Very strange to see the bootstrap process result in a 64-bit ELF object within stage1 area : $ ../gcc-9.1.0/configure --disable-nls --enable-threads=posix \ --enable-shared --enable-bootstrap \ --enable-stage1-languages=c,c++ --enable-stage1-checking=misc \ --enable-languages=c,c++,objc,obj-c++,fortran,go,lto . . . seems to work just fine. Kick off make and very very quickly ( fast machines these days ) I see : . . . # @multilib_flags@ is still needed because this may use # /opt/bw/build/gcc-9.1.0_rhel_74_3.10.0-693.el7.x86_64.001/./gcc/xgcc -B/opt/bw/build/gcc-9.1.0_rhel_74_3.10.0-693.el7.x86_64.001/./gcc/ -B/opt/bw/gcc9/x86_64-pc-linux-gnu/bin/ -B/opt/bw/gcc9/x86_64-pc-linux-gnu/lib/ -isystem /opt/bw/gcc9/x86_64-pc-linux-gnu/include -isystem /opt/bw/gcc9/x86_64-pc-linux-gnu/sys-include -fno-checking and -O2 -O2 -m64 -g -march=opteron -Wl,-rpath=/opt/bw/lib,--enable-new-dtags -fno-builtin -malign-double -mpc80 -DIN_GCC -W -Wall -Wno-narrowing -Wwrite-strings -Wcast-qual -Wno-format -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -isystem ./include -fpic -mlong-double-80 -DUSE_ELF_SYMVER -g -DIN_LIBGCC2 -fbuilding-libgcc -fno-stack-protector directly. # @multilib_dir@ is not really necessary, but sometimes it has # more uses than just a directory name. /bin/sh ../../../../gcc-9.1.0/libgcc/../mkinstalldirs 32 /opt/bw/build/gcc-9.1.0_rhel_74_3.10.0-693.el7.x86_64.001/./gcc/xgcc -B/opt/bw/build/gcc-9.1.0_rhel_74_3.10.0-693.el7.x86_64.001/./gcc/ -B/opt/bw/gcc9/x86_64-pc-linux-gnu/bin/ -B/opt/bw/gcc9/x86_64-pc-linux-gnu/lib/ -isystem /opt/bw/gcc9/x86_64-pc-linux-gnu/include -isystem /opt/bw/gcc9/x86_64-pc-linux-gnu/sys-include -fno-checking -O2 -O2 -m64 -g -march=opteron -Wl,-rpath=/opt/bw/lib,--enable-new-dtags -fno-builtin -malign-double -mpc80 -DIN_GCC -W -Wall -Wno-narrowing -Wwrite-strings -Wcast-qual -Wno-format -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -isystem ./include -fpic -mlong-double-80 -DUSE_ELF_SYMVER -g -DIN_LIBGCC2 -fbuilding-libgcc -fno-stack-protector -shared -nodefaultlibs -Wl,--soname=libgcc_s.so.1 -Wl,--version-script=libgcc.map -o 32/libgcc_s.so.1.tmp -O2 -m64 -g -march=opteron -Wl,-rpath=/opt/bw/lib,--enable-new-dtags -fno-builtin -malign-double -mpc80 -m32 -B./ _muldi3_s.o _negdi2_s.o _lshrdi3_s.o _ashldi3_s.o _ashrdi3_s.o _cmpdi2_s.o _ucmpdi2_s.o _clear_cache_s.o _trampoline_s.o __main_s.o _absvsi2_s.o _absvdi2_s.o _addvsi3_s.o _addvdi3_s.o _subvsi3_s.o _subvdi3_s.o _mulvsi3_s.o _mulvdi3_s.o _negvsi2_s.o _negvdi2_s.o _ctors_s.o _ffssi2_s.o _ffsdi2_s.o _clz_s.o _clzsi2_s.o _clzdi2_s.o _ctzsi2_s.o _ctzdi2_s.o _popcount_tab_s.o _popcountsi2_s.o _popcountdi2_s.o _paritysi2_s.o _paritydi2_s.o _powisf2_s.o _powidf2_s.o _powixf2_s.o _powitf2_s.o _mulhc3_s.o _mulsc3_s.o _muldc3_s.o _mulxc3_s.o _multc3_s.o _divhc3_s.o _divsc3_s.o _divdc3_s.o _divxc3_s.o _divtc3_s.o _bswapsi2_s.o _bswapdi2_s.o _clrsbsi2_s.o _clrsbdi2_s.o _fixunssfsi_s.o _fixunsdfsi_s.o _fixunsxfsi_s.o _fixsfdi_s.o _fixdfdi_s.o _fixxfdi_s.o _fixunssfdi_s.o _fixunsdfdi_s.o _fixunsxfdi_s.o _floatdisf_s.o _floatdidf_s.o _floatdixf_s.o _floatundisf_s.o _floatundidf_s.o _floatundixf_s.o _divdi3_s.o _moddi3_s.o _divmoddi4_s.o _udivdi3_s.o _umoddi3_s.o _udivmoddi4_s.o _udiv_w_sdiv_s.o cpuinfo_s.o tf-signs_s.o sfp-exceptions_s.o addtf3_s.o divtf3_s.o eqtf2_s.o getf2_s.o letf2_s.o multf3_s.o negtf2_s.o subtf3_s.o unordtf2_s.o fixtfsi_s.o fixunstfsi_s.o floatsitf_s.o floatunsitf_s.o fixtfdi_s.o fixunstfdi_s.o floatditf_s.o floatunditf_s.o extendsftf2_s.o extenddftf2_s.o extendxftf2_s.o trunctfsf2_s.o trunctfdf2_s.o trunctfxf2_s.o enable-execute-stack_s.o unwind-dw2_s.o unwind-dw2-fde-dip_s.o unwind-sjlj_s.o unwind-c_s.o emutls_s.o libgcc.a -lc && rm -f 32/libgcc_s.so && if [ -f 32/libgcc_s.so.1 ];
