[NFC][PowerPC] Update builtins-ppc-altivec.c to be run under `-faltivec-src-compat=mixed`

This patch adds the `-faltivec-src-compat=mixed` option to the
`builtins-ppc-altivec.c` test.

Currently, the default for `-faltivec-src-compat` is `mixed`. The reason we
explicitly specify `mixed` to the RUN lines of this test is because eventually,
the default will set to `xl`.

Having the default as `xl` changes the CHECKs of this test slightly, as it
reorders some of the `vector bool` and `vector pixel` CHECKs (since under the
`xl` option, `vector bool` and `vector pixel` are treated in the same way as
other vector scalars). Explicitly specifying `mixed` ensures that we are testing
pre-existing Clang behaviour.

3 years ago[ORC][ORC-RT] Introduce ORC-runtime based MachO-Platform.
Lang Hames [Wed, 14 Jul 2021 11:09:36 +0000 (21:09 +1000)]
[ORC][ORC-RT] Introduce ORC-runtime based MachO-Platform.

Adds support for MachO static initializers/deinitializers and eh-frame
registration via the ORC runtime.

This commit introduces cooperative support code into the ORC runtime and ORC
LLVM libraries (especially the MachOPlatform class) to support macho runtime
features for JIT'd code. This commit introduces support for static
initializers, static destructors (via cxa_atexit interposition), and eh-frame
registration. Near-future commits will add support for MachO native
thread-local variables, and language runtime registration (e.g. for Objective-C
and Swift).

The llvm-jitlink tool is updated to use the ORC runtime where available, and
regression tests for the new MachOPlatform support are added to compiler-rt.

Notable changes on the ORC runtime side:

1. The new macho_platform.h / macho_platform.cpp files contain the bulk of the
runtime-side support. This includes eh-frame registration; jit versions of
dlopen, dlsym, and dlclose; a cxa_atexit interpose to record static destructors,
and an '__orc_rt_macho_run_program' function that defines running a JIT'd MachO
program in terms of the jit- dlopen/dlsym/dlclose functions.

2. Replaces JITTargetAddress (and casting operations) with ExecutorAddress
(copied from LLVM) to improve type-safety of address management.

3. Adds serialization support for ExecutorAddress and unordered_map types to
the runtime-side Simple Packed Serialization code.

4. Adds orc-runtime regression tests to ensure that static initializers and
cxa-atexit interposes work as expected.

Notable changes on the LLVM side:

1. The MachOPlatform class is updated to:

  1.1. Load the ORC runtime into the ExecutionSession.
  1.2. Set up standard aliases for macho-specific runtime functions. E.g.
       ___cxa_atexit -> ___orc_rt_macho_cxa_atexit.
  1.3. Install the MachOPlatformPlugin to scrape LinkGraphs for information
       needed to support MachO features (e.g. eh-frames, mod-inits), and
       communicate this information to the runtime.
  1.4. Provide entry-points that the runtime can call to request initializers,
       perform symbol lookup, and request deinitialiers (the latter is
       implemented as an empty placeholder as macho object deinits are rarely
       used).
  1.5. Create a MachO header object for each JITDylib (defining the __mh_header
       and __dso_handle symbols).

2. The llvm-jitlink tool (and llvm-jitlink-executor) are updated to use the
runtime when available.

3. A `lookupInitSymbolsAsync` method is added to the Platform base class. This
can be used to issue an async lookup for initializer symbols. The existing
`lookupInitSymbols` method is retained (the GenericIRPlatform code is still
using it), but is deprecated and will be removed soon.

4. JIT-dispatch support code is added to ExecutorProcessControl.

The JIT-dispatch system allows handlers in the JIT process to be associated with
'tag' symbols in the executor, and allows the executor to make remote procedure
calls back to the JIT process (via __orc_rt_jit_dispatch) using those tags.

The primary use case is ORC runtime code that needs to call bakc to handlers in
orc::Platform subclasses. E.g. __orc_rt_macho_jit_dlopen calling back to
MachOPlatform::rt_getInitializers using __orc_rt_macho_get_initializers_tag.
(The system is generic however, and could be used by non-runtime code).

The new ExecutorProcessControl::JITDispatchInfo struct provides the address
(in the executor) of the jit-dispatch function and a jit-dispatch context
object, and implementations of the dispatch function are added to
SelfExecutorProcessControl and OrcRPCExecutorProcessControl.

5. OrcRPCTPCServer is updated to support JIT-dispatch calls over ORC-RPC.

6. Serialization support for StringMap is added to the LLVM-side Simple Packed
Serialization code.

7. A JITLink::allocateBuffer operation is introduced to allocate writable memory
attached to the graph. This is used by the MachO header synthesis code, and will
be generically useful for other clients who want to create new graph content
from scratch.

D106053 exposed that we've not been taking into account that by bitcasting smaller elements together and then performing a ComputeKnownBits on the result we'd be allowing a poison element to influence other neighbouring elements being used in the pack. Instead we now peek through any existing bitcast to ensure that the source type already matches the width source of the pack node we're trying to match.

This has also been a chance to stop matchShuffleWithPACK creating unused nodes on the fly which could affect oneuse tests during shuffle lowering/combining.

The only regression we're seeing is due to being unable to peek through a bitcast as its on the other side of a extract_subvector - which should go away once we finally allow shuffle combining across different vector widths (by making matchShuffleWithPACK using const SelectionDAG& we've gotten closer to this - see PR45974).

DebugInfo: Name class templates with default arguments consistently (both direct naming, and as a template argument for a function template)

It's noteworthy that GCC has the same bug here, which is a bit
surprising. Both Clang and GCC's bug is only for function template
arguments that are themselves templates with default template arguments
(f1<t1<int[, missing_default_here]>>). Probably because function name
matching isn't generally necessary - whereas type matching is necessary
for DWARF consumers to associate declarations and definitions across
translation units, so the bug's been addressed there already - but
continued to exist for function templates since it's fairly benign
there.

I came across this while working on a change that could reconstitute
these pretty printed names based on the rest of the DWARF, reducing the
size of the DWARF by not having to encode all the template parameters in
the name string. That reconstitution code can't tell the difference
between a defaulted argument or not, so couldn't create the current
buggy-ish output.

Making the names more consistent between direct and indirect references,
and between function and class templates seems all to the good.

(I fixed the function template version of this a few years back in
9fdd09a4ccd01feb8e00be22b17e944e46807746 - clearly I should've looked
more closely and generalized the code better so it only had to be fixed
once - well, doing that here now)
