Raphael Isemann d1d6049e9d [lldb][NFC] Remove dead logging code from DWARFASTParserClang::CompleteRecordType
This code is behind a `if (log)` that is always a nullptr as the initializer
was commented out. One could uncomment the initializer code, but then this logging
code just leads to a deadlock as it tries to aquire the module lock.
This removes the logging code until I get this working again.

Pavel Labath 38870af859 [lldb] Remove FileSpec->CompileUnit inheritance
Summary:
CompileUnit is a complicated class. Having it be implicitly convertible
to a FileSpec makes reasoning about it even harder.

This patch replaces the inheritance by a simple member and an accessor
function. This avoid the need for casting in places where one needed to
force a CompileUnit to be treated as a FileSpec, and does not add much
verbosity elsewhere.

It also fixes a bug where we were wrongly comparing CompileUnit& and a
CompileUnit*, which compiled due to a combination of this inheritance
and the FileSpec*->FileSpec implicit constructor.

Victor Campos e478385e77 [ARM] Fix instruction selection for ARMISD::CMOV with f16 type
Summary:
In the cases where the CMOV (f16) SDNode is used with condition codes
LT, LE, VC or NE, it is successfully selected into a VSEL instruction.

In the remaining cases, however, instruction selection fails since VSEL
does not support other condition codes.

This patch handles such cases by using the single-precision version of
the VMOV instruction.

Version revision. This field shall be set to 1.
(https://refspecs.linuxfoundation.org/LSB_5.0.0/LSB-Core-generic/LSB-Core-generic/symversion.html)

Our code should check the struct version for correctness. This patch does that.
(This will help to simplify or eliminate ELFDumper<ELFT>::LoadVersionDefs() which
has it's own logic to parse version definitions for no reason. It checks the

Hideto Ueno 6c742fdbf4 [Attributor] Deduce dereferenceable based on accessed bytes map
Summary:
This patch introduces the deduction based on load/store instructions whose pointer operand is a non-inbounds GEP instruction.
For example if we have,
```
void f(int *u){
 u[0] = 0;
 u[1] = 1;
 u[2] = 2;
}
```
then u must be dereferenceable(12).

This patch is inspired by D64258

Lang Hames 674df13b5f [ORC][JITLink] Add support for weak references, and improve handling of static
libraries.

This patch substantially updates ORCv2's lookup API in order to support weak
references, and to better support static archives. Key changes:

-- Each symbol being looked for is now associated with a SymbolLookupFlags
   value. If the associated value is SymbolLookupFlags::RequiredSymbol then
   the symbol must be defined in one of the JITDylibs being searched (or be
   able to be generated in one of these JITDylibs via an attached definition
   generator) or the lookup will fail with an error. If the associated value is
   SymbolLookupFlags::WeaklyReferencedSymbol then the symbol is permitted to be
   undefined, in which case it will simply not appear in the resulting
   SymbolMap if the rest of the lookup succeeds.

   Since lookup now requires these flags for each symbol, the lookup method now
   takes an instance of a new SymbolLookupSet type rather than a SymbolNameSet.
   SymbolLookupSet is a vector-backed set of (name, flags) pairs. Clients are
   responsible for ensuring that the set property (i.e. unique elements) holds,
   though this is usually simple and SymbolLookupSet provides convenience
   methods to support this.

-- Lookups now have an associated LookupKind value, which is either
   LookupKind::Static or LookupKind::DLSym. Definition generators can inspect
   the lookup kind when determining whether or not to generate new definitions.
   The StaticLibraryDefinitionGenerator is updated to only pull in new objects
   from the archive if the lookup kind is Static. This allows lookup to be
   re-used to emulate dlsym for JIT'd symbols without pulling in new objects
   from archives (which would not happen in a normal dlsym call).

-- JITLink is updated to allow externals to be assigned weak linkage, and
   weak externals now use the SymbolLookupFlags::WeaklyReferencedSymbol value
   for lookups. Unresolved weak references will be assigned the default value of
   zero.

Since this patch was modifying the lookup API anyway, it alo replaces all of the
"MatchNonExported" boolean arguments with a "JITDylibLookupFlags" enum for
readability. If a JITDylib's associated value is
JITDylibLookupFlags::MatchExportedSymbolsOnly then the lookup will only
match against exported (non-hidden) symbols in that JITDylib. If a JITDylib's
associated value is JITDylibLookupFlags::MatchAllSymbols then the lookup will
match against any symbol defined in the JITDylib.

Konrad Kleine c671639af6 [lldb] NFC: refactor CompileUnit::ResolveSymbolContext
Summary:
I found the above named method hard to read because it had

a) many nested blocks,
b) one return statement at the end with some logic involved,
c) a duplicated while-loop with just small differences in it.

I decided to refactor this function by employing an early exit strategy.
In order to capture the logic in the return statement and to not have it
repeated more than once I chose to implement a very small lamda function
that captures all the variables it needs.
I also replaced the two while-loops with just one.

This is a non-functional change (NFC).

Summary:
Pre gfx9 we need to scavenge a 64-bit SGPR to use as the carry out for an Add.
If only one SGPR was available this crashed when trying to scavenge another

Instead, reuse a 32-bit SGPR from the carry out as the offset register.

Also prefer to use vcc for the unused carry out when it is available.

Simon Tatham acd7fe8636 [AArch64][v8.3a] Don't emit LDRA '[xN]!' alias in disassembly.
Summary:
In rG643ac6c0420b, the syntax `ldraa x1, [x0]!` was added as an alias
for `ldraa x1, [x0, #0]!`. That syntax is less obvious in meaning, and
also will not be accepted by assemblers that haven't been updated yet.
So it would be better not to emit it as the preferred disassembly for
that instruction.

This change lowers the EmitPriority of the new alias so that the more
explicit syntax `[x0, #0]!` is preferred by the disassembler. The new
syntax is still accepted by the assembler.
