Fixes #157674
On ARM, the presence of a specific bf16 type in the AST is gated by:
```
bool ARMTargetInfo::hasBFloat16Type() const {
// The __bf16 type is generally available so long as we have any fp registers.
return HasBFloat16 || (FPU && !SoftFloat);
}
```
And the target we use when evaluating symbols (derived from the program
file, I think, haven't found it yet) does not enable any of this.
This means that we fall back to __fp16.
So for parts of the testing we just need to expect __fp16 instead, and
others we need to skip because now a class looks like it inherits from
itself.
There's a proper fix here somewhere but I don't know what it is yet.

(#157674)
During debugging applization with __bf16 and _Float16 float types it was
discovered that lldb creates the same CompilerType for them. This can
cause an infinite recursion error, if one tries to create two struct
specializations with these types and then inherit one specialization
from another.

constants (#127206)
This patch adds support for template arguments of
`clang::TemplateArgument::ArgKind::StructuralValue` kind (added in
https://github.com/llvm/llvm-project/pull/78041). These are used for
non-type template parameters such as floating point constants. When LLDB
created `clang::NonTypeTemplateParmDecl`s, it previously assumed
integral values, this patch accounts for structural values too.
Anywhere LLDB assumed a `DW_TAG_template_value_parameter` was
`Integral`, it will now also check for `StructuralValue`, and will
unpack the `TemplateArgument` value and type accordingly.
We can rely on the fact that any `TemplateArgument` of `StructuralValue`
kind that the `DWARFASTParserClang` creates will have a valid value,
because it gets those from `DW_AT_const_value`.

This test needs to be compiled with compilers that support floating point NTTP.
|
|
LLVM started emitting the `DW_AT_const_value` for floating point template parameters since https://github.com/llvm/llvm-project/pull/127045. Adjust the expected type in this test. It's still not quite correct but that requires a separate fix in LLDB.
|
|
This patch adds a new API to `SBType` to retrieve the value of a
template parameter given an index. We re-use the
`TypeSystemClang::GetIntegralTemplateArgument` for this and thus
currently only supports integral non-type template parameters. Types
like float/double are not supported yet.

This is an ongoing series of commits that are reformatting our Python
code. Reformatting is done with `black` (23.1.0).
If you end up having problems merging this commit because you have made
changes to a python file, the best way to handle that is to run `git
checkout --ours <yourfile>` and then reformat it with black.

Eliminate boilerplate of having each test manually assign to `mydir` by calling
`compute_mydir` in lldbtest.py.
