[PATCH] D94614: [FPEnv][X86] Platform builtins edition: clang should get from the AST the metadata for constrained FP builtins

[Pengfei Wang via Phabricator via cfe-commits]

pengfei added a comment.

Hi Kevin, what's the intention of adding constrained FP metadata for target dependent builtins? I believe the middle-end passes always ignore these builtins. What's more, will it imply user these builtins have different behaviors under different FP model? But it's not true for most platform builtins, since they are just representative of given instructions.
