In pre-monorepo times the svn staging directory was `.git/svn`. The below error message wasn't mentioning the new name yet.
Example before:
```

Example after:
```

This change reverts most of the previous register name generation.
The real problem is that RegisterTuple does not generate asm names.
Added optional operand to RegisterTuple. This way we can simplify
register name access and dramatically reduce the size of static
tables for the backend.

Summary:
Deduce the "willreturn" attribute for functions.
For now, intrinsics are not willreturn. More annotation will be done in another patch.

If an intrinsic is defined without outputs, but having side effects,
it still can be removed completely from the program. This patch makes
TableGen not set Attribute::ReadNone for intrinsics which
are declared with IntrHasSideEffects.

Rather than an array of std::initializer_list, generate a table of
offsets and a flat array of the operands for getOperandType. This is a
bit more efficient on platforms that don't manage to get the array of
inintializer_lists initialized at link time (I'm looking at you
macOS). It's also quite quite a bit faster to compile.
llvm-svn: 366278
The InstrInfoEmitter outputs an enum called "OperandType" which gives
numerical IDs to each operand type. This patch makes use of this enum
to define a function called "getOperandType", which allows looking up
the type of an operand given its opcode and operand index.

The jcvt intrinsic defined in ACLE [1] is available when ARM_FEATURE_JCVT is defined.
This change introduces the AArch64 intrinsic, wires it up to the instruction and a new clang builtin function.
The __ARM_FEATURE_JCVT macro is now defined when an Armv8.3-A or higher target is used.
I've implemented the target detection logic in Clang so that this feature is enabled for architectures from armv8.3-a onwards (so -march=armv8.4-a also enables this, for example).
make check-all didn't show any new failures.

Summary:
We agreed to rename `except_ref` to `exnref` for consistency with other
reference types in
https://github.com/WebAssembly/exception-handling/issues/79. This also
renames WebAssemblyInstrExceptRef.td to WebAssemblyInstrRef.td in order
to use the file for other reference types in future.

This was failing to import the AMDGPU truncstore patterns. The
truncating stores from 32-bit to 8/16 were then somehow being
incorrectly selected to a 4-byte store.
A separate check is emitted for the LLT size in comparison to the
specific memory VT, which looks strange to me but makes sense based on
the hierarchy of PatFrags used for the default truncstore PatFrags.
llvm-svn: 366129
Currently AMDGPU uses a CodePatPred to check address spaces from the
MachineMemOperand. Introduce a new first class property so that the
existing patterns can be easily modified to uses the new generated
predicate, which will also be handled for GlobalISel.
I would prefer these to match against the pointer type of the
instruction, but that would be difficult to get working with
SelectionDAG compatbility. This is much easier for now and will avoid
a painful tablegen rewrite for all the loads and stores.
I'm also not sure if there's a better way to encode multiple address
spaces in the table, rather than putting the number to expect.

Add "memtag" sanitizer that detects and mitigates stack memory issues
using armv8.5 Memory Tagging Extension.
It is similar in principle to HWASan, which is a software implementation
of the same idea, but there are enough differencies to warrant a new
sanitizer type IMHO. It is also expected to have very different
performance properties.
The new sanitizer does not have a runtime library (it may grow one
later, along with a "debugging" mode). Similar to SafeStack and
StackProtector, the instrumentation pass (in a follow up change) will be
inserted in all cases, but will only affect functions marked with the
new sanitize_memtag attribute.
