I used 'xgcc' to indicate 'alphaev67-unknown-linux-gnu-gcc'. It should be picked up from the same path as your assembler (alphaev67-unknown-linux-gnu-as) earlier. > > I ended up using the the Makefile in util/m5 (makefile.alpha) and > setting the path of CrossCompile to the Alpha precompiled cross > compiler obtained from the M5 wiki: > > http://www.m5sim.org/dist/current/alphaev67-unknown-linux-gnu-x86-32.tar.bz2 > > and changed the name of assembly file to have a .S suffix. > > There really is no harm in using a .S suffix right, so my approach > should be fine in the long run? > > My other question is as follows: > > When running it, I get the following output: > > Global frequency set at 1000000000000 ticks per second > 0: system.remote_gdb.listener: listening for remote gdb #0 on port 7000 > **** REAL SIMULATION **** > info: Entering event queue @ 0.

There is a small test program, 'hello.c', in tests/test-progs/hello/src directory in the M5 tree that just outputs "Hello world!" on the standard output. If you compile that program and simulate its executable, you'll be able to verify if the program is being simulated correctly or not. Various precompiled binaries for that source program are already present in the tests/test-progs/hello/bin directory. > > Malek > -Soumyaroop > On Tue, Jun 22, 2010 at 4:56 PM, Gabriel Michael Black > <gbl...@eecs.umich.edu> wrote: >> You're probably confusing our loader which is likely making more assumptions >> than it should about how a binary is put together.
