Dan Gohman 922096cc5e Adjust for the API change to APInt::getBitsSet. 
People more familiar with clang than me, please review this.

Chris Lattner c9b96ae832 strings are arrays too

Eli Friedman f54c4e5fea A couple of minor fixes to aggregate codegen, to stop asserting on some 
edge cases.

 2008-02-11 01:09:17 +00:00
Eli Friedman a5b2023810 Make unsupported constant exprs fail with a warning instead of crashing 
codegen.

 2008-02-11 00:23:10 +00:00
Chris Lattner 36fc8790b7 Fix PR1992 by computing the right type for string literals, which 
is an array type not a pointer type.  This requires updating some
diags that change and updating the code generator to handle the
proper form of strings.

Eli Friedman a62f3e1352 Expose the logic for field address codegen; it is needed for aggregate 
initializers, and I don't want to duplicate the bitfield-handling code.  
(I'll send a patch for aggregate initializers to the mailing 
list sometime soon.)

Chris Lattner b818af539f now that ConvertTagDeclType is nice and simple, use it from UpdateCompletedType.

 2008-02-06 06:06:49 +00:00
Chris Lattner d11482ea22 simplify and speed up type refinement logic. No functionality change. 
llvm-svn: 46808
 2008-02-06 06:03:51 +00:00
Chris Lattner a64dde6b48 only convert the type name once, not each type it is refined.

Chris Lattner ee9fafd533 split tagged decl layout into its own method. 
llvm-svn: 46803
 2008-02-06 05:18:32 +00:00
Chris Lattner f6e3669eb2 only update the llvm type for a struct when we used the struct 
previously in an opaque context.  If we didn't do this, 
computing its layout could be wasted: just be lazy.

llvm-svn: 46802
 2008-02-06 05:12:09 +00:00
Chris Lattner 68be60694e sink more of the type related code into CodeGenTypes.

 2008-02-06 05:08:19 +00:00
Chris Lattner 8b945ee058 codegen static variables in a function into a different namespace from 
static variables outside functions.

 2008-02-06 04:54:32 +00:00
Chris Lattner a5e4d30942 Finish off the refactoring of type handling stuff. Now we recompile every 
tag decl after it has been completed

llvm-svn: 46798
 2008-02-06 04:51:19 +00:00
Chris Lattner adf1f51fc5 move the codegen ASTConsumer out of the driver into libcodegen, 
eliminating a bunch of forwarding methods and generally 
simplifying things.

Chris Lattner b1537ebdd4 rewrite some of the type refinement code to eliminate dangling pointers 
simplify the code and generally make it more robust.

llvm-svn: 46745
 2008-02-05 08:06:13 +00:00
Chris Lattner 86964a9653 Change the key of CGRecordLayouts from being an llvm type* to being a decl*. LLVM 
Type*'s can change as types are refined, so we can't use them as a stable key in
the map.  Decls don't change, so use them instead.

This patch was written by Anders, but he's too shy to commit it himself :)

 2008-02-05 01:40:48 +00:00
Christopher Lamb 025b5fb883 Add experimental support for address space qualified types. Address space 
qualifiers use the __attribute__((address_space(id))) syntax.

llvm-svn: 46691
 2008-02-04 02:31:56 +00:00
Chris Lattner 6cba8e9d66 minor tweak to anders patch: (only) ocu vectors support splatting, but 
ocu vectors should not treat bitcasts from int <-> vector as a splat
unless it is of the element type.

llvm-svn: 46664
 2008-02-02 04:51:41 +00:00
Chris Lattner ce6ae5cb06 fix codegen on static variables which have multiple decl nodes. These 
should be merged just like normal globals.  This fixes this testcase
that Anders provided:

static struct s a;
static struct s *ap1 = &a;
static struct s a =  { 10 };

llvm-svn: 46661
