Ivan Grokhotkov 891eb3b020 freertos: save/restore PS and EPC1 around window spilling ... Since in b0491307, which has introduced the optimized window spill procedure, _xt_context_save did not work correctly when called from _xt_syscall_exc. This was because unlike _xt_lowint1, _xt_syscall_exc does not save PS and EPC1. The new version of _xt_context_save modified PS (on purpose) and EPC1 (accidentally, due to window overflow exceptions), which resulted in a crash upon 'rfi' from the syscall. This commit adds restoring of PS and EPC1 in _xt_context_save. It also slightly reduces the number of instructions used to prepare PS for window spill. Unit test for setjmp/longjmp (which were broken by this regression) is added. Closes https://github.com/espressif/esp-idf/issues/4541		2019-12-27 11:27:01 +01:00
