Tool/software: TI C/C++ Compiler
SLAU646F claims, in section 8.1, that: "The GCC Compiler supports the same intrinsics that the TI CGT for MSP430 does."
I see that these intrinsics are defined in "include/intrinsics.h", but I don't see where they are defined for the GCC variant. Searching file contents, for example, "__enable_interrupt" doesn't seem present at all?
