From 96a77693be7cfc87208840b2a367362104c43a6b Mon Sep 17 00:00:00 2001 From: Bill Wendling Date: Mon, 29 Apr 2013 22:27:16 +0000 Subject: Emit the TLS intialization functions into a list. Add the TLS initialization functions to a list of initialization functions. The back-end takes this list and places the function pointers into the correct section. This way they're called before `main().' llvm-svn: 180739 --- clang/lib/CodeGen/CodeGenModule.h | 11 +++++++++++ 1 file changed, 11 insertions(+) (limited to 'clang/lib/CodeGen/CodeGenModule.h') diff --git a/clang/lib/CodeGen/CodeGenModule.h b/clang/lib/CodeGen/CodeGenModule.h index 0f4fe8ae51b..ca30096dcb8 100644 --- a/clang/lib/CodeGen/CodeGenModule.h +++ b/clang/lib/CodeGen/CodeGenModule.h @@ -293,6 +293,10 @@ class CodeGenModule : public CodeGenTypeCache { /// priorities to be emitted when the translation unit is complete.
