From a4d58722a47b3712d1f78683371f88a3b6182a59 Mon Sep 17 00:00:00 2001 From: Brad King Date: Fri, 18 Jul 2014 13:57:57 -0400 Subject: cmTarget: Drop internal cache of link interface usage requirements These use a huge amount of memory that accumulates as generation proceeds. On the Unix Makefiles generator, only GetIncludeDirectories and GetCompileDefinitions are even called more than once per target (once for build files, once for dependency scanning preprocessor info). Another approach will be needed to avoid duplicate computation in the cases where it does occur. --- Source/cmTarget.cxx | 246 ++++++++++++++++++---------------------------------- 1 file changed, 83 insertions(+), 163 deletions(-) diff --git a/Source/cmTarget.cxx b/Source/cmTarget.cxx index 07f08de..a812df7 100644 --- a/Source/cmTarget.cxx +++ b/Source/cmTarget.cxx @@ -213,23 +213,6 @@ public: void AddInterfaceEntries( cmTarget const* thisTarget, std::string const& config, std::string const& prop, std::vector& entries);
