/* The legacy _mcount implementation assumes r11 points to a
4-word APCS frame. This is generally not true for EABI targets,
particularly not in Thumb mode. We assume the mcount
implementation does not require a counter variable (No Counter).
Note that __gnu_mcount_nc will be entered with a misaligned stack.
This is OK because it uses a special calling convention anyway. */
