what the restrictions are. Talk to other people about it so that you are
sure it's a good idea.
-#. ``llvm/include/llvm/Intrinsics*.td``:
+#. ``llvm/include/llvm/IR/Intrinsics*.td``:
Add an entry for your intrinsic. Describe its memory access characteristics
for optimization (this controls whether it will be DCE'd, CSE'd, etc). Note
add ability to parse in the type from text assembly
-#. ``llvm/lib/BitCode/Writer/Writer.cpp``:
+#. ``llvm/lib/Bitcode/Writer/Writer.cpp``:
modify ``void BitcodeWriter::outputType(const Type *T)`` to serialize your
type
-#. ``llvm/lib/BitCode/Reader/Reader.cpp``:
+#. ``llvm/lib/Bitcode/Reader/Reader.cpp``:
modify ``const Type *BitcodeReader::ParseType()`` to read your data type
