I am building an implementation of MIPS on an FPGA and am using GCC 4.5.0 with
binutils 2.20 to generate code for it. The processor does not exhibit branch or
load delay slots.
For debugging purposes, I am using the 'break' opcode but gcc does not know
this. As a result, i am using inline assembly to insert the opcode.
Put simply, when I use an __asm__ volatile ("break") line, GAS ignores the fact
that there are no branch delay slots when assembling that function.
Attached is a test case demonstrating the bug
