Adding a collector name attribute to Function in the IR. These methods are new to Function: bool hasCollector() const; const std::string &getCollector() const; void setCollector(const std::string &); void clearCollector(); The assembly representation is as such: define void @f() gc "shadow-stack" { ... The implementation uses an on-the-side table to map Functions to collector names, such that there is no overhead. A StringPool is further used to unique collector names, which are extremely likely to be unique per process. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44769 91177308-0d34-0410-b5e6-96231b3b80d8 2007-12-10 03:18:06 +00:00			`; RUN: llvm-as < %s \| llvm-dis \| grep {@f.gc.shadowstack}`
