might make sense to revamp C++ virtual method dispatch altogether, addressing both security and modularity issues. (Yes, I understand these two paragraphs go off in entirely different directions. 8-) -- Florian Weimer / Red Hat Product Security Team

Hmm, that worked with my release-checking compiler of course, but
fails in at least tree-ssa-dom.c (same as for fwprop.c,
loop_optimizer_init destroys fast queries) and tree-ssa-loop-im.c (not
sure yet why).
NB, the fwprop.c change is independent and should go in. The domwalk.c
thing is something to maybe postpone to gcc 4.9.
The fwprop.c change is ok - fwprop.c doesn't seem to care about
identified latches or preheaders.
Now, I wonder what part of loop_optimizer_init wrecks dominance
info - I _suppose_ it's disambiguate_loops_with_multiple_latches (),
but that only ends up calling make_forwarder_block which looks like
it has code to fix dominators via iterate_fix_dominators ().
Hmm, it seems to be
make_forwarder_block (basic_block bb, bool (*redirect_edge_p) (edge),
void (*new_bb_cbk) (basic_block))
{
...
fallthru = split_block_after_labels (bb);
that sets DOM_NO_FAST_QUERY via add_to_dominance_info () via
create_basic_block. Then split_block () does
482 if (dom_info_available_p (CDI_DOMINATORS))
483 {
484 redirect_immediate_dominators (CDI_DOMINATORS, bb, new_bb);
485 set_immediate_dominator (CDI_DOMINATORS, new_bb, bb);

but that doesn't set dominance info to DOM_OK again. The
iterate_fix_dominators doesn't do that either.
IMHO at least split_block () should be able to preserve fast queries?

[PATCH] Speed up IDF compute a tiny bit
While looking into speeding up incremental SSA update for PR56113
(it's IDF compute slowness) I played with optimizing IDF compute
itself. One obvious thing that speeds it up by 5% is to use
quick_push in the innermost loop. When experimenting with using
a sparseset for the worklist to avoid iterating multiple times
I noticed its workers have embedded gcc_assert()s which prevents
them from being inlined. Thus, fixed as well.
Bootstrap and regtest running on x86_64-unknown-linux-gnu.
As for the IDF slowness - I suppose a different PHI insertion
strategy that is not quadratic would be nice.

but that doesn't set dominance info to DOM_OK again. The
iterate_fix_dominators doesn't do that either.
IMHO at least split_block () should be able to preserve fast queries?
I don't see how. Fast queries rely on DFS in and out numbers of the
dominance tree being correct. If you insert a node in a tree the
DFS numbers of all nodes after it need to change, i.e. updating fast
queries for a single-block change is O(n_basic_blocks).

libasan has added recently support for operator new and operator new[]
checking, which checks that there is not a mismatch between the way
how object is allocated (malloc/calloc/realloc vs. operator new vs. operator
new[]) and how it is deallocated (free vs. delete vs. delete[]). The
deep-stack-uaf-1.C testcase has been violating this (new char[10]
allocation, free (x) deallocation) and has been changed upstream
when those changes landed into libasan. When -lstdc++ came first,
the -lasan operator new interceptor wasn't called (because libstdc++'s
operator new was earlier in search scope) and thus it appeared as calling
malloc and doing free to -lasan.

[PATCH][ARM][1/2] Load-acquire, store-release atomics in AArch32 ARMv8
Hi all,
This patch implements the atomic built-ins using the new ARMv8 load-acquire
and store-release instructions.
They allow us to generate barrier-free code for a variety of atomic
operations such as: atomic load, atomic store, atomic compare and swap,
atomic {or, and, add, sub, xor}.
Tests will come in a separate patch soon.
No regressions on arm-none-eabi. Bootstrap on armv7l-unknown-linux-gnueabihf
successful.
Ok for trunk (now or when stage 1 reopens)?
Thanks,
Kyrill

In register_vptr_fields it seems that given a base B and derived D, you
are adding all the elements of D's VTT to the list of valid vtables for
a B, but this isn't correct; elements of D's VTT may be vtables for

[4.8.[01]] PowerPC di-ti widening multiplication
For gcc 4.9, I intend to ensure that optabs.c can make automatic use of
[us]mulmode_highpart. There are plenty of targets that only implement
_highpart but not the widening pattern. But that's not something that
would be appropriate at this stage in the 4.8 cycle.
Whether this patch is appropriate for 4.8.0 is someone else's call, but
it's probably safe to queue it for 4.8.1.

