New Revision: 247273
URL: http://llvm.org/viewvc/llvm-project?rev=247273&view=rev
Log:
[OPENMP] Generate threadprivates as TLS variables by default.
If target supports TLS all threadprivates are generated as TLS. If target does
not support TLS, use runtime calls for proper codegen of threadprivate
variables.
