From e0426047cb684842700f0098f74842a38260dbae Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Thu, 23 Nov 2006 00:46:45 +0100 Subject: [POWERPC] Make xmon disassembly optional While adding spu disassembly support it struck me that we're actually carrying quite a lot of code around, just to do disassembly in the case of a crash. While on large systems it's not an issue, on smaller ones it might be nice to have xmon - but without the weight of the disassembly support. For a Cell build this saves ~230KB (!), and for pSeries ~195KB. We still support the 'di' and 'sdi' commands, however they just dump the instruction in hex. Move the definitions into a header to clean xmon.c just a tiny bit.
