[gcc r15-3224] arm: Always use vmov.f64 instead of vmov.f32 with MVE

arm: Always use vmov.f64 instead of vmov.f32 with MVE

With MVE, vmov.f64 is always supported (no need for +fp.dp extension).

This patch updates two patterns:
- in movdi_vfp, we incorrectly checked
  TARGET_VFP_SINGLE || TARGET_HAVE_MVE instead of
  TARGET_VFP_SINGLE && !TARGET_HAVE_MVE, and didn't take into account
  these two possibilities when computing the length attribute.

- in thumb2_movdf_vfp, we checked only TARGET_VFP_SINGLE.

No need to update movdf_vfp, since it is enabled only for TARGET_ARM
(which is not the case when MVE is enabled).

The patch also updates gcc.target/arm/armv8_1m-fp64-move-1.c, to
accept only vmov.f64 instead of vmov.f32.

Tested on arm-none-eabi with:
qemu/-mthumb/-mtune=cortex-m55/-mfloat-abi=hard/-mfpu=auto

qemu/-mthumb/-mtune=cortex-m55/-mfloat-abi=hard/-mfpu=auto/-march=armv8.1-m.main+mve

qemu/-mthumb/-mtune=cortex-m55/-mfloat-abi=hard/-mfpu=auto/-march=armv8.1-m.main+mve.fp

qemu/-mthumb/-mtune=cortex-m55/-mfloat-abi=hard/-mfpu=auto/-march=armv8.1-m.main+mve.fp+fp.dp

[gcc r15-1708] i386: Fix regression after refactoring legitimize_pe_coff_symbol, ix86_GOT_alias_set and PE_COFF_LEG

i386: Fix regression after refactoring legitimize_pe_coff_symbol, 
ix86_GOT_alias_set and PE_COFF_LEGITIMIZE_EXTERN_DECL [PR115635]

This patch fixes 3 bugs reported after merging the "Add DLL
import/export implementation to AArch64" series.
https://gcc.gnu.org/pipermail/gcc-patches/2024-June/653955.html The
series refactors the i386 codebase to reuse it in AArch64, which
triggers some bugs.

Bug 115661 - [15 Regression] wrong code at -O{2,3} on x86_64-linux-gnu
since r15-1599-g63512c72df09b4
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=115661

Bug 115635 - [15 regression] Bootstrap fails with failed self-test
with the rust fe (diagnostic-path.cc:1153: test_empty_path: FAIL:
ASSERT_FALSE ((path.interprocedural_p ( since
r15-1599-g63512c72df09b4
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=115635

Issue 1. In some code, i386 has been relying on the
legitimize_pe_coff_symbol call on all platforms and should return
NULL_RTX if it is not supported.

Fix: NULL_RTX handling has been added when the target does not support
PECOFF.

Issue 2. ix86_GOT_alias_set is used on all platforms and cannot be
extracted to mingw.

Fix: ix86_GOT_alias_set has been returned as it was and is used on all
platforms for i386.

Bug 115643 - [15 regression] aarch64-w64-mingw32 support today breaks
x86_64-w64-mingw32 build cannot represent relocation type BFD_RELOC_64
since r15-1602-ged20feebd9ea31
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=115643

Issue 3. PE_COFF_EXTERN_DECL_SHOULD_BE_LEGITIMIZED has been added and
used with a negative operator for a complex expression without braces.

Fix: Braces has been added, and
PE_COFF_EXTERN_DECL_SHOULD_BE_LEGITIMIZED has been renamed to
PE_COFF_LEGITIMIZE_EXTERN_DECL.

This patch extends the aarch64 attributes list with the selectany
attribute for the aarch64-w64-mingw32 target and reuses the mingw
implementation to handle it.

gcc/ChangeLog:
* config/aarch64/aarch64.cc: Extend the aarch64 attributes list.
* config/aarch64/cygming.h (SUBTARGET_ATTRIBUTE_TABLE): Define the
selectany attribute.

Extract ix86 dllimport implementation to mingw

This patch extracts the ix86 implementation for expanding a SYMBOL
into its corresponding dllimport, far-address, or refptr symbol.  It
will be reused in the aarch64-w64-mingw32 target.  The implementation
is copied as is from i386/i386.cc with minor changes to follow to the
code style.

Also this patch replaces the original DLL import/export implementation
in ix86 with mingw.

* config.gcc: Add winnt-dll.o, which contains the DLL
import/export implementation.

old implementation. Rename the required function to MinGW.

Move mingw_* declarations to the mingw folder

This patch refactors recent changes to move mingw-related
functionality to the mingw folder. More renamings to the mingw_ prefix
will be done in follow-up commits.

This is the first commit in the second patch series to add DLL
import/export implementation to AArch64.

after moving MinGW files.
* config/i386/t-gthr-win32: Move to...

Exclude i386 functionality from aarch64 build

This patch defines TARGET_AARCH64_MS_ABI in config.gcc and uses it to
exclude i386 functionality from aarch64 build and adjust MinGW headers
for AArch64 MS ABI.

gcc/ChangeLog:

* config.gcc: Define TARGET_AARCH64_MS_ABI.
* config/mingw/mingw-stdint.h (INTPTR_TYPE): Use
TARGET_AARCH64_MS_ABI to adjust MinGW headers for
AArch64 MS ABI.
(UINTPTR_TYPE): Likewise.
(defined): Likewise.
* config/mingw/mingw32.h (DEFAULT_ABI): Likewise.
(defined): Likewise.
* config/mingw/winnt.cc (defined): Use TARGET_ARM64_MS_ABI to
exclude ix86_get_callcvt.
(i386_pe_maybe_mangle_decl_assembler_name): Likewise.
(i386_pe_mangle_decl_assembler_name): Likewise.

aarch64: Mark x18 register as a fixed register for MS ABI

Define the MS ABI for aarch64-w64-mingw32.
Adjust FIXED_REGISTERS, CALL_REALLY_USED_REGISTERS and
STATIC_CHAIN_REGNUM for AArch64 MS ABI.
The X18 register is reserved on Windows for the TEB.

gcc/ChangeLog:

* config.gcc: Define TARGET_AARCH64_MS_ABI when
AArch64 MS ABI is used.
* config/aarch64/aarch64.h (FIXED_X18): Adjust
FIXED_REGISTERS, CALL_REALLY_USED_REGISTERS and
STATIC_CHAIN_REGNUM for AArch64 MS ABI.
(CALL_USED_X18): Likewise.
(FIXED_REGISTERS): Likewise.
* config/aarch64/aarch64-abi-ms.h: New file.

arm: [MVE intrinsics] Fix support for loads [PR target/114323]

The testcase in this PR shows that we would load from an uninitialized
location, because the vld1 instrinsics are reported as "const". This
is because function_instance::reads_global_state_p() does not take
CP_READ_MEMORY into account.  Fixing this gives vld1 the "pure"
attribute instead, and solves the problem.
