I've tried to build stage3 with
-Wleading-whitespace=blanks -Wtrailing-whitespace=blank -Wno-error=leading-whitespace=blanks -Wno-error=trailing-whitespace=blank
added to STRICT_WARN and that expectably resulted in about
2744 unique trailing whitespace warnings and 124837 leading whitespace
warnings when excluding *.md files (which obviously is in big part a
generator issue). Others from that are generator related, I think those
need to be solved later.
The following patch just fixes up the easy case (trailing whitespace),
which could be easily automated:
for i in `find . -name \*.h -o -name \*.cc -o -name \*.c | xargs grep -l '[ ]$' | grep -v testsuite/`; do sed -i -e 's/[ ]*$//' $i; done
I've excluded files which I knew are obviously generated or go FE.
Is there anything else we'd want to avoid the changes?
Due to patch size, I've split it between gcc/ part
and rest (include/, libiberty/, libgcc/, libcpp/, libstdc++-v3/;
this part).

My forthcoming patches for PR other/116613 make much more use of
cloning of pretty_printers than before, so it makes sense as a
preliminary patch for the result of pretty_printer::clone to be a
std::unique_ptr, rather than add more manual uses of "delete".
On doing so, I noticed various other places where naked new/delete is
used for run-time configuration of diagnostics:
* the output format (text vs SARIF)
* client data hooks
* the option manager
* the URLifier
Hence this patch also makes use of std::unique_ptr and ::make_unique for
managing such client policy classes, and also for diagnostic_buffer's
per-format implementations.
Unfortunately we can't directly include <memory> in our internal headers
but instead any of our TUs that make use of std::unique_ptr must #define
INCLUDE_MEMORY before including system.h.
Hence the bulk of this patch is taken up with adding a define of
INCLUDE_MEMORY to hundreds of source files: everything that includes
diagnostic.h or pretty-print.h (and thus anything transitively such as
includers of lto-wrapper.h, c-tree.h, cp-tree.h and rtl-ssa.h).
Thanks to Gaius Mulley for the parts of the patch that regenerated the
m2 files.

Commit c608ada288ced0268bbbbc1fd4136f56c34b24d4
Author: Zac Walker <zacwalker@microsoft.com>
CommitDate: 2024-01-23 15:32:30 +0000
Ifdef `.hidden`, `.type`, and `.size` pseudo-ops for `aarch64-w64-mingw32` target
lse.S includes aarch64-asm.h, leading to a conflicting definition of macro 'L':
- in lse.S it expands to either '' or 'L'
- in aarch64-asm.h it is used to generate .L ## label
lse.S does not use the second, so this patch just undefines L after
the inclusion of aarch64-asm.h.

* config/aarch64/lse.S: Undefine L() macro.

__riscv_vendor_feature_bits
This provides a common abstraction layer to probe the available extensions at
run-time. These functions can be used to implement function multi-versioning or
to detect available extensions.
The advantages of providing this abstraction layer are:
- Easy to port to other new platforms.
- Easier to maintain in GCC for function multi-versioning.
- For example, maintaining platform-dependent code in C code/libgcc is much
easier than maintaining it in GCC by creating GIMPLEs...
This API is intended to provide the capability to query minimal common available extensions on the system.
The API is defined in the riscv-c-api-doc:
https://github.com/riscv-non-isa/riscv-c-api-doc/blob/main/src/c-api.adoc
Proposal to use unsigned long long for marchid and mimpid:
https://github.com/riscv-non-isa/riscv-c-api-doc/pull/91
Full function multi-versioning implementation will come later. We are posting
this first because we intend to backport it to the GCC 14 branch to unblock
LLVM 19 to use this with GCC 14.2, rather than waiting for GCC 15.
Changes since v7:
- Remove vendorID field in __riscv_vendor_feature_bits.
- Fix C implies Zcf only for RV32.
- Add more comments to kernel versions.
Changes since v6:
- Implement __riscv_cpu_model.
- Set new sub extension bits which implied from previous extensions.
Changes since v5:
- Minor fixes on indentation.
Changes since v4:
- Bump to newest riscv-c-api-doc with some new extensions like Zve*, Zc*
Zimop, Zcmop, Zawrs.
- Rename the return variable name of hwprobe syscall.
- Minor fixes on indentation.
Changes since v3:
- Fix non-linux build.
- Let __init_riscv_feature_bits become constructor
Changes since v2:
- Prevent it initialize more than once.
Changes since v1:

A previous patch ([1]) introduced a build regression on aarch64-none-elf
target. The changes were primarilly tested on aarch64-unknown-linux-gnu,
so the issue was missed during development.
The includes are slighly different between the two targets, and due to some
include rules ([2]), "aarch64-unwind-def.h" was not found.

d9cafa0c4f0a stopped building libgcc_s.1 on macOS >= 15, in part because
that is required to bootstrap the compiler using the macOS 15 SDK. The
macOS 15 SDK ships in Xcode 16, which also runs on macOS 14. libgcc_s.1
can no longer be built on macOS 14 using Xcode 16 by the same logic that
the previous change disabled it for macOS 15.

