Function core::arch::aarch64::__breakpoint [−][src]
pub unsafe fn __breakpoint(val: i32)
This is supported on AArch64 only.
Inserts a breakpoint instruction.
val is a compile-time constant integer in range [0, 255].
The breakpoint instruction inserted is:
BKPTwhen compiling as T32,BRKwhen compiling as A32 or A64.
Safety
If val is out-of-range the behavior is undefined.
Note
ARM’s documentation defines that __breakpoint accepts the
following values for val:
0...65535when compiling as A32 or A64,0...255when compiling as T32.
The current implementation only accepts values in range [0, 255] - if the
value is out-of-range the behavior is undefined.
