[DebugInfo] Add support for fp128, ppc_fp128 and x86_fp80 constant values. #88102

Open CarlosAlbertoEnciso opened 7 months ago

CarlosAlbertoEnciso commented 7 months ago

The existing DIBuilder::createConstantValueExpression API accepts an uint64_t. It creates an expression for a variable that does not have an address, but does have a constant value.

Extend support for fp128, ppc_fp128 and x86_fp80 constants.

Here's at least a simple example of GCC producing a value for an fp128 non-type template parameter: https://godbolt.org/z/MGsGo5bGE
