Andrei Safronov	cb6e5b0980	newlib: fix clang atomics ... Correction of the SYNC_LOCK_* macros in stdatomic	2021-10-21 17:34:48 +01:00
Scott Mabin	d5e4fc8356	remove __clang ifdef around atomic emulation ... * CI errors led me to believe these were needed, but as it turns out the load/store intrinsics are required even when idf is built by gcc when linking to a clang based project. * remove ... postfix inside `SYNC_LOCK_TEST_AND_SET` expansion	2021-10-14 15:01:21 +01:00
Scott Mabin	d93b53b9e5	newlib: provide missing atomic libcalls ... Provide emulated atomic load & store libcalls for u8, u16 & u32 integer types. This is required when building with Clang as llvm does not lower these operations to native load / stores, where as gcc does. Provide `sync_lock_test_and_set` atomic implementations for all supported integer types. Closes https://github.com/espressif/esp-idf/issues/7591.
