Force putting save_data on the stack rather than in SSE register
|
|
|
|
The signal management does not yet properly save SSE state, so that save_data
|
|
would get overwritten by signal handlers, notably leading to `` shell
|
|
replacement getting empty content because then the io_read RPC retry gets an
|
|
MIG_BAD_ARGUMENTS error.
|
|
|
|
XXX: This is only temporary to fix the common shll replacement issue, and is
|
|
waiting for proper SSE state restoration.
