Summary: We should only have llvm-c-test use libLLVM if the library is built with the default set of components or if LLVM_DYLIB_COMPONENTS includes all the LLVM_LINK_COMPONENTS required for llvm-c-test. Making libLLVM always used causes build failures if libLLVM doesn't include all

If the PC is in the list:

Near as I can tell prefixes are ignored on these instructions except for a comment in the Intel docs about 0xf3. Binutils disassembler seems to ignore prefixes on these instructions. Our disassembler still doesn't distinguish PS and "no prefix" well enough for this to make a functional change, but it helps with experiments I'm doing on a potential new disassembler table builder.

of the abi we should be using. For targets that don't use the
option there's no change, otherwise this allows external users
to set the ABI via string and avoid some of the -backend-option
pain in clang.
Use this option to move the ABI for the ARM port from the
Subtarget to the TargetMachine and update the testcases
accordingly since it's no longer valid to set via -mattr.

same. This will change the "bare metal" ABI from APCS to AAPCS.
The only difference between the front and back end code is that
the code for Triple::GNU was added for environment. That will migrate
to the front end shortly.
Tests updated with the ABI they were originally testing in the case
of bare metal (e.g. -mtriple armv7) or with a -gnu for arm-linux
triples.

This reverts commit r224416, reapplying r224389. The buildbots hadn't
recovered after my revert, waiting until David reverted a couple of his
commits. It looks like it was just bad timing (where we were both
modifying code related to the same assertion). Trying again...
Here's the original text:
When a function gets replaced by `ModuleLinker`, drop superseded
subprograms. This ensures that the "first" subprogram pointing at a
function is the same one that `!dbg` references point at.
This is a stop-gap fix for PR21910. Notably, this fixes Release+Asserts
bootstraps that are currently asserting out in
`LexicalScopes::initialize()` due to the explicit instantiations in
`lib/IR/Dominators.cpp` eventually getting replaced by -argpromotion.
llvm-svn: 224487
Make `DICompositeType` mutators private to prevent misuse. All calls to
`setArrays()` and `setContainingType()` should go through
`DIBuilder::replaceArrays()` and `DIBuilder::replaceVTableHolder()`.
This is a follow-up to r224482 (now that clang has been updated in
r224483).
llvm-svn: 224486
Also corrected the name of the load command to not end in an ’S’ as well as corrected
the name of the MachO::linker_option_command struct and other places that had the
word option as plural which did not match the Mac OS X headers.
llvm-svn: 224485
Add API to DIBuilder to handle self-referencing `DICompositeType`s.
Self-references aren't expected in the debug info graph, and we take
advantage of that by only calling `resolveCycles()` on nodes that were
once forward declarations (otherwise, DIBuilder needs an expensive
tracking reference to every unresolved node it creates, which in cyclic
graphs is *all of them*).
However, clang seems to create self-referencing `DICompositeType`s. Add
API to manage this safely. The paired commit to clang will include the
regression test.
I'll make the `DICompositeType` API `private` in a follow-up to prevent
misuse (I've separated that to prevent build failures from missing the
clang commit).

Start lazy-loading `LTOModule`s that own their contexts. These can only
really be used for parsing symbols, so its unnecessary to ever
materialize their functions.
I looked into using `IRObjectFile::create()` and optionally calling
`materializAllPermanently()` afterwards, but this turned out to be
awkward.
- The default target triple and data layout logic needs to happen
*before* the call to `IRObjectFile::IRObjectFile()`, but after
`Module` was created.
- I tried passing a lambda in to do the module initialization, but
this seemed to require threading the error message from
`TargetRegistry::lookupTarget()` through `std::error_code`.
- I also looked at setting `errMsg` directly from within the lambda,
but this didn't look any better.
(I guess there's a reason we weren't already using that function.)

This fixes a problem where stripCopies() would switch to values in the
main liverange when it crossed a copy instruction. However when joining

This was missed last time around, for the P8 Instruction Scheduling

The ExecutionDepsFix previously mapped each register to 1 or zero
registers of the register class it was called with and therefore
simulating liveness for. This was problematic for cases involving wider
registers like Q0 on ARM where ExecutionDepsFix gets invoked for the Dxx
registers. In these cases the wide register would get mapped to the last
matching D register, while it should have been all matching D registers.
This commit changes the AliasMap to use a SmallVector to map registers
to potentially multiple destination regclass registers. This is required
to avoid regressions with subregister liveness tracking enabled.

This handles the case of a BUILD_VECTOR being constructed out of elements extracted from a vector twice the size of the result vector. Previously this was always scalarized. Now, we try to construct a shuffle node that feeds on extract_subvectors.

Summary:
When generating MIPS assembly, LLVM always overrides the default assembler options by emitting the '.set noreorder', '.set nomacro' and '.set noat' directives,
while GCC uses the default options if an assembly-level function contains inline assembly code.
This becomes a problem when the code generated by LLVM is interleaved with inline assembly which assumes GCC-like assembler options (from Linux, for example).
This patch fixes these conflicts by setting the appropriate assembler options at the beginning of an inline asm block and popping them at the end.
