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 🔒

Check the ABI at a call site, emitting an error when:

check_callees_abi 🔒

check_feature_dependent_abi 🔒

check_instance_abi 🔒

Checks the ABI of an Instance, emitting an error when:

do_check_simd_vector_abi 🔒

Checks whether a certain function ABI is compatible with the target features currently enabled for a certain function. is_call indicates whether this is a call-site check or a definition-site check; this is only relevant for the wording in the emitted error.

do_check_unsized_params 🔒

Emit an error when a non-rustic ABI has unsized parameters. Unsized types do not have a stable layout, so should not be used with stable ABIs. is_call indicates whether this is a call-site check or a definition-site check; this is only relevant for the wording in the emitted error.

uses_vector_registers 🔒
