| | | | | | | | PR 1385/cpukit * cpu_asm.S: When the type rtems_boolean was switched to the C99 bool, the size changed from 4 bytes to 1 byte. The interrupt dispatching code accesses two boolean variables for scheduling purposes and the assembly implementations of this code did not get updated.

| | | | | | | | * cpu_asm.S: Add Coldfire FPU support. * rtems/score/m68k.h: Change the Coldfire CPU defines to be based on the instruction set. Add Tiny RTEMS support to the small memory model RTEMS processors. * rtems/score/cpu.h: Handle the new Tiny RTEMS support.

| | | | | * cpu_asm.S: Reduce mask from 0xffc to 0x3fc so only the vector bits are used when calculating the exception vector.

| | | | | * cpu_asm.S: More PR267 tinkering which eliminates some conditional compilation.

| | | | | | | | | | * cpu_asm.S: Per PR267, the _ISR_Handler() function never was modifying _ISR_Nest_level, and _Watchdog_Insert() requires this variable to be modified to determine if an interrupt may have modified the watchdog chain. Prior to modifying _ISR_Handler(), I had a test that would fail if _ISR_Flash was not commented out in _Watchdog_Insert(). After this modification was made, my test ran flawlessly.

| | | | | | | | | | | | * cpu_asm.S: This patch was co-developed with Eric Norum <eric.norum@usask.ca>. It closes a one instruction window on some m68k CPU cores. It fixes symptoms seen as: 1) No more `interrupt handler invoked twice for a single interrupt'. 2) No more `lockup when mc68360 CPM and PIT interrupts are at different levels'. It does insert a little more overhead on machines without hardware interrupt stacks but correctness has a price.
