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

["Rubén Titos" <rtitos@xxxxxxxxxxx>]

Dear list,

I've just set up my gems-2.0 environment and I'm trying to compile the transactional microbenchmarks included in the new release. After having the files inside my simulated simics machine (a sarek US-III+ with Solaris 10), my problem is that I can't build any benchmark (nor any other workload) since, according to the assembler,  there's an error in the code generated when compiling the file $GEMS/microbenchmarks/transactional/common/transaction.c. I've compiled it in two steps to see the assembler code, and to my surprise, the assembler finds an "Illegal operand" error in an empty line. Here is the output I got inside my sarek/sol10 simics machine, and some lines from 
transaction.s:

I'm using Solaris 10 "out-of-the-box", and gcc/gas included in /usr/sfw.

bash-3.00# gcc -v
Reading specs from /usr/sfw/lib/gcc/sparc-sun-solaris2.10/3.4.3/specs
Configured with:
/gates/sfw10/builds/sfw10-gate/usr/src/cmd/gcc/gcc-3.4.3/configure
--prefix=/usr/sfw --with-as=/usr/sfw/bin/gas --with-gnu-as
--with-ld=/usr/ccs/bin/ld --without-gnu-ld --enable-languages=c,c++
--enable-shared
Thread model: posix
gcc version 3.4.3 (csl-sol210-3_4-branch+sol_rpath)

Anybody knows what's going on? Could it be a bug in the inline assembly code of transaction.c? 

Thanks a lot!

Ruben
