[Bug 389734] [NEW] the value of the register $sp xspim is readonly

[Arton Pereira Dorneles]

Public bug reported:

Binary package hint: spim

Ubuntu Version =  9.04
Spim Version = 7.4-0ubuntu1 i386
Processor = Intel(R) Core(TM)2 Duo CPU  E8500

Version 7.4 presents problems to change the value of register $sp.
The version 7.3 is working

Here is a snippet of code and the expected result:

  # The initial value of $sp = 70000;
  addi $sp, $sp, 4 # After this line $sp = 70004

  li $a0, 20 # and after this line ... $sp = 70000 again! There is a bug
here

I looked at the official site of the author and the last version is 7.3
who created the version 7.4?

Attached is an assembly code to reproduce the bug
