[PATCH] D145108: [RISCV][llvm-tblgen] Support conditional definitions using !exists clauses

[Jay Foad via Phabricator via llvm-commits]

foad added a comment.

Hi, this patch makes tablegen crash instead of error on cases like this:

  if !cast<A>("").x then
    def x;

(Based on the test case for https://github.com/llvm/llvm-project/issues/49830)

Could you take a look please?
