Rafael Espindola 67c6ab8865 Change CodeGen to use .loc directives. This produces a lot more readable output 
and testing is easier.  A good example is the unknown-location.ll test that
now can just look for ".loc 1 0 0".  We also don't use a DW_LNE_set_address for
every address change anymore.

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:

 2010-04-04 07:48:20 +00:00
Chris Lattner 915c5f9862 Switch the code generator (except the JIT) onto the new DebugLoc 
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.
