Test code as following:# ====================================

.set noat

_start:

movia at,((90000000+57600)/115200)

movia at,((90057600)/115200)

.end# ====================================

I got these result:

[NIOS2 GNU Shell]$ nios2-elf-gcc -c -o test.o test.S

[NIOS2 GNU Shell]$ nios2-elf-objdump -S test.o

test.o: file format elf32-littlenios2

Disassembly of section .text:

8: 00400034 movhi at,0

c: 0840c354 ori at,at,781

[NIOS2 GNU Shell]$

Why?
