--- Comment #2 from Tyler Hardin <th020394 at gmail dot com> 2012-03-21 00:44:39 UTC --- While I admit my knowledge of interrupts on ARM, AVR, CR16, Epiphany, M32C, M32R/D, m68k, MeP, MIPS, RL78, RX and Xstormy16 is limited; I don't see why, if GCC supports interrupts on all of them, then it shouldn't have support for others. Is there something special about them?
