I see a number of failures in the gcc.dg-struct-layout-1 testcases when executed after being compiled at -m64. The exact failures are listed at...
http://gcc.gnu.org/ml/gcc/2006-09/msg00211.html I have modified gcc.dg/compat/struct-layout-1_test.h to just contain... T(94,struct atal16{}a;,) and executed make check-gcc RUNTESTFLAGS="--target_board=unix'{-m64}' compat.exp" to obtain the commands for creating the files involved in this test case... sw/src/fink.build/gcc4-4.1.999-20060911/darwin_objdir/gcc/xgcc -B/sw/src/fink.build/gcc4-4.1.999-20060911/darwin_objdir/gcc/ -w -DSKIP_DECIMAL_FLOAT -fno-show-column -c -m64 -save-temps -g -o c_compat_x_tst.o /sw/src/fink.build/gcc4-4.1.999-20060911/gcc-4.2-20060911/gcc/testsuite/gcc.dg/compat/struct-layout-1_x.c /sw/src/fink.build/gcc4-4.1.999-20060911/darwin_objdir/gcc/xgcc -B/sw/src/fink.build/gcc4-4.1.999-20060911/darwin_objdir/gcc/ -DSKIP_DECIMAL_FLOAT -fno-show-column -c -g -m64 -save-temps -o c_compat_main_tst.o /sw/src/fink.build/gcc4-4.1.999-20060911/gcc-4.2-20060911/gcc/testsuite/gcc.dg/compat/struct-layout-1_main.c /sw/src/fink.build/gcc4-4.1.999-20060911/darwin_objdir/gcc/xgcc -B/sw/src/fink.build/gcc4-4.1.999-20060911/darwin_objdir/gcc/ c_compat_main_tst.o c_compat_x_tst.o c_compat_y_tst.o -g -save-temps -fno-show-column -lm -m64 -o gcc-dg-compat-struct-layout-1-01 The resulting preprocessed and assembly files are provided.
