[ARM/FDPIC v6 13/24] [ARM] FDPIC: Force LSB bit for PC in Cortex-M architecture
...
Without this, when we are unwinding across a signal frame we can jump
to an even address which leads to an exception.
This is needed in __gnu_persnality_sigframe_fdpic() when restoring the
PC from the signal frame since the PC saved by the kernel has the LSB
bit set to zero.

[ARM/FDPIC v6 06/24] [ARM] FDPIC: Add support for c++ exceptions
...
The main difference with existing support is that function addresses
are function descriptor addresses instead. This means that all code
dealing with function pointers now has to cope with function
descriptors instead.
For the same reason, Linux kernel helpers can no longer be called by
dereferencing their address, so we implement wrappers that directly
call the kernel helpers.
When restoring a function address, we also have to restore the FDPIC
register value (r9).

[ARM/FDPIC v6 02/24] [ARM] FDPIC: Handle arm*-*-uclinuxfdpiceabi in configure scripts
...
The new arm-uclinuxfdpiceabi target behaves pretty much like
arm-linux-gnueabi. In order to enable the same set of features, we
have to update several configure scripts that generally match targets
like *-*-linux*: in most places, we add *-uclinux* where there is
already *-linux*, or uclinux* when there is already linux*.
In gcc/config.gcc and libgcc/config.host we use *-*-uclinuxfdpiceabi
because there is already a different behaviour for *-*uclinux* target.
In libtool.m4, we use uclinuxfdpiceabi in cases where ELF shared
libraries support is required, as uclinux does not guarantee that.

GCC port for eBPF
...
This patch series introduces a port of GCC to eBPF, which is a virtual
machine that resides in the Linux kernel. Initially intended for
user-level packet capture and filtering, eBPF is nowadays generalized
to serve as a general-purpose infrastructure also for non-networking
purposes.
The binutils support is already upstream. See
https://sourceware.org/ml/binutils/2019-05/msg00306.html .
ChangeLog:
* MAINTAINERS: Add myself as the maintainer of the eBPF port.
Remove myself from Write After Approval section.

[Arm][CMSE]Add warn_unused_return attribute to cmse functions
...
At present it is possible to call the CMSE functions for checking
addresses (such as cmse_check_address_range) and forget to check/use
the return value. This patch makes the interfaces more robust against
programmer error by marking these functions with the warn_unused_result
attribute. With this set, any use of these functions that does not use
the result will produce a warning.
This produces a warning on default warn levels when the result of the
cmse functions is not used.
For the following function:
void foo()
{
int *data;
cmse_check_address_range((int*)data, 0, 0);
}
The following warning is emitted:
warning: ignoring return value of 'cmse_check_address_range' declared
with attribute 'warn_unused_result' [-Wunused-result]
6 | cmse_check_address_range((int*)data, 0, 0);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Darwin, PowerPC, libgcc - Ensure unwinder is built with altivec enabled.
...
When libgcc is built on Darwin, it is usually built for the earliest potential
target (Darwin8, 10.4). Build for that revision default to assuming that the
processor might be G3 (without vector ops) and there is an outlined function
used for save/restore that checks whether the processor is G3 or G4+ at run-
time. However, the unwinder itself needs to be built with the assumption of
vector usage so that the relevant outlined functions are called.

darwin, powerpc - set .machine in an asm file.
...
The asm file fails to build if we use a modern assembler
which checks that the machine is consistent with the
filetype. Fixed by adjusting in a similar manner to
other assembler.
