Daniel Dunbar 58a7a265cf Fix codegen of chained declarations
- Killed useless CodeGenModule::EmitGlobalVarDeclarator, instead just
   recurse on any ScopedDecl.
 - Fix for <rdar://problem/6093838>

Chris Lattner 780f329cb0 move two more lists of protocols over to use ObjCList<ObjCProtocolDecl>,
simplifying code along the way and fixing a problem and memory leak or two.

Chris Lattner 3db6cae19c introduce a new ObjCList templated class and start moving
various objc lists over to it.  First up, the protocol list 
on ObjCInterfaceDecl.

we don't push strings into LLVM IR and then have to read them back out.

Eli Friedman c134fcb0d7 For setting attributes, don't assume there are ParamVarDecls available,
because trying to access non-existent ParamVarDecls can crash. 
Testcase from the original source for PR2414.

Eli Friedman ff4a2d9e2c First cut at setting attributes for functions and calls; this puts us
much closer to passing the gcc struct layout tests.

It might be possible to refactor this a bit, but I'm not sure there's 
actually enough common code for that to be useful.

To get the calling convention completely correct, a bit of 
platform-specific code is necessary even for x86-Linux. On x86-Linux, the
alignment of function parameters is extremely strange; as far as I can tell,
it's always 4 except for SSE vectors or structs containing SSE vectors.  I'm 
continuing to investigate this.

Eli Friedman cd5f4aaf0c PR1893: Fix up the type of tentative definitions of incomplete array
types so that they end up the correct size.

Eli Friedman 77ba708819 Allow the type of a global to be different from the type of its
associated declaration. This is a prerequisite to handling
general union initializations; for example, an array of unions involving 
pointers has to be turned into a struct because the elements can have 
incompatible types.

I refactored the code a bit to make it more readable; now, the logic for 
definitions is all in EmitGlobalVarInit.

The second parameter for GetAddrOfGlobalVar is now dead; I'll remove it 
separately.

By itself, this patch should not cause any visible changes.

been used.  In preparation for the fix to PR2360, but also a minor bug 
in its own right.

2008-05-27 04:58:01 +00:00
Eli Friedman 0c99509927 Emit memmove, not memcpy, for structure copies; this is unfortunately
required for correctness in cases of copying a struct to itself or to 
an overlapping struct (itself for cases like *a = *a, and overlapping 
is possible with unions).

Hopefully, this won't end up being a perf issue; LLVM *should* be able 
to optimize memmove to memcpy in a lot of cases, and for small copies 
the generated code *should* be mostly comparable. (In reality, LLVM 
is currently horrible at optimizing memmove, but that's a bug, not a 
fundamental issue.)

gcc currently generates wrong code; that's

lib/CodeGen/CGExpr.cpp and to change include/clang/AST/Attr.h to

llvm::GlobalValue::VisibilityTypes. These changes eliminate
dependencies in the AST library on LLVM's VMCore library.

Eli Friedman be14c5c6e2 Disable the function address cache; this doesn't have any ill effects,
as far as I can tell, and it fixes code like test/CodeGen/functions.c.

(Whatever performance effect it might have, crashing on a 
construct like this isn't really acceptable; I've run into this 
multiple times.)

Chris Lattner 5827754da1 remove the 'unused static' diagnostic from codegen. This should be

Steve Naroff 248a753f6b Remove FileVarDecl and BlockVarDecl. They are replaced by VarDecl::isBlockVarDecl() and VarDecl::isFileVarDecl().
This is a fairly mechanical/large change. As a result, I avoided making any changes/simplifications that weren't directly related. I did break two Analysis tests. I also have a couple FIXME's in UninitializedValues.cpp. Ted, can you take a look? If the bug isn't obvious, I am happy to dig in and fix it (since I broke it).

Chris Lattner ce5605ecf7 some cleanups on top of David's patch. There are still two
remaining open issues I've communicated to him:

1) self can be assigned to, and his patch didn't handle it correctly.
2) CollectObjCIvarTypes is N^2 (because each subclass reprocesses
   all parent class ivars) and flattens classes.  If A derives from B, 
   and both have an int, I'd expect to get { {i32}, i32}, not { i32, i32}.

David, please review.

Chris Lattner bda0b626e7 Make a major restructuring of the clang tree: introduce a top-level
lib dir and move all the libraries into it.  This follows the main
llvm tree, and allows the libraries to be built in parallel.  The
top level now enforces that all the libs are built before Driver,
but we don't care what order the libs are built in.  This speeds
up parallel builds, particularly incremental ones.
