-Subject: [PATCH] bpftrace: Add s390x register support
-
-Add s390x specific registers. This is needed for bpftrace builtins like argX,
-regs(), retval etc. This commit provides various functions to perform proper
-offset calculation from the pt_regs context. The builtin functions of
-bpftrace uses these offset functions to generate the proper bytecode for s390x

+Subject: [PATCH] irbuilderbpf.cpp, bpforc.h: Fix compilation with LLVM 11
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Fixes: #1384
+
+Fix the following build errors when compiling with LLVM 11:
