|
+ the return value of slp_save_state() is zero, which
|
||||||
|
+ is placed in x0.
|
||||||
|
+ In that case we (slp_switch) also want to return zero
|
||||||
|
+ (also in x0 of course).
|
||||||
|
+ Now, some GCC versions (seen with 4.8) think it's a
|
||||||
|
+ good idea to save/restore x0 around the call to
|
||||||
|
+ slp_restore_state(), instead of simply zeroing it
|
||||||
|
+ at the return below. But slp_restore_state
|
||||||
|
+ writes random values to the stack slot used for this
|
||||||
|
+ save/restore (from when it once was saved above in
|
||||||
|
+ SLP_SAVE_STATE, when it was still uninitialized), so
|
||||||
|
+ "restoring" that precious zero actually makes us
|
||||||
|
+ return random values. There are some ways to make
|
||||||
|
+ GCC not use that zero value in the normal return path
|
||||||
|
+ (e.g. making err volatile, but that costs a little
|
||||||
|
+ stack space), and the simplest is to call a function
|
||||||
|
+ that returns an unknown value (which happens to be zero),
|
||||||
|
+ so the saved/restored value is unused. */
