I looked for a "Component" for 'libgcc' but there is no such category so I
chose 'inline-asm' as this is an "extra underscore issue" with '.s' files.

Works. Even though I used "-lgcc" there was no 'collision' between the 
various "conversion functions". The unwanted underscores hide them.

I used the soft-fp "C" source files instead of relying on the double
underscored versions of these functions that are in libgcc and was
able to hand-compile and run ./fp-int-convert-float128.exe .

The Testsuite tests for these "conversion functions" could work
if they were fixed. These files might have first been discussed here:
http://gcc.gnu.org/ml/gcc-patches/2006-05/msg00968.html .

You can use following (slightly wrapped...) patch to enable 128bit soft-fp on
Solaris:

Probably, it works out-of-the-box, otherwise please look into configuration

Thanks, I'll try that this week (working on a P1).

Please read the ChangeLog:

../gcc_trunk/ChangeLog: * configure.ac: Recognize GNU/kOpenSolaris
(*-*-kopensolaris*-gnu).

../gcc_trunk/ChangeLog: * libtool.m4: Add kfreebsd*-gnu and knetbsd*-gnu.



You might want to change that to allow for the new Targets k*bsd and
kopensolaris ("OpenSolaris Kernel with *BSD" and "OpenSolaris Kernel with 
GNU Libc"):

Sorry, you need to change libgcc/config.host in the same way. Look at the end
of the file.

32bit i386 doesn't support TImode.

TImode soft-fp is disabled in libgcc/config/i386/32/t-fprules-softfp. A change
in libgcc/conifg.host is needed to correctly filter these functions out on your
target.

OK.


The file "libgcc/config.host" says this (so I will use it's code):
# This file bears an obvious resemblance to gcc/config.gcc.  The cases
# should be kept similar, to ease moving library-specific settings
# from config.gcc to this file. 


The (patched) section of "config.gcc" is (now) this:

        i[34567]86-*-darwin* | x86_64-*-darwin*)
                tmake_file="${tmake_file} i386/t-fprules-softfp
soft-fp/t-softfp"
                ;;
        i[34567]86-*-linux* | x86_64-*-linux*)
                tmake_file="${tmake_file} i386/t-fprules-softfp
soft-fp/t-softfp i386/t-linux"
                ;;
        i[34567]86-*-solaris2*)
                tmake_file="${tmake_file} i386/t-fprules-softfp
soft-fp/t-softfp"
                ;;


----------
Hmmm, Let me check something ...
# find /usr/share/src/gcc_trunk/ -name t-fprules-softfp

/usr/share/src/gcc_trunk/gcc/config/i386/t-fprules-softfp
/usr/share/src/gcc_trunk/gcc/config/rs6000/t-fprules-softfp


The code is broken (or faILs through) in "libgcc/conifg.host" (since we have no
"64" directory):

        # Provide backward binary compatibility for 64bit Linux/x86.
        if test "${host_address}" = 64; then
                tmake_file="${tmake_file} i386/${host_address}/t-softfp-compat"
        fi
----------


I am going to add this to the _end_ of "libgcc/config.host" :

case ${host} in
i[34567]86-*-solaris2*)
        if test "${host_address}" = 32; then
                tmake_file="${tmake_file} t-softfp
i386/${host_address}/t-fprules-softfp"
        else
                tmake_file="${tmake_file} i386/t-fprules-softfp
soft-fp/t-softfp"
                ;;

        fi
        ;;
esac



Building now, seems to build without breaking (thus far).
I will keep you informed and report back with the Testsuite.

Thanks,
Rob

[Bug inline-asm/39048] gcc 4.4.0 20090131 - Extra underscore hides libgcc's soft-fp functions from Testsuite causing FAILs + naming error in libgcc

[rob1weld at aol dot com]

------- Comment #8 from rob1weld at aol dot com  2009-02-07 04:21 -------
Here is: gcc 4.4.0 20090206 [trunk revision 143992] ./configured with:

../gcc_trunk/configure --enable-languages=ada,c,c++,fortran,java,objc,obj-c++
--enable-shared --disable-static --enable-multilib --enable-decimal-float
--with-long-double-128 --with-included-gettext --enable-stage1-checking
--enable-checking=release --with-tune=k8 --with-cpu=k8 --with-arch=k8
--with-gnu-as --with-as=/usr/local/bin/as --without-gnu-ld
--with-ld=/usr/ccs/bin/ld


(Notes: This error no longer occurs when I use your patch, my fix, a different
revision, and a different Linker. It is _likely_ that the error is also fixed
for the revision reported (with GNU's Linker). I needed to switch back to 
Sun's Linker to compile some Sun code that I must work on the next few days.

I searched gcc.log for the words "undefined reference" and they no longer
occur.

This patch is tested for i386-pc-solaris2.11 (OpenSolaris 2008.11 snv_101b)
when booted in 32-bit mode (on VirtualBox, on WinXP) using gcc revision 143992
using Sun's Linker (and GNU assembler version 2.19).


After this patch is tested, approved, applied to trunk, and re-tested, then
this Bug will be fixed.

We all thank us for our help,
Rob

This is not yet working on _both_ Sun and GNU's Linkers.
