From 1ce41edd8da47d7c438c18a819ced3237a2f49f7 Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Tue, 20 Jan 2009 19:11:22 +0000 Subject: Optimize Declarator to avoid malloc/free traffic for the argument list of a function DeclaratorChunk in common cases. This uses a fixed array in Declarator when it is small enough for the first function declarator chunk in a declarator. This eliminates all malloc/free traffic from DeclaratorChunk::getFunction when running on Cocoa.h except for five functions: signal/bsd_signal/sigset, which have multiple Function DeclChunk's, and CFUUIDCreateWithBytes/CFUUIDGetConstantUUIDWithBytes, which take more than 16 arguments. This patch was pair programmed with Steve. llvm-svn: 62599 --- clang/lib/Sema/SemaDecl.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'clang/lib/Sema/SemaDecl.cpp') diff --git a/clang/lib/Sema/SemaDecl.cpp b/clang/lib/Sema/SemaDecl.cpp index 6f731ca..c91d174 100644 --- a/clang/lib/Sema/SemaDecl.cpp +++ b/clang/lib/Sema/SemaDecl.cpp @@ -2772,7 +2772,7 @@ NamedDecl *Sema::ImplicitlyDefineFunction(SourceLocation Loc, Error = Error; // Silence warning. assert(!Error && "Error setting up implicit decl!"); Declarator D(DS, Declarator::BlockContext); - D.AddTypeInfo(DeclaratorChunk::getFunction(false, false, 0, 0, 0, Loc)); + D.AddTypeInfo(DeclaratorChunk::getFunction(false, false, 0, 0, 0, Loc, D)); D.SetIdentifier(&II, Loc); // Insert this function into translation-unit scope. -- cgit v1.1
