◆ computeHash()

static llvm::hash_code computeHash ( SymbolOpInterface symbolOp )

static

Computes a hash code to represent symbolOp based on all its attributes except for the symbol name.

Note: We use the operation's name (not the symbol name) as part of the hash computation. This prevents, for example, mistakenly considering a global variable and a spec constant as duplicates because their descriptor set + binding and spec_id, respectively, happen to hash to the same value.
