gcc-4.7.4: libgcc2.h:157: error: unable to emulate 'TF'

gcc-4.7.4: libgcc2.h:157: error: unable to emulate 'TF'

[Jan Nieuwenhuizen]

Hi!

I'm working on a full source bootstrap for a GNU system, GuixSD in
particular.  With the Mes 0.16 release I thought it was done, but now it
seems I'm stuck.

Using the MesCC C99 compiler written in Guile Scheme, I compiled tcc-0.9.26
and a tiny Mes C library, barely enough to build

    binutils-2.20.1, gcc-2.95.3, and glibc-2.2.5

Using those tools, I built

    binutils-2.20.1, gcc-4.1.0, and glibc-2.3.6

My attempts to build gcc-4.7.4 are failing, the most common error that I
get is

     i386-unknown-linux-gcc --sysroot=/gnu/store/jdjpfzjr2zf3xbf7ssl11ljwpq7spid8-glibc-mesboot-2.3.6/include   -g -O2 -O2  -g -O2 -DIN_GCC   -W -Wall -Wwrite-strings -Wcast-qual -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition  -isystem ./include   -fpic -g -DIN_LIBGCC2 -fno-stack-protector   -fpic -I. -I. -I../../host-i386-unknown-linux/gcc -I../.././libgcc -I../.././libgcc/. -I../.././libgcc/../gcc -I../.././libgcc/../include  -DHAVE_CC_TLS  -DUSE_TLS -o _muldi3.o -MT _muldi3.o -MD -MP -MF _muldi3.dep -DL_muldi3 -c ../.././libgcc/libgcc2.c

     ../.././libgcc/libgcc2.h:376: error: expected '=', ',', ';', 'asm' or '__attribute__' before '__moddi3'
     ...

Gcc-4.7.4 advertises it can be built with gcc-2.95 and binutils-2.13.1
and glibc-2.2.5.

Since mes 0.16 was released two weeks ago I have tried many things, but
not knowing where this error comes makes progress difficult, e.g.: I
didn't manage to compile any glibc > 2.3.6, but that may not be
necessary?

Greetings,
janneke

What do you get if you grep for "error: " in the xxx/libgcc/config.log under 
the builddir?
It would also be helpful if you could post also your libiberty/config.h

You have attached config.h of 2 targets.
Is just one of them failing, or both?
And of course: are they both using the same target arch, just differing in 
64bit/32bit?

The difference in them is:
diff /tmp/build-i686-pc-linux-gnu--libiberty--config.h 
/tmp/host-i386-unknown-linux--libiberty--config.h |  less -Sn

< #define HAVE_MMAP 1
---
 > /* #undef HAVE_MMAP */
444c444
< #define STACK_DIRECTION -1
---
 > #define STACK_DIRECTION 0

If they both are the same arch then I would suggest to get the one fixed first 
where the STACK_DIRECTION is seemingly detected wrongly.


And don't use -Werror when compiling, ie. don't treat warnings as error.


And try to find out the reason for the above configure-error:

 > conftest.c:11: error: expected '=', ',', ';', 'asm' or '__attribute__' 
before 'x'
 > conftest.c:11: error: expected '=', ',', ';', 'asm' or '__attribute__'

I forgot to ask: please post also the "error: "'s in libiberty/config.log, ie. 
the grep-output like above.

It seems that the errors you were getting are related to 128 bit floating
point support. It also seems that 128 bit floating point support is enabled
on 64 bits. I'm not sure about the 32 bit case though, do you get the same
error there?

I hoped to just get one, but I get two; I configure using

    ../build/configure --host=i386-unknown-linux --target=i386-unknown-linux ...

> And of course: are they both using the same target arch, just

Not even, this is inside a 32bit VM.  I was hoping to build an x86
toolchain on x86_64, but after these problems I setup a 32bit VM

Maybe I should use

    --host=i686-pc-linux-gnu --target=i686-pc-linux-gnu

?

Hmm, this is definitely wrong.

I'll have a look at this first...

Ah!  That makes me even more supicious... I was wondering about this
command

    i386-unknown-linux-gcc ... -DIN_GCC -o _muldi3.o -c ../.././libgcc/libgcc2.c

this i386-unknown-linux-gcc compiler is the bootstrap compiler,
gcc-4.1.0 (or we may be able to use 2.95.3); is that OK?  Shouldn't the
new `xgcc' compiler be used to compile libgcc2?

TFmode is for 128 bit floats.

https://gcc.gnu.org/ml/gcc-patches/2008-06/msg01747.html
https://gcc.gnu.org/onlinedocs/gcc-4.8.5/gccint/Type-Layout.html

The softfp emulation is in libgcc.

Some great progress!  I found the

    build-i686-pc-linux-gnu
    host-i386-unknown-linux

build directories very suspicous.  I found that in my bootstrap I used
the older `i386-unknown-linux' only because I started with a very early
binutils that didn't know about i686-*linux-gnu yet.

