From fa785cb22d50c657eb08c762d627cd6aa96982f3 Mon Sep 17 00:00:00 2001 From: Jan Wen Voung Date: Fri, 8 Mar 2013 22:56:31 +0000 Subject: Disable statistics on Release builds and move tests that depend on -stats. Summary: Statistics are still available in Release+Asserts (any +Asserts builds), and stats can also be turned on with LLVM_ENABLE_STATS. Move some of the FastISel stats that were moved under DEBUG() back out of DEBUG(), since stats are disabled across the board now. Many tests depend on grepping "-stats" output. Move those into a orig_dir/Stats/. so that they can be marked as unsupported when building without statistics.
