------- Comment #2 from dlenski at gmail dot com 2008-09-24 17:43 ------- Hi Andrew, It seems to me that these modifiers are quite necessary for flexible x86 assembly. What is the point of the "q" and "Q" constraints if there's no way to specifically refer to the 16-bit or 8-bit components of the selected register?
And are you sure there built-in functions to invoke the rol/ror/xhcg instructions? I don't see any in the 4.3 docs. Dan -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37621
