I came across the following code snippet (well, there was a bit more but I've trimmed it down):
li v0, 0x350 mult v1, side, v0 jr ra addu v0, v0, v1
Ghidra incorrectly gives (iParam1 * 0x350) >> 0x20 + 0x350, where the correct result would not have the right shift.
(iParam1 * 0x350) >> 0x20 + 0x350
I was able to reproduce this with a small file just containing the above four instructions, which I've given here: a-minimal-example.zip.
