(In reply to Kazumoto Kojima from comment #213)
Sorry I missed the use of -jN in your build. Perhaps the failed go compilation
command would be
/srv/glaubitz/gcc/build/./gcc/gccgo -B/srv/glaubitz/gcc/build/./gcc/
-B/usr/local/sh4-unknown-linux-gnu/bin/ -B/usr/local/sh4-unknown-linux-gnu/lib/
-isystem /usr/local/sh4-unknown-linux-gnu/include -isystem
/usr/local/sh4-unknown-linux-gnu/sys-include -O2 -g -I . -c
-fgo-pkgpath=unicode/utf16 ../../../libgo/go/unicode/utf16/utf16.go -o
unicode/utf16.o
Fortunately, I can reproduce the ICE with the cross go compiler. I'll look
into what is going on.
