91dfef9610 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.

This re-enables -msave-restore for shared libraries, and uses the

f0efd92502 [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);

179c7ef523 [Darwin] Some TLC for older Darwin versions.
The library handling and some of the options for creating the crts for
the older PPC Darwin versions had bit-rotted somewhat.  This adjusts the
build criteria for the crts to avoid newer ld64 versions warnings about
mismatches in build and object versions.

Added to some of the comments that it's documented why the specs are as
they are.

34a4a9c2b5 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.

ef5eb79dfd 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.
