LoongArch: Add constraints for bit string operation define_insn_and_split's

[gcc r15-10] RISC-V: Add -X to link spec
https://gcc.gnu.org/g:50c218e3ffe57860591a987ecf44fcc0abb31f2c
commit r15-10-g50c218e3ffe57860591a987ecf44fcc0abb31f2c
Author: Fangrui Song
Date: Fri Apr 26 18:14:33 2024 -0700
RISC-V: Add -X to link spec
--discard-locals (-X) instructs the linker to remove local .L* symbols,
which occur a lot due to label differences for linker relaxation. The
arm port has a similar need and passes -X to ld.
In contrast, the RISC-V port does not pass -X to ld and rely on the
default --discard-locals in GNU ld's riscv port. The arm way is more
conventional (compiler driver instead of the linker customizes the
default linker behavior) and works with lld.
gcc/ChangeLog:
* config/riscv/elf.h (LINK_SPEC): Add -X.
* config/riscv/freebsd.h (LINK_SPEC): Add -X.
* config/riscv/linux.h (LINK_SPEC): Add -X.

Cleanup memset implementation. Similar to memcpy/memmove, use an offset and
bytes throughout. Simplify the complex calculations when optimizing for
size
by using a fixed limit.

Remove the tune AARCH64_EXTRA_TUNE_NO_LDP_STP_QREGS since it is only
used by an old core and doesn't properly support -Os. SPECINT_2017
shows that removing it has no performance difference, while codesize
is reduced by 0.07%.

[gcc r14-10140] c++: fix source printing for "required from here" message
https://gcc.gnu.org/g:c014cfd8853240827feb3a4cef92403e83cd4265
commit r14-10140-gc014cfd8853240827feb3a4cef92403e83cd4265

c++: fix source printing for "required from here" message
It seems the diagnostic machinery's source line printing respects
the pretty printer prefix, but this is undesirable for the call to
diagnostic_show_locus in print_instantiation_partial_context_line
(added in r14-4388-g1c45319b66edc9) since the prefix may have been
set when issuing an earlier, unrelated diagnostic and we just want
to print an unprefixed source line.
This patch naively fixes this by clearing the prefix before calling
diagnostic_show_locus.
Before this patch, for error60a.C below we'd print

commit r14-10138-gb8e9fd535d6093e3a24af858364d8517a767b0d7
Author: Frederik Harwath
Date: Wed Apr 24 20:29:14 2024 +0200
amdgcn: Add gfx90c target
Add support for gfx90c GCN5 APU integrated graphics devices.
The LLVM AMDGPU documentation does not list those devices as supported
by rocm-amdhsa, but it passes most libgomp offloading tests.
Although they are constrainted compared to dGPUs, they might be
interesting for learning, experimentation, and testing.
gcc/ChangeLog:
* config.gcc: Add gfx90c.
* config/gcn/gcn-hsa.h (NO_SRAM_ECC): Likewise.
* config/gcn/gcn-opts.h (enum processor_type): Likewise.
(TARGET_GFX90c): New macro.
* config/gcn/gcn.cc (gcn_option_override): Handle gfx90c.
(gcn_omp_device_kind_arch_isa): Likewise.
(output_file_start): Likewise.
* config/gcn/gcn.h: Add gfx90c.
* config/gcn/gcn.opt: Likewise.
* config/gcn/mkoffload.cc (EF_AMDGPU_MACH_AMDGCN_GFX90c): New macro.
(get_arch): Handle gfx90c.
(main): Handle EF_AMDGPU_MACH_AMDGCN_GFX90c
* config/gcn/t-omp-device: Add gfx90c.
* doc/install.texi: Likewise.
* doc/invoke.texi: Likewise.
libgomp/ChangeLog:
* plugin/plugin-gcn.c (isa_hsa_name): Handle
EF_AMDGPU_MACH_AMDGCN_GFX90c.
(isa_code): Handle gfx90c.
(max_isa_vgprs): Handle EF_AMDGPU_MACH_AMDGCN_GFX90c.

gfortran: Allow ref'ing PDT's len() in parameter-initializer.
Fix declaring a parameter initialized using a pdt_len reference
not simplifying the reference to a constant.
2023-07-12 Andre Vehreschild
gcc/fortran/ChangeLog:
PR fortran/102003
* expr.cc (find_inquiry_ref): Replace len of pdt_string by
constant.
(simplify_ref_chain): Ensure input to find_inquiry_ref is
NULL.
(gfc_match_init_expr): Prevent PDT analysis for function calls.
(gfc_pdt_find_component_copy_initializer): Get the initializer
value for given component.
* gfortran.h (gfc_pdt_find_component_copy_initializer): New
function.
* simplify.cc (gfc_simplify_len): Replace len() of PDT with pdt
component ref or constant.
gcc/testsuite/ChangeLog:
* gfortran.dg/pdt_33.f03: New test.
