From 91e94a7015f14f78809e875c43acbd341d081479 Mon Sep 17 00:00:00 2001 From: shafik Date: Tue, 12 Nov 2019 11:23:38 -0800 Subject: [LLDB][Formatters] Re-enable std::function formatter with fixes to improve non-cached lookup performance Performance issues lead to the libc++ std::function formatter to be disabled. We addressed some of those performance issues by adding caching see D67111 This PR fixes the first lookup performance by not using FindSymbolsMatchingRegExAndType(...) and instead finding the compilation unit the std::function wrapped callable should be in and then searching for the callable directly in the CU.
