irq-generic.h</span></div><div style="color: rgb(69, 69, 69); font-size: 12px; font-family: 'Helvetica Neue', Helvetica, Arial, sans-serif; background-color: transparent; font-style: normal;"><span style="color: rgb(69, 69, 69); font-family: 'Helvetica Neue', Helvetica, Arial, sans-serif; font-size: 12px;"><br></span></div><div style="color: rgb(69, 69, 69); font-size: 12px; font-family: 'Helvetica Neue', Helvetica, Arial, sans-serif; background-color: transparent; font-style: normal;"><span style="color: rgb(69, 69, 69); font-family: 'Helvetica Neue', Helvetica, Arial, sans-serif; font-size: 12px;">2) From what I saw, the set_vector() is mainly used to install a vector & rtems_interrupt_catch() once in the interrupt initialization function. For ex: I'll be working on m68k bsp now. So from what I saw, most of the files use rtems_interrupt_catch() to install an ISR. Following the trend in sparc, I should
change </span>rtems_interrupt_catch() in all files to set_vector() right ?</div><div style="color: rgb(69, 69, 69); font-size: 12px; font-family: 'Helvetica Neue', Helvetica, Arial, sans-serif; background-color: transparent; font-style: normal;"><br></div><div style="color: rgb(69, 69, 69); font-size: 12px; font-family: 'Helvetica Neue', Helvetica, Arial, sans-serif; background-color: transparent; font-style: normal;">Any other crucial points that I should keep in mind ?</div><div style="color: rgb(69, 69, 69); font-size: 12px; font-family: 'Helvetica Neue', Helvetica, Arial, sans-serif; background-color: transparent; font-style: normal;"><br></div><div style="color: rgb(69, 69, 69); font-size: 12px; font-family: 'Helvetica Neue', Helvetica, Arial, sans-serif; background-color: transparent; font-style: normal;"><span style="font-family: arial, helvetica, clean, sans-serif; background-color: transparent; color: rgb(0, 0, 0); font-size:
