Silences a static analyzer warning.

llvm-svn: 372118

llvm-svn: 372117

The static analyzer is warning about potential null dereferences of dyn_cast<> results, we can use cast<> directly as we know that these cases should all be CastInst, which is why its working atm and anyway cast<> will assert if they aren't.

MVE loads and stores have a 7 bit immediate range, scaled by the length of the type. This needs to be taught to the stack estimation code to ensure that an emergency spill slot is reserved in case we run out of registers when materialising stack indices.

Also the narrowing loads/stores can be created with frame indices even though they do not accept SP as a register. We need in those cases to make sure we have an emergency register to use as the frame base, as SP can never be used.

Converting the *LoopStart pseudo instructions into DLS/WLS results in
LR being defined. These instructions were inserted on the assumption
that LR would already contain the loop counter because a mov is
introduced during ISel as the the consumers in the loop can only use
LR. That assumption proved wrong!

So perform a safety check, finding an appropriate place to insert the
DLS/WLS instructions or revert if this isn't possible.

We do not support them and fail with llvm_unreachable currently.
This is not the only target we do not support and also seems we are missing

so posted it separatelly.

Currently we only allow using a known named constants
for `Machine` field in YAML documents.

This patch allows using any numbers (valid or "unknown")
and adds test cases for current and new functionality.

With this it is possible to write a test cases for really unknown
EM_* targets.

Follow-up to r371983. Referring to "this program" in the description of
the --version option in the documentation isn't exactly correct, because
the docs are not part of the program, and so "this program" doesn't
really refer to anything. This patch brings the other users of this
terminology into line with the new updates to llvm-size and
llvm-strings.

Most of the test changes are trivial instruction reorderings and differing
register allocations, without any obvious performance impact.

Summary:
There were segfaults as we modified and iterated the instruction maps in
the cache at the same time. This was happening because we created new
instructions while we populated the cache. This fix changes the order
in which we perform these actions. First, the caches for the whole
module are created, then we start to create abstract attributes.

I don't have a unit test but the LLVM test suite exposes this problem.

Summary:
Adds Semantic Ranges capabilities to Clangd server.
Also adds tests for running it via clangd server.

This differs from the LSP spec as the spec needs this to be evaluated on multiple 'pos' and the expected output is an list of list of semantic ranges.
This is majorly for multi cursor and assuming this is a rare thing, we don't want to optimize make things complicated just for this.
This should be done in the LSP level by queueing one request per 'pos' in the input.

D67284 introduced ARMErrataFix.cpp which was derived from
AArch64ErrataFix.cpp. There were some useful refactoring changes made to
ARMErrataFix.cpp made as part of the review. This change applies the
relevant changes back to AArch64ErrataFix.cpp.

Main changes are:
- Old style variable names in comments like IS, are now new style isec.
- Simplify init() collection of mappingSymbols to always start with a code
mapping symbol.
- Simplify logic in mergeCmp().
- Fix one 80 column overflow caused by IS -> isec transformation.

The low-overhead branch extension provides a loop-end 'LE' instruction
that performs no decrement nor compare, it just jumps backwards. This
patch modifies the constant islands pass to try to insert LE
instructions in place of a Thumb2 conditional branch, instead of
shrinking it. This only happens if a cmp can be converted to a cbn/z
and used to exit the loop.
