[Bug tree-optimization/110327] [12/13/14 Regression] Missed Dead Code Elimination when using __builtin_unreachable since r12-4790-g4b3a325f07a

[law at gcc dot gnu.org via Gcc-bugs]

--- Comment #3 from Jeffrey A. Law  ---
Two block copies isn't fatal when the second one is the one with the actual
jump thread.  But costing does get more complex.  

Basically we copy 8 so that we can isolate its two incoming paths which thread
differently in bb10.  That's pretty standard stuff.

It looks like that particular threading possibility is hidden until after DOM3
is complete.  Prior to and during DOM3, there's another block in the way.


  # c.3_16 = PHI <0(3), 2(5)>
  _9 = h;
  _10 = *_9;
  _11 = *_10; 
  _12 = *_11; 
  _13 = (char) _12;
  if (_13 != -28)
goto ; [0.00%]
  else
goto ; [100.00%]
;;succ:   8
;;9

;;   basic block 8, loop depth 0
;;pred:   7
  __builtin_unreachable ();
;;succ:

;;   basic block 9, loop depth 1
;;pred:   7
  if (_12 <= 4)
goto ; [50.00%]
  else
goto ; [50.00%]
;;succ:   10
;;15

;;   basic block 10, loop depth 1
;;pred:   9
  _15 = d;
  *_10 = _15;
  if (c.3_16 <= 0)
goto ; [5.50%]
  else
goto ; [94.50%]

As you note, this feels like a failure to recognize that only one value can
actually satisfy the condition.

So one of the edges in the jump threading path gets removed.  As a result the
threader throws the path away.  At least that's my best guess.

We could possibly defer block merging until after threading.  No idea how hard
that might be.  The sequencing is a bit painful, but IIRC the key is that we
must remove unreachables in the CFG before threading (due to how unreachables
interact with the dominator tree updates).

--- Comment #5 from Jeffrey A. Law  ---
One could also look at this as a failure to propagate.

  l.0_1 = l;
  t_4 = (short int) l.0_1;
  if (t_4 == 0)
goto ; [50.00%]
  else
goto ; [50.00%]


We ought to be able to propagate l.0_1 into the conditional for t_4.  If we do
that, then we'll be able to propagate 0 for l.0_1 in this block:

;;   basic block 3, loop depth 0, count 536870912 (estimated locally, freq
0.5000)
;;prev block 2, next block 4, flags: (NEW, VISITED)
;;pred:   2 [50.0% (guessed)]  count:536870912 (estimated locally, freq
0.5000) (TRUE_VALUE,EXECUTABLE)
  b_5 = (char) l.0_1;
  if (b_5 != 1)
goto ; [0.00%]
  else
goto ; [100.00%]


And once we propagate the value 0 that will make the make bb5 (containing the
call to foo) unreachable.

IIRC we have (had?) some code to do these kinds of propagations through
conversions.  IIRC it was fairly conservative, perhaps overly so.

So like the other bug involving multiplies against objects with a known range
[0,1], we should very seriously consider turning the multiply into a
conditional move.  ie x * b where b is known to have the range [0,1] we can
turn that into

dest = b ? x : 0

Some processors that don't have generalized conditional moves do have
conditional zero instructions.  ie, zicond on RISC-V.

I wouldn't look at with/without tree-sra.  Instead I would look at the assembly
code before/after your change.  It's clearly worse.  testK goes from ~37
instructions to ~70 and the abort call is no longer removed.

[Bug tree-optimization/110293] Some `A CMP (A NEEQ 0)` is not simplified in some cases

[pinskia at gcc dot gnu.org via Gcc-bugs]

--- Comment #10 from Andrew Pinski  ---
Here is some more optimizations where the inner CMP is not EQ/NE:
signed:
x == (x <= CST) -> CST == 0 ? false : CST < 0 ? x == 0 : x == 1
x == (x  < CST) -> CST == 1 ? false : CST <= 0 ? x == 0 : x == 1

unsigned:
x == (x u<= CST) -> CST == 0 ? false : x == 1 (note 0 should already be
handled)
x == (x u<= CST) -> CST == 0 ? x == 0 : CST == 1 ? false : x == 1 (note 0/1
should be handled already)

I'd hazard a guess we need to first eliminate the ad =  assignment.  That
should in turn allow us to realize ad is unchanging.

