Oct 25, 2016 at 22:04 comment added supercat Another problem with trying to simplify the source tree at parsing time is that there are many situations where a bit of syntax should not generate any code but should affect what optimizations are allowed. If foo and moo are pointers to different structure types, both of which have field bar as part of their initial sequence, writing *&foo->bar and reading *&moo->bar should result in the read seeing the write, since the only effective type used in either access is the type of bar. GCC, however, seems to filter out the *& and thus percolates the types of foo and moo...
