From 0874160bd54fe2a9ab5315d1a68449f97af7761d Mon Sep 17 00:00:00 2001 From: Mike Stump Date: Wed, 4 Mar 2009 13:17:22 +0000 Subject: Add __block codegen testcase. We introduce a temporary flag to enable codegen, until such time as codegen is complete enough to turn on with -fblocks. llvm-svn: 66031 --- clang/lib/CodeGen/CGBlocks.cpp | 14 +++++++++++++- 1 file changed, 13 insertions(+), 1 deletion(-) (limited to 'clang/lib/CodeGen/CGBlocks.cpp') diff --git a/clang/lib/CodeGen/CGBlocks.cpp b/clang/lib/CodeGen/CGBlocks.cpp index 772c9ad2c18..2f1fba02c72 100644 --- a/clang/lib/CodeGen/CGBlocks.cpp +++ b/clang/lib/CodeGen/CGBlocks.cpp @@ -21,6 +21,18 @@ using namespace clang; using namespace CodeGen; +// Temporary code to enable testing of __block variables +// #include "clang/Frontend/CompileOptions.h" +#include "llvm/Support/CommandLine.h" +static llvm::cl::opt +Enable__block("f__block", + // See all the FIXMEs for the various work that needs to be done + llvm::cl::desc("temporary option to turn on __block precessing " + "even though the code isn't done yet"), + llvm::cl::ValueDisallowed, llvm::cl::AllowInverse, + llvm::cl::ZeroOrMore); + + llvm::Constant *CodeGenFunction::BuildDescriptorBlockDecl(uint64_t Size) { const llvm::PointerType *PtrToInt8Ty = llvm::PointerType::getUnqual(llvm::Type::Int8Ty); @@ -448,7 +460,7 @@ llvm::Value *CodeGenFunction::GetAddrOfBlockDecl(const BlockDeclRefExpr *E) { Ty = CGM.getTypes().ConvertType(E->getDecl()->getType()); // FIXME: add support for copy/dispose helpers. - if (1 && E->isByRef()) + if (!Enable__block && E->isByRef()) ErrorUnsupported(E, "__block variable in block literal"); else if (E->getType()->isBlockPointerType()) ErrorUnsupported(E, "block pointer in block literal"); -- cgit v1.2.3