Interestingly enough this is picked up at -O3.  Looks like PRE does a better
job and the result is easier to discover the range for first operand of the
controlling conditional.

--- Comment #2 from Jeffrey A. Law  ---
It almost looks like a costing issue.  The threaders find opportunities to
thread all the incoming edges in the key block to the path which avoids the
call..  But all the paths get rejected.  


This is the  key block:

;;   basic block 11, loop depth 0, count 976284897 (estimated locally, freq
0.9092), maybe hot
;;prev block 10, next block 12, flags: (NEW, REACHABLE, VISITED)
;;pred:   10 [99.8% (guessed)]  count:225266786 (estimated locally,
freq 0.2098) (TRUE_VALUE,EXECUTABLE)
;;14 [100.0% (guessed)]  count:751018112 (estimated locally,
freq 0.6994) (TRUE_VALUE,EXECUTABLE)
  # o.10_11 = PHI <(10), o.10_28(14)>
  _17 = o.10_11 == 
  _20 = o.10_11 == 
  _27 = _20 | _17;
  if (_27 != 0)
goto ; [58.87%]
  else
goto ; [41.13%]

It's pretty obvious that 10->11 can thread to 6.  If we look at the other
incoming edge we need o.10_28 which comes from bb14 with the value   So that
path should be 14->10->11 threading to 6.

But they get rejected during threadfull2.

[gcc(refs/users/meissner/heads/work162)] Add -mcpu=future support.

[Michael Meissner via Gcc-cvs]

https://gcc.gnu.org/g:5180f01d1d48691a088a0074d5a402ab4530d7f7

commit 5180f01d1d48691a088a0074d5a402ab4530d7f7
Author: Michael Meissner 
Date:   Sat Mar 9 00:05:03 2024 -0500

Add -mcpu=future support.

This patch adds the future option to the -mcpu= and -mtune= switches.

This patch treats the future like a power11 in terms of costs and 
reassociation
width.

This patch issues a ".machine future" to the assembly file if you use
-mcpu=power11.

This patch defines _ARCH_PWR_FUTURE if the user uses -mcpu=future.

This patch allows GCC to be configured with the --with-cpu=future and
--with-tune=future options.

This patch passes -mfuture to the assembler if the user uses -mcpu=future.

[Bug tree-optimization/112545] [14 Regression] Size regression when using -Os starting with r14-569-g21e2ef2dc25

[law at gcc dot gnu.org via Gcc-bugs]

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=112545

--- Comment #2 from Jeffrey A. Law  ---
This looks like a missed case for singletons.

  _1 = d.9_28 <= 0;
  _2 = (signed short) _1;
  _3 = (signed short) d.9_28;
  c.a = 0;
  if (_2 == _3)
goto ; [0.00%]
  else
goto ; [100.00%]


Back substituting the condition is:

(d.9_28 <= 0) == d.9_28

d.9_28 <= 0 has a range [0,1]

The only value that can make that expression true is if d.9_28 has the value 0.

Results for 14.0.1 20240308 (experimental) [master r14-9399-gac829a89fb5] (GCC) testsuite on s390x-ibm-linux-gnu arch14

[gcc(refs/users/meissner/heads/work162)] Add -mcpu=power11 tests.

[Michael Meissner via Gcc-cvs]

commit c87c9fa6ccf75da5ddf2b774e7f40bec244a9bdc
Author: Michael Meissner 
Date:   Fri Mar 8 23:52:28 2024 -0500

Add -mcpu=power11 tests.

This patch adds some simple tests for -mcpu=power11 support.  In order to 
run
these tests, you need an assembler that supports the -mpwr11 option.

2024-03-08  Michael Meissner

* gcc.target/powerpc/power11-1.c: New test.
* gcc.target/powerpc/power11-2.c: Likewise.
* gcc.target/powerpc/power11-3.c: Likewise.
* lib/target-supports.exp (check_effective_target_power11_ok): Add 
new
effective target.

[gcc(refs/users/meissner/heads/work162)] Add -mcpu=power11 support.

[Michael Meissner via Gcc-cvs]

https://gcc.gnu.org/g:a2e7314507fe70f16adad23dbc68a421728ff6a0

commit a2e7314507fe70f16adad23dbc68a421728ff6a0
Author: Michael Meissner 
Date:   Fri Mar 8 23:48:20 2024 -0500

Add -mcpu=power11 support.

This patch adds the power11 option to the -mcpu= and -mtune= switches.