[PATCH] GCC 4.9 powerpc, merge SF/SD moves
This is a series of patches taken from my power8 work meant for inclusion against GCC 4.9 when 4.8 is branched, and stage1 of 4.9 opens up again. They could be installed in 4.8 at the discretion of David. This patch merges together the movsd/movsf patterns, so that when I make changes to the basic move patterns, I don't have to remember to do the same work in two places. Along with combining the moves, I added support to use the LFIWZX (power7) and STFIWX (power6) instructions to store SDmode variables directly. Before this, we needed to create a wider buffer on the stack, and move the values from a register to the buffer, and use a wider load on the floating point side to load them up. Now under power7, it no longer uses this buffer. A minor other change is that now the compiler will use the VSX XXLXOR instruction to clear a single precision floating point value, instead of loading the zero value from memory. I have bootstraped, and there are no regressions with these patches. Are these patches acceptible, so that I can check them in directly when the GCC 4.9 tree opens up?

In the attached patch, I let SLP recognize vector loads/stores just like it recognizes those in an array. It has a few issues: the cost of the vectorized version is overestimated, the base object is wrong (doesn't strip the bit_field_ref, but since the base address is right and the base object is almost unused...), but most importantly it only works if the vectors have their address taken, otherwise (after asking gimple_vuse?) SLP doesn't detect their use as loads or stores at all. Yes, if they have not their address taken they are not loads. Also, it only works if you write result[0]=..., result[1]=... and does not recognize a constructor as a series of stores. Is slowly extending SLP the right way to go? Should get_references_in_stmt report vector element accesses? It does if it is a memory access. You didn't provide a new testcase so it's hard for me to guess what you are trying to do. I suppose you want to vectorize w[0] = v[0] + v[0]; w[1] = v[1] + v[1]; into w = v + v; As it would work if w and v are array accesses instead of vector subscripts? Yes, sorry for not being more precise. Vectorization that works for an array should work (even better) for a vector. Note that similar issues (and bugreports) exist for complex component accesses. One extension at a time :-) As of handling non-memory BIT_FIELD_REFs - I suggest to split out the test of whether a stmt is considered a load for the purpose of vectorization and simply special-case this therein, not requiring a VUSE. Ok. The hardest part will be preventing the pass from creating ADDR_EXPR of those vectors, or at least folding them before the pass is done. I suppose the data-ref analysis parts are not strictly required, nor the get_addr_base_and_unit_offset_1 parts? Actually it is necessary (at least the get_addr_base_and_unit_offset_1 part is) otherwise I get a gimple verification failure because we have an ADDR_EXPR of a BIT_FIELD_REF. They should be split out and separately tested anyway. The data-ref part at least will confuse analysis of 'a[0]' or 'a[1]' vs. 'a', but I suppose independent of the patch. Ah... Could you be more specific? Are you thinking about arrays of vectors? Thanks for the help, -- Marc Glisse

the -mmfpgpr code with the normal floating point moves, using a new conditional
constraint (wg) that only returns FLOAT_REGS for the power6x.
I have tested this via bootstrap, and there were no regressions. Is patch
acceptable to check in when the 4.9 tree opens up?

libgo patch committed: Better backtraces
This patch to libgo fixes backtrace information when optimizing.
Previously the backtraces just collected PC values and then converted
them into file/line information. This of course works poorly when
functions are inlined. This version uses the facilities of libbacktrace
to get good backtraces in the presence of inlined functions. It also
skips the split-stack functions, which are not of interest when getting
a Go backtrace. Bootstrapped and ran Go testsuite on
x86_64-unknown-linux-gnu. Committed to mainline.

[PATCH] PowerPC merge TD/TF moves
This patch like the previous 2 pages combines the decimal and binary floating
point moves, this time for 128-bit floating point.
In doing this patch, I discovered that I left out the code in the previous
patch to enable the wg constraint to enable -mcpu=power6x to utilize the direct
move instructions. So, I added the code in this patch, and also created a test
to make sure that direct moves are generated in the future.
I also added the reload helper for DDmode to rs6000_vector_reload that was
missed in the last patch. This was harmless, since that is only used with an
undocumented debug switch. Hopefully sometime in the future, I will scalar
floating point to be able to be loaded in the upper 32 VSX registers that are
overlaid over the Altivec registers.
Like the previous 2 patches, I've bootstrapped this, and ran make check with no
regressions. Is it ok to apply when GCC 4.9 opens up?
I have one more patch in the insn combination to post, combining movdi on
systems with normal floating point and with the power6 direct move
instructions.
