Modified Files: src/sys/arch/mac68k/mac68k: intr.c locore.s via.c Log Message: For GCC8, do not omit frame pointer for intr_dispatch() and via1_intr() (-fomit-frame-pointer is enabled for -O and higher for GCC8). This is required by rtclock_intr() which unwinds stack frame of caller! XXXXXX We need to get rid of this hackest hack for rtclock_intr(). This problem was discussed back in 2014: http://mail-index.netbsd.org/port-mac68k/2014/08/15/msg000595.html http://mail-index.netbsd.org/port-mac68k/2014/08/17/msg000600.html http://mail-index.netbsd.org/port-mac68k/2014/08/17/msg000601.html However, unfortunately, the problem has been left untouched until today. The patch attached in the third message works around the problem. But, it adds hard-coded magic numbers to intr_dispatch() and via1_intr(). For real fix, we should probably reconsider whole interrupt handling. Anyway, now kernel compiled by GCC8 works fine as far as I can see.
