Preston Faiks commented: https://gitlab.rtems.org/rtems/rtos/rtems/-/issues/5214#note_119874 The caller should not expect the FPSR to be "preserved" (identical) to what it was when it made the call, but it should expect that it contain the "cumulative exception bits" of anything that it calls. In this case it calls a routine which blocks but doesn't have any errors. When it returns it should contain the cumulative errors for that thread of execution, NOT all threads of execution. This is why theaddispatch.c contains this code: ```c **_Thread_Save_fp( executing )**; _Context_Switch( &executing->Registers, &heir->Registers ); ** _Thread_Restore_fp( executing );** ``` -- View it on GitLab: https://gitlab.rtems.org/rtems/rtos/rtems/-/issues/5214#note_119874 You're receiving this email because of your account on gitlab.rtems.org.
