Dear all,
I added flag to generate run time trace files in Alpha full system simulation.
As far as I know, there should
be only 32 integer architecture registers in Alpha ISA. But in the trace file,
there are instructions
using r39, r36, r37, and so on. Does anyone notice the same thing? Is it
possible they are float point
registers, and the trace file does not print out well?
Best,

Hi,
I am actually using O3 mode. The strange thing is there are both f0, f1, f3 and
r36, r37, r39, and so on the the trace file generated by SPEC2006 INT
benchmarks. They should not be physical registers because I see the WAW
dependencies in the trace file frequently.
It might help if you can post the command used to generate the trace (the
flags used are the most important) and a sample instruction trace that you
think is not correct / unexpected.
