C++: Fix ICE when adding overloaded operator via using_decl (PR c++/88699) · b9e03679

PR c++/88699 reports an ICE within this assertion in add_method:

  gcc_assert (!current_fns || !DECL_DESTRUCTOR_P (method));

when adding an overloaded operator to a class via a using_decl, due to
DECL_DESTRUCTOR_P requiring a FUNCTION_DECL, but "method" being a
USING_DECL.

This patch weakens the assertion to avoid testing DECL_DESTRUCTOR_P
for the case where "via_using" is true, fixing the ICE.

Ignore LLVM's blank lines. · b50002c4

The GCN toolchain must use the LLVM assembler and linker because there's no
binutils port.  The LLVM tools do not have the same diagnostic style as
binutils, so the "blank line(s) in output" tests are inappropriate (and very
noisy).

The LLVM tools also have different command line options, so it's not possible
to autodetect object formats in the same way.

This patch addresses both issues.

Testsuite: GCN is always PIE. · 90eb9be6

The GCN/HSA loader ignores the load address and uses a random location, so we

Add dg-require-effective-target exceptions · 3f21b8e3

There are a number of tests that fail because they assume that exceptions are
available, but GCN does not support them, yet.

This patch adds "dg-require-effective-target exceptions" in all the affected
tests.  There's probably an automatic way to test for exceptions, but the
current implementation simply says that AMD GCN does not support them.  This
should ensure that no other targets are affected by the change.

GCN back-end config · 7431c1a1

This patch contains the configuration adjustments needed to enable the GCN
back-end.

The new configure check for dlopen is required to allow building the new
gcn-run tool.  This tool uses libdl to load the HSA runtime libraries, which
are required to run programs on the GPU.  The tool is disabled if libdl is not
available.

GCN back-end code · 5326695a

This patch contains the major part of the GCN back-end.  The machine
description has been broken out to avoid the mailing list size limit.

The back-end contains various bits that support OpenACC and OpenMP, but the
middle-end and libgomp patches are missing, as is mkoffload.  I include them
here because they're harmless and carving up the files seems like unnecessary
effort.  The remaining offload support will be posted at a later date.

The gcn-run.c is a separate tool that can run a GCN program on a GPU using
the ROCm drivers and HSA runtime libraries.
