The existing definition is nonsense - I won't guess how it happened, but there's no reason to keep it. Thiemo has MIPS Technologies' thanks and blessing in making this change. Please let our Nigel Stephens know when it's done (mailto:nigel@mips.com) and he'll double-check it. I'm sure you'll put comments in the code noting that this is different from the document. There's a more tricky question, which is how we're going to document this. I'm currently trying to create a more user-friendly (and accurate) ABI document, but had not yet got to the relocation types... -- Dominic Sweetman, MIPS Technologies (UK) The Fruit Farm, Ely Road, Chittering, CAMBS CB5 9PH, ENGLAND phone: +44 1223 706205 / fax: +44 1223 706250 / swbrd: +44 1223 706200 http://www.mips.com
