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

[opaque pointer type] Add textual IR support for explicit type parameter to load instruction Essentially the same as the GEP change in r230786. A similar migration script can be used to update test cases, though a few more test case improvements/changes were required this time around: (r229269-r229278) import fileinput import sys import re pat = re.compile(r"((?:=|:|^)\s*load (?:atomic )?(?:volatile )?(.*?))(| addrspace\(\d+\) *)\*($| *(?:%|@|null|undef|blockaddress|getelementptr|addrspacecast|bitcast|inttoptr|\[\[[a-zA-Z]|\{\{).*$)") for line in sys.stdin: sys.stdout.write(re.sub(pat, r"\1, \2\3*\4", line)) Reviewers: rafael, dexonsmith, grosser Differential Revision: http://reviews.llvm.org/D7649 llvm-svn: 230794
