Reproducible: Always Steps to Reproduce: 1. Add "-Os" to CFLAGS in make.conf 2. emerge lyx 3. wait Actual Results: GCC complains of an internal error. Expected Results: LyX is now merged and functional. emerge --info: Portage 2.0.51-r3 (default-linux/x86/2004.3, gcc-3.3.4, glibc-2.3.4.20040808-r1, 2.6.9-rc1-mm5 i686) ================================================================= System uname: 2.6.9-rc1-mm5 i686 AMD Duron(tm) Processor Gentoo Base System version 1.4.16 distcc 2.16 i686-pc-linux-gnu (protocols 1 and 2) (default port 3632) [disabled] ccache version 2.3 [enabled] Autoconf: sys-devel/autoconf-2.59-r5 Automake: sys-devel/automake-1.8.5-r1 Binutils: sys-devel/binutils-2.15.90.0.1.1-r3 Headers: sys-kernel/linux-headers-2.4.19-r1,sys-kernel/linux-headers-2.4.21-r1 Libtools: sys-devel/libtool-1.5.2-r7 ACCEPT_KEYWORDS="x86" AUTOCLEAN="yes" CFLAGS="-march=athlon-tbird -Os -pipe -fstack-protector -fforce-addr" CHOST="i686-pc-linux-gnu" COMPILER="" CONFIG_PROTECT="/etc /usr/X11R6/lib/X11/xkb /usr/kde/2/share/config /usr/kde/3.1/share/config /usr/kde/3.2/share/config /usr/kde/3.3/env /usr/kde/3.3/share/config /usr/kde/3.3/shutdown /usr/kde/3/share/config /usr/lib/mozilla/defaults/pref /usr/share/config /usr/share/texmf/dvipdfm/config/ /usr/share/texmf/dvips/config/ /usr/share/texmf/tex/generic/config/ /usr/share/texmf/tex/platex/config/ /usr/share/texmf/xdvi/ /var/qmail/alias /var/qmail/control" CONFIG_PROTECT_MASK="/etc/gconf /etc/terminfo /etc/env.d" CXXFLAGS="-march=athlon-tbird -Os -pipe -fstack-protector -fforce-addr" DISTDIR="/var/cache/portage/distfiles" FEATURES="autoaddcvs autoconfig ccache distlocks sandbox sfperms strict userpriv usersandbox" GENTOO_MIRRORS="http://gentoo.seren.com/gentoo http://www.ibiblio.org/gentoo ftp://ftp.gtlib.cc.gatech.edu/pub/gentoo http://gentoo.mirrors.pair.com/" MAKEOPTS="-j2" PKGDIR="/var/cache/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/var/cache/portage" PORTDIR_OVERLAY="/var/cache/bmg-main /home/jrogers/ebuilds /usr/local/overlays/deltup" SYNC="rsync://rsync.us.gentoo.org/gentoo-portage" USE="3dnow X aalib acpi alsa apache2 apm auctex avi berkdb bitmap-fonts bonobo caps cdr chroot clisp cmucl crypt cups dga dillo directfb dnd dvd encode esd f77 fam fbcon flac foomaticdb fortran gatos gdbm geoip ggi gif gimpprint gnome gstreamer gtk gtk2 gtkhtml guile imagemagick imap imlib ipv6 jack java javascript jikes jpeg junit ladcca lcms libg++ libwww mad maildir matroska mbox mdb mikmod mitshm mmx mng mozilla moznoirc mozp3p mozsvg mozxmlterm mpeg music mysql ncurses odbc ofx