Please note that:
(define_insn "*pushtf"
[(set (match_operand:TF 0 "push_operand" "=<,<")
(match_operand:TF 1 "general_no_elim_operand" "x,*roF"))]
"TARGET_64BIT || TARGET_SSE"
{
/* This insn should be already split before reg-stack. */
gcc_unreachable ();
}
[(set_attr "isa" "*,x64")
(set_attr "type" "multi")
(set_attr "unit" "sse,*")
(set_attr "mode" "TF,DI")])
in effect looks like:
(define_insn "*pushtf"
[(set (match_operand:TF 0 "push_operand" "=<")
(match_operand:TF 1 "general_no_elim_operand" "x"))]
on 32bit x86, due to "isa" attribute.

No, only with a crosscompiler to x86_64-apple-darwin11. The i686-linux looks
OK.

The difference si that the call to f128_p3 does not expand with "use (reg:SI
bx)" tag in the Darwin case. Probably ix86_expand_call should be fixed for
TARGET_MACHO.
However, even if this will solve bootstrap, the RA should be fixed to mark PIC
register live in case when constant is moved to memory.

Bug ID: 63652
Summary: [AArch64_be] vzip/vuzp tests fail
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: clyon at gcc dot gnu.org
The vzip/vuzp tests from gcc.target/aarch64/advsimd-intrinsics fail at
execution when the target is aarch64_be.
I am using aarch64_be-none-elf with the Foundation Model as execution engine,
so it could be a bug in that simulator.

Darwin generates indirect access throw generated section: .symbol_stub.
They don't use EBX in the call even without any changes (relaxing EBX usage).

I guess that the mentioned "use" in the call is what keeps PIC register live
accross push in the non-Darwin case.

Further testing indicates that 'cdecl' is okay and that keeping 'regparm(0)'
causes the error.

Not sure I understand Darwin features correct, but they push shifted esp to
calls:
(objdump of example for PR63618)
00000d20 <_f128_square>:
d20: 56 push %esi

Anyway, if call is not EBX dependent (say local call in Linux) the issue is not
reproduced (like in example from PR63618).
So the issue looks like Darwin dependent RA issue.

True. In Darwin case, RA allocates %eax, which is call-used register and
clobbered by the call to f128_p3. I don't see %eax saved around the call.
In Linux case, RA allocates %edi, which is call-saved.

Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++

The under code has two unused variables, which are references to classes. We
should have two warnings, however 4.9.1 and 5.0 trunk gives just one. 4.7.2 and
4.8.3 are ok. The second warning is supressed by the virtual dtor in Bar. Only
the dtor does the trick, if I comment it out or instead I define a plain
virtual fn, the warning appears.

Alternatively, you can just make sure you don't set MACOSX_DEPLOYMENT_TARGET in
your shell.
Also mote that gmp, mpfr and mpc also suffer from this bug and, if built on
10.10, should either have their configure scripts patched or regenerated with
the fixed libtool.

--- Comment #14 from Jeffrey A. Law <law at redhat dot com> ---
Ilya, thanks for the Linux (well, non-Darwin) testcase. I think it shows very
clearly that this is an IRA/LRA problem.
If we look at the .ira dump we have:
(insn/f 43 7 2 2 (parallel [
(set (reg:SI 88)
(unspec:SI [
(const_int 0 [0])
] UNSPEC_SET_GOT))
(clobber (reg:CC 17 flags))
]) 679 {set_got}
(expr_list:REG_UNUSED (reg:SI 88)
(expr_list:REG_UNUSED (reg:CC 17 flags)
(expr_list:REG_EQUIV (unspec:SI [
(const_int 0 [0])
] UNSPEC_SET_GOT)
(expr_list:REG_CFA_FLUSH_QUEUE (nil)
(nil))))))
We assign r88 to %eax. Note the REG_UNUSED note. The validity of the
REG_UNUSED note is debatable since there aren't any uses of r88 in the RTL, but
we do have those "hidden uses" when we have reloads.
Later in the .ira dump we have:
(call_insn 13 12 14 2 (parallel [
(call (mem:QI (reg/v/f:SI 4 si [orig:87 f ] [87]) [0 *(__float128
(*<T311>) (__float128)) f_4(D) S1 A8])
(const_int 32 [0x20]))
(set (reg/f:SI 7 sp)
(plus:SI (reg/f:SI 7 sp)
(const_int 4 [0x4])))
]) j.c:11 657 {*call_pop}
(expr_list:REG_CALL_DECL (nil)
(expr_list:REG_ARGS_SIZE (const_int 28 [0x1c])
(nil)))
(nil))
[ ... ]
(insn 21 18 22 3 (set (mem:TF (pre_dec:SI (reg/f:SI 7 sp)) [1 S16 A128])
(const_double:TF 1.0e+29 [0x0.a18f07d736b90be55p+97])) j.c:13 121
{*pushtf}
(expr_list:REG_ARGS_SIZE (const_int 16 [0x10])
(nil)))
So IRA assigns r88 to %eax. Which makes sense given the raw RTL. As far as
IRA can tell, r88 is just set in the SET_GOT insn and it never gets used.
LRA turns that into:
(insn/f 43 7 2 2 (parallel [
(set (reg:SI 0 ax [88])
(unspec:SI [
(const_int 0 [0])
] UNSPEC_SET_GOT))
(clobber (reg:CC 17 flags))
]) 679 {set_got}
(expr_list:REG_EQUIV (unspec:SI [
(const_int 0 [0])
] UNSPEC_SET_GOT)
(expr_list:REG_CFA_FLUSH_QUEUE (nil)
(nil))))
[ ... ]
(call_insn 13 12 14 2 (parallel [
(call (mem:QI (reg/v/f:SI 4 si [orig:87 f ] [87]) [0 *(__float128
(*<T311>) (__float128)) f_4(D) S1 A8])
(const_int 32 [0x20]))
(set (reg/f:SI 7 sp)
(plus:SI (reg/f:SI 7 sp)
(const_int 4 [0x4])))
]) j.c:11 657 {*call_pop}
(expr_list:REG_CALL_DECL (nil)
(expr_list:REG_ARGS_SIZE (const_int 28 [0x1c])
(nil)))
(nil))
[ ... ]
(insn 46 18 47 3 (set (reg:SI 0 ax [93])
(plus:SI (reg:SI 0 ax [88])
(const:SI (unspec:SI [
(symbol_ref/u:SI ("*.LC0") [flags 0x2])
] UNSPEC_GOTOFF)))) j.c:13 213 {*leasi}
(expr_list:REG_EQUAL (symbol_ref/u:SI ("*.LC0") [flags 0x2])
(nil)))
(insn 47 46 21 3 (set (reg:TF 23 xmm2 [94])
(mem/u/c:TF (reg:SI 0 ax [93]) [1 S16 A128])) j.c:13 126
{*movtf_internal}
(nil))
Which is obviously bogus because %eax is clobbered at insn 13 and thus won't
have a useful value at insn 46.

