I'm trying to see if I can build the pdp11 target for languages other than just C, and the answer is for the most part yes. But I' running into an ICE I can't figure out. It's way before the back end comes into the picture as far as I can see, and there's nothing particularly strange looking in the input file that suggests anything.
Any suggestions on where to look? The failure is: libtool: compile: /Users/pkoning/Documents/svn/buildpdp+/./gcc/xgcc -shared-libgcc -B/Users/pkoning/Documents/svn/buildpdp+/./gcc -nostdinc++ -L/Users/pkoning/Documents/svn/buildpdp+/pdp11-aout/libstdc++-v3/src -L/Users/pkoning/Documents/svn/buildpdp+/pdp11-aout/libstdc++-v3/src/.libs -L/Users/pkoning/Documents/svn/buildpdp+/pdp11-aout/libstdc++-v3/libsupc++/.libs -B/usr/local/pdp11-aout/pdp11-aout/bin/ -B/usr/local/pdp11-aout/pdp11-aout/lib/ -isystem /usr/local/pdp11-aout/pdp11-aout/include -isystem /usr/local/pdp11-aout/pdp11-aout/sys-include -I/Users/pkoning/Documents/svn/gcc/libstdc++-v3/../libgcc -I/Users/pkoning/Documents/svn/buildpdp+/pdp11-aout/libstdc++-v3/include/pdp11-aout -I/Users/pkoning/Documents/svn/buildpdp+/pdp11-aout/libstdc++-v3/include -I/Users/pkoning/Documents/svn/gcc/libstdc++-v3/libsupc++ -fno-implicit-templates -Wall -Wextra -Wwrite-strings -Wcast-qual -Wabi -fdiagnostics-show-location=once -frandom-seed=new_opa.lo -g -O2 -std=gnu++1z -c ../../../../gcc/libstdc++-v3/libsupc++/new_opa.cc -o new_opa.o cc1plus: warning: -Wabi won't warn about anything [-Wabi] cc1plus: note: -Wabi warns about differences from the most up-to-date ABI, which is also used by default cc1plus: note: use e.g. -Wabi=11 to warn about changes from GCC 7 ../../../../gcc/libstdc++-v3/libsupc++/new_opa.cc:112:1: internal compiler error: in import_export_decl, at cp/decl2.c:2877 } ^ libbacktrace could not find executable to open Please submit a full bug report, with preprocessed source if appropriate.
