This patch removes the generation of HSAIL from the compiler, the HSA
offloading plugin from libgomp and the associated testsuite tests and
infrastructure bits from the respective testsuites.
Apart from removal of the obvious files, I removed bits that I found
by searching for HSA related terms and by re-tracing my steps and
looking at the patches that introduced HSA in the first place. I did
not remove everything these patches brought in, for example:
- the mechanism to pass offload-target specific info from the application to
the offloading plugin - but the same mechanism is also used to
communicate number of teams and the thread limit to all offload targets.
- run_func hook in gomp_device_descr stays too, although now it is
not used. If some future offload target would like the ability to
refuse to offload some functions, it can use it. It is easy to
remove as a follow-up if it is considered clutter, though.
- configure options --with-hsa-runtime=PATH, -with-hsa-runtime-include=PATH
and --with-hsa-runtime-lib=PATH rmeain because GCN uses them too.
- Surprisingly, GOMP_TARGET_ARG_HSA_KERNEL_ATTRIBUTES (a constant
from gomp-constants.h) appears in the source of the amdgcn libgomp
plugin, although I tend to think that code path is not ever used
and this patch certainly removes it from the compiler.
Nevertheless, it seems it has potential value beyond HSAIL and so
I've kept it, it can of course always be easily removed in the
future of GCN folk abandon it too.
- I assume constants OFFLOAD_TARGET_TYPE_HSA and GOMP_DEVICE_HSA
need to stay indefinitely too just so that no future offload
target picks that number.
- I have kept dg-require-effective-target
offload_device_nonshared_as requirement of thests which have it.
It is quite probable I missed some small HSA artifacts but those
should be easy to remove later as we find them.

In 2012 e2769e908a915ebbc/r192344, I added the following lines, that I
now delete. I've changed my mind: ELF-related targets based on gas,
that support only static linking, have .hidden "for free", regardless
of the visibility of the hidden object in the linked executable. No
regressions for mmix-knuth-mmixware and "fixes":
FAIL: gcc.dg/torture/pr94947-1.c -O2 -flto -fuse-linker-plugin -fno-fat-lto-objects (test for excess errors)
Excess errors:
lto1: warning: visibility attribute not supported in this configuration; ignored [-Wattributes]
...a warning which is emitted for "all" LTO tests (of which most have
warnings filtered out); LTO "thinks" all supported targets have
.hidden support.

* configure.ac (out-of-tree linker .hidden support): Don't turn off
for mmix-knuth-mmixware.

Previously I had AX_CXX_COMPILE_STDCXX in the gcc directory configure, which
added -std=c++11 to CXX if needed, but then CXX is overridden from the
toplevel directory, so it didn't have the desired effect. Fixed by moving
the check to the toplevel. Currently it is only used when building GCC
without bootstrapping; other packages that share the toplevel directory
can adjust the condition if they also want to require C++11 support.

I've recently tested i386-pc-solaris2.11 bootstrap on Solaris 11/x86
with only the bundled tools (using /usr/gnu/bin/as from binutils 2.30 in
this case). It failed compiling libgo/runtime/proc.c, creating invalid
assembly:
proc.s: Assembler messages:
proc.s:2092: Error: junk at end of line, first unrecognized character is `*'
.globl __emutls_v.*runtime.g
and several more errors. This is completely unexpected since Solaris
does support TLS. It turned out that 32-bit TLS detection in
gcc/configure had failed:
configure:25145: checking assembler for thread-local storage support
configure:25158: /usr/gnu/bin/as --fatal-warnings -o conftest.o conftest.s >&5
conftest.s: Assembler messages:
conftest.s:6: Error: relocated field and relocation type differ in signedness
conftest.s:7: Error: @TLSLDM reloc is not supported with 64-bit output format
conftest.s:7: Error: junk `@tlsldm' after expression
which isn't unexpected given that the bundled gas has been configured
for x86_64-pc-solaris2.11, i.e. 64-bit-default.
This is easily fixed by explicitly passing --32 for the 32-bit case,
matching what is done for the 64-bit test.
Tested on i386-pc-solaris2.11 with 32-bit-default and 64-bit-default gas
as well as with /usr/bin/as, always correctly detecting TLS support.
* configure.ac <i[34567]86-*-*>: Add --32 to tls_as_opt on Solaris.

The real problem of course is elsewhere.

PR 92830 reports that we always use "gcc/Warning-Options.html" when we
emit escaped documentation URLs when printing "[-Wname-of-option]" for
a warning.
This page is wrong for most Fortran warnings, and for analyzer warnings.
I considered various schemes involving adding extra tags to the .opt
format to capture where options are documented, but for now this patch
fixes the issue by introducing some special-casing logic.
It only fixes the URLs for warning options, not for other command-line
options, but those are the only options for which get_option_url is
currently called.

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.

gcc: Add new configure options to allow static libraries to be selected
contains a couple of issues. First I failed to correctly regenerate
all of the configure files it should have done. Second, there was a
mistake in lib-link.m4, one of the conditions didn't use pure sh
syntax, I wrote this:
if x$lib_type = xauto || x$lib_type = xshared; then
When I should have written this:
if test "x$lib_type" = "xauto" || test "x$lib_type" = "xshared"; then
These issues were raised on the mailing list in these messages:

The FTP protocol is getting long in the tooth, and we should emphasize
HTTPS where that is available. This patch changes various gcc.gnu.org
URL's to instead use HTTPS.
For instance, kernel.org shut down FTP access in 2017, with the
explanation:
- The protocol is inefficient and requires adding awkward kludges to
firewalls and load-balancing daemons
- FTP servers have no support for caching or accelerators, which has
significant performance impacts
- Most software implementations have stagnated and see infrequent
updates

This patch removes !TARGET_TLS_MARKERS support. -mtls-markers (and
-mno-tls-markers) disappear as valid options too, because I figure

The 'gcc/configure' script sources all 'gcc/*/config-lang.in' files, but fails
to emit such dependency information into the build machinery. That means,
currently, when something gets changed in a 'gcc/*/config-lang.in' file, this
is not noticed, and doesn't propagate through the build machinery.
Handling of configure fragments is modelled in the same way as it already
exists for Makefile fragments.

