Rich, I grabbed a copy of the pre-alpha version. I don't have enough time to get this version of gas to work. Instead, I just added the opcodes to gas version 1.38.1. According to my manual, there are errors in the "m68k.h" file from the gas-1.92.2 kit. The opmode field is incorrect on many of the 68040 instructions: Should be gas-1.92.2 fsadd 62 32 fdadd 66 36 fsdiv 60 30 fddiv 64 34 fsmul 63 33 fdmul 67 37 fssub 68 38 fdsub 6C 3c fsmove 40 00 fdmove 44 00 I have contacted Motorola about the problems with the documentation with the fsabs and fdabs instructions. I will send you mail when they tell me the proper bit pattern to generate these instructions. Just as a comment: Can the build process for gas be set up so that it is possible to set a default target? I am primarily interested in supporting the 040 target, but I don't want to pass the target option to gas. Bruce Lutz