This patch treats the power11 like a power10 in terms of costs and 
reassociation
width.

This patch issues a ".machine power11" to the assembly file if you use
-mcpu=power11.

This patch defines _ARCH_PWR11 if the user uses -mcpu=power11.

This patch allows GCC to be configured with the --with-cpu=power11 and
--with-tune=power11 options.

This patch passes -mpwr11 to the assembler if the user uses -mcpu=power11.

This patch adds support for using "power11" in the __builtin_cpu_is built-in
function.

--- Comment #2 from Jeffrey A. Law  ---
So we could attack this as a DOM problem.  Not all the infrastructure is in
there.  But the recognition of negated expressions isn't hard.  Something like
this in tree-ssa-scopedtables will detect the negated expression in the hash
table.  

/* We might be able to lookup the negated expression.  */
case PLUS_EXPR:
  {
tree x = gimple_assign_rhs_to_tree (stmt);
x = fold_unary (NEGATE_EXPR, TREE_TYPE (x), x);
struct hashable_expr expr;
expr.type = TREE_TYPE (x);
expr.kind = EXPR_BINARY;
expr.ops.binary.op = MINUS_EXPR;
expr.ops.binary.opnd0 = TREE_OPERAND (x, 0);
expr.ops.binary.opnd1 = TREE_OPERAND (x, 1);
class expr_hash_elt element2 (, NULL_TREE);
expr_hash_elt **slot
  = m_avail_exprs->find_slot (, NO_INSERT);
if (slot && *slot)
  return fold_build1 (NEGATE_EXPR, TREE_TYPE (x),  (*slot)->lhs
());
return NULL_TREE;
  }

Right now DOM isn't prepared for avail_expr_stack::simplify_binary_operation to
return anything other than a constant, ssa_name or NULL.  But how hard could it
be to expand further :-)


Not sure if this happens enough to make the extra lookups worth the effort.

commit 6712015cc1f80178502cf904fef6102ce76022e0
Author: Michael Meissner 
Date:   Fri Mar 8 23:28:52 2024 -0500

Add -mcpu=future support part 3.

This patch makes -mtune=future use the same tuning decision as 
-mtune=power11.

[gcc(refs/users/meissner/heads/work162)] Add -mcpu=future support part 2

[Michael Meissner via Gcc-cvs]

https://gcc.gnu.org/g:ea0193ba078ba6d9747329266de9aa9b2a9bb5d5

commit ea0193ba078ba6d9747329266de9aa9b2a9bb5d5
Author: Michael Meissner 
Date:   Fri Mar 8 23:26:03 2024 -0500

Add -mcpu=future support part 2

This patch allows GCC to be configured with the --with-cpu=future and
--with-tune=future options.

This patch passes -mfutue to the assembler if the user uses -mcpu=future.

2024-03-08  Michael Meissner  

gcc/

* config.gcc (rs6000*-*-*, powerpc*-*-*): Add support for power11.
* config/rs6000/aix71.h (ASM_CPU_SPEC): Add support for 
-mcpu=power11.
* config/rs6000/aix72.h (ASM_CPU_SPEC): Likewise.

[gcc(refs/users/meissner/heads/work162)] Add -mcpu=future support.

[Michael Meissner via Gcc-cvs]

https://gcc.gnu.org/g:522bd06b7abf4de674693dc57569547e6de09306

commit 522bd06b7abf4de674693dc57569547e6de09306
Author: Michael Meissner 
Date:   Fri Mar 8 23:14:31 2024 -0500

Add -mcpu=future support.

This patch adds the future option to the -mcpu= and -mtune= switches.

This patch treats the future like a power11 in terms of costs and 
reassociation
width.

This patch issues a ".machine future" to the assembly file if you use
-mcpu=power11.

This patch defines _ARCH_PWR_FUTURE if the user uses -mcpu=future.

2024-03-08  Michael Meissner

--- Comment #2 from Jeffrey A. Law  ---
The other approach we could take (and which I think may have certain
advantages) would be to first realize this is a multiplication by a boolean
(0/1) value.  That's just a conditional move.  If we then rewrote as a
conditional move there's a reasonable chance we'd be able to further simplify.

The biggest problem with this approach is if we're aggressively transforming
into  conditional moves in gimple, the expanders will need improvement,
particularly on targets that don't have conditional moves.

Raphael has a TODO in this space.   He may have further thoughts.