So I have changed the entire bootstrap to use i686-unknown-linux-gnu and
configure gcc-4.7.4 using

    ../build/configure
    --build=i686-unknown-linux-gnu
    --host=i686-unknown-linux-gnu
    --disable-decimal-float
    --disable-libatomic
    --disable-libcilkrts
    --disable-libgomp
    --disable-libitm
    --disable-libmudflap
    --disable-libquadmath
    --disable-libsanitizer
    --disable-libssp
    --disable-libstdcxx-pch
    --disable-libvtv
    --disable-lto
    --disable-lto-plugin
    --disable-multilib
    --disable-plugin
    --disable-shared
    --disable-threads
    --enable-languages=c
    --enable-static
    --prefix=/gnu/store/mkhbgqfpj17p2pfpza95y56dlw2fmfj4-gcc-mesboot-4.7.4
    --with-build-sysroot=/gnu/store/ffj8vq5zvm26jhw26fcmz3bjqdx5vfly-glibc-mesboot-2.2.5/include
    --with-native-system-header-dir=/gnu/store/ffj8vq5zvm26jhw26fcmz3bjqdx5vfly-glibc-mesboot-2.2.5/include

Now, building _muldi3.o from libgcc2.c passes, interestingly indeed the
fresh `xgcc' compiler is used now

    /tmp/guix-build-gcc-mesboot-4.7.4.drv-0/gcc-4.7.4/build/./gcc/xgcc -B/tmp/guix-build-gcc-mesboot-4.7.4.drv-0/gcc-4.7.4/build/./gcc/ -B/gnu/store/mkhbgqfpj17p2pfpza95y56dlw2fmfj4-gcc-mesboot-4.7.4/i686-unknown-linux-gnu/bin/ -B/gnu/store/mkhbgqfpj17p2pfpza95y56dlw2fmfj4-gcc-mesboot-4.7.4/i686-unknown-linux-gnu/lib/ -isystem /gnu/store/mkhbgqfpj17p2pfpza95y56dlw2fmfj4-gcc-mesboot-4.7.4/i686-unknown-linux-gnu/include -isystem /gnu/store/mkhbgqfpj17p2pfpza95y56dlw2fmfj4-gcc-mesboot-4.7.4/i686-unknown-linux-gnu/sys-include --sysroot=/gnu/store/ffj8vq5zvm26jhw26fcmz3bjqdx5vfly-glibc-mesboot-2.2.5/include   -g -O2 -O2  -g -O2 -DIN_GCC   -W -Wall -Wwrite-strings -Wcast-qual -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition  -isystem ./include   -fpic -g -DIN_LIBGCC2 -fno-stack-protector   -fpic -I. -I. -I../.././gcc -I../../../libgcc -I../../../libgcc/. -I../../../libgcc/../gcc -I../../../libgcc/../include  -DHAVE_CC_TLS  -DUSE_TLS -o _muldi3.o -MT _muldi3.o -MD -MP -MF _muldi3.dep -DL_muldi3 -c ../../../libgcc/libgcc2.c

GNU/Linux targets are assumed to have Pthreads (because they should do).

Use --disable-threads or --enable-threads=single to override the default.

Thanks!  I'm very grateful for your help.  I succeeded in building
gcc-4.7.4 from almost no binary seeds[0] for GuixSD!

The weird error in Subject was caused by configure+make (and my usage of
configure flags, environment settings) trying to use CC_FOR_BUILD (the

Here's the configure that I used, which works.

Congrats!  :-)

Can you give us some info on your project? (mes?)
I think you mentioned TCC, scheme, own header files etc.
Did you still had to use also the old gcc 2.95.3 ?
What's the goal, and why especially that target version gcc 4.7.4 ?
As I could figure out, GuixSD is a (new) GNU package manager, right?
Just a little bit curious about your complicated looking project :-)

Mes[0] aims to help create full source bootstrapping for GNU/Linux
distributions such as GuixSD[1] as part of the bootstrappable builds[2]
effort.

It consists of a mutual self-hosting Scheme interpreter written in
~5,000LOC of simple C and a Nyacc-based C compiler written in Scheme.

> As I could figure out, GuixSD is a (new) GNU package manager, right?

Correct.  Guix is the packagage manager, GuixSD (for System Distribution) is
GNU's GNU/Linux distribution built around it.

> I think you mentioned TCC, scheme, own header files etc.

This MesCC compiler comes with three sizes of Mes lib C: libc for
building mes.c, libc+tcc for building TCC.  Then, there is libc+gnu that
is used together with TCC to build binutils-2.20a and gcc-2.95.3.

> Did you still had to use also the old gcc 2.95.3 ?

We are using gcc 2.95.3 as the first GCC compiler mainly because (after
many experiments with versions from 1.40 to 4.1) it proved the most
"bootstrappable" GCC.  GCC 3 introduces a dependency on dirent, e.g.,
that our naive C library does not support.

If we make our libc+gnu richer then we can probably target a newer GCC,
but it's not obvious to me what the bootstrap consequences of that are.

> What's the goal, and why especially that target version gcc 4.7.4 ?

GCC 4.7.4 is currently used as one of the bootstrap binaries of GuixSD.
Also, it's the most recent GCC compiler that can be considered to be
directly bootstrappable.  I don't consider building a c++ bootstrap
compiler ;-)

The goal is to replace the x86 bootstrap of GNU/Linux distributions,
using a bootstrap [mostly] from source instead of what currently
happens: seeding it with a very large blob of bootstrap binaries.

GuixSD seems the best place to develop this in.

> Just a little bit curious about your complicated looking project :-)

Thanks for showing interest!
