Ok this seems to be a bug, also if I'm not sure what's throwing it in, as the pic version should be fixed to not create this problem in general situations.
PIC is not the issue, since it can't find a register from GENERAL_REGS. I think the -Os thingy is the problem, since it enables things like reorder-blocks. Probably, the targets that have assembler should filter these out or ebuild. Can reporter try to Replace -Os with -O2 ?

Tried compiling with -O0, same error more or less, just less GENERAL_REGS not found.
-O0 is broken, try with -O2.
(In reply to comment #6) > -O0 is broken, try with -O2. > Tried with -O2 only (not even -pipe), exact same error.
Quick "me, too" here. Happened rather by accident, not when upgrading, but after enabling USE=nsplugin in make.conf and doing an `emerge --newuse world`. Don't know if it matters in terms of context, but the build changes the CFLAGS all by itself: I'm getting lots of "'-mcpu=' is deprecated" warnings that couldn't possibly be meant for me, I never set that anywhere... And indeed, after the configure there's a message that says "You can tune the compiler flags in vlc-config." When called to show its current flags it says: # vlc-config --cflags -Iinclude -D_FILE_OFFSET_BITS=64 -D__USE_UNIX98 -D_LARGEFILE64_SOURCE -D_REENTRANT -D_THREAD_SAFE -D_GNU_SOURCE -DLOCALEDIR="/usr/share/locale" -DDATA_PATH="/usr/share/vlc" -DPLUGIN_PATH="/usr/lib/vlc" -O3 -ffast-math -funroll-loops -mcpu=pentiumpro For completeness, here's my `emerge info`: Portage 2.0.51.22-r2 (default-linux/x86/2005.0, gcc-3.4.4, glibc-2.3.5-r1, 2.6.13-rc6 i686) ================================================================= System uname: 2.6.13-rc6 i686 Pentium III (Coppermine) Gentoo Base System version 1.12.0_pre6 distcc 2.18.3 i686-pc-linux-gnu (protocols 1 and 2) (default port 3632) [enabled] dev-lang/python: 2.2.3-r5, 2.3.5, 2.4.1-r1 sys-apps/sandbox: 1.2.12 sys-devel/autoconf: 2.13, 2.59-r7 sys-devel/automake: 1.4_p6, 1.5, 1.6.3, 1.7.9-r1, 1.8.5-r3, 1.9.6 sys-devel/binutils: 2.16.1 sys-devel/libtool: 1.5.18-r1 virtual/os-headers: 2.6.11-r2 ACCEPT_KEYWORDS="x86 ~x86" AUTOCLEAN="yes" CBUILD="i686-pc-linux-gnu" CFLAGS="-march=pentium3 -O3 -pipe" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/2/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/3.4/env /usr/kde/3.4/share/config /usr/kde/3.4/shutdown /usr/kde/3/share/config /usr/lib/X11/xkb /usr/lib/mozilla/defaults/pref /usr/share/config /var/qmail/control" CONFIG_PROTECT_MASK="/etc/gconf /etc/terminfo /etc/texmf/web2c /etc/env.d" CXXFLAGS="-march=pentium3 -O3 -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="autoconfig distcc distlocks fixpackages sandbox sfperms strict usersandbox" GENTOO_MIRRORS="http://mirrors.sec.informatik.tu-darmstadt.de/gentoo/ http://ftp-stud.fht-esslingen.de/pub/Mirrors/gentoo/ http://gentoo.inode.at/" MAKEOPTS="-j4" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/local/portage" SYNC="rsync://rsync.de.gentoo.org/gentoo-portage" USE="x86 X aalib alsa apm arts avi berkdb bitmap-fonts canna cdr cjk crypt cscope cups curl eds emboss encode esd faad fam fbcon flac foomaticdb foreign-package fortran gd gdbm gif gimpprint gnome gpm gstreamer gtk gtk2 guile i8x0 iconv imagemagick imlib immqt-bc ipv6 java jpeg junit kde kdeenablefinal libg++ libwww mad matroska mikmod mng motif mozilla moznocompose moznoirc moznomail mozsvg mp3 mpeg ncurses network nls nsplugin ogg oggvorbis opengl operanom2 oss pam pcmcia pdflib perl png python qt quicktime readline samba sdl slang smime speex spell ssl svg svga tcpd tetex tidy tiff truetype truetype-fonts type1-fonts unicode userlocales utf8 vorbis wifi win32codecs wmf wxwindows xface xim xine xml xml2 xmms xv xvid xvmc zeroconf video_cards_i810 userland_GNU kernel_linux elibc_glibc" Unset: ASFLAGS, CTARGET, LANG, LC_ALL, LDFLAGS, LINGUAS Needless to say, setting "-O2" manually has no effect whatsoever...

Is this still an issue? I'm having a hard time reproducing this with gcc-3.4.4-r1 and the flags you guys showed here.

This is reproducible with both gcc version 3.4.4 (Gentoo 3.4.4-r1, ssp-3.4.4-1.0, pie-8.7.8) and gcc version 3.4.3-20050110 (Gentoo Linux 3.4.3.20050110-r2, ssp-3.4.3.20050110-0, pie-8.7.7), by the way.
I am getting the same problem. Doing a google search, I found this page: http://itdp.fh-biergarten.de/transcode-devel/2004-09/msg00325.html When I emerged VLC by doing: CFLAGS=-fomit-frame-pointer emerge vlc it compiled cleanly and seems to work for me. The page above has an explanation about the error message, which may apply to VLC (or not, I don't know much about x86 assembly).
If it helps any...

Problem still persists with vlc-0.8.2-r2. i use the "hardened" flag. switching to vanilla specs with "gcc-config i686-pc-linux-gnu-3.4.4-vanilla" solves the problem.
Temporarily adding CFLAGS=-fomit-frame-pointer as suggested in comment #13 works for me with gcc-3.4.3-r1 and vlc-0.8.2-r2.
Same problem here on x86 hardened config. Switching to vanilla gcc did not solved the problem, but adding -fomit-frame-pointer to CFLAGS gives a successful build both with vanilla and hardened gcc.
This should be fixed in the tree now. I added back the logic to only strip -fomit-frame-pointer for gcc-2, which was mysteriously dropped.
