RM57L843: _restore_interupts() intrinsec function is undefined error

Marcio Borges said:

The compiler (TI v20.2.5.7.LTS C++14) says that "_restore_interupts" is undefined. It does not complain about the others (_disable_interrupts, _disable_IRQ , etc).

Found Can't use intrinsics "_restore_interupts();" which says there was a typo in the documentation for the C2000 compiler 6.1.12 (the thread is 14 years old), and the actual function name is _restore_interrupts rather than _restore_interupts (missing 'r').

Perhaps spnu151w for the ARM compiler has the same typo.

Can you try using _restore_interrupts instead.

Looking in a ARM TI v20.2.5.7.LTS installation, the include/_atomic.h file has the following:

__attribute__((target("arm"))) __ATTRIBUTE_NOINLINE__
static void __restore_interrupts(uint32_t t) { _restore_interrupts(t); }

Thanks Chester for providing support on this thread.