I checked the testcase. The problem is in absense of pic pseudo 88 in live
in set of BB3 where the constant is put into memory and we need the pseudo to
address it.
Actually, this is LRA design problem. LRA is not designed for
transformations which needs to update global info (live info). That is why it
is called local. LRA as older reload pass uses BB-live info got from
DF-infrastructure right before its work and never uses DF-infrastructure after
that (as reload pass). It can change live info inside BB (reg notes) but never
change live info at BB borders (more correctly it can do this in EBB scope used
to improve inheritance). The reason for this is that changes in RTL are so
massive during LRA/reload that using DF-infrastructure (which has a lot of
on-side data and any RTL change results in changing the data) slows down
compiler a lot (the very first version of LRA was based on DF and it slowed
down the whole compiler by 10%).
The problem could have been solved if we used another alternative which does
need pic pseudos after the transformation. And my additional patches to this
optimization code use this solution (e.g. preventing usage memory equivalence
requiring pic addressing or avoiding putting the constant into memory). But it
can not work in this case as there are not such acceptable altrenatives.
So there are the following solutions of the PR:
o marking pic pseudo lives everywhere but it basically rejects all this
optimization -- unacceptable
o switching to DF-infrastructure. It is a big work and the most important
slows down compiler by about 10% -- unacceptable
o recalculating global live-info without DF (using only DF data-flow
solver)
I see the last as the only solution. Such solution would open a door to
global LRA transformations. It could help for LRA-remat pass too where I am
currently trying to solve some existing performance problems in local scope
only.
I am starting to work on this. I have very few time before the end of the
current stage and it makes me reconsider my current work on LRA-remat pass too.
But I guess I can manage.

Meanwhile, I guess it is obvious that the pic optimization should be switched
off.

So would it work (and I realize this is a horrid hack) to have a way for the
backend to set the pic-pseudo as live at the key points during IRA? It'll be
overly conservative, but it may still be better than going back to a fixed PIC
register. If we had the conservative live information during IRA, presumably
it would flow through to LRA and avoid this problem?

I believe it will disable the optimization completely too. It is up to Intel

The above patch solves all but corner problems, but generates non-optimal push
sequences for constants when general registers are available.
So, we can refer to the above hacky patch to "fix" current bootstrap problems.
This way it is possible to survive a couple of weeks, until the real fix is
available.

--- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Francois, the bug is in _Reuse_or_alloc_node::_M_extract which returns a node
that has a child. When we reuse the node the child is lost.
The LHS of the assignment looks like this:
(gdb) p this->_M_impl._M_header
$1 = {_M_color = std::_S_red, _M_parent = 0x605010, _M_left = 0x605040,
_M_right = 0x605010}
(gdb) p *$1._M_left
$2 = {_M_color = std::_S_red, _M_parent = 0x605010, _M_left = 0x0, _M_right 0x0}
(gdb) p *$1._M_right
$3 = {_M_color = std::_S_black, _M_parent = 0x7fffffffd668, _M_left = 0x605040,
_M_right = 0x0}
When that gets handed to the _Reuse_or_alloc_node
this->_M_impl._M_header._M_right->_M_parent gets set to null, so when
_M_extract returns 0x605010 it thinks it has no more nodes to reuse.

No, I was in fact tempted to commit this patch as a temporary workaround.

> Perhaps put that condition in a function which makes it clear that this is
> just a workaround to give Vlad time to build out the real solution?
Every condition is slightly different, I think that marking the patterns with a
XXX comment, referring to this PR, should be enough.
