That syntax has been deprecated. If libdisasm is still printing that, it's a bug. The preferred syntax is stda fregrd, regrs2, [regrs1] imm_asi See, UA-2005 7.96, http://opensparc-t1.sunsource.net/specs/UA2005-current-draft-HP-EXT.pdf The original assembly language syntax for a Partial Store instruction (“stda fregrd, [regrs1] regrs2, imm_asi”) has been deprecated because of inconsistency with the rest of the SPARC assembly language. Over time, assemblers will support the new syntax for this instruction. In the meantime, some existing assemblers may only recognize the original syntax. > I believe the ASI's are 0xc0-0xc5 and 0xc8-0xcd. Right.
