+Subject: [PATCH] Fix a llvm compilation error
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Current llvm trunk (https://github.com/llvm/llvm-project)
+will cause the following compilation errors:
+  /home/yhs/work/bcc/src/cc/bcc_debug.cc: In member function ‘void ebpf::SourceDebugger::dump()’:
+  /home/yhs/work/bcc/src/cc/bcc_debug.cc:135:75: error: no matching function for call to
+     ‘llvm::MCContext::MCContext(llvm::Triple&, std::unique_ptr<llvm::MCAsmInfo>::pointer,
+      std::unique_ptr<llvm::MCRegisterInfo>::pointer, llvm::MCObjectFileInfo*,
+      std::unique_ptr<llvm::MCSubtargetInfo>::pointer, std::nullptr_t)’
+     MCContext Ctx(TheTriple, MAI.get(), MRI.get(), &MOFI, STI.get(), nullptr);
+                                                                             ^
+     ......
+
+This is because upstream patch https://reviews.llvm.org/D101921
+refactored MCObjectFileInfo initialization and changed MCContext
+constructor signature.
+
+This patch fixed the issue by following the new code patterns
+in https://reviews.llvm.org/D101921.

+Subject: [PATCH] Remove APInt/APSInt toString() std::string variants
+
+clang 13+ has removed this in favour of a pair of llvm::toString
+() helpers inside StringExtras.h to improve compile speed by avoiding
+hits on <string> header