Configuring GCC for obsolete targets works as long as build = host.
When it isn't, --enable-obsolete is not passed down to the additional
build configure started by gcc/configure, used to generate
auto-build.h. The build configure fails and we end up without a
auto-build.h, but the host configure proceeds, so we only get a fatal
failure much later, when make realizes auto-build.h is not there and
there's no rule to create it.
This patch gets the host configure to fail when the build configure
does, leaving the temporary build configure dir behind for
investigation. It also arranges for --eanble-obsolete to be passed
down to the build configure.
Alas, the latter triggered a warning in the build configure because
--enable-obsolete is not a recognized configure option. That's not
reported in the host configure because of the
--disable-option-checking passed by the top-level configure, so I
arranged for that to be passed down to the build configure as well.
Finally, since my initial suspicion when investigating this failure
was that auto-build.h had been removed after configuration and there
was no rule to rebuild it, I'm adding rules to gcc/Makefile to get it
created or updated as needed. Since it is configure that creates it,
as run by e.g. config.status --recheck, and config.status is created
after auto-build.h, I've made config.status depend on auto-build.h,
and added a dummy rule to create auto-build.h. This would normally
not be enough to create a header when needed, but since Makefile
depends on config.status, and make first updates Makefile, it ends up
working, as long as nothing else that Makefile depends on requires
auto-build.h but not config.status. The config.status dependency and
the auto-build.h rule are only enabled in the cases in which
auto-build.h is actually used, namely when build != host.

This patch uses the support for pretty-printing escaped URLs added in
the previous patch (PR 87488) so that in a sufficiently capable terminal
the [-Wname-of-option] emitted at the end of each diagnostic becomes a
hyperlink to the documentation for that option on the GCC website.
I've tested it with Fedora 30's GNOME Terminal (3.32.2 with VTE 0.56.3);
the option text is printed with a dotted underline, hovering shows the
URL, and on right-clicking it offers menu items to visit/copy the URL.

For some reason, presumably historical, the `install-gnatlib' target for
the default multilib is invoked twice, once via the `ada.install-common'
target in `gcc/ada/gcc-interface/Make-lang.in' invoked from gcc/ and
again via the `install-libada' target in libada/.
Apart from doing the same twice this is actually harmful in sufficiently
parallelized `make' invocation, as the removal of old files performed
within the `install-gnatlib' recipe in the former case actually races
with the installation of new files done in the latter case, causing the
recipe to fail and abort, however non-fatally, having not completed the
installation of all the built files needed for the newly-built compiler
to work correctly.
This can be observed with a native `x86_64-linux-gnu' bootstrap:
make[4]: Entering directory '.../gcc/ada'
rm -rf .../lib/gcc/x86_64-linux-gnu/10.0.0/adalib
rm: cannot remove '.../lib/gcc/x86_64-linux-gnu/10.0.0/adalib': Directory not empty
make[4]: *** [gcc-interface/Makefile:512: install-gnatlib] Error 1
make[4]: Leaving directory '.../gcc/ada'
make[3]: *** [.../gcc/ada/gcc-interface/Make-lang.in:853: install-gnatlib] Error 2
make[2]: [.../gcc/ada/gcc-interface/Make-lang.in:829: ada.install-common] Error 2 (ignored)
which then causes missing files to be reported when an attempt is made
to use the newly-installed non-functional compiler to build a
`riscv-linux-gnu' cross-compiler:
(cd ada/bldtools/sinfo; gnatmake -q xsinfo ; ./xsinfo sinfo.h )
error: "ada.ali" not found, "ada.ads" must be compiled
error: "s-memory.ali" not found, "s-memory.adb" must be compiled
gnatmake: *** bind failed.
/bin/sh: ./xsinfo: No such file or directory
make[2]: *** [.../gcc/ada/Make-generated.in:45: ada/sinfo.h] Error 127
make[2]: Leaving directory '.../gcc'
make[1]: *** [Makefile:4369: all-gcc] Error 2
make[1]: Leaving directory '...'
make: *** [Makefile:965: all] Error 2
Depending on timing `.../lib/gcc/x86_64-linux-gnu/10.0.0/adainclude' may
cause an installation failure instead and the resulting compiler may be
non-functional in a different way.
Only invoke `install-gnatlib' from within gcc/ then if a legacy build
process is being used with libada disabled and gnatlib built manually
with `make -C gcc gnatlib'.

The recent trunk r270914 for PR89221 "--enable-frame-pointer does not work as
intended" fixed a scripting defect in the x86 '--enable-frame-pointer'
handling.
This has the side effect that, for example, for '--target=i686-gnu' this is now
enabled by default: 'USE_IX86_FRAME_POINTER=1' is added to 'tm_defines'. Given
that it's highly unlikely that anyone would now suddenly want
'--enable-frame-pointer' as the default for any kind of GNU system, I'm
changing the default back for GNU systems, to match that of a 'target_os' of
'linux* | darwin[8912]*'.
