? How will that work for something like
struct X {int a:5, :8, c:12,:7; float d;} x;
Usually you can convert bitfields ops to operations under masked -- what the
compiler has to do. So reading x.c becomes ((x.i>>7)&0xfff) etc. Where x.i
represents the same word where a &c are stored. I thought that (except for pcc)
bitfields code gen & performance issues got fixed a long time ago?
