From dccc03b2423fe65efb5963ae816b99c24fc53374 Mon Sep 17 00:00:00 2001 From: Bill Wendling Date: Sun, 31 Jul 2011 06:30:59 +0000 Subject: Add the 'resume' instruction for the new EH rewrite. This adds the 'resume' instruction class, IR parsing, and bitcode reading and writing. The 'resume' instruction resumes propagation of an existing (in-flight) exception whose unwinding was interrupted with a 'landingpad' instruction (to be added later). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136589 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/ShadowStackGC.cpp | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) (limited to 'lib/CodeGen/ShadowStackGC.cpp') diff --git a/lib/CodeGen/ShadowStackGC.cpp b/lib/CodeGen/ShadowStackGC.cpp index 9807c8cb27..daab89b8f2 100644 --- a/lib/CodeGen/ShadowStackGC.cpp +++ b/lib/CodeGen/ShadowStackGC.cpp @@ -113,9 +113,11 @@ namespace { while (StateBB != StateE) { BasicBlock *CurBB = StateBB++; - // Branches and invokes do not escape, only unwind and return do. + // Branches and invokes do not escape, only unwind, resume, and return + // do.
