Subject: [PATCH] bpo-37415: Fix stdatomic.h header check for ICC compiler
|
|
|
|
Fix stdatomic.h header check for ICC compiler: the ICC implementation
|
|
lacks atomic_uintptr_t type which is needed by Python.
|
|
|
|
Test:
|
|
|
|
* atomic_int and atomic_uintptr_t types
|
|
* atomic_load_explicit() and atomic_store_explicit()
|
|
* memory_order_relaxed and memory_order_seq_cst constants
|
|
|
|
But don't test ATOMIC_VAR_INIT(): it's not used in Python.