[gcc(refs/users/meissner/heads/work162)] Add -mcpu=power11 tests.

[Michael Meissner via Gcc-cvs]

https://gcc.gnu.org/g:35fe3606f7e3a96836e68e99cca93c21ff9fb817

commit 35fe3606f7e3a96836e68e99cca93c21ff9fb817
Author: Michael Meissner 
Date:   Fri Mar 8 22:48:41 2024 -0500

Add -mcpu=power11 tests.

This patch adds some simple tests for -mcpu=power11 support.  In order to 
run
these tests, you need an assembler that supports the -mpwr11 option.

2024-03-08  Michael Meissner  

gcc/testsuite/

* gcc.target/powerpc/power11-1.c: New test.
* gcc.target/powerpc/power11-2.c: Likewise.
* gcc.target/powerpc/power11-3.c: Likewise.
* lib/target-supports.exp (check_effective_target_power11_ok): Add 
new
effective target.

[Michael Meissner via Gcc-cvs]

https://gcc.gnu.org/g:a09c97da2830f55b5cc1509f67188867df14cdf3

commit a09c97da2830f55b5cc1509f67188867df14cdf3
Author: Michael Meissner 
Date:   Fri Mar 8 22:47:22 2024 -0500

Add -mcpu=power11 support part 2

This patch allows GCC to be configured with the --with-cpu=power11 and
--with-tune=power11 options.

This patch passes -mpwr11 to the assembler if the user uses -mcpu=power11.

This patch adds support for using "power11" in the __builtin_cpu_is built-in
function.

[gcc(refs/users/meissner/heads/work162)] Add -mcpu=power11 support.

[Michael Meissner via Gcc-cvs]

https://gcc.gnu.org/g:79df8d6772b1aecab388c0853cac305837a18b18

commit 79df8d6772b1aecab388c0853cac305837a18b18
Author: Michael Meissner 
Date:   Fri Mar 8 22:46:47 2024 -0500

Add -mcpu=power11 support.

This patch adds the power11 option to the -mcpu= and -mtune= switches.

This patch treats the power11 like a power10 in terms of costs and 
reassociation
width.

This patch issues a ".machine power11" to the assembly file if you use
-mcpu=power11.

This patch defines _ARCH_PWR11 if the user uses -mcpu=power11.

2024-03-08  Michael Meissner  

gcc/

* config/rs6000/rs6000-c.cc (rs6000_target_modify_macros): Define
_ARCH_PWR11 if -mcpu=power11.

Since compressed sections begin with a compression header
structure that identifies the compression algorithm, compressed
sections must be aligned to the alignment of the compression
header.  I don't think there is any ambiguity here.

--- Comment #10 from Nathaniel Shead  ---
I now have access to an Aarch64 machine via the build farm. My patch in #c7 is
not sufficient to get the minimised testcase working (need to update the
assumptions on VECTOR_TYPEs too) and it looks like we'll need to work out how
to stream the aarch64-specific types found in the 'registered_builtin_types'
list too, like __fp16.

I'll submit a patch to the mailing lists once I've worked out the details.

100% agree!  If you look at what we (IBM) post, we roughly post somewhere
around 7 testsuite results per day due to runs on different hardware,
endianness and OS (Linux versus AIX).  So spam ...err... post away!

Again, 100% agree!

Re: [pushed][PATCH v1] LoongArch: Fixed an issue with the implementation of the template atomic_compare_and_swapsi.

[chenglulu]

Pushed to r14-9407.

在 2024/3/7 上午9:12, Lulu Cheng 写道:

If the hardware does not support LAMCAS, atomic_compare_and_swapsi needs to be
implemented through "ll.w+sc.w". In the implementation of the instruction 
sequence,
it is necessary to determine whether the two registers are equal.
Since LoongArch's comparison instructions do not distinguish between 32-bit
and 64-bit, the two operand registers that need to be compared are symbolically
extended, and one of the operand registers is obtained from memory through the
"ll.w" instruction, which can ensure that the symbolic expansion is carried out.
However, the value of the other operand register is not guaranteed to be the
value of the sign extension.

gcc/ChangeLog:

* config/loongarch/sync.md (atomic_cas_value_strong):
In loongarch64, a sign extension operation is added when
operands[2] is a register operand and the mode is SImode.

gcc/testsuite/ChangeLog:

* g++.target/loongarch/atomic-cas-int.C: New test.

commit r14-9408-g6fe63013e3292a45288461b7efa9d52e0ac234dc
Author: Lulu Cheng 
Date:   Thu Mar 7 09:44:03 2024 +0800

LoongArch: testsuite: Add compilation options to the regname-fp-s9.c.

