AArch64: Have empty HWCAPs string ignored during native feature detection · 29c6debc

This patch makes the feature detection code for AArch64 GCC not add features
automatically when the feature had no hwcaps string to match against.

This means that -mcpu=native no longer adds feature flags such as +profile.
The behavior wasn't noticed before because at the time +profile was added a bug
was preventing any feature bits from being added by native detections.

The loop has also been changed as Jakub specified in order to avoid a memory
leak that was present in the existing code and to be slightly more efficient.

	PR target/88530
	* config/aarch64/aarch64-option-extensions.def: Document it.
	* config/aarch64/driver-aarch64.c (host_detect_local_cpu): Skip feature

re PR go/89172 (FAIL: runtime/pprof) · cba8a572

	PR go/89172
    internal/cpu, runtime, runtime/pprof: handle function descriptors
    
    When using PPC64 ELF ABI v1 a function address is not a PC, but is the
    address of a function descriptor.  The first field in the function
    descriptor is the actual PC (see
    http://refspecs.linuxfoundation.org/ELF/ppc64/PPC-elf64abi.html#FUNC-DES).
    The libbacktrace library knows about this, and libgo uses actual PC
    values consistently except for the helper function funcPC that appears
    in both runtime and runtime/pprof.
    
    This patch fixes funcPC by recording, in the internal/cpu package,
    whether function descriptors are being used.  We have to check for
    function descriptors using a C compiler check, because GCC can be
    configured using --with-abi to select the ELF ABI to use.
    
    Fixes https://gcc.gnu.org/PR89172

PR c++/86969 - ICE with constexpr if and recursive generic lambdas. · e6df04c1

Here, the problem was that extract_local_specs wasn't seeing that we use
'self' inside the lambda in the else of the inner constexpr if, because we
don't walk into lambda bodies and we didn't capture it in the lambda because
'self' is still dependent.  Marek recently changed process_outer_var_ref to
do more implicit capture in templates; this example shows that we should
always capture non-packs, so that we can continue to not walk into lambda
bodies.  We do walk into lambda bodies for pack expansions, so we can delay
deciding whether we're capturing a single element or the entire pack.

Immediately capturing a VLA means we need to create a dependent VLA capture
type, and not in the context of the lambda op(), since trying to look up the
instantiation of the op() while we're substituting into the capture list
would crash.  So I force TYPE_CONTEXT and the binding level out to the
enclosing function before pushtag, avoid adding a TAG_DEFN, and instead
force the type to be complete in tsubst_lambda_expr.

	* semantics.c (process_outer_var_ref): Do capture dependent vars.
	* class.c (finish_struct): Only add TAG_DEFN if T is in
	current_function_decl.
	* lambda.c (vla_capture_type): Force the capture type out into the
	lambda's enclosing function.
	(add_capture): Pass in the lambda.
	* pt.c (tsubst_lambda_expr): complete_type a VLA capture type.

PR libstdc++/89466 avoid slow xsltproc command in configure · a4395a84

Certain broken versions of xsltproc ignore the --nonet option and will
attempt to fetch the docbook stylesheet from the WWW when it isn't in
the local XML catalog.

This patch checks for the local stylesheet directory first, and doesn't
use xsltproc if no local stylesheets are found. Checking for the local
directory is done using xmlcatalog if available, only checking the
hardcoded list of directories if xmlcatalog fails. The right directory
for Suse is added to the hardcoded list.

This should avoid doing an xsltproc check that would need to download
the stylesheet, so no network connection is made even if a broken
xsltproc is present.

	* acinclude.m4 (GLIBCXX_CONFIGURE_DOCBOOK): Reorder check for local
