Hi, I want to use my cross compiler for ALPHA. I've been happy to use the pre-build gcc, gcc-4.3.2, glibc-2.6.1 (NPTL,x86/64) <http://www.m5sim.org/dist/current/alphaev67-unknown-linux-gnu.tar.bz2>. By the way, I need to build my own cross compiler for extending some instructions.
I built alphaev67-unknown-linux-gnu-gcc with crosstools-ng-1.15.0, then run a simple binary on Gem5. Then, Gem5 shows messages like below.: Global frequency set at 1000000000000 ticks per second warn: DRAM device capacity (8192 Mbytes) does not match the address range assigned (512 Mbytes) 0: system.remote_gdb.listener: listening for remote gdb #0 on port 7000 **** REAL SIMULATION **** info: Entering event queue @ 0. Starting simulation... info: Increasing stack size by one page. panic: Tried to access unmapped address 0. @ tick 7130500 [invoke:build/ALPHA/arch/alpha/faults.cc, line 217] Memory Usage: 618224 KBytes Program aborted at cycle 7130500 Aborted (core dumped) I think I need some patches for linux kernel. Does anyone know how to build my own cross compiler for ALPHA?
