2010-04-06Revise debug info machinery to digest nested functions and classes.Stuart Hastings
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.

2010-04-02Switch the code generator (except the JIT) onto the new DebugLocChris Lattner
representation. This eliminates the 'DILocation' MDNodes for file/line/col tuples from -O0 -g codegen. This remove the old DebugLoc class, making it a typedef for DebugLoc, I'll rename NewDebugLoc next. I didn't update the JIT to use the new apis, so it will continue to work, but be as slow as before. Someone should eventually do this or, better yet, rip out the JIT debug info stuff and build the JIT on top of MC. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100209 91177308-0d34-0410-b5e6-96231b3b80d8
