// doesn't currently account for this in nosplit stack depth checking.

- Functions that may run without a valid G. For example, functions
  that run in early runtime start-up, or that may be entered from C
  code such as cgo callbacks or the signal handler.

Splittable functions ensure there's some amount of space on the stack
for nosplit functions to run in and the linker checks that any static
chain of nosplit function calls cannot exceed this bound.
