------- Comment #13 from oberlaender at fzi dot de 2010-04-22 09:13 ------- Created an attachment (id=20459) --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=20459&action=view) Output from a gdb session on g++-4.4.3
OK, almost right. I created a debug build for gcc-4.4.3: $ g++-4.4.3 -v Using built-in specs. Target: i486-linux-gnu Configured with: ../gcc-4.4.3/configure --prefix=/home/oberlaen/local/stow/gcc-4.4.3/ --with-bugurl=file:///usr/share/doc/gcc-4.4/README.Bugs --enable-languages=c,c++ --enable-shared --disable-multiarch --enable-linker-build-id --with-system-zlib --without-included-gettext --enable-threads=posix --program-suffix=-4.4.3 --enable-nls --enable-clocale=gnu --enable-libstdcxx-debug --enable-objc-gc --enable-targets=all --disable-multilib --disable-werror --with-arch-32=i486 --with-tune=generic --enable-checking=release --build=i486-linux-gnu --host=i486-linux-gnu --target=i486-linux-gnu Thread model: posix gcc version 4.4.3 (GCC) I built with make CFLAGS="-g -O0" CXXFLAGS="-g -O0" STAGE2_CFLAGS="-g -O0" STAGE3_CFLAGS="-g -O0" I then ran g++-4.4.3 -save-temps -o bugtest.out -c -O2 bugtest.ii and extracted the cc1plus command line through strace. The attachment contains the results from a gdb run on cc1plus -fpreprocessed bugtest.ii -quiet -dumpbase bugtest.ii -mtune=generic -march=i486 -auxbase bugtest -O2 -o bugtest.s Hope this tells you something. Please tell me if I can get you any more info. Best regards, Jan -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43818
