Re: [Gems-users] Compiling problems with transaction.c in Gems 2.0

["Rubén Titos" <rtitos@xxxxxxxxxxx>]

Luke and Jayaram,

Using the 'as' assembler in /usr/ccs/bin seems to have solved the problem. 

Thanks a lot!

Ruben

P.S.: Just for the record, this is the gcc build I used: 

bash-3.00#
 gcc -v
Reading specs from /usr/local/lib/gcc/sparc-sun-solaris2.10/3.4.6/specs
Configured with: ../configure --with-as=/usr/ccs/bin/as --with-ld=/usr/ccs/bin/ld --enable-shared --enable-languages=c,c++,f77
Thread model: posix
gcc version 3.4.6

Ruben,

My guess is that this could be
- a bug in gnu assembler (gas) or
- a bug in gcc or
- bad inline assembly.

To rule out the first two cases, could you recompile with a different
version of gcc / configured to use a different assembler (preferably
'as'). We have
successfully compiled the TM workloads using the following gcc build...

Configured with:
/gates/sfwnv/builds/sfwnv-gate/usr/src/cmd/gcc/gcc-3.4.3/configure
--prefix=/usr/sfw --with-as=/usr/ccs/bin/as --without-gnu-as
--with-ld=/usr/ccs/bin/ld --without-gnu-ld --enable-languages=c,c++,f77
--enable-shared
Thread model: posix
gcc version 3.4.3 (csl-sol210-3_4-20050802)

We have also had problems compiling with the following gcc setup (i
think it uses 'gas')-

Target: sparc-sun-solaris2.10
Configured with:
/export/home/bldmstr/nightly/20060207_gcc2ir.s10.opt.tarbuild/src/configure
--prefix=/opt/gcc --enable-languages=c,c++
Thread model: posix
gcc version 4.0.2 (gccfss)
