This patch allows clang to compile the "extern" storage class in OpenCL 1.2.
I've also added a test case for the issue.
Does clang only complain if you use extern with constant address space
variables? Because it looks like extern is already handled in
DeclSpec::SetStorageClassSpec()
-Tom
It seems like it doesn't. If I try:
extern float foo;
void __kernel test_fn(__global float *out)
{
out[0] += foo;
}
clang -cc1 -x cl -cl-std=CL1.2 -o test.ll test.cl
I receive the following error:
test.cl:1:14: error: program scope variables are required to be
declared in constant address space
extern float foo;

1 error generated.
