           Summary: 2007-06-15-AnnotateAttribute.c does not show local
                    variable annotations
           Product: new-bugs
           Version: 2.9
          Platform: PC

            Status: NEW
          Severity: normal
          Priority: P

llvm/test/FrontendC/2007-06-15-AnnotateAttribute.c has a comment that reads:
// RUN: %llvmgcc -S %s -o - | grep llvm.global.annotations
// RUN: %llvmgcc -S %s -o - | grep llvm.var.annotation | count 3 

When I run the following I get no output of any kind:
"clang -emit-llvm -S 2007-06-15-AnnotateAttribute.c -o - | grep
llvm.var.annotation"

The following does seem to function correctly:
"clang -emit-llvm -S 2007-06-15-AnnotateAttribute.c -o - | grep
llvm.global.annotation"

It outputs:
@llvm.global.annotations = appending global [2 x { i8*, i8*, i8*, i32 }] [{
i8*, i8*, i8*, i32 } { i8* bitcast (i32* @main.a to i8*), i8* getelementptr
inbounds ([20 x i8]* @main.a1, i32 0, i32 0), i8* getelementptr inbounds ([31 x
i8]* @.str, i32 0, i32 0), i32 20 }, { i8*, i8*, i8*, i32 } { i8* bitcast (i32*
@X to i8*), i8* getelementptr inbounds ([20 x i8]* @X3, i32 0, i32 0), i8*
getelementptr inbounds ([31 x i8]* @.str4, i32 0, i32 0), i32 7 }], section
"llvm.metadata"

I attached the output of 
"clang -emit-llvm -S 2007-06-15-AnnotateAttribute.c"