When the value of the macro DEFAULT_CFLAGS is set to '-ansi 
-pedantic-errors',
regname-s9-fp.c will test to fail. To solve this problem, add the 
compilation
option '-Wno-pedantic -std=gnu90' to this test case.

gcc/testsuite/ChangeLog:

* gcc.target/loongarch/regname-fp-s9.c: Add compilation option
'-Wno-pedantic -std=gnu90'.

[gcc r14-9407] LoongArch: Fixed an issue with the implementation of the template atomic_compare_and_swapsi.

[LuluCheng via Gcc-cvs]

https://gcc.gnu.org/g:3a3fbec0a4d3f36de58df9ef0b3992a3ffb359c2

commit r14-9407-g3a3fbec0a4d3f36de58df9ef0b3992a3ffb359c2
Author: Lulu Cheng 
Date:   Tue Mar 5 14:43:04 2024 +0800

LoongArch: Fixed an issue with the implementation of the template 
atomic_compare_and_swapsi.

If the hardware does not support LAMCAS, atomic_compare_and_swapsi needs to 
be
implemented through "ll.w+sc.w". In the implementation of the instruction 
sequence,
it is necessary to determine whether the two registers are equal.
Since LoongArch's comparison instructions do not distinguish between 32-bit
and 64-bit, the two operand registers that need to be compared are 
symbolically
extended, and one of the operand registers is obtained from memory through 
the
"ll.w" instruction, which can ensure that the symbolic expansion is carried 
out.
However, the value of the other operand register is not guaranteed to be the
value of the sign extension.

gcc/ChangeLog:

* config/loongarch/sync.md (atomic_cas_value_strong):
In loongarch64, a sign extension operation is added when
operands[2] is a register operand and the mode is SImode.

gcc/testsuite/ChangeLog:

* g++.target/loongarch/atomic-cas-int.C: New test.

It should be better to extend the expected value before the ll/sc loop
(like what LLVM does), instead of repeating the extending in each
iteration.  Something like:

I wanted to do this at first, but it didn't work out.

But then I thought about it, and there are two benefits to putting it in
the middle of ll/sc:

1. If there is an operation that uses the $r4 register after this atomic
operation, another

register is required to store $r4.

2. ll.w requires long cycles, so putting an addi.w command after ll.w
won't make a difference.

So based on the above, I didn't try again, but directly made a
modification like a patch.

Ah, the explanation makes sense to me.  Ok with the original patch then.

Ok.Thank you so much!:-)

[committed] libstdc++: Do not require a time-of-day when parsing sys_days [PR114240]

[Jonathan Wakely]

Tested x86_64-linux. Pushed to trunk.

-- >8 --

When parsing a std::chrono::sys_days (or a sys_time with an even longer
period) we should not require a time-of-day to be present in the input,
because we can't represent that in the result type anyway.

Rather than trying to decide which specializations should require a
time-of-date and which should not, follow the direction of Howard
Hinnant's date library, which allows extracting a sys_time of any period
from input that only contains a date, defaulting the time-of-day part to
00:00:00. This seems consistent with the intent of the standard, which
says it's an error "If the parse fails to decode a valid date" (i.e., it
doesn't care about decoding a valid time, only a date).

[committed] libstdc++: Fix parsing of leap seconds as chrono::utc_time [PR114279]

[Jonathan Wakely]

Tested x86_64-linux. Pushed to trunk.

-- >8 --

Implementing all chrono::from_stream overloads in terms of
chrono::sys_time meant that a leap second time like 23:59:60.001 cannot
be parsed, because that cannot be represented in a sys_time.

The fix to support parsing leap seconds as utc_time is to convert the
parsed date to utc_time and then add the parsed time to that,
which allows the result to land in a leap second, rather than doing all
the arithmetic with sys_time which doesn't have leap seconds.

For local_time we also allow %S to parse a 60s value, because doing
otherwise might disallow some valid uses. We can't know all use cases
users have for treating times as local_time.

For all other clocks, we can reject times that have 60 or 60.nnn as the
seconds part, because that cannot occur in a valid UNIX, GPS, or TAI
time. Since our chrono::file_clock uses sys_time, it can't occur for
that clock either.

