[analyzer] Add werror flag for analyzer warnings
Summary:
We're using the clang static analyzer together with a number of
custom analyses in our CI system to ensure that certain invariants
are statiesfied for by the code every commit. Unfortunately, there
currently doesn't seem to be a good way to determine whether any
analyzer warnings were emitted, other than parsing clang's output
(or using scan-build, which then in turn parses clang's output).
As a simpler mechanism, simply add a `-analyzer-werror` flag to CC1
that causes the analyzer to emit its warnings as errors instead.
I briefly tried to have this be `Werror=analyzer` and make it go
through that machinery instead, but that seemed more trouble than
it was worth in terms of conflicting with options to the actual build
and special cases that would be required to circumvent the analyzers
usual attempts to quiet non-analyzer warnings. This is simple and it
works well.

[COFF] Fix /export:foo=bar when bar is a weak alias
Summary:
When handling exports from the command line or from .def files, the
linker does a "fuzzy" string lookup to allow finding mangled symbols.
However, when the symbol is re-exported under a new name, the linker has
to transfer the decorations from the exported symbol over to the new
name. This is implemented by taking the mangled symbol that was found in
the object and replacing the original symbol name with the export name.
Before this patch, LLD implemented the fuzzy search by adding an
undefined symbol with the unmangled name, and then during symbol
resolution, checking if similar mangled symbols had been added after the
last round of symbol resolution. If so, LLD makes the original symbol a
weak alias of the mangled symbol. Later, to get the original symbol
name, LLD would look through the weak alias and forward it on to the
import library writer, which copies the symbol decorations. This
approach doesn't work when bar is itself a weak alias, as is the case in
asan. It's especially bad when the aliasee of bar contains the string
"bar", consider "bar_default". In this case, we would end up exporting
the symbol "foo_default" when we should've exported just "foo".
To fix this, don't look through weak aliases to find the mangled name.
Save the mangled name earlier during fuzzy symbol lookup.

Fix lit tests on Windows related to CR+LF
Problem discovered in the breakpoint lit test, but probably exists in others.
lldb-test splits lines on LF. Input files that are CR+LF separated (as is
common on Windows) then resulted in commands being sent to LLDB that ended
in CR, which confused the command interpreter.
This could be fixed at different levels:
1. Treat '\r' like a tab or space in the argument splitter.
2. Fix the line splitters (plural) in lldb-test.
3. Normalize the test files to LF only.
If we did only 3, I'd expect similar problems to recur, so this patch does
1 and 2. I may also do 3 in a separate patch later, but that's tricky

[ORC] Update symbol lookup to use a single callback with a required symbol state
rather than two callbacks.
The asynchronous lookup API (which the synchronous lookup API wraps for
convenience) used to take two callbacks: OnResolved (called once all requested
symbols had an address assigned) and OnReady to be called once all requested
symbols were safe to access). This patch updates the asynchronous lookup API to
take a single 'OnComplete' callback and a required state (SymbolState) to
determine when the callback should be made. This simplifies the common use case
(where the client is interested in a specific state) and will generalize neatly
as new states are introduced to track runtime initialization of symbols.
Clients who were making use of both callbacks in a single query will now need to
issue two queries (one for SymbolState::Resolved and another for
SymbolState::Ready). Synchronous lookup API clients who were explicitly passing
the WaitOnReady argument will now need neeed to pass a SymbolState instead (for
'WaitOnReady == true' use SymbolState::Ready, for 'WaitOnReady == false' use
SymbolState::Resolved). Synchronous lookup API clients who were using default
arugment values should see no change.

Build with _XOPEN_SOURCE defined on AIX
Summary:
It is useful to build with _XOPEN_SOURCE defined on AIX, enabling X/Open
and POSIX compatibility mode, to work around stray macros and other
bugs in the headers provided by the system and build compiler.
This patch adds the config to cmake to build with _XOPEN_SOURCE defined
on AIX with a few exceptions. Google Test internals require access to
platform specific thread info constructs on AIX so in that case we build
with _ALL_SOURCE defined instead. Libclang also uses header which needs
_ALL_SOURCE on AIX so we leave that as is as well.
We also add building on AIX with the large file API and doing CMake
header checks with X/OPEN definitions so the results are consistent with
the environment that will be present in the build.

[CMake] Add special case for processing LLDB_DOTEST_ARGS
Summary:
Allow to run the test suite when building LLDB Standalone with Xcode against a provided LLVM build-tree that used a single-configuration generator like Ninja.
So far both test drivers, lit-based `check-lldb` as well as `lldb-dotest`, were looking for test dependencies (clang/dsymutil/etc.) in a subdirectory with the configuration name (Debug/Release/etc.). It was implicitly assuming that both, LLDB and the provided LLVM used the same generator. In practice, however, the opposite is quite common: build the dependencies with Ninja and LLDB with Xcode for development*. With this patch it becomes the default.
(* In fact, it turned out that the Xcode<->Xcode variant didn't even build out of the box. It's fixed since D62879)
Once this is sound, I'm planning the following steps:
* add stage to the [lldb-cmake-standalone bot](http://green.lab.llvm.org/green/view/LLDB/job/lldb-cmake-standalone/) to build and test it
* update `Building LLDB with Xcode` section in the docs
* bring the same mechanism to swift-lldb
* fade out the manually maintained Xcode project

