From 4fc9f3e819d64b244f322c213e2dab10bd85636f Mon Sep 17 00:00:00 2001 From: Douglas Gregor Date: Wed, 18 Jan 2012 20:56:22 +0000 Subject: Optimize unqualified/global name lookup in modules by introducing a generational scheme for identifiers that avoids searching the hash tables of a given module more than once for a given identifier. Previously, loading any new module invalidated all of the previous lookup results for all identifiers, causing us to perform the lookups repeatedly. llvm-svn: 148412 --- clang/lib/Serialization/Module.cpp | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'clang/lib/Serialization/Module.cpp') diff --git a/clang/lib/Serialization/Module.cpp b/clang/lib/Serialization/Module.cpp index cb8c9cca06b..bed545a0b26 100644 --- a/clang/lib/Serialization/Module.cpp +++ b/clang/lib/Serialization/Module.cpp @@ -20,8 +20,8 @@ using namespace clang; using namespace serialization; using namespace reader; -ModuleFile::ModuleFile(ModuleKind Kind) - : Kind(Kind), DirectlyImported(false), SizeInBits(0), +ModuleFile::ModuleFile(ModuleKind Kind, unsigned Generation) + : Kind(Kind), DirectlyImported(false), Generation(Generation), SizeInBits(0), LocalNumSLocEntries(0), SLocEntryBaseID(0), SLocEntryBaseOffset(0), SLocEntryOffsets(0), SLocFileOffsets(0), LocalNumIdentifiers(0), -- cgit v1.2.3
