Error 33 is a warning now. * v0.2 (25.03.97) phx * Writes ELF object for 32-bit PowerPC big-endian. Either absolute * or ELF output format may be selected. ELF is default for all * currently supported platforms. PPCasm supports nine different * relocation types (there are much more...). * Compiles and works also under NetBSD/amiga (68k). * Changed function declaration to 'new style' in all sources * (to avoid problems with '...' for example). * Warnings can be disabled. * v0.1 (11.03.97) phx * First test version with all PowerPC instructions and most * important directives. Only raw, absolute output. * v0.0 (14.02.97) phx * File created.
