Here is the source for the DICE-linker libraries for ReqTools. Originally written by Jan van den Baard, with some (?) bugfixes and changes by Magnus Holmgren. The DMakeFile (that requires DMake 2.0) generates all flavours of the library, named: reqtoolss.lib ; Small data, stack arguments reqtoolssr.lib ; Small data, register arguments reqtoolsl.lib ; Large data, stack arguments reqtoolsrl.lib ; Large data, register arguments Assembly was done with GenIm2 (Devpac 2.14), as Das simply lacks some features that were needed to make the source simpler (would need twice as many source files if Das was used...). Should work with most macro-assemblers, that generates linkable code, supports xxx(a4) addressing for "normal" labels (i.e. smalldata model), and can define equates on the command line.
