Subject: PowerPC assembler question
Date: Mon, 10 Jun 2013 09:01:35 +1000 [thread overview]
Message-ID: <20130610090135.a002eba2401c06eedfa7b7ec@mega-nerd.com> (raw)
Hi all,
I'm trying to fix a problem in the PowerPC backend of the Glasgow
Haskell Compiler (GHC) and have a problem with the following
instruction form:
lwz 30, .label - (1b)(31)
Reading the documentation I could find, I have figured out that this
loads a 16 bit value into register 30. How it calculates that 16 bit
value has got me somewhat flumoxed.
Anybody care to explain?
Cheers,
Erik
