--- Comment #54 from Mikael Pettersson <mikpe at it dot uu.se> 2013-03-20 11:05:58 UTC --- Status update: Although gnat is solid enough to rebuild itself with (patched) gcc-4.6 on m68k, there is a regression with (similarly patched) 4.7 that breaks bootstrap: /mnt/scratch/objdir47/./gcc/xgcc -B/mnt/scratch/objdir47/./gcc/ -B/usr/m68k-brewer-linux/bin/ -B/usr/m68k-brewer-linux/lib/ -isystem /usr/m68k-brewer-linux/include -isystem /usr/m68k-brewer-linux/sys-include -c -g -O2 -mcpu=68060 -fpic -W -Wall -gnatpg -nostdinc -mcpu=68060 a-calfor.adb -o a-calfor.o xgcc: internal compiler error: Segmentation fault (program gnat1) Please submit a full bug report, with preprocessed source if appropriate. make[9]: *** [a-calfor.o] Error 4 make[9]: Leaving directory `/mnt/scratch/objdir47/gcc/ada/rts_m68060' make[8]: *** [gnatlib] Error 2 make[8]: Leaving directory `/mnt/scratch/objdir47/gcc/ada' make[7]: *** [gnatlib-shared-default] Error 2 make[7]: Leaving directory `/mnt/scratch/objdir47/gcc/ada' make[6]: *** [gnatlib-shared-dual] Error 2 make[6]: Leaving directory `/mnt/scratch/objdir47/gcc/ada' make[5]: *** [gnatlib-shared] Error 2 make[5]: Leaving directory `/mnt/scratch/objdir47/gcc/ada' make[4]: *** [gnatlib-shared] Error 2 make[4]: Leaving directory `/mnt/scratch/objdir47/m68k-brewer-linux/m68060/libada' make[3]: *** [multi-do] Error 1 make[3]: Leaving directory `/mnt/scratch/objdir47/m68k-brewer-linux/libada' make[2]: *** [all] Error 2 make[2]: Leaving directory `/mnt/scratch/objdir47/m68k-brewer-linux/libada' make[1]: *** [all-target-libada] Error 2 make[1]: Leaving directory `/mnt/scratch/objdir47' make: *** [bootstrap] Error 2 This only occurs when compiling the 68060 variant of the libraries. With multilibs disabled 4.7.3 bootstraps fine w/ Ada. This ICE started with r180192, an ICE fix (PR50780). I don't see anything in that patch that seems m68k or cc0 related, so I suspect it just exposed some latent issue.
