Iain Sandoe 476036b35c libsanitizer, Darwin, Bootstrap : Fix bootstrap on Darwin <= 15.
The latest upstream merge for libsanitizer introduces code that makes
use of some macro values that are not available in SDKs for versions
of Darwin <= 15 (macOS 10.11).

Add definitions for these where they are not present.

libsanitizer/ChangeLog:

	* sanitizer_common/sanitizer_mac.h: Ensure that TARGET_OS_
	macros are defined where the macOS SDK does not contain
	them.
	(TARGET_OS_OSX, TARGET_OS_IOS, TARGET_OS_TV, TARGET_OS_WATCH):
	Define where needed.

Rainer Orth 6805c1c6a6 libsanitizer: Fix GetPcSpBp determination of SP on 32-bit Solaris/x86
The latest Solaris 11.4/x86 update uncovered a libsanitizer bug that
caused one test to FAIL for 32-bit:

Libsanitizer: merge from master.
Merged from revision b638b63b99d66786cb37336292604a2ae3490cfd.

The patch successfully bootstraps on x86_64-linux-gnu and
ppc64le-linux-gnu. I also tested ppc64-linux-gnu that exposed:
https://reviews.llvm.org/D80864 (which is fixed on master).

Abidiff looks happy and I made UBSAN and ASAN bootstrap on
x86_64-linux-gnu.

I'm planning to do merge from master twice a year, once now and
next time short before stage1 closes.

I am going to install the patches as merge from master is obvious
and I haven't made anything special.

Iain Sandoe 63cc547f6d Darwin, libsanitizer: Adjust minimum supported Darwin version (PR93731).
The current imported libsanitizer code produces kernel panics for
Darwin 11 (macOS 10.7) and is unsupported for earlier versions already.

It is not clear if the current sources are even intended to be supported
on Darwin 11, so this patch causes the default to be build without
sanitizers for Darwin <= 11.

Maciej W. Rozycki e8e66971cd Add `--with-toolexeclibdir=' configuration option
Provide means, in the form of a `--with-toolexeclibdir=' configuration
option, to override the default installation directory for target
libraries, otherwise known as $toolexeclibdir.  This is so that it is
possible to get newly-built libraries, particularly the shared ones,
installed in a common place, so that they can be readily used by the
target system as their host libraries, possibly over NFS, without a need
to manually copy them over from the currently hardcoded location they
would otherwise be installed in.

In the presence of the `--enable-version-specific-runtime-libs' option
and for configurations building native GCC the option is ignored.

Tamar Christina 761a3a95ee Arm: Fix arm libsanitizer bootstrap failure
Glibc has recently introduced changed to the mode field in ipc_perm
in commit 2f959dfe849e0646e27403f2e4091536496ac0f0. For Arm this
means that the mode field no longer has the same size.

This causes an assert failure against libsanitizer's internal copy
of ipc_perm.  Since this change can't be easily detected I am adding
arm to the list of targets that are excluded from this check.  libsanitizer
doesn't use this field (and others, it in fact uses only 1 field) so this check
can be ignored.

Padding bits were used by glibc when the field was changed so sizeof and offsets
of the remaining fields should be the same.

libsanitizer/ChangeLog:

	PR sanitizer/92154
	* sanitizer_common/sanitizer_platform_limits_posix.cpp (defined):
	Cherry-pick compiler-rt revision r375220.

Christophe Lyon 45d53c679a [ARM/FDPIC v6 03/24] [ARM] FDPIC: Force FDPIC related options unless -mno-fdpic is provided
In FDPIC mode, we set -fPIE unless the user provides -fno-PIE, -fpie,
-fPIC or -fpic: indeed FDPIC code is PIC, but we want to generate code
for executables rather than shared libraries by default.

We also make sure to use the --fdpic assembler option, and select the
appropriate linker emulation.

At link time, we also default to -pie, unless we are generating a
shared library or a relocatable file (-r). Note that static link is
not supported as it requires specifying the dynamic linker because the
executable still has to relocate itself at startup.

We also force 'now' binding since lazy binding is not supported.

We should also apply the same behavior for -Wl,-Ur as for -r, but I
couldn't find how to describe that in the specs fragment.
