  All it needs is funding. :-) What GDB needs is expect, not Tcl. Most
of the GDB testsuite is just expect pattern matching from the shell.
That's the entire reason I choose Tcl as it already had expect support.
Expect was necessary functionality for GDB testing. For GCC &  Binutils,
Expect is only used for remote testing support.

  As it's possible to embed Tcl in other programs, the idea was to use
an embedded Tcl interpreter when needed during a transition period. It's
mostly just the framework itself that would need to be refactored into
Python. There is also a large amount of code in gcc/testsuite that
should probably be in core DejaGnu too. That would be a large component
in analyzing existing code to write a true design doc. The best part is
now we have large toolchain testsuites to use to test DejaGnu changes.

 A one point we thought DejaGnu would be used for other projects, but I
think it's obviously that these days it's  only used for GNU toolchain
testing.

  I'm making progress on setting up a development environment to test
patches. I use my ABE tool to build toolchains, had to fix some bugs
(and add PI support) first.
