f78f73cbd2 Remove bt-load.c 
bt-load.c has AFAIK been dead code since the removal of the SH5 port
in 2016.  I have a patch series that would need to update the liveness
tracking in a nontrivial way, so it seemed better to remove the pass
rather than install an untested and probably bogus change.

d0e086ae4f Minor std::to_chars optimisation for base 10 
__to_chars_10_impl is quite fast. According to the IACA the main loop
takes only 6.0 cycles, the whole function with one iteration takes
10.0 cycles. Replacing the __first[pos] and __first[pos - 1] with
__first[0] and __first[1] drops the function time to 7.53 cycles.

	* include/bits/charconv.h (__detail::__to_chars_10_impl): Replace
	final offsets with constants.

27dada7d06 Improve constraints for std::span constructors 
This patch simplifies the constraints on the constructors from arrays by
removing the redundant checks that element_type and value_type are
convertible to element_type. The incorrect uses of __adl_data in those
constructors are removed as well (they should use std::data not
std::ranges::data, and the former doesn't use ADL).

The range/container constructors are now constrained to exclude all
specializations of std::span, not just the current instantiation. The
range constructor now also checks s subset of the contiguous_range
requirements.

All relevant constructor constraints now use the _Require helper in
order to short circuit and avoid unnecessary instantiations after the
first failed constraint.

A new constructor supports initialization from different specializations
of std::span<OtherType, OtherExtent>, as specified in the C++20 draft.

	* include/bits/range_access.h (__adl_to_address): Remove.
	* include/std/span (__is_base_derived_safe_convertible_v): Replace
	with span::__is_compatible.
	(__is_std_array_v): Replace with __is_std_array class template and
	partial specializations.
	(__is_std_array, __is_std_span): New class templates and partial
	specializations.
	(span::__is_compatible): New alias template for SFINAE constraints.
	(span::span(element_type (&)[N])): Remove redundant constraints. Do
	not use __adl_data to obtain a pointer.
	(span::span(array<value_type, N>&)): Likewise.
	(span::span(const array<value_type, N>&)): Likewise.
	[_GLIBCXX_P1394] (span::iter_reference_t, span::iterator_t)
	(span::iter_value_t, span::derived_from): New alias templates for
	SFINAE constraints, until the equivalents are supported in <concepts>
	and <iterator>.
	[_GLIBCXX_P1394] (span::__is_compatible_iterator): New alias template
	for SFINAE constraints.

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.
	* configure.ac: Support for bpf-*-* targets.
	* configure: Regenerate.

contrib/ChangeLog:

	* config-list.mk (LIST): Disable go in bpf-*-* targets.

gcc/ChangeLog:

	(eBPF Options): New section.
	* doc/extend.texi (BPF Built-in Functions): Likewise.

a5362c6aea testsuite: new require effective target indirect_calls 
This patch adds a new dg_require_effective_target procedure to the
testsuite infrastructure: indirect_calls.  This new function tells
whether a target supports calls to non-constant call targets.
    
This patch also annotates the tests in the gcc.c-torture testuite that
require support for indirect calls.

            indirect_calls.

36ec3f57d3 RISC-V: Fix bad insn splits with paradoxical subregs. 
Shifting by more than the size of a SUBREG_REG doesn't work, so we either
need to disable splits if an input is paradoxical, or else we need to
generate a clean temporary for intermediate results.

Jakub wrote the first version of this patch, so gets primary credit for it.
