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. + 2001-02-04 Ralf Corsepius <corsepiu@faw.uni-ulm.de> * Makefile.am, rtems/score/Makefile.am: |
