Chris Lattner e64d7ba153 Update to match mainline ConstantStruct::get API change. Also, use
ConvertType on InitListExprs as they are being converted.  This is
needed for a forthcoming patch, and improves the IR generated anyway
(see additional type names in testcases). 

This patch also converts a bunch of std::vector's in CGObjCMac to use
C arrays.  There are a ton more that should be converted as well.

Douglas Gregor 61226d3fcf When determining whether we can make a declaration into a global
constant, also consider whether it's a class type that has any mutable
fields. If so, it can't be a global constant.

John McCall f9b056b002 After much contemplation, I've decided that we probably shouldn't "unique"
__block object copy/dispose helpers for C++ objects with those for
different variables with completely different semantics simply because
they happen to both be no more aligned than a pointer.

Found by inspection.

Also, internalize most of the helper generation logic within CGBlocks.cpp,
and refactor it to fit my peculiar aesthetic sense.

John McCall a738c25f5e Use the "undergoes default argument promotion" bit on parameters to
simplify the logic of initializing function parameters so that we don't need
both a variable declaration and a type in FunctionArgList.  This also means
that we need to propagate the CGFunctionInfo down in a lot of places rather
than recalculating it from the FAL.  There's more we can do to eliminate
redundancy here, and I've left FIXMEs behind to do it.

llvm-svn: 127174
2011-03-07 21:53:18 +00:00
Devang Patel d6ffebb077 DebugInfo can be enabled or disabled at function level (e.g. using an attribute). However, at module level it is determined by command line option and the state of command line option does not change during compilation. Make this layering explicit and fix accidental cases where the code generator was checking whether module has debug info enabled instead of checking whether debug info is enabled for this function or not.

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 bf9a86b50f Don't call objc_read_weak as part of emitting a block literal.
Nobody ever gave me a clear reason for why we were doing this, and
now it's apparently causing serious problems, so if *not* having this
causes problems, we get to solve them the right way this time.

John McCall e3dc1707b5 Assorted cleanup:

John McCall b0a3ecb41c Extend the const capture optimization to C++ record types with no

llvm-svn: 125021
2011-02-07 18:37:40 +00:00
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.

Peter Collingbourne 0ff0b37627 Move name mangling support from CodeGen to AST. In the
process, perform a number of refactorings:

- Move MiscNameMangler member functions to MangleContext
- Remove GlobalDecl dependency from MangleContext
- Make MangleContext abstract and move Itanium/Microsoft functionality
  to their own classes/files
- Implement ASTContext::createMangleContext and have CodeGen use it

No (intended) functionality change.

John McCall 3882ace207 Refactor the application of type attributes so that attributes from
the declaration-specifiers and on the declarator itself are moved
to the appropriate declarator chunk.  This permits a greatly
simplified model for how to apply these attributes, as well as
allowing a much more efficient query for the GC attribute.
Now all qualifier queries follow the same basic strategy of
"local qualifiers, local qualifiers on the canonical type,
then look through arrays".  This can be easily optimized by
changing the canonical qualified-array-type representation.

Do not process type attributes as decl attributes on declarations
with declarators.

When computing the type of a block, synthesize a prototype
function declarator chunk if the decl-spec type was not a
function.  This simplifies the logic for building block signatures.

Change the logic which inserts an objc_read_weak on a block
literal to only fire if the block has a __weak __block variable,
rather than if the return type of the block is __weak qualified,
which is not actually a sensible thing to ask.

John McCall 7decc9e4ea Calculate the value kind of an expression when it's created and
store it on the expression node.  Also store an "object kind",
which distinguishes ordinary "addressed" l-values (like
variable references and pointer dereferences) and bitfield,
@property, and vector-component l-values.

Currently we're not using these for much, but I aim to switch
pretty much everything calculating l-valueness over to them.
For now they shouldn't necessarily be trusted.
