Automatic cast off "union tree" in gdb

[k e]

Hi, When stepping through gcc with gdb: is there a way
 to be able to make gdb automatically cast a "union tree" to the
 correct struct depending on the union tree's type?  A "p "
  will print out all unions. I'd not want to do a cast all the time.

Not that I know of.

I think most developers use debug_tree for this.  There are some gdb
convenience commands defined in gcc/gdbinit.in (which is made into a
real .gdbinit during the build) -- use these.  And, I recommend
reading the debugging tips page on the wiki.
