--- Comment #7 from jbeulich at suse dot com --- For the problem originally reported here (operator name space collision) a workaround could be introduced (e.g. a new operand to .intel_syntax to allow suppressing the recognition of MASM-like operands). I don't, however, see any option for register names (besides ".intel_syntax prefix" of course, but aiui this wouldn't work with the output gcc produces, and of course this mode isn't really "Intel Syntax" anymore anyway).
