Stuart Hastings 4bd3dd956f Reverting 100530 & 100531 due to regressions in the GDB test suite. 
llvm-svn: 100563
 2010-04-06 21:38:29 +00:00
Stuart Hastings c067196984 Revise debug info machinery to digest nested functions and classes. 
A certain GDB testsuite case (local.cc) has a function nested inside a
class nested inside another function.  GCC presents the innermost
function to llvm-convert first.  Heretofore, the debug info mistakenly
placed the inner function at module scope.  This patch walks the GCC
context links and instantiates the outer class and function so the
debug info is properly nested.  Radar 7426545.

Chris Lattner 28f2fdafcd hopefully sate the clang self host build, which is apparently 
instantiating some folding set stuff that GCC isn't, requiring 
some types to not be incomplete.

I don't know if clang is right or wrong, but unbreaking the
bot is goodness.  Here's the broken build:
