[Darwin, machopic] Preparatory patches.
This is a combined set of 5 patches that allows us to fix PRs 65342
and 67183.
276924 Make machopic_finish() static.
276767 Set a SYMBOL flag for indirections.
We are able to treat these specially where needed in legitimate address
tests (specifically, they are guaranteed to be pointer-aligned).
276708 Compute and cache indirection rules.
This caches a check for the requirement to indirect a symbol in the Darwin
ABI, and uses it where needed. We also ensure that we place the indirection
pointers into the non-lazy symbol pointers section. Other placements have
occurred with various platform toolchains - but these seem to have been
unintentional so we match current platform toolchains.
276675 Consider visibility in indirections.
For weak, hidden vars the indirection should just be as normal, that
is that the indirections for such symbols should appear in the non-lazy
symbol pointers table, not in the .data section.
276674 Initial tidy of Mach-O symbol handling.
We want to improve the detection and caching of symbol-properties
so that (a) we can make the compiler's output match the platform
norms (b) we can improve efficiency by checking flags instead of
inspecting strings. (c) The fix for PR71767 was a largish hammer
and we want to reduce the number of symbols that are made linker-
visible.
This first patch is largely typographical changes with no functional
difference intended:
- Tries to ensure that there's no overlap between the symbols used in
the Mach-O case and those declared in the i386 or rs6000 port trees.
- Some improvement to comments.
- Makes the naming of the symbol flags consistent with other uses.
- Provides a predicate macro for each use.

Darwin's linker doesn't like text section relocations (they require special

[Darwin] Pick up SDKROOT as the sysroot fallback.
For compatibility with xcrun and the behaviour of the clang driver, make use
of the setting of the SDKROOT environment variable when it is available.
This applies to both finding headers and libraries (i.e. it is also passed to
ld64).
Priority:
1. User's command-line specified --sysroot= or -isysroot.
2. The SDKROOT variable when set, and validated.
3. Any sysroot provided by --with-sysroot= configuration parameter.
SDKROOT is checked thus:
1. Presence.
2. That it starts with / (i.e. 'absolute').
3. That it is not / only (since that's the default).
4. That it is readable by the process executing the driver.
This is pretty much the same rule set as used by the clang driver.
NOTE: (3) might turn out to be overly restrictive in the case that we
have configured with --with-sysroot= and then we want to run on a system
with an installation of the headers/libraries in /. We can revisit this
if that turns out to be an important use-case.
So one can do:
xcrun --sdk macosx /path/to/gcc ....
and that provides the SDK path as the sysroot to GCC as expected.
CAVEAT: An unfortunate effect of the fact that gcc (and g++) are
executables in the Xcode installation, which are found ahead of any such
named in the $PATH

[Darwin, specs] Fix driver handling of PIE options.
pie, no-pie and rdynamic are driver options, we can process them in the
relevant place and drop them once dealt with. There's no need to generate
a new header to process the no_compact_unwind which is applied on the

Support for the -pie, -no_pie and -no_compact_unwind options should ideally
be checked at configure time, however the status quo is to assert that linkers
capable of targeting the relevant systems support these options (i.e. we trust
that the user doesn't attempt to configure inappropriately).
TODO: check the availability of the linker opts in configure rather than
trusting to the user.

This patch fixes a problem with the thumb1 prologue code where the link
register could be unconditionally used as a scratch register even if the
return value was still live at the end of the prologue.
Additionally, the patch improves the code generated when we are not
using many low call-saved registers to make use of any unused call
clobbered registers to help with the saving of high registers that
cannot be pushed directly (quite rare in normal code as the register
allocator correctly prefers low registers).

Armv6 has support for unaligned accesses to memory. However, the
thumb1 code patterns were trying to use the 32-bit code constraints.
One failure mode from this was that the patterns are designed to be
compatible with conditional execution and this was then causing an
assert in the compiler.
The unaligned_loadhis pattern is only used for expanding extv, which
in turn is only enabled for systems supporting thumb2. Given that
there is no simple expansion for a thumb1 sign-extending load (the
instruction has no immediate offset form and requires two registers in
the address) it seems simpler to just disable this for thumb1.
Fixed thusly:

Since we cannot parse the current NeXT headers, because of PR90709 and its

In order to restore the usefulness of the testsuite, we are going add headers
without the modern syntax elements that trigger the bug, and use these for
test runs on newer Darwin.
The headers are imported from GNUStep, with some local modifications to make
sure that __BLOCKS__ is honoured as a gate for Apple-style blocks closures.
CF-CFString.h, F-NS*.h are proxy headers that use the installed CoreFoundation
or Foundation headers on systems <= Darwin12 and the GNUStep headers for newer.
Use the CF-CFString.h, F-NS*.h proxy headers where needed in the objective-c
testsuite. Make minor adjustments to tests as required, providing that those
do not alter the test intent.

[Darwin, testsuite] Adjust two tests that fail on newer OS versions.
Newer OS versions (10.14+) do not provide some of the CRTs that are used
for older ones (e.g. 10.5), and thus link tests that specify targeting
such a revision fail. We retain the testing of the correct defined OS
version number but switch to compile-only testing for these two tests.

[Darwin, X86, testsuite] Adjust test for Darwin's align syntax.
Darwin has a .align taking a power of 2 by default, so that some
tests expecting a byte count are failing, fixed by adjusting the
scan-asms. We also avoid the ABI-mandated indirection for common
and PIC extras for m32 (by adjusting compile options).

[Darwin, testsuite] Address PR91087 - XFAIL parts of pr16855.C.
The testcase is failing to instrument part of the source because of a bug
in the ordering of static DTORs. It seems unlikely that this is generically
fixable in the toolchain (and given that it's likely to be a dynamic loader
change would not be expected to be applied retrospectively to OS versions
that are out of support). To avoid the testsuite noise, xfail the count lines
that don't match (we can adjust the xfails as/when the upstream bug is fixed).
dejagnu xfails do not seem to work when embedded in a line like:
~Test (void) { .... /* count(1) { xfail ... } */ }
the closing brace seems to confuse the parser. The solution is to exapnd the
text onto three lines.