[ELF][AArch64] Support for BTI and PAC
Branch Target Identification (BTI) and Pointer Authentication (PAC) are
architecture features introduced in v8.5a and 8.3a respectively. The new
instructions have been added in the hint space so that binaries take
advantage of support where it exists yet still run on older hardware. The
impact of each feature is:
BTI: For executable pages that have been guarded, all indirect branches
must have a destination that is a BTI instruction of the appropriate type.
For the static linker, this means that PLT entries must have a "BTI c" as
the first instruction in the sequence. BTI is an all or nothing
property for a link unit, any indirect branch not landing on a valid
destination will cause a Branch Target Exception.
PAC: The dynamic loader encodes with PACIA the address of the destination
that the PLT entry will load from the .plt.got, placing the result in a
subset of the top-bits that are not valid virtual addresses. The PLT entry
may authenticate these top-bits using the AUTIA instruction before
branching to the destination. Use of PAC in PLT sequences is a contract
between the dynamic loader and the static linker, it is independent of
whether the relocatable objects use PAC.
BTI and PAC are independent features that can be combined. So we can have
several combinations of PLT:
- Standard with no BTI or PAC
- BTI PLT with "BTI c" as first instruction.
- PAC PLT with "AUTIA1716" before the indirect branch to X17.
- BTIPAC PLT with "BTI c" as first instruction and "AUTIA1716" before the
first indirect branch to X17.
The use of BTI and PAC in relocatable object files are encoded by feature
bits in the .note.gnu.property section in a similar way to Intel CET. There
is one AArch64 specific program property GNU_PROPERTY_AARCH64_FEATURE_1_AND
and two target feature bits defined:
- GNU_PROPERTY_AARCH64_FEATURE_1_BTI
-- All executable sections are compatible with BTI.
- GNU_PROPERTY_AARCH64_FEATURE_1_PAC
-- All executable sections have return address signing enabled.
Due to the properties of FEATURE_1_AND the static linker can tell when all
input relocatable objects have the BTI and PAC feature bits set. The static
linker uses this to enable the appropriate PLT sequence.
Neither -> standard PLT
GNU_PROPERTY_AARCH64_FEATURE_1_BTI -> BTI PLT
GNU_PROPERTY_AARCH64_FEATURE_1_PAC -> PAC PLT
Both properties -> BTIPAC PLT
In addition to the .note.gnu.properties there are two new command line
options:
--force-bti : Act as if all relocatable inputs had
GNU_PROPERTY_AARCH64_FEATURE_1_BTI and warn for every relocatable object
that does not.
--pac-plt : Act as if all relocatable inputs had
GNU_PROPERTY_AARCH64_FEATURE_1_PAC. As PAC is a contract between the loader
and static linker no warning is given if it is not present in an input.
Two processor specific dynamic tags are used to communicate that a non
standard PLT sequence is being used.
DTI_AARCH64_BTI_PLT and DTI_AARCH64_BTI_PAC.

[ARM] Fix bugs introduced by the fp64/d32 rework.
Change D60691 caused some knock-on failures that weren't caught by the
existing tests. Firstly, selecting a CPU that should have had a
restricted FPU (e.g. `-mcpu=cortex-m4`, which should have 16 d-regs
and no double precision) could give the unrestricted version, because
`ARM::getFPUFeatures` returned a list of features including subtracted
ones (here `-fp64`,`-d32`), but `ARMTargetInfo::initFeatureMap` threw
away all the ones that didn't start with `+`. Secondly, the
preprocessor macros didn't reliably match the actual compilation
settings: for example, `-mfpu=softvfp` could still set `__ARM_FP` as
if hardware FP was available, because the list of features on the cc1
command line would include things like `+vfp4`,`-vfp4d16` and clang
didn't realise that one of those cancelled out the other.
I've fixed both of these issues by rewriting `ARM::getFPUFeatures` so
that it returns a list that enables every FP-related feature
compatible with the selected FPU and disables every feature not
compatible, which is more verbose but means clang doesn't have to
understand the dependency relationships between the backend features.
Meanwhile, `ARMTargetInfo::handleTargetFeatures` is testing for all
the various forms of the FP feature names, so that it won't miss cases
where it should have set `HW_FP` to feed into feature test macros.
That in turn caused an ordering problem when handling `-mcpu=foo+bar`
together with `-mfpu=something_that_turns_off_bar`. To fix that, I've
arranged that the `+bar` suffixes on the end of `-mcpu` and `-march`
cause feature names to be put into a separate vector which is
concatenated after the output of `getFPUFeatures`.
Another side effect of all this is to fix a bug where `clang -target
armv8-eabi` by itself would fail to set `__ARM_FEATURE_FMA`, even
though `armv8` (aka Arm v8-A) implies FP-Armv8 which has FMA. That was
because `HW_FP` was being set to a value including only the `FPARMV8`
bit, but that feature test macro was testing only the `VFP4FPU` bit.
Now `HW_FP` ends up with all the bits set, so it gives the right
answer.
Changes to tests included in this patch:
* `arm-target-features.c`: I had to change basically all the expected
results. (The Cortex-M4 test in there should function as a
regression test for the accidental double-precision bug.)
* `arm-mfpu.c`, `armv8.1m.main.c`: switched to using `CHECK-DAG`
everywhere so that those tests are no longer sensitive to the order
of cc1 feature options on the command line.
* `arm-acle-6.5.c`: been updated to expect the right answer to that
FMA test.
* `Preprocessor/arm-target-features.c`: added a regression test for
the `mfpu=softvfp` issue.

Set an output file name for the override-new-delete.cpp test.
The android_compile.py script requires one.

AMDGPU: Insert skips for blocks with FLAT

Factor out duplicated code building a MemberExpr and marking it

This reinstates r362563, reverted in r362597.
