Chris Lattner 445fcabff7 Alternate address spaces work: 
rename QualType::getQualifiers to getCVRQualifiers.
Add some fixme's and clean up some code relevant to qualifiers.
Change ASQualType to contain a Type* instead of a QualType.  
Any CVR qualifiers should be on the outer qual type.

Eli Friedman bd258284e0 Split out incomplete arrays from VariableArrayType into 
IncompleteArrayType.  This should make code dealing with both incomplete 
and variable length arrays much more readable, plus it allows properly 
making the distinction between isVariableArrayType() and 
isVariablyModifiedType().  The patch is a little big, but it's 
strightforward. so I don't think there should be any issues.

 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.

Chris Lattner 68be60694e sink more of the type related code into CodeGenTypes.

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 :)

Christopher Lamb 7d303b2a20 Better match llvm-gcc's behavior for CodeGen naming of anonymous structs and unions. 
llvm-svn: 44490
 2007-12-01 09:20:34 +00:00
Christopher Lamb b0e6094a22 When generating the CodeGen type name of a struct, union, enum use the typedef 
name if a tag type name is not available for the type. This matches how llvm-gcc 
chooses CodeGen type names.

This means that "typedef struct {...} foo" now results in a CodeGen name of 
"struct.foo" rather than "struct."

Devang Patel e11664a0ef Rename classes and collections that maintain record layout information. 
Now, at AST level record info is maintained by ASTRecordLayout class.
Now, at code gen  level record info is maintained by CGRecordLayout class.
