Dear sir/madam, I am a student in Yale University and I use your SimpleScalar tool for doing my research. but I have some problems. Do you mind if I ask you my question? I appreciate your help. I want to use alpha instruction set for simplescalar. I have done config-alpha and it works but I want to compile also my c testcases to alpha binaries to use it with sim-out order. I tried install gcc 3.1 and binutils 2.12 but binutils fails because of this error: "coff-alpha.c:1455: error: invalid lvalue in assignment" would you please tell me which version of binutils and gcc I should install to be able to generate alpha binaries suitable for simplescalar and if they have some bugs for installation is there any document or patch to remove the bugs? Thanks in advance, Naghmeh
