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. llvm-svn: 44769 2007-12-10 04:18:06 +01:00			`define i32 @main() gc "shadow-stack" {`
