This patch is preventive: it improves checks on inline functions that
return unconstrained type. It does not change the functionality of
the compiler.

The frontend generates special functions for checking subtype predicates,
type invariants and Default_Initial_Condition aspect. These are translated
as predicates in GNATprove, and as such should no call inside these
functions should be inlined. This is similar to the existing handling of
calls inside expression functions.
There is no impact on compilation.

The compiler fails to generate a call to detect allocators executed after
elaboration in cases where the allocator is associated with Global_Pool_Object.
The fix is to test for this associated storage pool as part of the condition
for generating a call to System.Elaboration_Allocators.Check_Standard_Alloctor.
Also, the exception Storage_Error is now generated instead of Program_Error
for such a run-time violation, as required by the Ada RM in D.7.
The following test must compile and execute quietly:
-- Put the pragma in gnat.adc:
pragma Restrictions (No_Standard_Allocators_After_Elaboration);
package Pkg_With_Allocators is
type Priv is private;
procedure Allocate
(Use_Global_Allocator : Boolean;
During_Elaboration : Boolean);
private
type Rec is record
Int : Integer;
end record;
type Priv is access Rec;
end Pkg_With_Allocators;

(Use_Global_Allocator : Boolean;
During_Elaboration : Boolean)
is
type Local_Acc is access Rec;
Local_Ptr : Local_Acc;
begin
if Use_Global_Allocator then
Ptr := new Rec; -- Raise Storage_Error if after elaboration
Ptr.Int := 1;
else
Local_Ptr := new Rec; -- Raise Storage_Error if after elaboration
Local_Ptr.Int := 1;
end if;
if not During_Elaboration then
raise Program_Error; -- No earlier exception: FAIL
end if;
exception

if During_Elaboration then
raise Program_Error; -- No exception expected: FAIL
else

end if;

end Allocate;

is pushed in the prologue and popped in the epilogue:

However, when we adjust those insns in vartrack to eliminate the pre_dec and

The libffi library doesn't understand zero-sized objects.
When we see a zero-sized field in a struct, just skip it when
converting to the FFI data structures. There is no value to pass in
any case, so not telling libffi about the field doesn't affect
anything.
The test case for this is https://golang.org/cl/123316.

r259399, which added PROCESSOR_SKYLAKE, disabled many x86 optimizations
which are enabled by PROCESSOR_HASWELL. As the result, -mtune=skylake
generates slower codes on Skylake than before. The same also applies
to Cannonlake and Icelak tuning.
This patch changes -mtune={skylake|cannonlake|icelake} to tune like
-mtune=haswell for until their tuning is properly adjusted. It also
enables -mprefer-vector-width=256 for -mtune=haswell, which has no
impact on codegen when AVX512 isn't enabled.

Inline strcmp with small constant strings
The design doc for PR78809 is at:
https://www.mail-archive.com/gcc@gcc.gnu.org/msg83822.html
this patch is for the third part of change of PR78809.
C. for strcmp (s1, s2), strncmp (s1, s2, n), and memcmp (s1, s2, n)
if the result is NOT used to do simple equality test against zero, one of
"s1" or "s2" is a small constant string, n is a constant, and the Min value of
the length of the constant string and "n" is smaller than a predefined
threshold T,
inline the call by a byte-to-byte comparision sequence to avoid calling
overhead.
adding test case strcmpopt_5.c into gcc.dg for part C of PR78809.
adding test case strcmpopt_6.c into gcc.dg to test the following case:
When the specified length exceeds one of the arguments of the call to memcmp,
the call to memcmp should NOT be inlined.

This patch moves the vendor and CPU id data from driver-arm.c to the
main table of CPU data in arm-cpus.in. It then adds rules to
parsecpu.awk to build data tables that can be used by the driver for
automatic CPU detection when running natively. This is the last major
bit of CPU-specific data that can be usefully moved to the CPU data
tables (I don't think it is sensible to move the per-cpu tuning data
from its current location).
The syntax and parser can support revision ranges, but at present
nothing is done with that data: no supported cpu currently needs that
capability.
* config/arm/driver-arm.c: Include arm-native.h.
(host_detect_local_cpu): Use auto-generated data tables.
(vendors, arm_cpu_table): Delete. Move part information to ...
* config/arm/arm-cpus.in: ... here.
* config/arm/parsecpu.awk (gen_native): New function.
(vendor, part): New CPU fields.
(END): Add support for building the native CPU detection tables.
* config/arm/t-arm (arm-native.h): Add build rule.
(driver-arm.o): Add dependency on arm-native.h.

Optimization fipa-icf breaks debug info (as is noted in PR63572 - "ICF
breaks user debugging experience"), which make guality tests clztest.c,
ctztest.c and sra-1.c unsupported for option combination "-O2 -flto
-fuse-linker-plugin -fno-fat-lto-objects". F.i., in clztest.c foo and bar are
merged, and gdb can set a breakpoint on a line in foo, but trying to set a
breakpoint on a line in bar results in a breakpoint in main instead.
This patch works around the problem by adding -fno-ipa-icf (as is already done
in csttest.c and pr43077-1.c) to those testcases:
...
-UNSUPPORTED: gcc.dg/guality/clztest.c ... line . g == f
+PASS: gcc.dg/guality/clztest.c ... line . g == f
-UNSUPPORTED: gcc.dg/guality/ctztest.c ... line . g == f
+PASS: gcc.dg/guality/ctztest.c ... line . g == f
-UNSUPPORTED: gcc.dg/guality/sra-1.c ... line .+1 a[0] == 4
+PASS: gcc.dg/guality/sra-1.c ... line .+1 a[0] == 4
-UNSUPPORTED: gcc.dg/guality/sra-1.c ... line . a[1] == 14
+PASS: gcc.dg/guality/sra-1.c ... line . a[1] == 14
...
Tested on x86_64.

When compiling gcc.dg/vla-1.c with -O3 -g, vla a and b in f1 are optimized
away, and f1 is cloned to a version f1.constprop with no parameters, eliminating
parameter i. Debug info is generated to describe the sizes of a and b, but
that process generates debug expressions that are not reused.
Fix the duplication by saving and reusing the generated debug expressions in
remap_ssa_name. Concretely: reuse D#7 here instead of generating D#8:
...
__attribute__((noinline))
f1.constprop ()
{
intD.6 iD.1935;
<bb 3>
# DEBUG D#10 s=> iD.1897
# DEBUG iD.1935 => D#10
<bb 2>
- # DEBUG D#8 s=> iD.1935
# DEBUG D#7 s=> iD.1935
saved_stack.2_1 = __builtin_stack_save ();
# DEBUG BEGIN_STMT
# DEBUG D#6 => D#7 + 1
# DEBUG D#5 => (long intD.8) D#6
# DEBUG D#4 => D#5 + -1
# DEBUG D.1937 => (sizetype) D#4
# DEBUG a.0D.1942 => NULL
# DEBUG BEGIN_STMT
- # DEBUG D#3 => D#8 + 2
+ # DEBUG D#3 => D#7 + 2
# DEBUG D#2 => (long intD.8) D#3
# DEBUG D#1 => D#2 + -1
# DEBUG D.1944 => (sizetype) D#1
# DEBUG b.1D.1949 => NULL
...
Bootstrapped and reg-tested on x86_64.
