From mboxrd@z Thu Jan 1 00:00:00 1970 From: Joel Sherrill To: gas2@cygnus.com Subject: binutils 2.9 powerpc-rtems breakage Date: Mon, 13 Apr 1998 14:21:00 -0000 Message-id: X-SW-Source: 1998/msg00109.html I switched binutils 2.9 in my tree for gas-980314 and was unable to complete a one-tree style build of binutils 2.9, egcs 1.0.2, and newlib 1.8.0. The compilation aborted when trying to compile libgcc2.c for _muldi3. I cut the command down to the following: /usr1/rtems/work/tools/build-powerpc-tools/gcc/xgcc \ -B/usr1/rtems/work/tools/build-powerpc-tools/gcc/ -O2 -DCROSS_COMPILE \ -DIN_GCC -O2 -I./include -g1 -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED \ -fexceptions -Dinhibit_libc -mlittle -mrelocatable-lib -mno-eabi \ -mstrict-align -I. -I../../src/gcc -I../../src/gcc/config -DL_muldi3 \ ../../src/gcc/libgcc2.c -c -v which produces the following output: Reading specs from /usr1/rtems/work/tools/build-powerpc-tools/gcc/specs gcc version egcs-2.90.27 980315 (egcs-1.0.2 release) /usr1/rtems/work/tools/build-powerpc-tools/gcc/cpp -lang-c -v -I./include -I. -I../../src/gcc -I../../src/gcc/config -isystem /usr1/rtems/work/tools/build-powerpc-tools/gcc/include -undef -D__GNUC__=2 -D__GNUC_MINOR__=90 -DPPC -Drtems -D__rtems__ -D__PPC__ -D__rtems__ -D__rtems__ -D__PPC -D__rtems -Asystem(rtems) -Acpu(powerpc) -Amachine(powerpc) -D__CHAR_UNSIGNED__ -D__OPTIMIZE__ -g1 -D_RELOCATABLE -D_CALL_SYSV -D_LITTLE_ENDIAN -D__LITTLE_ENDIAN__ -Amachine(littleendian) -D_ARCH_PPC -DCROSS_COMPILE -DIN_GCC -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -Dinhibit_libc -DL_muldi3 ../../src/gcc/libgcc2.c /tmp/cca06464.i GNU CPP version egcs-2.90.27 980315 (egcs-1.0.2 release) (PowerPC Embedded) #include "..." search starts here: #include <...> search starts here: include . ../../src/gcc ../../src/gcc/config /usr1/rtems/work/tools/build-powerpc-tools/gcc/include /home/joel/egcs-1.0.2/powerpc-rtems/lib/gcc-lib/powerpc-rtems/egcs-2.90.27/include /home/joel/egcs-1.0.2/powerpc-rtems/powerpc-rtems/include End of search list. /usr1/rtems/work/tools/build-powerpc-tools/gcc/cc1 /tmp/cca06464.i -quiet -dumpbase libgcc2.c -mlittle -mrelocatable-lib -mno-eabi -mstrict-align -g1 -O2 -O2 -version -fexceptions -o /tmp/cca06464.s GNU C version egcs-2.90.27 980315 (egcs-1.0.2 release) (powerpc-rtems) compiled by GNU C version 2.7.2.3. /usr1/rtems/work/tools/build-powerpc-tools/gcc/as -mppc -V -Qy -mrelocatable-lib -mlittle -o libgcc2.o /tmp/cca06464.s GNU assembler version 2.9 (powerpc-rtems), using BFD version 2.9 Assembler messages: FATAL: Can't create libgcc2.o: Invalid bfd target 1 returned I can produce a .s file using -s and then assemble that file with: ./as -mppc -V -Qy -mrelocatable-lib libgcc2.s which indicates to me that somehow the rtems configuration lost support for the -mlittle option. powerpc-rtems should be identical to powerpc-eabi if that trips anyone's memory.
