Have you tried -masm=intel? I've only gone as far as seeing that it generates intel-style asm from C/C++. I decided that it was better to follow the "when in Rome..." rule. The syntax issue seems arbitrary to me. I've used lots of assemblers. They're all different. For several years in the 1980s I had contracts with two companies that used different chips. One assembler used source,destination and the other destination,source. I would work with one in the morning, the other in the afternoon. Just had to be careful. Bob
