GCC freezing for a Multiply Chain
Hello Everyone, I am creating a benchmark, where I have a following code: x1 = a * b x2 = x1 * a; x3 = x1* x2; x4 = x2 * x3; x5 = x3 * x4; x6 = x5 * x6; . . . . . . x1000 = x999 * x998; When I do this, and compile using -O3/-O2/-O1, the compiler freezes. Am I doing anything wrong? GCC Version: 4.2.1 Platform: x86_64 (in macOS Snow Leopard). I also tested this on a i386 (Red Hat 4.3.2-7) machine with gcc 4.3.2 and I had the same response. Please CC me in the response since I m not a subscribed member of this mailing list. Any help is highly appreciated! Thanks, Balaji V. Iyer.
Help with an Wierd Error
Hello Everyone, I am trying to build an OpenRISC port of GCC. I am not getting much response from the OR32 people, and this error sounds a bit generic from google searches so I thought if someone would know how to solve it. I build binutils, gcc and newlib as they mentioned in the or32 website. But now I am getting this wierd error when I am trying to compile "Hello World" program == or32-elf-gcc -v /tmp/test.c Reading specs from /opt/or32/lib/gcc/or32-elf/4.2.2/specs Target: or32-elf Configured with: ../gcc-4.2.2/configure --target=or32-elf --prefix=/opt/or32 --with-gnu-as --with-gnu-ld --disable-libssp --with-newlib --enable-languages=c --disable-checking Thread model: single gcc version 4.2.2 /opt/or32/libexec/gcc/or32-elf/4.2.2/cc1 -quiet -v test.c -quiet -dumpbase test.c -auxbase test -version -o /var/folders/kX/kXco8IKOGbKCP9ef7v-8KTI/-Tmp-//cch1Gb3x.s ignoring nonexistent directory "/opt/or32/lib/gcc/or32-elf/4.2.2/../../../../or32-elf/sys-include" #include "..." search starts here: #include <...> search starts here: /opt/or32/lib/gcc/or32-elf/4.2.2/include /opt/or32/lib/gcc/or32-elf/4.2.2/../../../../or32-elf/include End of search list.
