Mike Rice	2acf77f987	[clang] Update argument checking tablegen code to use a 'full' name (#99993) ... In 92fc1eb0c1ae3813f2ac9208e2c74207aae9d23 the HLSLLoopHint attribute was added with an 'unroll' spelling. There is an existing LoopHint attribute with the same spelling. These attributes have different arguments. The tablegen used to produce checks on arguments uses only the attribute name, making it impossible to return correct info for attribute with different argument types but the same name. Improve the situation by using a 'full' name that combines the syntax, scope, and name. This allows, for example, #pragma unroll and [[unroll(x)]] to coexist correctly even with different argument types. Also fix a bug in the StrictEnumParameters tablegen. If will now correctly specify each parameter instead of only the first.	2024-07-30 10:07:16 -07:00