In C++20, modules streaming check for exposures of TU-local entities.
In general exposing internal linkage functions in a header is liable to
cause ODR violations in C++, and this is now detected in a module
context.
This patch goes through and removes 'static' from many declarations
exposed through libstdc++ to prevent code like the following from
failing:
export module M;
extern "C++" {
#include <bits/stdc++.h>
}
Since gthreads is used from C as well, we need to choose whether to use
'inline' or 'static inline' depending on whether we're compiling for C
or C++ (since the semantics of 'inline' are different between the
languages). Additionally we need to remove static global variables, so
we migrate these to function-local statics to avoid the ODR issues.
There doesn't seem to be a good workaround for weakrefs, so I've left
them as-is and will work around it in the modules streaming code to
consider them as not TU-local.
The same issue occurs in the objective-C specific parts of gthreads, but
I'm not familiar with the surrounding context and we don't currently
test modules with Objective C++ anyway so I've left it as-is.

We have been building a legacy libgcc_s.1 DSO to support code that
was built with older compilers.
From macOS 15, the unwinder no longer exports some of the symbols used
in that library which (a) cuases bootstrap fail and (b) means that the
legacy library is no longer useful.
No open branch of GCC emits references to this library - and any already
-built code that depends on the symbols would need rework anyway.

Architecture-specific CFI directives are currently declared an processed
among others architecture-independent CFI directives in gcc/dwarf2* files.
This approach creates confusion, specifically in the case of DWARF
instructions in the vendor space and using the same instruction code.
Such a clash currently happen between DW_CFA_GNU_window_save (used on
SPARC) and DW_CFA_AARCH64_negate_ra_state (used on AArch64), and both
having the same instruction code 0x2d.
Then AArch64 compilers generates a SPARC CFI directive (.cfi_window_save)
instead of .cfi_negate_ra_state, contrarilly to what is expected in
[DWARF for the Arm 64-bit Architecture (AArch64)](https://github.com/
ARM-software/abi-aa/blob/main/aadwarf64/aadwarf64.rst).
This refactoring does not solve completely the problem, but improve the
situation by moving some of the processing of those directives (more
specifically their output in the assembly) to the backend via 2 target
hooks:
- DW_CFI_OPRND1_DESC: parse the first operand of the directive (if any).
- OUTPUT_CFI_DIRECTIVE: output the CFI directive as a string.
Additionally, this patch also contains a renaming of an enum used for
return address mangling on AArch64.

handler.
This patch provides a new handler MD_ARCH_FRAME_STATE_T to hide an
architecture-specific structure containing CIE and FDE data related
to DWARF architecture extensions.
Hiding the architecture-specific attributes behind a handler has the
following benefits:
1. isolating those data from the generic ones in _Unwind_FrameState
2. avoiding casts to custom types.
3. preserving typing information when debugging with GDB, and so
facilitating their printing.
This approach required to add a new header md-unwind-def.h included at
the top of libgcc/unwind-dw2.h, and redirecting to the corresponding
architecture header via a symbolic link.
An obvious drawback is the increase in complexity with macros, and
headers. It also caused a split of architecture definitions between
md-unwind-def.h (types definitions used in unwind-dw2.h) and
md-unwind.h (local types definitions and handlers implementations).
The naming of md-unwind.h with .h extension is a bit misleading as
the file is only included in the middle of unwind-dw2.c. Changing
this naming would require modification of others backends, which I
prefered to abstain from. Overall the benefits are worth the added
complexity from my perspective.
libgcc/ChangeLog:
* Makefile.in: New target for symbolic link to md-unwind-def.h
* config.host: New parameter md_unwind_def_header. Set it to

This patch is only a refactoring of the existing implementation
of PAuth and returned-address signing. The existing behavior is
preserved.
_Unwind_FrameState already contains several CIE and FDE information
(see the attributes below the comment "The information we care
about from the CIE/FDE" in libgcc/unwind-dw2.h).
The patch aims at moving the information from DWARF CIE (signing
key stored in the augmentation string) and FDE (the used signing
method) into _Unwind_FrameState along the already-stored CIE and
FDE information.
Note: those information have to be saved in frame_state_reg_info
instead of _Unwind_FrameState as they need to be savable by
DW_CFA_remember_state and restorable by DW_CFA_restore_state, that
both rely on the attribute "prev".
Those new information in _Unwind_FrameState simplifies the look-up
of the signing key when the return address is demangled. It also
allows future signing methods to be easily added.
_Unwind_FrameState is not a part of the public API of libunwind,
so the change is backward compatible.
A new architecture-specific handler MD_ARCH_EXTENSION_FRAME_INIT
allows to reset values (if needed) in the frame state and unwind
context before changing the frame state to the caller context.
A new architecture-specific handler MD_ARCH_EXTENSION_CIE_AUG_HANDLER
isolates the architecture-specific augmentation strings in AArch64
backend, and allows others architectures to reuse augmentation
strings that would have clashed with AArch64 DWARF extensions.
aarch64_demangle_return_addr, DW_CFA_AARCH64_negate_ra_state and
DW_CFA_val_expression cases in libgcc/unwind-dw2-execute_cfa.h
were documented to clarify where the value of the RA state register
is stored (FS and CONTEXT respectively).
