Olivier Hainque 9a835ba4c0 Introduce support for vxworks7r2 on x86 and x86_64
This change extends the VxWorks support on intel CPUs to
VxWorks7r2 for x86_64 as well as x86, with a "mcmodel=large"
additional multilib for the 64bit configuration.

The support for fPIC is not functional yet for this model,
so we just don't add the corresponding multilib.

We extend the range of CPU families handled by TARGET_OS_CPP_BUILTINS,
accounting for the fact that archs older than PENTIUM4 are
not supported (any more) by VxWorks 7.

As we did for powerpc, we leverage VX_CPU_PREFIX to emit different
forms of definitions for different families of VxWorks as the system
headers's expectations has evolved between Vx 5, 6 and 7.

Douglas Rupp 1786798090 Introduce vxworks7r2 support for ppc and ppc64
This change introduces support for the most recent versions
of VxWorks on PowerPC targets, for both 32 and 64 bit thanks
to a bi-arch setup.

The system compilers are essentially configured as Linux
toolchains with only a few specificities and we replicate
that model here.

The most visible specificities are the use of secureplt by
default, the pre-definition of some macros that the system
headers still rely on (_VX_CPU and _VX_CPU_FAMILY, for example),
and of course some variations related to the so VxWorks typical
kernel vs RTP mode distinction.

In addition to the introduction of config.gcc and libgcc
configuration chunks, much inspired by the linux ones, the
change

- Reworks rs6000/vxworks.h file to feature bits common to the
  Vx6 and Vx7 port then a separate section for each, where the
  Vx7 part is very short as we rely on the Linux definitions
  for most things.

- Adjusts the CPU macro predefinitions in CPP_SPEC to resort
  to "_VX_CPU" instead of "CPU" for Vx7, to better match the
  more recent system headers expectations,

- Adds a cpu definition case for e6500.

- Changes to the use SUB3TARGET_OVERRIDE_OPTIONS instead of
  SUBSUBTARGET_OVERRIDE_OPTIONS for specifics, so we don't
  override the Linux's version of the latter for vx7.

	* config/rs6000/vxworks.h: Rework to handle VxWorks7.
	Refactor as common bits + vx6 vs vx7 ones. For the
	latter, rely essentially on the Linux configuration
	and adjust CPU to _VX_CPU in CPP_SPEC. Add a case
	for e6500. Use SUB3TARGET_OVERRIDE_OPTIONS for specifics
	to preserve the Linux SUBSUBTARGET_OVERRIDE_OPTIONS
	for vx7.

David Edelsohn 47ddb895df aix: Add GCC64 configuration and FAT target libraries.
This patch adds the ability to configure GCC on AIX to build as a
64 bit application and to build target libraries "FAT" libraries in both
32 bit and 64 bit mode.

The patch adds makefile fragment hooks to target libraries that allows
them to include target-specific rules.  The target specific rules for
AIX place both 32 bit and 64 bit objects and shared objects
in archives at the top-level, not multilib subdirectories.  The
multilibs are built in subdirectories, but must be combined during the
last parts of the target library build process.  Because of the way
that GCC bootstrap works, the libraries must be combined during the
multiple stages of GCC bootstrap, not solely when installed in the
final destination, so the libraries are correct at the end of
each target library build stage, not solely an install recipe.

Sandra Loosemore 2d33dcfe9f nios2: Support for GOT-relative DW_EH_PE_datarel encoding.
On nios2-linux-gnu, there has been a long-standing bug in C++ exception
handling that sometimes resulted in link errors like

../nios2-linux-gnu/bin/ld: FDE encoding in /tmp/cccfpQ2l.o(.eh_frame) prevents .eh_frame_hdr table being created

when building some shared libraries or PIE executables.  The root of
the problem is that GCC was incorrectly emitting an absolute encoding
in EH tables for PIC.  This patch changes it to use either
DW_EH_PE_indirect (for global) or DW_EH_PE_datarel (for local), and
fixes libgcc so it can find the address of the GOT as the base address
for DW_EH_PE_datarel.

Complicating matters somewhat, GAS was missing support for
%gotoff(symbol) relocation syntax.  I have just pushed a fix for that,
but I've added a configure check to test for presence of the binutils
support and fall back to the current absolute encoding (which works
most of the time) if it is not available.  Once the fix makes it into
an official binutils release it might be appropriate to make this
error out instead.

Since this is a wrong-code bug and affects only nios2 target, I think
this is appropriate for Stage 4.  I regression-tested on both
nios2-linux-gnu and nios2-elf, with and without the binutils support
present, before committing this.

Szabolcs Nagy 3d3a96a26e musl: Don't use gthr weak refs in libgcc PR91737
The gthr weak reference based single thread detection is unsafe with
static linking and in case of dynamic linking it's ineffective on musl
since pthread symbols are defined in libc.so.

(Ideally this should be fixed for all targets, since glibc plans to move
libpthread.so into libc.so too and users want to static link to pthread
without --whole-archive: PR87189.)

For now we have to explicitly opt out from the broken behaviour in the
config machinery of each target lib and libgcc was previously missed.

Christophe Lyon b1e21e5a5d [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.

Jose E. Marchesi 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.

Iain Sandoe 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.
