------- Additional Comments From sabre at nondot.org  2004-03-16 02:53 -------
This is now implemented.  Primary patch here:
http://mail.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20040315/013179.html

Testcases here:
test/Regression/CFrontend/2004-03-15-SimpleIndirectGoto.c
test/Programs/SingleSource/Regression/C/2004-03-15-IndirectGoto.c 

Note that this does not work correctly in the presence of exceptions and C++
cleanups, but then again, neither does the native GCC compiler.

This GCC extension is widely used to implement "threaded interpreters", so
supporting it is useful. :)
