From: "khalek at linuxgamers dot net" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug optimization/14110] altivec code misoptimized with any -O Date: Mon, 15 Mar 2004 12:10:00 -0000 [thread overview] Message-ID: <20040315121037.23962.qmail@sources.redhat.com> (raw) In-Reply-To: <20040211141320.14110.lu_zero@gentoo.org> ------- Additional Comments From khalek at linuxgamers dot net 2004-03-15 12:10 ------- I have something similiar when attempting to build mpegvideo_altivec.c from ffmpeg. The following command always gives an ICE: gcc -Wall -maltivec -mabi=altivec -g -O3 -DHAVE_AV_CONFIG_H -I.. -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -D_GNU_SOURCE -c -o ppc/mpegvideo_altivec.o ppc/mpegvideo_altivec.c Only when dropping -O entirely does it compile. Output when adding -v and -save-tempts is as follows: Reading specs from /usr/lib/gcc-lib/powerpc-linux/3.3.3/specs Configured with: ../src/configure -v --enable-languages=c,c++,java,f77,pascal,objc,ada --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --with-gxx-include-dir=/usr/include/c++/3.3 --enable-shared --with-system-zlib --enable-nls --without-included-gettext --enable-__cxa_atexit --enable-clocale=gnu --enable-java-gc=boehm --enable-java-awt=xlib --enable-objc-gc --disable-multilib powerpc-linux Thread model: posix gcc version 3.3.3 (Debian 20040306) /usr/lib/gcc-lib/powerpc-linux/3.3.3/cc1 -E -quiet -v -I.. -D__GNUC__=3 -D__GNUC_MINOR__=3 -D__GNUC_PATCHLEVEL__=3 -D__unix__ -D__gnu_linux__ -D__linux__ -Dunix -D__unix -Dlinux -D__linux -Asystem=unix -Asystem=posix -DHAVE_AV_CONFIG_H -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -D_GNU_SOURCE ppc/mpegvideo_altivec.c -maltivec -mabi=altivec -Wall -O3 mpegvideo_altivec.i ignoring nonexistent directory "/usr/powerpc-linux/include" #include "..." search starts here: #include <...> search starts here: .. /usr/local/include /usr/lib/gcc-lib/powerpc-linux/3.3.3/include /usr/include End of search list. /usr/lib/gcc-lib/powerpc-linux/3.3.3/cc1 -fpreprocessed mpegvideo_altivec.i -quiet -dumpbase mpegvideo_altivec.c -maltivec -mabi=altivec -auxbase-strip ppc/mpegvideo_altivec.o -g -O3 -Wall -version -o mpegvideo_altivec.s GNU C version 3.3.3 (Debian 20040306) (powerpc-linux) compiled by GNU C version 3.3.3 (Debian 20040306).