In order to support this a new _M_is_leap_second member is needed in the
_Parser type. This can be added at the end, where most targets currently
have padding bytes. Similar to what I did recently for formatter _Spec
structs, we can also reserve additional padding bits for future
expansion.

This also fixes bugs in the from_stream overloads for utc_time,
tai_time, gps_time, and file_time, which were not using time_point_cast
to explicitly convert to the result type. That's needed because the
result type might have lower precision than the value returned from
from_sys or from_utc, which has a precision no lower than seconds.

libstdc++-v3/ChangeLog:

* include/bits/chrono_io.h (_Parser::_M_is_leap_second): New
data member.
(_Parser::_M_reserved): Reserve padding bits for future use.

are preserved. Use time_point_cast to convert to a possibly
lower-precision result type.

libstdc++: Fix parsing of leap seconds as chrono::utc_time [PR114279]

Implementing all chrono::from_stream overloads in terms of
chrono::sys_time meant that a leap second time like 23:59:60.001 cannot
be parsed, because that cannot be represented in a sys_time.

The fix to support parsing leap seconds as utc_time is to convert the
parsed date to utc_time and then add the parsed time to that,
which allows the result to land in a leap second, rather than doing all
the arithmetic with sys_time which doesn't have leap seconds.

For local_time we also allow %S to parse a 60s value, because doing
otherwise might disallow some valid uses. We can't know all use cases
users have for treating times as local_time.

For all other clocks, we can reject times that have 60 or 60.nnn as the
seconds part, because that cannot occur in a valid UNIX, GPS, or TAI
time. Since our chrono::file_clock uses sys_time, it can't occur for
that clock either.

In order to support this a new _M_is_leap_second member is needed in the
_Parser type. This can be added at the end, where most targets currently
have padding bytes. Similar to what I did recently for formatter _Spec
structs, we can also reserve additional padding bits for future
expansion.

This also fixes bugs in the from_stream overloads for utc_time,
tai_time, gps_time, and file_time, which were not using time_point_cast
to explicitly convert to the result type. That's needed because the
result type might have lower precision than the value returned from
from_sys or from_utc, which has a precision no lower than seconds.

libstdc++-v3/ChangeLog:

PR libstdc++/114279
* include/bits/chrono_io.h (_Parser::_M_is_leap_second): New
data member.
(_Parser::_M_reserved): Reserve padding bits for future use.
(_Parser::operator()): Set _M_is_leap_second if %S reads 60s.
(from_stream): Only allow _M_is_leap_second for utc_time and
local_time. Adjust arithmetic for utc_time so that leap seconds
are preserved. Use time_point_cast to convert to a possibly
lower-precision result type.
* testsuite/std/time/parse.cc: Move to ...
* testsuite/std/time/parse/parse.cc: ... here.
* testsuite/std/time/parse/114279.cc: New test.

[gcc r14-9403] ipa: Avoid excessive removing of SSAs (PR 113757)

[Martin Jambor via Gcc-cvs]

https://gcc.gnu.org/g:54e505d0446f86b7ad383acbb8e5501f20872b64

commit r14-9403-g54e505d0446f86b7ad383acbb8e5501f20872b64
Author: Martin Jambor 
Date:   Sat Mar 9 00:47:22 2024 +0100

ipa: Avoid excessive removing of SSAs (PR 113757)

PR 113757 shows that the code which was meant to debug-reset and
remove SSAs defined by LHSs of calls redirected to
__builtin_unreachable can trigger also when speculative
devirtualization creates a call to a noreturn function (and since it
is noreturn, it does not bother dealing with its return value).

What is more, it seems that the code handling this case is not really
necessary.  I feel slightly idiotic about this because I have a
feeling that I added it because of a failing test-case but I can
neither find the testcase nor a reason why the code in
cgraph_edge::redirect_call_stmt_to_callee would not be sufficient (it
turns the SSA name into a default-def, a bit like IPA-SRA, but any
code dominated by a call to a noreturn is not dangerous when it comes
to its side-effects).  So this patch just removes the handling.

Sending test results to the gcc-testresults list is **not** spamming,
that's what the list is for!

https://gcc.gnu.org/pipermail/gcc-testresults/2024-March/date.html

If you're testing uncommon targets (e.g. ia64-linux) then sending test
results to the list is essential so we know the target builds, because
nobody else is testing it.
