[Gems-users] ATMTP "unrecognized instruction" error

[Nikos Anastopoulos <anastop@xxxxxxxxxxxxxxxxx>]

Hi,
we are trying to use ATMTP to evaluate some TM code. We are building our 
binaries on a Niagara system using Sun Studio 12 (cc 5.9 SunOS_sparc 
2007/05/03 ). We compiled with -m64 -mt -Wc,xarch=v9 , as specified in 
the rock-tm-test Makefile.
However, in contrast to the rock-tm-test example, our program crashes with:

 2 ERROR!!! tlb miss on unrecognized inst: d302a004 CPS bits not set

We used gdb and found out that this corresponds actually to a "ld" 
instruction. In Rock.h, only ldsb, ldsh, ldsw, ldub, lduh, lduw, ldx 
instructions are defined. Another "ld" instruction in the same part of 
the code gives an lduh opcode when masked with MEM_OP_MASK. However, the 
ld instruction in question, when masked with MEM_OP_MASK gives 
0xc1000000, which is not defined in Rock.h and thus we get the 
"unrecognized inst." error. Moreover, we found an "st" instruction which 
again when masked with MEM_OP_MASK gives 0xc1200000, which will result 
in an "unrecognized inst".
Has anyone experienced a similar problem? Could it be a problem with the 
version of our compiler? Are we missing something in the setup process?
Thanks in advance.

Kind regards,

Nikos.