oggvorbis openal opengl oss pam parse-clocks pcre pdflib plotutils png postgres ppds python qt qtmt quicktime radeon readline samba sdl slang snmp spell sqlite ssl stencil-buffer stroke tcltk tcpd tetex theora tiff transcode truetype v4l v4l2 wmf wxwindows x86 xface xfs xine xml xml2 xmms xv xvid zlib video_cards_radeon" jonner@teegra.net 2004-12-10 00:41:57 0000 Created an attachment (id=45665) causes LyX to be built with "-O2" instead of "-Os" This patch allows a successful build on my system. svyatogor@gentoo.org 2004-12-10 02:20:44 0000 Works fine for me with these flags: CFLAGS="-Os -mcpu=i686 -fomit-frame-pointer" CXXFLAGS="-Os -mcpu=i686 -fomit-frame-pointer" Probably it's athlon specific issue? jonner@teegra.net 2004-12-10 19:58:35 0000 Since I seem to have found a bug in GCC, it's not at all surprising that it only triggers with certain CPU models. hsggebhardt@ucdavis.edu 2004-12-11 16:55:34 0000 I see the same result on a pentium4. It didn't work with the following CFLAGS: CFLAGS="-Os -march=pentium4 -mmmx -msse -msse2 -mfpmath=sse -ffast-math -fomit-frame-pointer -pipe" CFLAGS="-Os -march=pentium4" CFLAGS="-Os" It did, however, work with CFLAGS="-O2 -march=pentium4 -mmmx -msse -msse2 -mfpmath=sse -ffast-math -fomit-frame-pointer -pipe". So, it really seems to be related to some flag inside -Os. usata@gentoo.org 2005-02-08 03:25:14 0000 Okay. Thanks for the bug report. I filtered "-Os" from lyx-1.3.5.ebuild. Hope some of you get benefits from this change. 45665 2004-12-10 00:41 0000 causes LyX to be built with "-O2" instead of "-Os" lyx-1.3.5_no-Os.diff text/plain LS0tIC92YXIvY2FjaGUvcG9ydGFnZS9hcHAtb2ZmaWNlL2x5eC9seXgtMS4zLjUuZWJ1aWxkCTIw MDQtMTItMDIgMjM6MTg6MDcuMDAwMDAwMDAwIC0wNTAwCisrKyBlYnVpbGRzL2FwcC1vZmZpY2Uv bHl4L2x5eC0xLjMuNS1yMS5lYnVpbGQJMjAwNC0xMi0wOSAyMzo1MDoxNC4wMDAwMDAwMDAgLTA1 MDAKQEAgLTIsNyArMiw3IEBACiAjIERpc3RyaWJ1dGVkIHVuZGVyIHRoZSB0ZXJtcyBvZiB0aGUg R05VIEdlbmVyYWwgUHVibGljIExpY2Vuc2UgdjIKICMgJEhlYWRlcjogL3Zhci9jdnNyb290L2dl bnRvby14ODYvYXBwLW9mZmljZS9seXgvbHl4LTEuMy41LmVidWlsZCx2IDEuNyAyMDA0LzEyLzAz IDAzOjQwOjI3IHVzYXRhIEV4cCAkCiAKLWluaGVyaXQga2RlLWZ1bmN0aW9ucyBldXRpbHMgbGli dG9vbAoraW5oZXJpdCBrZGUtZnVuY3Rpb25zIGV1dGlscyBsaWJ0b29sIGZsYWctby1tYXRpYwog CiBERVNDUklQVElPTj0iV1lTSVdZTSBmcm9udGVuZCBmb3IgTGFUZVgiCiBIT01FUEFHRT0iaHR0 cDovL3d3dy5seXgub3JnLyIKQEAgLTYzLDYgKzYzLDggQEAKIAogCWV4cG9ydCBXQU5UX0FVVE9D T05GPTIuNQogCisJZmlsdGVyLWZsYWdzIC1mc3RhY2stcHJvdGVjdG9yCisJcmVwbGFjZS1mbGFn cyAtT3MgLU8yCiAJbG9jYWwgZmxhZ3M9IiR7Q1hYRkxBR1N9IC1mbm8tc3RhY2stcHJvdGVjdG9y IgogCXVuc2V0IENGTEFHUwogCXVuc2V0IENYWEZMQUdTCg==
