Bootstrap comparison failure! (gcc 4.6.x with -O3)
Hi, i often compile 4.6 snapshot images, and they work without problem. Even my longstanding bug about error in Java compilation with -O2, is solved now. But few days ago I was going to do something curious. I wanted to switch -flto. So I used something like this # uname -a Linux tytus 2.6.32-5-686 #1 SMP Wed Jan 12 04:01:41 UTC 2011 i686 GNU/Linux # gcc -v gcc version 4.4.5 (Debian 4.4.5-8) # export FLAGS="-O3 -march=core2 -Wl,-O1 -mfpmath=sse" export CFLAGS="$FLAGS" export CXXFLAGS="$FLAGS" /scratch/baryluk/gcc/gcc-4.6-20110305/configure \ --enable-shared \ --enable-multiarch \ --enable-linker-build-id \ --enable-checking=yes \ --enable-stage1-checking=all \ --enable-languages=c,c++,objc,go,fortran,ada,java \ --with-fpmath=sse \ --with-build-config=bootstrap-lto \ --enable-lto \ --enable-objc-gc \ --enable-plugin \ --enable-gold \ --with-system-zlib \ --without-included-gettext \ --enable-cloog-backend=isl \ CFLAGS="$CFLAGS" CXXFLAGS="$CXXFLAGS" make BOOT_CFLAGS="$CFLAGS -flto" CFLAGS_FOR_BUILD="$CFLAGS" CXXFLAGS_FOR_BUILD="$CXXFLAGS" bootstrap And then waited I actually waited 5 days... (each file compiled about 45minutes on average, eating 100% of CPU). Normally whole gcc compiles in 25 minutes on this machine. After wait I got this: yluk/gcc/gcc-4.6-20110305/libgomp -Wall -Werror -ftls-model=initial-exec -march=i486 -mtune=i686 -Wc,-pthread -g -O3 -march=core2 -Wl,-O1 -mfpmath=sse -MT time.lo -MD -MP -MF .deps/time.Tpo -c -o time.lo /scratch/baryluk/gcc/ gcc-4.6-20110305/libgomp/config/posix/time.c libtool: compile: /scratch/baryluk/gcc/obiekty/./gcc/xgcc -B/scratch/baryluk/gcc/obiekty/./gcc/ -B/usr/local/i68 6-pc-linux-gnu/bin/ -B/usr/local/i686-pc-linux-gnu/lib/ -isystem /usr/local/i686-pc-linux-gnu/include -isystem /u sr/local/i686-pc-linux-gnu/sys-include -DHAVE_CONFIG_H -I. -I/scratch/baryluk/gcc/gcc-4.6-20110305/libgomp -I/scr atch/baryluk/gcc/gcc-4.6-20110305/libgomp/config/linux/x86 -I/scratch/baryluk/gcc/gcc-4.6-20110305/libgomp/config /linux -I/scratch/baryluk/gcc/gcc-4.6-20110305/libgomp/config/posix -I/scratch/baryluk/gcc/gcc-4.6-20110305/libgo mp -Wall -Werror -ftls-model=initial-exec -march=i486 -pthread -mtune=i686 -g -O3 -march=core2 -Wl,-O1 -mfpmath=s se -MT time.lo -MD -MP -MF .deps/time.Tpo -c /scratch/baryluk/gcc/gcc-4.6-20110305/libgomp/config/posix/time.c - fPIC -DPIC -o .libs/time.o libtool: compile: /scratch/baryluk/gcc/obiekty/./gcc/xgcc -B/scratch/baryluk/gcc/obiekty/./gcc/ -B/usr/local/i68 6-pc-linux-gnu/bin/ -B/usr/local/i686-pc-linux-gnu/lib/ -isystem /usr/local/i686-pc-linux-gnu/include -isystem /u sr/local/i686-pc-linux-gnu/sys-include -DHAVE_CONFIG_H -I. -I/scratch/baryluk/gcc/gcc-4.6-20110305/libgomp -I/scr atch/baryluk/gcc/gcc-4.6-20110305/libgomp/config/linux/x86 -I/scratch/baryluk/gcc/gcc-4.6-20110305/libgomp/config /linux -I/scratch/baryluk/gcc/gcc-4.6-20110305/libgomp/config/posix -I/scratch/baryluk/gcc/gcc-4.6-20110305/libgo mp -Wall -Werror -ftls-model=initial-exec -march=i486 -pthread -mtune=i686 -g -O3 -march=core2 -Wl,-O1 -mfpmath=s se -MT time.lo -MD -MP -MF .deps/time.Tpo -c /scratch/baryluk/gcc/gcc-4.6-20110305/libgomp/config/posix/time.c -o time.o >/dev/null 2>&1 mv -f .deps/time.Tpo .deps/time.Plo /bin/bash ./libtool --tag=CC --mode=compile /scratch/baryluk/gcc/obiekty/./gcc/xgcc -B/scratch/baryluk/gcc/obie kty/./gcc/ -B/usr/local/i686-pc-linux-gnu/bin/ -B/usr/local/i686-pc-linux-gnu/lib/ -isystem /usr/local/i686-pc-li nux-gnu/include -isystem /usr/local/i686-pc-linux-gnu/sys-include -DHAVE_CONFIG_H -I. -I/scratch/baryluk/gcc/g cc-4.6-20110305/libgomp -I/scratch/baryluk/gcc/gcc-4.6-20110305/libgomp/config/linux/x86 -I/scratch/baryluk/gcc/ gcc-4.6-20110305/libgomp/config/linux -I/scratch/baryluk/gcc/gcc-4.6-20110305/libgomp/config/posix -I/scratch/bar yluk/gcc/gcc-4.6-20110305/libgomp -Wall -Werror -ftls-model=initial-exec -march=i486 -mtune=i686 -Wc,-pthread -g -O3 -march=core2 -Wl,-O1 -mfpmath=sse -MT fortran.lo -MD -MP -MF .deps/fortran.Tpo -c -o fortran.lo /scratch/bar yluk/gcc/gcc-4.6-20110305/libgomp/fortran.c libtool: compile: /scratch/baryluk/gcc/obiekty/./gcc/xgcc -B/scratch/baryluk/gcc/obiekty/./gcc/ -B/usr/local/i68 6-pc-linux-gnu/bin/ -B/usr/local/i686-pc-linux-gnu/lib/ -isystem /usr/local/i686-pc-linux-gnu/include -isystem /u sr/local/i686-pc-linux-gnu/sys-include -DHAVE_CONFIG_H -I. -I/scratch/baryluk/gcc/gcc-4.6-20110305/libgomp -I/scr atch/baryluk/gcc/gcc-4.6-20110305/libgomp/config/linux/x86 -I/scratch/baryluk/gcc/gcc-4.6-20110305/libgomp/config /linux -I/scratch/baryluk/gcc/gcc-4.6-20110305/libgomp/config/posix -I/scratch/baryluk/gcc/gcc-4.6-20110305/libgo mp -Wall -Werror -ftls-model=initial-exec -march=i486 -pthread -mtune=i686 -g -O3 -march=core2 -Wl,-O1 -mfpmath=s se -MT fortran.lo -MD -MP -MF .deps/fortran.Tpo -c /scratch/baryluk/gcc

LTO (or rather the first phase of it) needs quite a bit more memory than a normal build. I suspect you don't want to do this with less than 4GB, better 8G. If you have /tmp in shmfs it is also much worse because there will be large temporary files in memory too (workaround is to use TMPDIR=/some/dir/on/disk) > > After wait I got this: You have to use -frandom-seed=1 to avoid LTO bootstrap failures. If you use the build config line above that is done by default. -Andi -- a...@linux.intel.com -- Speaking for myself only
Re: Bootstrap comparison failure! (gcc 4.6.x with -O3)
> Is this because I manually changed BOOT_CFLAGS as passed to make? As previously said, you ought to avoid fiddling with BOOT_CFLAGS in any case. Configure --with-build-config=bootstrap-lto --with-fpmath=sse --with-arch=xxx and so on, and just type "make". > And why it took so long? Probably because you're also fiddling with configure checking options. Avoid doing that if you aren't familiar with them. -- Eric Botcazou

I doubt many people would disagree, but someone needs to do the work (in other words "patches welcome"!) The GCC wiki could be a good place for people to add such information without needing write access to the wwwdocs repository.
Re: GCC 4.6 Successful Build and Install
Hello everyboy, Some for us, we manage to pass the all base of the next major release of NuTyX on gcc 4.6.0. We were actually ready and just waiting for it. If you are intersted in the results. Here are the links of the logs. Pass 1 and 2 are as suggested by Linux From Scratch and release is the real build of NuTyX (pass3) The i686 arch http://kiao.no-ip.info/NuTyX/logs/2011/i686/?C=M;O=D The x86_64 arch http://sibelle.dyndns.org/log/pakxe/x86_64/ Tanks a lot for this amazing work My best regards Thierry > configure.guess: > > x86_64-unknown-linux-gnu > > gcc -v: > > Using built-in specs. > COLLECT_GCC=gcc > COLLECT_LTO_WRAPPER=/ad3/gma/go-gcc-build/libexec/gcc/x86_64-unknown-linux-gnu/4.6.0/lto-wrapper > Target: x86_64-unknown-linux-gnu > Configured with: /ad3/gma/go-build-work/gcc-4.6.0/configure > --prefix=/ad3/gma/go-gcc-build --enable-languages=c,c++,go > Thread model: posix > gcc version 4.6.0 (GCC) > > Languages: > > c,c++,go > > /etc/issue: > > Ubuntu 10.04.2 LTS \n \l > > uname -a: > > Linux tjjackson 2.6.32-30-generic #59-Ubuntu SMP Tue Mar 1 21:30:46 UTC > 2011 x86_64 GNU/Linux > > dpkg -l libc6: > > Desired=Unknown/Install/Remove/Purge/Hold > | > Status=Not/Inst/Cfg-files/Unpacked/Failed-cfg/Half-inst/trig-aWait/Trig-pend > |/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad) > ||/ Name VersionDescription > +++-==-==- > ii libc6 2.11.1-0ubuntu Embedded GNU C Library: Shared libraries > > Misc: > > I had to install package: libc6-dev-i386 to get a successful build. > > Goal: working gccgo > > Results: > > - Simple go programs compile > - Need to use LD_LIBRARY_PATH to get executables to run > > >
