Module abi_check

This module ensures that if a function’s ABI requires a particular target feature, that target feature is enabled both on the callee and all callers.

Functions

• check_call_site_abi 🔒
  Checks that a call expression does not try to pass a vector-passed argument which requires a target feature that the caller does not have, as doing so causes UB because of ABI mismatch.
• check_callees_abi 🔒
• check_feature_dependent_abi 🔒
• check_instance_abi 🔒
  Checks that the ABI of a given instance of a function does not contain vector-passed arguments or return values for which the corresponding target feature is not enabled.
• do_check_abi 🔒
• uses_vector_registers 🔒
