I try to build gcc trunk on sparc/sparc64 linux. The configure was done like this:
../gcc/configure --enable-__cxa_atexit --enable-shared --with-cpu=v7 --enable-languages=c,ada,c++,fortran,java,objc,obj-c++,treelang when I enter the libgomp subdir, I see this: make[2]: Entering directory `/usr/local/src/trunk/objdir/sparc64-unknown-linux-gnu/libgomp' make all-recursive make[3]: Entering directory `/usr/local/src/trunk/objdir/sparc64-unknown-linux-gnu/libgomp' Making all in testsuite make[4]: Entering directory `/usr/local/src/trunk/objdir/sparc64-unknown-linux-gnu/libgomp/testsuite' make[4]: Nothing to be done for `all'. make[4]: Leaving directory `/usr/local/src/trunk/objdir/sparc64-unknown-linux-gnu/libgomp/testsuite' make[4]: Entering directory `/usr/local/src/trunk/objdir/sparc64-unknown-linux-gnu/libgomp' if /bin/sh ./libtool --mode=compile /usr/local/src/trunk/objdir/./gcc/xgcc -B/usr/local/src/trunk/objdir/./gcc/ -B/usr/local/sparc64-unknown-linux-gnu/bin/ -B/usr/local/sparc64-unknown-linux-gnu/lib/ -isystem /usr/local/sparc64-unknown-linux-gnu/include -isystem /usr/local/sparc64-unknown-linux-gnu/sys-include -DHAVE_CONFIG_H -I. -I../../../gcc/libgomp -I. -I../../../gcc/libgomp/config/linux/sparc -I../../../gcc/libgomp/config/linux -I../../../gcc/libgomp/config/posix -I../../../gcc/libgomp -Wall -Werror -ftls-model=initial-exec -mcpu=v9 -Wc,-pthread -O2 -g -O2 -MT alloc.lo -MD -MP -MF ".deps/alloc.Tpo" -c -o alloc.lo ../../../gcc/libgomp/alloc.c; \ then mv -f ".deps/alloc.Tpo" ".deps/alloc.Plo"; else rm -f ".deps/alloc.Tpo"; exit 1; fi mkdir .libs /usr/local/src/trunk/objdir/./gcc/xgcc -B/usr/local/src/trunk/objdir/./gcc/ -B/usr/local/sparc64-unknown-linux-gnu/bin/ -B/usr/local/sparc64-unknown-linux-gnu/lib/ -isystem /usr/local/sparc64-unknown-linux-gnu/include -isystem /usr/local/sparc64-unknown-linux-gnu/sys-include -DHAVE_CONFIG_H -I. -I../../../gcc/libgomp -I. -I../../../gcc/libgomp/config/linux/sparc -I../../../gcc/libgomp/config/linux -I../../../gcc/libgomp/config/posix -I../../../gcc/libgomp -Wall -Werror -ftls-model=initial-exec -pthread -mcpu=v9 -O2 -g -O2 -MT alloc.lo -MD -MP -MF .deps/alloc.Tpo -c ../../../gcc/libgomp/alloc.c -fPIC -DPIC -o .libs/alloc.o Now, from where does the -mcpu=v9 come? And, why is not the toplevel configure option --with-cpu=v7 being honoured in libgomp? Or, why don't I get this right you say? The 32 bit variant of libgomp gets done, but, the 64 bit variant gets this...
