Oliver Hunt a96fe8d5c5 Add support for __builtin_expect which is needed for assert, 
among other things.

Also change a codegen warning to dump to stderr so it doesn't
mess with -emit-llvm output

llvm-svn: 44497
 2007-12-02 01:03:24 +00:00
Oliver Hunt aefc8fd415 Support initalisers for more than just int-typed static variables. 
We now use the CodeGenModule logic for generating the constant 
initialiser expression, so happily further initialiser fixes should 
automatically work for statics as well.

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."

llvm-svn: 44489
