Eric Christopher b2db8e47e2 Constify the getClassName routine and variables that come out of it, 
and then use it for forward decl names.

Part of rdar://10209967 and rdar://10400981

Eric Christopher ee4ab93906 For pass-by-value record arguments to functions emit a forward decl 
instead of the entire class definition.

Eric Christopher 980df5d7ec Typo. 
llvm-svn: 148903
 2012-01-25 02:06:52 +00:00
Eric Christopher 45c4d47b8a When adding types to the context chain for record types, just emit 
a forward declaration unless we already have a type. We can fill it in
later if it's actually used.

Fixes PR11345

Eric Christopher cd88813dbf When in a limited debug information situation if we can find the original 
declaration for the type then go ahead and use that, it's still smaller
than creating an all new derived type.

Nick Lewycky 2219ef0b68 Minor cleanup, mostly reindenting. Remove one helper function that just called 
the other helper functions, since we already differentiated the cases it was
testing between. No functionality change.

Eric Christopher 7cdf948601 Recommit: 
Start handling debug line and scope information better:

    Migrate most of the location setting within the larger API in CGDebugInfo and
    update a lot of callers.
    Remove the existing file/scope change machinery in UpdateLineDirectiveRegion
    and replace it with DILexicalBlockFile usage.

    Finishes off the rest of rdar://10246360

after fixing a few bugs that were exposed in gdb testsuite testing.

Richard Smith caf3390d44 Constant expression evaluation refactoring: 
- Remodel Expr::EvaluateAsInt to behave like the other EvaluateAs* functions,
   and add Expr::EvaluateKnownConstInt to capture the current fold-or-assert
   behaviour.
 - Factor out evaluation of bitfield bit widths.
 - Fix a few places which would evaluate an expression twice: once to determine
   whether it is a constant expression, then again to get the value.

Eli Friedman 0dfb889575 Support for C1x _Atomic specifier (see testcase). This is primarily being committed at the moment to help support C++0x <atomic>, but it should be a solid base for implementing the full specification of C1x _Atomic. 
Thanks to Jeffrey Yasskin for the thorough review!

Eric Christopher e655657c94 Call UpdateLineDirectiveRegion every time we want to emit a stop 
point in the code. Ensures that we don't miss any places and the
check is reasonably cheap.

Chris Lattner 01cf8db38b now that we have a centralized place to do so, add some using declarations for 
some common llvm types: stringref and smallvector.  This cleans up the codebase

John McCall 147d021b75 Emit the structure layout of the block literal parameter to a block 
invocation function into the debug info.  Rather than faking up a class,
which is tricky because of the custom layout we do, we just emit a struct
directly from the layout information we've already got.

Also, don't emit an unnecessarily parameter alloca for this "variable".

John McCall 351762cda2 A few more tweaks to the blocks AST representation: 
- BlockDeclRefExprs always store VarDecls
  - BDREs no longer store copy expressions
  - BlockDecls now store a list of captured variables, information about
    how they're captured, and a copy expression if necessary
    
With that in hand, change IR generation to use the captures data in       
blocks instead of walking the block independently.        

Additionally, optimize block layout by emitting fields in descending
alignment order, with a heuristic for filling in words when alignment
of the end of the block header is insufficient for the most aligned
field.

Devang Patel 91bbb5547d Introduce -flimit-debug-info. 
In this experimental mode try avoiding debug info emission for classes as much as possible. The goal is to reduce size of produced debuginfo without reducing quality of debug info in general. This is a work in progress.
