pub unsafe fn __breakpoint(const VAL: i32)Available on ARM only.
Expand description
Inserts a breakpoint instruction.
VAL is a compile-time constant integer in range [0, 255].
The breakpoint instruction inserted is BKPT on A32/T32.
Note
ARM’s documentation defines that __breakpoint accepts the
following values for VAL:
0...65535when compiling as A32,0...255when compiling as T32.
The current implementation only accepts values in range [0, 255].
