#20 (1.6.0) Problems with little endian model - Nios2

[Guilherme Melo]

I'm using a x86/linux machine.
I'm trying to execute the programs of acstone benchmark.

Initially I used Altera's compiler and assembler.
The elf files generated by Altera's assembler are
little endian. When I try to execute the program in a
interpreted simulator I get the following output:

When I use the assembler generated by ArchC i get this
output:

I checked this binary file and it's a big endian, but
the model is little endian. Why the assembler generates
a big endian file?

So I tryed to set the model to big endian e it worked
for that files generated by ArchC assembler, but it
should work also as little endian.

Indeed... the assembler on version 1.6.0 of the ArchC
package had some issues to generate little endian objects
files. Those were fixed on the 2.x series.
Are you planning to migrate to the 2.x series?

Well, I was not planning to migrate to 2.x now.
I don't know how much effort I would need to migrate
and I don't have much time to finish this model.
Meanwhile I will use the model as big endian.
