From 59f7eba2b546e4118434b0ea9de5e08c316a64b1 Mon Sep 17 00:00:00 2001 From: Rafael Espindola Date: Wed, 28 May 2014 18:15:43 +0000 Subject: [pr19844] Add thread local mode to aliases. This matches gcc's behavior. It also seems natural given that aliases contain other properties that govern how it is accessed (linkage, visibility, dll storage). Clang still has to be updated to expose this feature to C. llvm-svn: 209759 --- llvm/lib/Bitcode/Writer/BitcodeWriter.cpp | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'llvm/lib/Bitcode/Writer/BitcodeWriter.cpp') diff --git a/llvm/lib/Bitcode/Writer/BitcodeWriter.cpp b/llvm/lib/Bitcode/Writer/BitcodeWriter.cpp index cc73b842e33..dddcbc6f7e0 100644 --- a/llvm/lib/Bitcode/Writer/BitcodeWriter.cpp +++ b/llvm/lib/Bitcode/Writer/BitcodeWriter.cpp @@ -511,7 +511,7 @@ static unsigned getEncodedDLLStorageClass(const GlobalValue &GV) { llvm_unreachable("Invalid DLL storage class"); } -static unsigned getEncodedThreadLocalMode(const GlobalVariable &GV) { +static unsigned getEncodedThreadLocalMode(const GlobalValue &GV) { switch (GV.getThreadLocalMode()) { case GlobalVariable::NotThreadLocal: return 0; case GlobalVariable::GeneralDynamicTLSModel: return 1; @@ -668,6 +668,8 @@ static void WriteModuleInfo(const Module *M, const ValueEnumerator &VE, Vals.push_back(getEncodedLinkage(A)); Vals.push_back(getEncodedVisibility(A)); Vals.push_back(getEncodedDLLStorageClass(A)); + if (A.isThreadLocal()) + Vals.push_back(getEncodedThreadLocalMode(A)); unsigned AbbrevToUse = 0; Stream.EmitRecord(bitc::MODULE_CODE_ALIAS, Vals, AbbrevToUse); Vals.clear(); -- cgit v1.2.3
