Subject: [openrisc] Difference Between Jump(l.j) and Jump and Link (l.jal)
Hi Everyone,
What exactly is the difference between Jump and link and the Jump
instruction? Don't they both do the same thing (according to the
OpenRISC architecture manual where it says "32 Bit Implementation").
For Example, let's say we have
100C: l.j 103233
1010: addi r3,r0,0x2
1014: ori r3,r11,0x0
and
100C: l.jal 103233
1010: addi r3,r0,0x2
1014: ori r3,r11,0x0
both of then should write 2 into R3 before jumping to 103233 and the R9
for both the jumps will be set to 1014.. am I correct?
Any Help is appreciated.
Thanks,
Balaji V. Iyer.
